Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims the benefit of and priority to U.S. Provisional Patent Application No. 63 / 322,691, filed on March 23, 2022, the entire contents of which, including all references incorporated by reference therein (if any), are incorporated herein by reference for all purposes as if fully set forth herein, except any definition(s), subject matter disclaimer(s), or disclaimer(s), and except to the extent the incorporated material is inconsistent with the express disclosure herein, in which case the language of the disclosure shall control. Technical Field

[0003] The present disclosure generally relates to an intraluminal modular powered medical system. Background Art

[0004] Ventricular assist devices (VADs) generally include left ventricular assist devices (LVADs), right ventricular assist devices (RVADs), or biventricular assist devices (BiVADs). Various VAD designs are known, including intraluminal modular powered medical systems with multiple pumps.

[0005] To provide hemodynamic support, VADs need to displace large amounts of blood, e.g., in the range of one to five liters of blood per minute, and therefore often require large amounts of energy to operate properly. As a result, implantable VADs are typically wired to a power source external to the subject's vasculature, requiring power wires to extend between the VAD and the power source.

[0006] The power lines often enclose: one or more cables or wires to transmit power to one or more of the pump(s); and / or one or more mechanical transmission lines to transmit torque to one or more pumps. Thus, the cross-sectional dimensions of the power lines can be a significant portion of the lumen of the vasculature of the subject in which the VAD is implanted, and thus the power lines can obstruct blood flow in the lumen. This is particularly true when the lumen of the subject's vasculature tapers downstream of the blood flow. The larger the cross-sectional area of ​​the (one or more) power lines, the greater the obstruction to blood flow. Similarly, the more power lines are in the lumen of the vasculature, the greater the obstruction to blood flow. For example, a multi-pump VAD design may require that each pump be wired to a power source, resulting in multiple power lines (either individually or in bundles) passing through the vasculature to transmit power from the power source to the pumps.

[0007] A reduction or even complete absence of blood flow downstream of the transmission line can lead to tissue ischemia and / or other complications. Ischemia, even if only temporary, can cause irreversible damage to tissue. For example, occlusion of femoral artery blood flow for several hours by a VAD implanted via transfemoral access can lead to lower limb ischemia and ultimately lower limb amputation. The problem is further complicated by the increasing burden of atherosclerosis in the peripheral vessels as the population ages, resulting in smaller vessel lumen diameters.

[0008]

[0006] It would therefore be desirable to make improvement(s) to at least some known VADs. Summary of the invention

[0101] The modular pump systems of the present disclosure can be assembled and operated in vivo. As described below, each modular pump system can be delivered to an intraluminal site in an unassembled, undocked configuration via catheter and / or percutaneously for implantation in the vascular system of a subject. Each modular pump system can then be converted from an unassembled, undocked configuration to an assembled, docked configuration and powered for the operation of the pump. After being converted from the assembled, docked configuration to the unassembled, undocked configuration and the pump has been powered off, each modular pump system can also be removed from the intraluminal site via catheter and / or percutaneously to be removed from the vascular system of the subject. In the unassembled, undocked configuration, the pumps are generally arranged in series or one after another, while in the assembled, docked configuration, the pumps are generally arranged in parallel or next to each other. The intraluminal site for implantation includes any lumen of the body, such as the vascular system, including chambers of the heart, hollow organs, and body cavities.

[0102] Figures 1A to 1C is a schematic diagram of a modular pump system 100 (also referred to herein as an intraluminal modular powered medical system) and its components. Figures 1A to 1C , solid lines indicate elements of the modular pump system 100, and dashed lines indicate optional elements of the modular pump system 100. More specifically, Figure 1A A pump dock 110 (also referred to herein as an intraluminal dock or intraluminal control element guide) is schematically illustrated according to an embodiment. Figure 1B First and second pumps 130, 140 (also referred to herein as first and second intraluminal medical devices or first and second intraluminal powerable medical devices) are schematically illustrated according to an embodiment. Figure 1C Schematically illustrated are first and second pumps 130, 140 docked to a pump dock 110 (ie, in a docked configuration) according to an embodiment. Figures 1A to 1C With respect to the modular pump system 100 and components thereof, it will be appreciated, however, that by making necessary changes (one or more) as would be understood by those skilled in the art, as applicable, Figures 1A to 1CThis also applies to the modular pump systems 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300 and their corresponding components as described herein.

[0103] The pump dock 110 provides a structure to which at least one pump can be docked and electrically connected so as to be powered and operated. The pump(s) can be removably dockable (ie, undockable) and removably electrically connectable (ie, electrically disconnectable) to the pump dock 110. Figure 1A A pump dock 110 is shown including first and second dock electrical connectors 112a, 112b, and Figure 1C A pump dock 110 is shown that includes first and second docking electrical connectors 112a, 112b that are electrically connected to first and second pumps 130, 140, respectively. More specifically, the first docking electrical connector 112a is configured to mechanically and electrically connect to the first pump 130 via a first pump electrical connector 133 (also referred to herein as a device electrical connector; described below), thereby docking the first pump 130 to the pump dock 110. Similarly, the second docking electrical connector 112b is configured to mechanically and electrically connect to the first pump 140 via a second electrical connector 143 (also referred to herein as a device electrical connector; described below), thereby docking the second pump 140 to the pump dock 110. The first and second docking electrical connectors 112a, 112b can be electrically disconnected from the first and second pump electrical connectors 133, 143, respectively, so that the first and second pumps 130, 140 can be undocked from the pump dock 110, respectively.

[0104] Thus, the first and second docking station electrical connectors 112a , 112b may not only be configured to provide power to the corresponding first and second pump electrical connectors 133 , 143 when connected thereto, but may also be configured to dock the pump dock 110 to the first and second pumps 130 , 140 .

[0105] The pump dock 110 may include more than one docking station electrical connector for each pump that may be connected thereto.

[0106] The pump dock 110 may include at least one physical docking connector ( Figure 1A and Figure 1C). A docking station physical connector that does not provide power to the pump may be: (i) configured to engage and / or maintain a physical docking interaction between the pump dock 110 and the pump in combination with the docking station electrical connector (i.e., the physical connection components of the docking interaction between the pump dock 110 and the pump are shared by the docking station physical connector and the docking station electrical connector); or (ii) configured to engage and / or maintain a physical docking interaction between the pump dock 110 and the pump without the aid of the docking station electrical connector (i.e., the physical connection components and electrical connection components of the docking interaction between the pump dock 110 and the pump are separated between the docking station physical connector and the docking station electrical connector, respectively). For example, the pump dock 110 may include a docking station electrical connector and a docking station physical connector.

[0107] The pump dock 110 includes at least one control element passage guide (also referred to herein as a guide hole) defined along or through the pump dock 110 and sized and shaped to receive at least one corresponding control element therein, such as the first control element 134 of the first pump 130 or the second control element 144 of the second pump 140 ( Figure 1B ). Once so received, the control elements can be actuated to slidably move along the control element channel guides, thereby causing movement of the corresponding pumps relative to the pump dock 110. For example, the pump dock 110 can include first and second control element channel guides (not shown), each of which is sized and shaped to receive corresponding first and second control elements 134, 144 of the first and second pumps 130, 140, respectively, there along. Actuating the first and second control elements 134, 144, respectively, along the first and second control element channel guides can slideably move the first and second pumps 130, 140, respectively, relative to the pump dock 110.

[0108] The pump dock 110 may include a plurality of control element channel guides, each of which is sized and shaped to receive a corresponding control element of one of the plurality of pumps. Alternatively, the pump dock 110 may include only one control element channel guide, which is sized and shaped to receive all corresponding control elements of the plurality of corresponding pumps.

[0109] The pump dock 110 may optionally include at least one pump receiving surface sized and shaped to mate with a corresponding pump, such as on an outer surface thereof. The pump receiving surface and the pump may be complementary in size and / or shape so as to be structurally consistent with each other when mated together. The pump receiving surface may at least help guide, engage and / or maintain a docking interaction between the pump dock 110 and a pump to be docked or already docked to the pump dock 110. The matching between the pump receiving surface and the pump may be removably matched.

[0110] As the pump and pump dock 110 get closer to each other, such as by sliding the pump toward pump dock 110, the pump gradually engages and / or contacts the corresponding pump receiving surface. As the pump advances along the pump receiving surface, the pump electrical connector gradually engages and eventually establishes electrical connection with the dock electrical connector.

[0111] like Figure 1A and Figure 1C As shown in , the pump dock 110 may include a first pump receiving surface 111a associated with or integrated with a first dock electrical connector 112a, and a second pump receiving surface 111b associated with or integrated with a second dock electrical connector 112b. Figure 3A , Figure 4A , Figure 5A , Fig. 6A , Fig. 7A , Fig. 8A , Fig.9A , Fig. 10A , Fig.11A , Fig. 12A , Fig.13A , Fig.14A , Fig.15A , Fig.16A , Fig.17A , Fig.18A , Fig.19A , Fig. 20A , Fig.21A , Fig.22A Figure 23c Fig.24A , Fig.25A As further shown in the embodiment of, for example, the pump receiving surfaces 111a, 111b are at least partially formed by a protrusion that protrudes from the pump dock in a distal direction (i.e., in a direction opposite to the power connector extending from the pump dock described below). Thus, the first and second docking station electrical connectors 112a, 112b are associated with or integrated with the pump receiving surfaces 111a, 111b, respectively. The first and second docking station electrical connectors 112a, 112b generally define corresponding cavities extending in a proximal direction, opposite to the distal direction of the protrusion.

[0112] When multiple pumps are connectable to the pump dock 110, the protrusions may be positioned and arranged on the pump dock 110 to define one or more pump receiving surfaces that are sized and shaped to mate with only a subset of the multiple corresponding pumps, while the remaining pump(s) are connected to the pump dock 110 without mating with any pump receiving surfaces.

[0113] The one or more pump receiving surfaces may be associated with or integrated with one or more docking station electrical connectors and / or one or more docking station physical connectors. When not associated with or integrated with a pump receiving surface, the electrical connector(s) and / or the docking station physical connector(s) may be located elsewhere on the pump dock 110.

[0114] like Figure 1A and Figure 1C As shown in , the pump dock 110 can also include at least one power connector 113 (also referred to herein as an intraluminal extension) protruding from the pump dock 110, so that when the modular pump system 100 is delivered or implanted, the power connector 113 can extend intraluminally, such as through the vascular system, and connect to a power source (not shown).

[0115] The power connector 113 is connected to the first and second docking station electrical connectors 112a, 112b at its distal portion and is configured to deliver power thereto, respectively, when connected to the pump dock 110, thereby delivering power to the first and second pumps 130, 140. Thus, the power connector may include an electrical conductor, cable, or wire. The proximal portion of the power connector 113 may be deployed intraluminally (e.g., in the vascular system), extraluminally (e.g., outside the vascular system but still within the subject's body), and externally. The proximal portion of the power connector 113 may be manipulated by an operator intraluminally or externally to move the pump dock 110 within the lumen and dock and connect it to the first and second pumps 130, 140, as well as to undock and disconnect the pump dock 110 from the first and second pumps 130, 140.

[0116] The proximal portion of the power connector 113 can be operably connected or removably operably connected to a power source via a wired connection or wireless power transmission. In the case of a wired connection, the power connector 113 can be operably connected to the power source within the lumen (e.g., in the vascular system), outside the lumen (e.g., outside the vascular system but still within the subject's body), and outside the body. In the case of wireless power transmission, the power connector 113 is electrically connected to a receiver coil (not shown) that is configured to receive power from a transmitter coil (not shown) of the power source.

[0117] Alternatively, the power connector 113 itself may be a receiver coil in the shape of a coil, helix, spiral, etc., coupled to the pump dock 110 at any suitable location, such as to the anchor 115, and configured to receive power from a transmitter coil of the power source. The wireless power transfer may include near-field inductive power transfer (e.g., the transmitter coil and the receiver coil are located inside or outside the body when in use) or transcutaneous near-field inductive energy transfer (e.g., the transmitter coil is located outside the body and the receiver coil is located inside the body when in use).

[0118] Still alternatively or additionally, the pump dock 110 , which may be configured to receive power from a power source via a wire or wirelessly, includes a transmitter coil, and the pump(s) include a receiver coil configured to receive power wirelessly from the transmitter coil of the pump dock 110 .

[0119] The pump dock 110 may also include a battery, such as a rechargeable battery, configured to receive power from a power source and supply power to at least one of the pumps 130 , 140 .

[0120] Advantageously, wireless power transmission from outside the body to the modular pump system 100 enables an improved design in which no power cables or wires need to be extended from the pump dock 110 through and / or out of the subject's body to power and / or control the modular pump system 100. This, in turn, at least reduces the risks associated with infection, hemostasis, and other related complications.

[0121] The power source includes any type of suitable power source known in the art, including one or more batteries, an electrical grid, or any other suitable energy supply and / or energy storage device and combinations thereof. The power source may be configured to deliver power to the pump dock via wires and / or wirelessly.

[0122] like Figure 1A and Figure 1C As shown in , the pump dock 110 may also include at least one control component 114 (also referred to herein as an intraluminal extension) extending from the pump dock 110, such that when the modular pump system 100 is delivered or implanted, the control component 114 can extend intraluminally, such as through the vascular system. Thus, the proximal portion of the control component 114 can be deployed intraluminally (e.g., in the vascular system), extraluminally (e.g., outside the vascular system but still within the subject's body), and extracorporeally.

[0123] The control component 114 may be a guide wire or any other suitable wire, cable, etc. (in this case, also referred to herein as a wire control component), the proximal portion of which may be manipulated by an operator within a lumen or outside the body to dock and connect the pump dock 110 to the first and second pumps 130, 140, and undock and disconnect the pump dock 110 from the first and second pumps 130, 140. Thus, the control component 114 may be attachable to and detachable from the pump dock 110 by manipulation by an operator. For example, the wire control component may be screwed to the pump dock 110, so that an operator may rotate the wire control component to screw the wire control component onto the pump dock 110, and to screw the wire control component off the pump dock 110. The control component 114 may also be a snare configured to capture and / or release the pump dock 110. When attached, the wire control component 114 may be used to pull and / or push the modular pump system, including the pump dock 110.

[0124] The control component 114 may also be a catheter (in this case, also referred to herein as a catheter control component) configured to carry (one or more) components and / or (one or more) fluids to the pump dock 110 and thereby optionally deliver them to the lumen. For example, a relatively rigid guide wire (also referred to herein as a rigid guide wire) may be advanced into the catheter control component to provide structural rigidity and / or tactile feedback to the catheter control component for improving intraluminal navigation of the pump dock 110 (docking or undocking with (one or more) pumps), such as in a vascular system. For example, such modulatable and improved structural rigidity and / or hardness of the catheter control component may be useful when an operator needs to push the pump dock 110 toward the first and second pumps 130, 140 (such as for (one or more) docking and / or undocking purposes). In fact, the improved structural rigidity and / or hardness provided by the rigid guide wire to the catheter control component may better transmit thrust to the pump dock 110 without being improperly bent or folded by such force, thereby hindering or preventing the operator's desired manipulation.

[0125] Selection of wires of varying stiffness and / or insertion and removal of (one or more) such wires at least partially within and outside of the catheter-controlled component can modulate the structural stiffness and / or stiffness of the catheter-controlled component, thereby further improving intraluminal navigation and tactile feedback of the pump dock 110.

[0126] The catheter control components may also be used with a fluid flushing device (not shown) to provide flushing solutions (e.g., glucose flushing) to the pump dock 110. For example, the fluid flushing device may provide high pressure fluid (e.g., at a pressure higher than the intraluminal or intracavity pressure in which the device is implanted, such as >140 mm Hg in arterial circulation) from the pump dock 110 to the pump(s) via a fluid connector that may be structurally integrated to the pump(s) electrical connectors 133 and / or 143 to prevent blood from entering the motors of the pumps 130 and / or 140. The fluid flushing device may also provide fluid to the pump(s) 130 and / or 140 in a closed loop to hydraulically drive rotation of the pump impellers (e.g., where the motors are not electric motors).

[0127] like Figure 1A and Figure 1CAs shown in , the pump dock 110 may also include at least one catheter 116 (also referred to herein as an intraluminal extension) protruding from the pump dock 110 so that when the modular pump system 100 is delivered or implanted, the catheter 116 can extend intraluminally, such as through the vascular system. Thus, the proximal portion of the catheter 116 can be deployed intraluminally (e.g., in the vascular system), extraluminally (e.g., outside the vascular system but still within the subject), and in vitro. The proximal portion of the catheter 116 can be manipulated by an operator intraluminally or extracorporeally to move the pump dock 110 within the lumen and dock and connect it to the first and second pumps 130, 140, as well as to undock and disconnect the pump dock 110 from the first and second pumps 130, 140.

[0128] The catheter 116 defines at least one longitudinal channel (also referred to herein as a lumen; not shown) along at least a portion thereof. The catheter 116 is sized and shaped to receive the power connector 113, the control component 114, and / or the first and second control elements 134, 144 (also collectively referred to herein as intraluminal extensions) therein. All intraluminal extensions can be received in a single longitudinal channel. Alternatively, the intraluminal extensions or a combination thereof can be received in corresponding longitudinal channels. For example, the catheter 116 can define two longitudinal channels, each of which is configured to receive one of the first and second control elements 134, 144 therein. The size and / or shape of the longitudinal channels can be in any suitable manner. For example, the cross-sectional dimensions of the longitudinal channel can be designed to be slightly larger than the cross-sectional dimensions of a given control element to allow the control element to fully translate therethrough while limiting any free space in which the control element may bend, twist, etc.

[0129] like Figure 1A and 1C As shown in , the pump dock 110 may also include an anchor 115 configured to anchor the pump dock 110 (and the modular pump system 100 when the first and second pumps 130, 140 are docked to the pump dock 110) within a lumen, such as at an intraluminal implantation site in the aorta or a chamber of the heart. For example, the anchor may secure the pump dock 110 to a wall of the vascular system by applying a force to the pump dock 110. The pump dock 110 has a compact configuration for intraluminal delivery (such as by transcatheter surgery) and an expanded configuration for anchoring the pump dock 110 within a lumen. The cross-sectional dimensions of the anchor in the compact configuration are smaller than the cross-sectional dimensions of the anchor 115 in the expanded configuration.

[0130] The anchor 115 can be self-expandable (e.g., made of a memory material such as nitinol) such that the anchor automatically converts from a compact configuration to an expanded configuration at the intraluminal implantation site (e.g., by withdrawing from a sheath or sheath). When self-expandable, the anchor 115 can be biased or overcomeably biased toward the expanded configuration. For example, the anchor can be an anchor assembly described in International Patent Application No. PCT / ZA2020 / 050,022, which is incorporated herein by reference in its entirety, including all references incorporated by reference therein, for all purposes, as if fully set forth herein, except for any definitions, subject disclaimers or denials, and except to the extent that the incorporated material is inconsistent with the express disclosure herein, in which case the language in the present disclosure shall prevail.

[0131] Alternatively, anchor 115 may also be mechanically expandable. For example, a balloon catheter deployed within anchor 115 may be inflated to partially or completely transform anchor 115 from a compact configuration to an expanded configuration (in which case anchor 115 is made of a "non-memory" material).

[0132] Still alternatively, the anchor 115 can be operably coupled to an anchor actuation handle (not shown) that is configured to be manipulated by an operator to transition the anchor 115 from a compact configuration to an expanded configuration or cause such transition (in which case the anchor 115 can be made of a memory material that biases the anchor 115 toward the expanded configuration) and / or transition from an expanded configuration to a compact configuration or cause such transition.

[0133] The anchor 115 can be releasably coupled to the pump dock 110 and thereby releasable from the pump dock 110 when the actuator rod or actuator wire is actuated, as described in the mammalian body conduit intraluminal device and lumen wall anchor assembly described in International Patent Application No. PCT / US2021 / 012,083, which is incorporated herein by reference in its entirety, including all references incorporated by reference therein, for all purposes as if fully set forth herein, except for any definitions, subject disclaimers, or disclaimers, and except to the extent the incorporated material is inconsistent with the express disclosure herein, in which case the language of the disclosure shall control.

[0134] like Figure 1BAs shown in , the modular pump system 100 includes at least one pump (also referred to herein as an intraluminal medical device and an intraluminal powered medical device), such as first and second pumps 130, 140. The first pump 130 (and its components, if applicable) is similar to the second pump 140 (and its components, if applicable), so only the first pump 130 (and its components, if applicable) will be described below. The skilled person will recognize that the description of the first pump 130 (and its components, if applicable) is applicable to the second pump 140 (and its components, if applicable) by making (one or more) necessary changes (if applicable) that are understandable to the skilled person.

[0135] The first pump 130 includes: a first impeller 131 for moving fluid within the lumen; a first motor 132, which is operably coupled to the first impeller 131 either directly or indirectly (for example, via a gearbox) for rotating the first impeller 131; a first pump electrical connector 133 (also referred to herein as a first device electrical connector), which is operably connected to the first motor 132 for delivering power to the first motor 132 and is operably connectable or removably connectable to the first docking station electrical connector 112a for receiving power from the first docking station electrical connector 112a; and a first control element 134 (also referred to herein as an intraluminal extension) attached to the first pump 130 and protruding from the first pump 130 for moving the pump 130 within the lumen. The first pump 130 is configured for intraluminal delivery when undocked from the pump dock 110 (i.e., in an unassembled, undocked configuration) and is configured to be docked to the pump dock 110 intraluminally (i.e., in an assembled, docked configuration), such as in the vasculature of a subject.

[0136] The first impeller 131 may be an axial flow impeller, a peripheral impeller, a mixed flow impeller or a radial impeller. Preferably, the first impeller is an axial flow impeller of an axial flow pump.

[0137] The first motor 132 may be an electric motor, such as a brushless electric motor.

[0138] like Figure 1BAs shown in , the first pump 130 may include at least one control element (also referred to herein as an intraluminal extension), such as a first control element 134. The first control element 134 can be connected to any location of the first pump 130 and protrude from the location. For example, the first control element 134 can be connected to the first pump electrical connector 133 of the first pump 130 and protrude therefrom. Alternatively, the first control element 134 can be connected to a corresponding pump physical connector (not shown; described below) and protrude therefrom. The first control element 134 extends from the first pump 130 so that when the modular pump system 100 is delivered or implanted, the first control element 134 can extend intraluminally, such as through the vascular system. Therefore, the proximal portion of the first control element 134 can be deployed intraluminally (e.g., in the vascular system), extraluminally (e.g., outside the vascular system but still in the subject's body), and in vitro.

[0139] Protruding from the first pump 130 and slidably received in a corresponding control element channel guide of the pump dock 110 , the first control element 134 can be manipulated by an operator at its proximal portion to dock the first pump 130 to the pump dock 110 and undock the first pump 130 from the pump dock 110 .

[0140] More specifically, when the first pump 130 is positioned distally relative to the pump dock 110, the proximal portion of the first control element 134 can be pulled away relative to the pump dock 110 to dock the first pump 130 to the pump dock 110 and connect the first pump electrical connector 133 to the first dock electrical connector 112a. Conversely, the proximal portion of the first control element 134 can be pushed toward the pump dock 110 to undock the first pump 130 from the pump dock 110 and disconnect the first pump electrical connector 133 from the first dock electrical connector 112a.

[0141] Alternatively, when the first pump 130 is positioned proximally relative to the pump dock 110, the proximal portion of the first control element 134 can be pushed toward the pump dock 110 to dock the first pump 130 to the pump dock 110 and connect the first pump electrical connector 133 to the first dock electrical connector 112a. Conversely, the proximal portion of the first control element 134 can be pulled toward the pump dock 110 to undock the first pump 130 from the pump dock 110 and disconnect the first pump electrical connector 133 from the first dock electrical connector 112a.

[0142] When the modular pump system 100 is delivered and implanted in the body, when the pump dock 110 is located in a lumen (such as in the vascular system of a subject), docking and connection of the first pump 130 to the pump dock 110 and undocking and disconnection of the first pump 130 from the pump dock 110 can be performed within the lumen, and the first control element 134 extends from the lumen along it to position its proximal portion at an extraluminal or extracorporeal location for manipulation by an operator.

[0143] The first control element 134 may be a guide wire or any other suitable wire, cable, etc. (in this case, also referred to herein as a first wire control element and a wire control element) configured to be manipulated by an operator at its proximal portion. Manipulation of the first control element 134 causes the corresponding first pump 130 to move relative to the pump dock 110 so as to dock and electrically connect the first pump 130 to the pump dock 110 for operation, and to undock and electrically disconnect the first pump 130 from the pump dock 110. The first wire control element 134 may be attachable or removably attachable to the first pump 130 and detachable or removably detachable from the first pump 130 by manipulation by the operator. For example, the first wire control element 134 may be screwed onto the first pump 130 so that the operator can rotate the first wire control element 134 to screw the first wire control element 134 onto the first pump 130 and unscrew the first wire control element 134 from the first pump. The first control element 134 may also be a looper configured to capture and / or release the first pump 130. When attached, the first wire control element 134 may be used to pull and / or push the modular pump system 100 , including the first pump 130 .

[0144] Since the first pump 130 receives power via the pump dock 110 when electrically connected to the pump dock 110, the first control element 134 does not need to be configured to be electrically conductive to power the first pump 130, as is the case, for example, for the modular mammalian body implantable fluid flow influencing device described in International Patent Application No. PCT / ZA2020 / 050,022. International Patent Application No. PCT / ZA2020 / 050,022 is incorporated herein by reference in its entirety, including all references incorporated by reference therein, for all purposes as if fully set forth herein, except for any definitions, subject matter disclaimers or disclaimers, and except to the extent the incorporated material is inconsistent with the express disclosure herein, in which case the language of the present disclosure controls.

[0145] Assuming that the first control element 134 is not configured to be conductive, its cross-sectional dimensions are smaller than when it is required to be conductive (e.g., by integrating an electrically conductive material). Advantageously, this reduction in cross-sectional dimensions enables the first control element 134 to have a reduced intraluminal cross-sectional footprint and, therefore, reduced blood flow obstruction when routed through the vascular system. The reduction in the cross-sectional dimensions of the control elements and the intraluminal cross-sectional footprint is also advantageous when the implantable modular pump system 100 includes multiple pumps, each having a corresponding control element extending therefrom into the lumen of the vascular system. In this case, multiple control elements can collectively cause blood flow obstruction, and providing power to the pump via the pump dock enables the cross-sectional footprint of the control elements within the overall lumen and their associated blood flow obstruction to be reduced.

[0146] The first control element 134 can also be a catheter configured to carry (one or more) components and / or (one or more) fluids to the first pump 130 and thereby optionally deliver them into the lumen (in this case, also referred to herein as the first catheter control element and the catheter control element). For example, a relatively rigid guidewire (also referred to herein as a rigid guidewire) can be routed in the first catheter control element to provide structural rigidity and / or tactile feedback to the first catheter control element for improving intraluminal navigation of the first pump 130 (docked to or undocked from the pump dock 110), such as in a vascular system. For example, when the first pump 130 needs to be pushed toward the pump dock 110 by an operator (such as for (one or more) docking and / or undocking purposes), this modulatable and improved structural rigidity and / or hardness of the first catheter control element can be useful. Indeed, the improved structural rigidity and / or stiffness provided to the first catheter control element by the rigid guidewire may better transmit thrust forces to the pump dock 110 without unduly bending or collapsing due to such forces, thereby hindering or preventing intended manipulation by the operator.

[0147] Selection of wires of varying stiffness and / or insertion and removal of (one or more) such wires at least partially within and outside the first catheter control element can modulate the structural stiffness and / or stiffness of the first catheter control element, thereby further improving intraluminal navigation and tactile feedback of the first pump 130.

[0148] The first catheter control element can also be used with a fluid flushing device (not shown) to provide a flushing solution (e.g., a glucose flush) to the first pump 130. For example, the fluid flushing device can provide a high-pressure fluid (e.g., at a pressure higher than the intraluminal or intracavity pressure in which the device is implanted, such as >140 mm Hg in the arterial circulation) to the first pump 130 to prevent blood from entering the first motor 132. The fluid flushing device can also provide fluid to the first pump 130 in a closed loop to hydraulically drive the rotation of the first impeller 131 (e.g., where the motor is not an electric motor).

[0149] like Figure 1B As shown in , the first pump 130 may include at least one pump electrical connector (also referred to herein as a first device electrical connector and a device electrical connector), such as a first pump electrical connector 133. The first pump electrical connector 133 is configured to be removably or non-removably electrically connected to a corresponding first docking station electrical connector 112a in a manner such that the pump electrical connector 133 may terminate within, around, and / or near the docking station electrical connector 112a. When the first pump 130 is properly docked to the pump dock 110, the first docking station electrical connector 112a delivers power to the first pump electrical connector for rotating the first impeller 131 of the first pump 130.

[0150] Thus, the first pump electrical connector 133 may be configured not only to receive power therefrom when connected to the corresponding first docking station electrical connector 112a , but also to dock the first pump 130 to the pump dock 110 .

[0151] The first pump 130 may include multiple pump electrical connectors, such as two or three pump connectors, each pump connector being configured to operate in a different phase.

[0152] The first pump 130 may include at least one pump physical connector ( Figure 1B ). A pump physical connector that does not receive power from the pump dock 110 is configured to be cooperatively connected to a corresponding dock physical connector of the pump dock 110, either removably or non-removably. Similar to the dock physical connector, the pump physical connector can be: (i) configured to engage and / or maintain a physical docking interaction between the pump and the pump dock 110 in combination with the pump electrical connector (i.e., the physical connection components of the docking interaction between the pump and the pump dock 110 are shared by the pump physical connector and the pump electrical connector); or (ii) configured to engage and / or maintain a physical docking interaction between the pump and the pump dock 110 without the aid of the pump electrical connector (i.e., the physical connection components and electrical connection components of the docking interaction between the pump and the pump dock 110 are separated between the pump physical connector and the pump electrical connector, respectively). For example, the first pump 130 may include a pump electrical connector and a pump physical connector.

[0153] The first pump 130 may include one or more pump electrical connectors and / or one or more pump physical connectors. For example, the first pump 130 may include at least one first pump electrical connector 133 configured to power the first pump 130 via the pump dock 110 and physically dock the first pump 130 to the pump dock 110. Alternatively, the first pump 130 may also include at least one first pump electrical connector 133 configured to power the first pump 130 via the pump dock 110 and at least one pump physical connector configured to physically dock the first pump 130 to the pump dock 110.

[0154] When one or more pump electrical connectors and / or one or more pump physical connectors are provided to the first pump 130, a corresponding number of (one or more) docking electrical connectors and / or (one or more) docking physical connectors are provided to the pump dock 110, including a corresponding number of (one or more) optional pump receiving surfaces.

[0155] The pump dock 110 and the first pump 130 can be docked together and can be connected together to provide power for operation to the first pump 130. More specifically, the pump dock 110 and the first pump 130 can be docked together and can be connected together via: (i) cooperative interengagement between the dock electrical connector 112a and the first pump electrical connector 133; (ii) optional cooperative interengagement between the dock physical connector and the first pump physical connector; and (iii) optional cooperative interengagement between the pump receiving surface 111a and the first pump 130, such as on an outer surface thereof.

[0156] This cooperative interengagement allows for (i) sufficiently strong docking interaction between the pump dock 110 and the first pump 130 to at least reduce unnecessary undocking and / or unnecessary disconnection of the first pump 130 from the pump dock 110 during operation; and (ii) providing proper orientation of the first pump 130 (together with or in combination with at least one other pump, such as the second pump 140) to obtain a blood outflow volume sufficient to achieve the intended medical purpose.

[0157] Although pumps are described herein as being dockable and connectable to and undockable from a pump dock, it will be appreciated that the docking interaction between a pump and a pump dock may be otherwise. For example, one or more pumps may be non-removably dockable and / or non-removably connectable to a pump dock.

[0158] As shown herein, the pumps docked to the pump dock are arranged in a parallel or alongside each other configuration, wherein the pumps are arranged longitudinally in parallel relative to each other.

[0159] Alternatively, the pumps docked to the pump dock may be arranged in a trumpet-like configuration, wherein distal portions of the pumps are separated by a greater distance than proximal portions of the pumps.

[0160] Still alternatively, the pumps docked to the pump dock can be arranged in a reverse flared configuration, wherein the proximal portions of the pumps are separated by a greater distance than the distal portions of the pumps. The arrangement of the pumps in parallel, flared, and reverse flared configurations depends on the design and integration of the dock electrical connector, pump electrical connector, dock physical connector, pump physical connector, and pump receiving surfaces, such as their respective angles relative to the body of the pump dock.

[0161] Although the modular pump system 100 as shown and described herein includes a pump docking station 110 and two pumps (i.e., Figures 1A to 1C ) or three pumps (i.e. FIG. 3A to FIG. 29C ), but the modular pump system 100 can be configured to include any number of pumps.

[0162] Pumps described and illustrated herein include any implantable blood or heart pump, such as axial flow pumps, positive displacement pumps, and centrifugal pumps.

[0163] Although the present disclosure refers to a "pump", those skilled in the art will readily recognize that the pump can actually be any other medical device and equivalent structure that can be docked and connected to a pump dock for operation or can be undocked and disconnected from a pump dock. This includes any medical device and equivalent structure that is sized and shaped to be delivered within a lumen, assembled within a lumen, or docked to a pump dock within a lumen, operably connected to a pump dock within a lumen for operation, implanted within a lumen, and / or removed within a lumen. This also includes any medical device and equivalent structure that can be slidably moved relative to a pump dock to dock to operate with the pump dock, such as slidably moved inside a lumen.

[0164] Such other medical devices and equivalent structures include any device that affects blood flow, balloon pump systems, intraluminal occluders, intravascular prostheses, implantable pacemakers, interatrial shunt devices, valve replacement systems, and / or valvuloplasty systems.

[0165] Figure 2A A schematic flow chart of a method 200 of implanting a modular pump system into a lumen, such as the vasculature (including the lumen of the aorta and chambers of the heart), a hollow organ, and a body cavity, according to an embodiment is shown. Figure 2A , solid lines indicate elements of method 200 , and dashed lines indicate optional elements of method 200 .

[0166] Method 200 for implanting a modular pump system (also referred to herein as an intraluminal modular powered medical system) into an intraluminal implantation site in the lumen of a subject comprises: delivering the modular pump system to the intraluminal implantation site at 201, the modular pump system comprising a pump dock (also referred to herein as an intraluminal dock or an intraluminal control element guide) having a dock electrical connector and a pump (also referred to herein as an intraluminal medical device and an intraluminal powered medical device) having a pump electrical connector (also referred to herein as a device electrical connector) electrically connectable to the dock electrical connector; and connecting the dock electrical connector and the pump electrical connector together within the lumen at 203 for powering the pump.

[0167] Connecting 203 intraluminally can include manipulating a control element of the pump at 205A to connect the pump electrical connector and the docking station electrical connector together intraluminally for powering the pump. For example, the control element can be positioned and manipulated intraluminally, in vivo (but not in the lumen), and / or extracorporeally at its proximal portion. The control element can be in a slidable relationship with the pump dock, such as by slidably passing through the pump dock, such that the control element is manipulated to slidably move the pump relative to the pump dock.

[0168] Connecting 203 may include manipulating an intraluminal extension of the pump dock at 205B to connect the dock electrical connector and the pump electrical connector together intraluminally for powering the pump. For example, the intraluminal extension may be positioned and manipulated intraluminally, in vivo (but not in the lumen), and / or extracorporeally at its proximal portion. The pump dock may be in a slidable relationship with the pump, such as by a control element disposed thereon that slidably passes through the pump dock such that the intraluminal extension is manipulated to slidably move the pump dock relative to the pump.

[0169] Method 200 may also include supplying power to the pump via the pump dock by electrically connecting the pump dock to a power source, such as at a proximal portion of a power connector of the pump dock, at 207A, or by wirelessly transferring energy from the power source to the pump dock, at 207B.

[0170] Delivering 201 may include obtaining an intraluminal access opening at 209 for delivering the modular pump system through the opening to an intraluminal implantation site, such as percutaneous delivery.

[0171] Delivery 201 may also include: introducing a sheath or catheter that at least partially contains the modular pump system into the lumen through an intraluminal access opening at 211A; navigating or guiding the sheath or catheter through the lumen to its intraluminal implantation site at 211B, and withdrawing (or causing the withdrawal of) the modular pump assembly from the intraluminal sheath or catheter at its intraluminal implantation site at 211C.

[0172] The method 200 may also include anchoring the modular pump system at the intraluminal implantation site at 213 , such as via an anchor provided on a pump dock.

[0173] Delivery 201 may also include, at 215 , removing the sheath or catheter from the lumen after the modular pump system is withdrawn (or caused to be withdrawn) from the intraluminal implantation site.

[0174] Delivery 201 may also include closing the intraluminal passage opening at 217 , such as by surgery.

[0175] Docking the pump to the pump dock can be performed by pulling the control element of the pump to move the pump toward the pump dock for docking and connecting the pump to the pump dock (i.e., when the pump is positioned distally relative to the pump dock, the pump electrical connector (also referred to herein as the device electrical connector) is disposed proximally of the pump, and the dock electrical connector is disposed distally of the pump dock). Alternatively, the control element of the pump can be pushed to move the pump toward the pump dock for docking and connecting the pump to the pump dock (i.e., when the pump is positioned proximally relative to the pump dock, the pump electrical connector is disposed circumferentially of the pump, and the dock electrical connector is disposed circumferentially of the pump dock).

[0176] Docking the pump dock to the pump can also be performed by pushing the intraluminal extension of the pump dock (including the power connector) (e.g., using a push rod resting on the pump dock) to move the pump dock toward the pump for docking and connecting the pump dock to the pump (i.e., when the pump dock is positioned proximally relative to the pump, the docking station electrical connector is deployed distally of the pump dock, and the pump electrical connector (also referred to herein as the device electrical connector) is deployed proximally of the pump). Alternatively, the power control element of the pump dock can be pulled to move the pump dock toward the pump for docking and connecting the pump dock to the pump (i.e., when the pump dock is positioned distally relative to the pump, the docking station electrical connector is deployed circumferentially of the pump, and the docking station electrical connector is positioned circumferentially of the pump dock).

[0177] It will be appreciated that the control element of the pump and / or the power control element of the pump dock may be manipulated (eg, by pulling and / or pushing either or both) to effectuate docking between the pump and the pump dock.

[0178] In some embodiments, wherein the modular pump system includes two pumps (i.e., first and second pumps having first and second control elements, respectively), the first and second pumps can be implanted from an intraluminal implantation site by respectively manipulating the first and second control elements in accordance with the method of implanting the modular pump system described herein, by making (one or more) necessary changes (if applicable) that are understandable to those skilled in the art.

[0179] Figure 2B A schematic flow chart of a method 1400 of removing a modular pump system from a lumen, such as from the vasculature (including the lumen of the aorta and chambers of the heart), hollow organs, and body cavities, according to an embodiment is shown. Figure 2B , solid lines indicate elements of method 1400 , and dashed lines indicate optional elements of method 1400 .

[0180] Method 1400 removes a modular pump system (also referred to herein as an intraluminal modular powered medical system) from an intraluminal implantation site in the lumen of a subject, the modular pump system comprising a pump dock (also referred to herein as an intraluminal dock or an intraluminal control element guide) having a dock electrical connector and a pump (also referred to herein as an intraluminal medical device and an intraluminal powered medical device) having a pump electrical connector (also referred to herein as a device electrical connector) that can be electrically disconnected from the dock electrical connector, the method comprising: disconnecting the dock electrical connector and the pump electrical connector from each other in the lumen to power off the pump at 1401; and retrieving the modular pump system from the intraluminal implantation site at 1403.

[0181] Intraluminal disconnection 1401 may include manipulating a control element of the pump at 1405A to disconnect the pump electrical connector and the docking station electrical connector from each other within the lumen for de-energizing the pump. For example, the control element may be positioned and manipulated at its proximal portion within the lumen, within the body (but not within the lumen), and / or outside the body. The control element may be in a slidable relationship with the pump dock, such as by being slidable through the pump dock, such that the control element is manipulated to slidably move the pump relative to the pump dock.

[0182] Connecting 1401 may include manipulating an intraluminal extension of the pump dock at 1405B to disconnect the dock electrical connector and the pump electrical connector from each other within the lumen for powering off the pump. For example, the intraluminal extension may be positioned and manipulated within the lumen, within the body (but not within the lumen), and / or outside the body at its proximal portion. The pump dock may be in a slidable relationship with the pump, such as by a control element disposed thereon that slidably passes through the pump dock so that the intraluminal extension is manipulated to slidably move the pump dock relative to the pump.

[0183] Method 1400 may also include interrupting power supply to the pump via the pump dock at 1407A by electrically disconnecting the pump dock from the power source, such as at a proximal portion of a power connector of the pump dock, or by interrupting wireless energy transfer from the power source to the pump dock at 1407B.

[0184] Retrieval 1403 may include obtaining an intraluminal access opening at 1409 for retrieval of the modular pump system therethrough from the intraluminal implantation site, such as percutaneous retrieval.

[0185] Retrieval 1403 may also include: introducing a sheath or catheter into the lumen through the intraluminal access opening at 1411A; navigating or guiding the sheath or catheter through the lumen to its intraluminal implantation site at 1411B; and at least partially removing (or causing removal of) the modular pump assembly from the lumen into the sheath or catheter at the intraluminal implantation site at 1411C.

[0186] The method 1400 may also include, at 1413, unanchoring the modular pump system from the intraluminal implantation site, such as via an anchor provided on a pump dock.

[0187] The method 1400 may also include, at 1415 , removing from the lumen the sheath or catheter at least partially containing the modular pump system therein.

[0188] The method 1400 may also include closing the intraluminal access opening at 1417 , such as surgically.

[0189] The pump may be undocking from the pump dock by pushing a control element of the pump to move the pump away from the pump dock, for undocking and disconnecting the pump from the pump dock (i.e., when the pump is positioned distally relative to the pump dock, the pump electrical connector (also referred to herein as the device electrical connector) is disposed proximally of the pump, and the dock electrical connector is disposed distally of the pump dock). Alternatively, the pump control element may be pulled to move the pump away from the pump dock, for undocking and disconnecting the pump from the pump dock (i.e., when the pump is positioned proximally relative to the pump dock, the pump electrical connector is disposed circumferentially of the pump, and the dock electrical connector is disposed circumferentially of the pump dock).

[0190] The pump dock can also be undocking from the pump by pulling the intraluminal extension of the pump dock (including the power connector) to move the pump dock away from the pump, for undocking and disconnecting the pump dock from the pump (i.e., when the pump dock is positioned proximally relative to the pump, the docking electrical connector is deployed distally of the pump dock, and the pump electrical connector (also referred to herein as the device electrical connector) is deployed proximally of the pump). Alternatively, the power control element of the pump dock can be pushed (e.g., using a push rod resting on the pump dock) to move the pump dock away from the pump, for undocking and disconnecting the pump dock from the pump (i.e., when the pump dock is positioned distally relative to the pump, the docking electrical connector is deployed circumferentially of the pump, and the docking electrical connector is deployed circumferentially of the pump dock).

[0191] It will be appreciated that the control element of the pump and / or the power control element of the pump dock may be manipulated (eg, by pulling and / or pushing either or both) to effect undocking of the pump from the pump dock.

[0192] In some embodiments, wherein the modular pump system includes two pumps (i.e., first and second pumps having first and second control elements, respectively), the first and second pumps can be removed from the intraluminal implantation site by respectively manipulating the first and second control elements in accordance with the method of removing the modular pump system described herein, by making (one or more) necessary changes (if applicable) that are understandable to a person skilled in the art.

[0193] In some embodiments, where the modular pump system includes more than one pump, it will also be appreciated that each pump electrical connector is connectable to and disconnectable from a corresponding connector of the docking station electrical connector (i) simultaneously and (ii) relative to each other in a stepwise manner (e.g., by connecting or disconnecting a first pump, then connecting or disconnecting a second pump, and so on), e.g., depending on how an operator respectively manipulates the proximal portion of the corresponding control element. Thus, the same is true for docking and undocking of the pumps relative to the pump dock.

[0194] Intraluminal implantation sites may include implantation sites located in the lumen of a body vessel, such as in the lumen of the vasculature, including the lumen of the aorta and chambers of the heart, hollow organs, and body cavities.

[0195] The modular pump system is configured to be delivered via a catheter for implantation at an intravascular implantation site and retrieved via a catheter for removal from the intravascular implantation site. For example, the intravascular implantation site may be the lumen of the aorta or a chamber of the heart.

[0196] For implantation, in use, a modular pump system contained in a catheter (or sheath) is delivered with at least one pump undocked from and thus disconnected from a pump dock (i.e., in an undocked configuration). The catheter (or sheath) is routed through the vasculature up to or near an intravascular implantation site. The modular pump system is then withdrawn from the catheter (or sheath) at or near the implantation site, and the pump is docked to the pump dock, resulting in a docked configuration.

[0197] For removal, in use, the modular pump system in the docked configuration is retrieved from the intravascular implantation site by undocking and thereby disconnecting at least one pump from the pump docking station. The modular pump system in the undocked configuration is then taken out into a catheter (or sheath) and the catheter is removed from the vascular system.

[0198] Although implantation and removal of the modular pump system is described herein as being performed via a transcatheter procedure (either percutaneous or non-percutaneous), it will be appreciated that the modular pump system may also be implanted and removed without the use of a catheter (or sheath).

[0199] For implantation, in use, the modular pump system is routed through the vasculature to an intravascular implantation site without being contained in a catheter (or sheath), and at least one pump is docked to a pump docking station. Routing of the pump in the vasculature can be performed by pulling and / or pushing at least one control element and / or by sheathing the pump, as is known in the art.

[0200] For removal, in use, at least one pump is undocked from the pump docking station and the modular pump system is removed from the vasculature without being contained in a catheter (or sheath). Retrieval of the pump may be performed by pulling at least one control element and / or by sheathing the pump.

[0201] Figures 3A-5C A modular pump system 300 according to an embodiment is illustrated. The modular pump system 300 may be similar or identical in form and / or function to the modular pump system 100. Therefore, parts and components of the modular pump system 300 will not be described in detail herein. Figures 3A-3DAs shown in FIG. 3 , the modular pump system 300 includes a first pump 330, a second pump 340, and a third pump 350, and a pump docking station 310 to which the three pumps can be docked. Figure 3A and Figure 3D As shown in FIG. 1 , in particular, pump dock 310 includes an anchor 315 configured to anchor or secure pump dock 310 (eg, pumps 330 , 340 , and 350 docked thereto) within a lumen of a subject's anatomy.

[0202] Figure 3A Illustrated is a pump 330 docked to the pump dock 310 , as well as pumps 340 and 350 operably coupled to but not yet docked to the pump dock 310 . Figure 3B All three pumps 330, 340, 350 are illustrated as being docked to a pump dock. The pumps 330, 340, 350 have pump electrical connectors 333, 343, 353 (also referred to herein as device electrical connectors), respectively. Each pump electrical connector 333, 343, 353 is a single pin with three conductive segments or rings CR. Each conductive segment or ring CR is suitable for a different phase of a motor (not shown) of the modular pump system 300. Although in this embodiment, each pump includes a single pin with three conductive segments or rings CR, in some embodiments, each pump 330, 340, 350 may include multiple pins, for example, three pins, wherein each of the three pins is suitable for a different phase of the motor (e.g., each pin has a conductive segment or ring).

[0203] Figure 3C Pump 330 is illustrated (which may be the same or similar in form and / or function to pumps 340 and 350, including pump electrical connector 133), while Figure 3D The pump electrical connector 133 is shown in greater detail. As shown, the pump electrical connector 133 is located at the end of the pump 330 so that the pump 330 can be advanced (eg, pushed or pulled) toward and into contact with the pump receiving surface 311a (when present) and the docking station electrical connector 312A.

[0204] Figure 4A -C illustrates this process. Figure 4A , pump 330 is docked to pump dock 310, and pump 340 is in an undocked configuration with its control element 344 traveling through dock electrical connector 312b, as shown in reference Figures 5A-5C shown and described in further detail. Figure 4B The pump 340 is illustrated in an intermediate configuration between the undocked configuration and the docked configuration. Figure 4C A pump 340 is illustrated docked to a pump dock 310 . Figure 4D The docking station 310 is shown Figure 4A Top view cross section taken at AA in the figure. Figure 4DLumens (also referred to herein as control element receiving volumes CRV and control element channel guides) are shown, distributed circumferentially around the central axis of the pump dock 310 and configured to receive control elements 334, 344, 354 for connection and docking to each pump 330, 340, 350. When the pumps 330, 340, 350 are docked and connected in this way, the control elements 334, 344, 355 of the pumps 330, 340, 350 extend along the corresponding lumens through the dock 310 and beyond the dock 310 to reach the operator for manipulation. Moreover, Figure 4D and Figures 5A-5C It is the inner or central lumen CL through which the electrical connector EC can be routed.

[0205] As shown, the pump dock 310 defines a pump receiving surface 311a, 311b, 311c for each pump 330, 340, 350, respectively, and three docking station electrical connectors 312a, 312b, 312c (also referred to herein as docking station electrical connectors) to receive pump electrical connectors 333, 343, 353 and their corresponding control elements 334, 344, 354, respectively, as shown in FIG. Figures 5A-5C The docking sequence shown in FIG is relatively more detailed. Figures 4A-4C and Figures 5A-5C As shown in the figure, the pump receiving surfaces 311a, 311b, 311c are at least partially defined by a protrusion that protrudes distally in a direction opposite to the catheter 316. As shown, each docking station electrical connector 312a, 312b, 312c defines a cavity C, which is configured to receive (and circumferentially surround) each pump electrical connector 333, 343, 353, including its corresponding control element 334, 344, 354. Each cavity C defines a receiving volume RV for each pin of the pump electrical connector 333, 343, 353 and its corresponding conductive segment or ring CR (including the conductive receiving segment CRS), thereby jointly providing a physical mating or fixation of the components. The cavity C may include a fluid flushing port (not shown) provided at the bottom thereof for draining the fluid contained in the cavity C and the receiving volume RV when the pump electrical connector is inserted therein to establish an electrical connection.

[0206] In this embodiment, each conductive receiving segment CRS includes a compressive conductive component, such as a spring, a coil, etc., configured to align with and circumferentially surround its corresponding conductive ring CR and establish sufficient electrical contact when each pump electrical connector 333, 343, 353 is docked. For example, the pump electrical connector 333, 343, 353 (conductive segment or ring CR) and / or the docking station electrical connector 312a, 312b, 312c can be spring-loaded to provide sufficient contact force between the connectors to establish an electrical connection, even in the presence of blood. In this way, for example, each conductive coil can compensate for any misalignment, tolerance variations, and / or matching surface irregularities, thereby providing electrical contact redundancy. In addition, in some embodiments, the compressive conductive component can assist in the coupling or fixation of the pump electrical connector 333, 343, 353 within the cavity C through a compressive force. Coupled to each conductive receiving segment CRS and extending therefrom is an electrical connector EC (e.g., a wire, cable, etc.) configured to establish an electrical connection with its corresponding conductive ring CR, such as Figures 5A-5C Each electrical connector EC is then routed toward and electrically coupled to a power connector (not shown), similar to the power connector 113 described above.

[0207] In addition to defining a pin receiving volume PRV to receive each pump electrical connector 333, 343, 353 pin, each cavity C also defines a control element receiving volume CRV (also referred to herein as a control element channel guide) configured to receive a control element 334, 344, 354, as shown. In this manner, each control element 334, 344, 354 can be routed through the dock, first entering through cavity C (including the pin receiving volume PRV and the control element receiving volume CRV), and then exiting the outlet portion or hole of the pump dock 310. The physical coupling or fixation of each pump 330, 340, 350 can be provided by the relative shape and / or volume of cavity C relative to the pin of the pump (for example, cavity C can be shaped and / or sized relative to each pin of each pump electrical connector 333, 343, 353 to provide an interference fit). In addition, or alternatively, such physical coupling or fixation can be provided by tension applied by each control element 334, 344, 354. By configuring the pump 340 to be physically secured to the pump dock 310 via the collective mating arrangement of the pump electrical connector 343 and the dock electrical connector 312a, the pump 340 may be physically secured to the pump dock 310 without any additional securing or retaining mechanisms.

[0208] Although in this embodiment, the pump dock 310 includes a particular number and arrangement of cavities, volumes, lumens, etc., in other embodiments, the dock may have any suitable number and arrangement of cavities, volumes, lumens, etc., for example, to ensure that the components housed therein have sufficient space to operate without any complications or interruptions. For example, while the pump dock 310 has a female electrical connector and the pumps 330, 340, 350 have corresponding male connectors, the pump dock 310 has a male electrical connector and the pumps 330, 340, 350 have corresponding female connectors.

[0209] The modular pump system 300 may also include a catheter 316 coupled to the pump dock 310 and configured to extend from the pump dock 310 to, for example, an extravascular location and / or outside the subject's body. The catheter 316 is also configured to define at least one lumen to accommodate a power connector 313, control elements 334, 344, 355, and / or optional control components 314, similar to those described with respect to the catheter 116.

[0210] In some cases, it may be desirable to fluidly seal one or more cavities of a dock prior to docking one or more pumps to the dock, for example, to limit or prevent blood from entering the one or more cavities. Figures 6A-6E , Fig. 7A -D and Fig. 8A -C illustrates a modular pump system 400 configured to provide such a fluid seal according to an embodiment. The form and / or function of the modular pump system 400 can be similar or identical to any modular pump system described herein (e.g., modular pump system 100, modular pump system 300, etc.). Therefore, portions of the modular pump system 400 are not described in more detail herein, but rather the focus will be on the portions of the modular pump system 400 that are configured to provide a fluid seal as described above.

[0211] First, Fig. 6E As shown in the perspective diagram in Fig. 8A-C, the modular pump system 400 includes three seals 450 (also referred to herein as "plugs"). Although there are three seals in this embodiment, in some embodiments, any suitable number of seals may be included, for example, depending on the number of pumps in the modular pump system and / or corresponding thereto. The seal 450 can have any shape, size, and can be formed of any material, suitable for insertion and deployment in the cavity C of the pump dock 410, and plug or seal the corresponding cavity C to limit and / or prevent fluid (e.g., blood) from entering the cavity. In some embodiments, for example, each seal 450 can be formed of silicon, thermoplastic elastomer, rubber, polytetrafluoroethylene, etc. Each seal 450 defines a lumen L across its length so that the control elements 434, 444, 454 can be routed through it. When the control elements 434, 444, 454 are deployed in the lumen L, the shape and size of the lumen L can be set to limit and / or prevent any fluid from entering or passing through the lumen L. For example, the diameter of lumen L can be slightly larger than control elements 434, 444, 454 so that control elements 434, 444, 454 can translate through lumen L. Additionally, in this manner, this arrangement can limit or prevent any undesirable twisting, kinking, etc. of control elements 434, 444, 454.

[0212] In this embodiment, each cavity C of the docking station electrical connectors 412a, 412b, 412c (also referred to herein as docking station electrical connectors) is shaped and sized to accommodate (i) a pump electrical connector 433, 443, 453 (also referred to herein as device electrical connectors) (e.g., their respective pins) from each pump 430, 440, 450 (similar to the modular pump system 300) and (ii) one of the seals 450. Figures 4A-4C and Figures 5A-5C As shown in FIG. 4 , the docking station electrical connectors 412 a , 412 b , 412 c are associated with or integrated with a pump receiving surface that is at least partially defined by a protrusion that projects distally in a direction opposite from the catheter 416 .

[0213] For simplicity, the following description will focus on a single pump (i.e., pump 430) and associated components; however, it should be appreciated that this description is equally applicable to the other pumps (i.e., pumps 440 and 450) and associated components of the modular pump system 400. In use, as Figures 8A-8C As shown in the sequence, the pump dock 410 can be delivered through the vascular system of the subject, and the seal 450 is inserted into the cavity C, and one end of the seal 450 terminates at the entrance of the cavity C to limit and / or prevent blood (and / or other fluids) from entering the cavity C, as shown in FIG. Fig. 8A Also, as shown, the control element 434 is routed through the lumen L of the seal 450.

[0214] When the operator is ready to dock the pump 430 with the pump dock 410, the operator can manipulate (e.g., push or pull) the control element 434 to advance the pump 430 into the cavity C, similar to that described in other embodiments herein. However, in this embodiment, the pump electrical connector 433 contacts the seal 450, thereby forcing and / or driving the seal 450 deeper into the cavity C, so that the seal 450 seals at or near the end of the cavity C and / or at or near the interface of the pin receiving volume PRV and the control element receiving volume CRV (also referred to herein as a control element channel guide), such as Figure 8C In this manner, cavity C can be kept free of blood (or substantially free of blood) (and / or other fluids) during delivery to pump dock 410 (via seal 450), during docking (combined via pump electrical connector 433 and seal 450), and after docking (via pump electrical connector 433).

[0215] Although modular pump system 400 is shown and described as having three seals (ie, one seal per pump and per dock cavity), in some embodiments, more than three seals may be incorporated. Figures 9A-9E , Figures 10A-10D and Figures 11A-11C A modular pump system 500 having six seals 550 is illustrated according to an embodiment. The modular pump system 500 can be similar or identical in form and / or function to the modular pump system 400, except that the modular pump system 500 includes additional seals 550, as described in further detail below. Therefore, portions of the modular pump system 500 are not described in further detail herein, and instead the focus is placed on portions of the modular pump system 500 that are configured to provide a fluid seal via the six seals 550.

[0216] In this embodiment, three seals 550 are each configured to couple to and be disposed around at least a portion of the pump electrical connectors 533, 543, 553, e.g. Fig. 9C , Fig.9D and Fig.9E. These three seals will be referred to herein as 550A. Seal 550A is open at both ends, with lumen L located therebetween to accommodate pump electrical connectors 533, 543, 553. The size and shape of seal 550A are designed to be mounted around pump electrical connectors 533, 543, 553 in a close fit (e.g., interference fit) manner, thereby providing a fluid seal therebetween when coupled. In addition, at least the distal portion of each seal 550A is configured to have a cross-sectional area larger than the cross-sectional area of ​​at least the entrance of cavity C, so that the distal portion of seal 550A does not fit into cavity C during docking, but abuts against the entrance of cavity C during docking to fluidly seal the entrance, as described in further detail below.

[0217] The remaining three seals 550 will be referred to herein as 550B, and their form and / or function may be the same or similar to seal 450. All seals 550 may be formed of any suitable material. In some embodiments, for example, seals 550 are formed of silicon.

[0218] For simplicity, the following description will focus on a single pump (i.e., pump 530) and associated components; however, it should be appreciated that this description is equally applicable to the other pumps (i.e., pumps 540 and 550) and associated components of the modular pump system 500. In use, as Figures 11A-11C As shown in the sequence, the pump dock 510 can be delivered through the vascular system of the subject, the seal 550B is inserted into the cavity C, and one end of the seal 550A terminates at the entrance of the cavity C to limit and / or prevent blood (and / or other fluids) from entering the cavity C, as shown in FIG. Fig.11A Also, as shown, according to an embodiment, the control element 534 is routed through the lumen L of the seal 550B.

[0219] Additionally, pump 530 may be delivered through the vasculature of a subject with seal 550A coupled to and disposed about pump electrical connector 533 (also referred to herein as device electrical connector), such as Fig.11A When the operator is ready to dock the pump 530 with the pump dock 510, the operator can manipulate (e.g., push or pull) the control element 534 to advance the pump 530 into the cavity C, similar to that described in other embodiments herein. However, in this embodiment, the pump electrical connector 533 contacts the seal 550B, thereby forcing and / or driving the seal 550B deeper into the cavity C, so that the seal 550B seals at or near one end of the cavity C and / or at or near the interface of the pin receiving volume PRV and the control element receiving volume CRV (also referred to herein as a control element channel guide), as shown in FIG. Fig. 11CIn addition, when the pump electrical connector 533 is docked near the entrance of cavity C, the seal 550A disposed around the pump electrical connector 533, and in particular the distal portion of the seal 550A, contacts both the pump receiving surface 511A and the portion of the pump docking station 510 that forms or defines the entrance of cavity C, thereby fluid-sealing cavity C, as shown in FIG. Fig. 11B With seal 550A thus sealing pump dock 510, the operator can continue to advance pump 530 into cavity C so that pump electrical connector 533 can be advanced distally relative to and through the lumen of seal 550B, thereby maintaining seal 550B in fluid-tight contact with the entrance to cavity C. In this way, pump electrical connector 533 can be inserted into cavity C for docking, and seal 550A can be pushed further into cavity C while maintaining a fluid seal at the entrance to cavity C via seal 550A.

[0220] like Figures 11A-11C As shown in , the docking station electrical connector is associated with or integrated with a pump receiving surface that is at least partially defined by a protrusion that projects distally in a direction opposite to the catheter.

[0221] Thus, cavity C can be maintained free of blood (or substantially free of blood) (and / or other fluids) during delivery to pump dock 510 (via seal 550A), during docking (combined via seal 550B and pump electrical connector 533), and after docking (combined via seal 550B and pump electrical connector 533).

[0222] While some embodiments described herein include pumps having a single prong to accommodate docking, in some cases a pump may have more than one prong. Figures 12A-12D , Figures 13A-13D and Figures 14A-14C Such a modular pump system 600 according to an embodiment is illustrated. The modular pump system 600 can be similar or identical in form and / or function to any modular pump system described herein, except that the modular pump system 600 includes pumps 630, 640, 650, each pump having two pins, a first pin being a physical connector 633A, 643A, 653A (also referred to as a pump physical connector or a device physical connector) to facilitate docking to the pump dock 610, and a second pin being a pump electrical connector 633, 643, 653 (also referred to as a device electrical connector) similar in form and function to other electrical connectors described herein (e.g., pump electrical connectors 333, 343, 353). Therefore, portions of the modular pump system 600 will not be described in detail herein.

[0223] For simplicity, the following description will focus on a single pump (i.e., pump 630) and its associated components; however, it should be appreciated that such description is equally applicable to the other pumps (i.e., pumps 640 and 650) and their associated components of the modular pump system 600. As shown, the pump dock 610 defines two cavities: a physical connector cavity Cp (also referred to herein as a docking station physical connector) and an electrical connector cavity Ce (also referred to herein as a docking station electrical connector), which is similar in form and function to the other electrical connectors described herein (e.g., docking station electrical connectors 312a, 312b, 312c).

[0224] The physical connector cavity Cp is configured to receive and secure to the physical connector 633A when the pump 630 is docked to the pump dock 610, similar to that described in other embodiments herein. The electrical connector cavity Ce is similarly configured to receive and secure to the electrical connector 633B when the pump 630 is docked to the pump dock 610. The electrical connector cavity Ce defines a receiving volume RV for the electrical connector 633B and its conductive segments or rings CR. Coupled to and extending from the electrical connector cavity Ce are electrical connectors EC (e.g., wires, cables, etc.) that are relatively spaced apart at a spacing similar to that of the conductive rings CR and are configured to establish electrical connections with their corresponding conductive rings CR, such as Fig. 13C As shown in . Each electrical connector EC is then routed toward and electrically coupled to a power connector (not shown), similar to the power connector 113 described above. Moreover, as shown, the pump 630 includes a control element 634 extending from the pump 630 between the physical connector 633A and the electrical connector 633B. In use, this arrangement can help limit or prevent undesired rotation of the pump 630 relative to its axis (e.g., its central axis). In addition, in some embodiments, the physical connector 633A and the electrical connector 633B can have dissimilar shapes, sizes, and / or materials. For example, the physical connector 633A can include a metal (such as a nickel-titanium alloy), and / or can be shaped and / or sized to have a relatively tighter and / or more secure fit within the physical connector cavity Cp.

[0225] In some embodiments, the pump may include a pump electrical connector having a prong with a rounded or other curved surface, rather than a pump having a prong and a conductive ring as described in various embodiments herein. This prong may have a conductive detent or protrusion extending therefrom that is configured to physically and electrically mate with an electrical receiver disposed within the docking station. Figures 15A-17CSuch a modular pump system 700 according to an embodiment is illustrated. The modular pump system 700 can be similar or identical in form and / or function to any modular pump system described herein, except that the modular pump system 700 includes pumps 730, 740, 750, each having a pump electrical connector 733, 743, 753 (also referred to herein as a device electrical connector), thereby defining a curved distal portion having three conductive protrusions CP (each protrusion being configured to a separate phase, similar to that described with respect to the conductive ring in various embodiments herein). Therefore, portions of the modular pump system 700 are not described in further detail herein.

[0226] For simplicity, the following description will focus on a single pump (i.e., pump 730) and associated components; however, it should be appreciated that such description is equally applicable to the other pumps (i.e., pumps 740 and 750) and associated components of the modular pump system 700. Figures 17A-17C As shown in , the pump dock 710 includes a docking station electrical connector 712a (also referred to herein as a docking station electrical connector), which has a cavity C and an electrical receiver ER, and the electrical receiver ER has three cup-shaped or curved shaped portions configured to receive and / or cooperate with the conductive protrusion CP. The cavity C may include a fluid flushing port (not shown) provided at the bottom thereof, which is used to evacuate the cavity C and the fluid contained in the receiving volume RV when the pump electrical connector is inserted into the cavity C and the receiving volume RV to establish an electrical connection. The conductive protrusion can have any suitable shape (e.g., convex, dome, etc.) to cooperate with the electrical receiver ER. In some embodiments, the conductive protrusion CP can allow a relatively larger force to be applied during docking to displace any undesirable fluid (e.g., blood) between each conductive protrusion CP and the electrical receiver ER, thereby improving the electrical connection therebetween. Similar to some embodiments described herein, the docking station electrical connector 712a and the pump electrical connector 733 can be jointly shaped and sized to form an interference fit when docked. While in this embodiment the pump dock 710 houses the control element 734 and the docking electrical connector 712a within the same lumen or volume, in some embodiments, the pump dock 710 may include any suitable different lumens, for example, the dock may include a first lumen for the control element 734 and a second different lumen for the docking electrical connector 712a (e.g., and its connection to the power connector 713).

[0227] Various embodiments described herein include modular pump systems having pumps to which control elements are attached and extend from the pumps to accommodate delivery and docking of those pumps. In some cases, it may be desirable to decouple the control elements from the pumps, for example, after delivery and docking of the pumps. Figures 18A-20CSuch a modular pump system 800 is illustrated according to an embodiment. The modular pump system 800 may be similar or identical in form and / or function to any modular pump system described herein. Therefore, portions of the modular pump system 800 will not be described in detail herein.

[0228] For simplicity, the following description will focus on a single pump (i.e., pump 830) and its associated components; however, it should be appreciated that such description is equally applicable to the other pumps (i.e., pumps 840 and 850) and associated components of the modular pump system 800. In this embodiment, the pump 830 is removably attachable to the control element 834, and more specifically, the pump 830 defines a threaded recess R that is configured to be threadably coupled to a threaded coupler of the control element 834, such as Fig. 20A . A threaded recess R is located at the distal end of an electrical connector 833 (also referred to herein as a device electrical connector) of the pump 830. Although a threaded coupling is used in this embodiment, it should be noted that in some embodiments, any suitable coupling mechanism and / or arrangement may be used so that an operator can manipulate (e.g., pull, push, twist, etc.) a control element (e.g., from outside the subject) to decouple the control element from the pump. For example, the pump 830 may be removably attachable to the control element 834 via a wire routed in the control element 834 that forms a loop or lasso (i.e., like a loop breaker) for removably attaching the pump 830.

[0229] In use, such as Figures 20A-20C As shown in the sequence, pump 830 is coupled to control element 834. Similar to the previous embodiments described herein, pump 830 can be delivered through the vasculature of a subject, and an operator can manipulate (e.g., push or pull) control element 834 to advance pump 830 into cavity C defined by pump dock 810. Once docked, as shown in FIG. Fig. 20B As shown in , the operator can manipulate (e.g., twist, rotate, etc.) the control element 834 to decouple and separate the control element 834 from the threaded recess R and the pump 830, and then the operator can remove the control element 834 from the pump dock 810 and, if desired, from the subject's vascular system or body.

[0230] In some cases, it may be desirable to route a removably attachable control element through a catheter such that the control element is stiffer / harder than the catheter and provides sufficient stiffness and / or tactile feedback to the operator to manipulate the pump within the subject, but can be decoupled and removed from the subject after docking, leaving a relatively more flexible catheter coupled to the pump. Figures 21A-22C Such a modular pump system 900 is illustrated according to an embodiment.

[0231] Modular pump system 900 may be similar or identical in form and / or function to any modular pump system described herein (eg, modular pump system 800). Accordingly, portions of modular pump system 900 will not be described in detail herein.

[0232] For simplicity, the following description will focus on a single pump (i.e., pump 930) and associated components; however, it should be appreciated that such description may equally apply to other pumps (i.e., pumps 940 and 950) and associated components of modular pump system 900. Similar to modular pump system 800, in this embodiment, control element 934 is configured to be separate from pump 930, but, here, when the pump is docked and deployed at its implantation site, control element 934 is routed through the lumen of catheter Ca, which is attached to pump 930 and configured to extend from pump 930 through the subject's vasculature and outside the subject's body. In this manner, an operator can manipulate control element 934 while it is coupled to pump 930 in order to dock pump 930 to pump dock 910, and then the operator can decouple and remove control element 934 from pump 930 (e.g., from the subject's vasculature and / or body), thereby coupling catheter Ca to and extending from the docked pump 830. Thus, the relatively more rigid / harder control element 934 can be removed from the subject, while the relatively more flexible catheter can remain in the subject and provide a channel for introducing additional components and / or fluids to the implantation site. This flexibility is suitable for conforming to the subject's vasculature.

[0233] As discussed with respect to modular pump system 100, in some cases, it may be desirable to flush the modular pump system to limit and / or prevent blood from entering the pump motor. In some cases, the heat generated by the modular pump system can cook or otherwise cause the blood to coagulate or coagulate, for example, to a jelly or gelatin consistency (i.e., causing the formation of a blood clot), which can block or otherwise interrupt motor functionality. In some embodiments, the pump has a fully enclosed motor and has a magnetic coupling between the motor and the impeller, and such heated blood can enter between these magnetically coupled parts, so in those cases, it would be beneficial to deliver fluid to flush the pump and / or motor, and, for example, flow out at the interface of the impeller and the pump housing. Any suitable fluid can be used, such as, for example, glucose (e.g., 5%, etc.) or any other biocompatible fluid. Figures 23A-25D Such a modular pump system 1000 is illustrated according to an embodiment.

[0234] Modular pump system 1000 can be similar or identical in form and / or function to any modular pump system described herein (eg, modular pump system 900). Accordingly, portions of modular pump system 1000 will not be described in detail herein.

[0235] For simplicity, the following description will focus on a single pump (i.e., pump 1030) and associated components; however, it will be appreciated that such description may equally apply to the other pumps (i.e., pumps 1040 and 1050) and associated components of modular pump system 1000. Similar to modular pump system 900, in this embodiment, conduit Ca is coupled to and extends from pump 1030 and is routed through pump dock 1010 as described in prior embodiments. Conduit Ca defines a lumen through which a fluid F may be delivered from outside the subject's body and delivered to pump 1030. Fluid F may be delivered from a reservoir R deployed outside the subject's body, for example, Fig.25B and Fig.25D As shown in . In this embodiment, the catheter Ca can be used as a catheter for conveying fluids, and can also be used as a control element 1034 for the operator to manipulate the conveying, docking and / or undocking pump 1030, as described in further detail herein in conjunction with other embodiments. That is, in some embodiments, similar to what is described about the modular pump system 900, the catheter can define a lumen through which a relatively more rigid (and separable) control element and a catheter for fluid can be routed. In such embodiments, for example, a control element can be routed through a catheter and removably attached to a pump to facilitate docking of the pump, and then the control element can be separated from the pump and removed through the catheter lumen, so that the catheter is coupled to the pump. Then, as described above, the operator can flush by conveying fluid F through the catheter lumen. In yet further embodiments, the catheter can have multiple lumens, such as a first lumen configured to receive a control element, and a second independent lumen configured to receive a fluid from a fluid flushing device.

[0236] Consistent with the desire to minimize the footprint of the modular pump system within the subject, including minimizing any components extending from the implanted pump and dock through the subject's vasculature and / or outside the subject's body (e.g., power transmission cables, wires, etc.), in some embodiments, the modular pump system can transmit power wirelessly. For context, such wireless energy transfer can include features similar to those described in U.S. Patent No. 10,143,788, entitled "Transcutaneous Energy Transfer Systems," which is incorporated herein by reference in its entirety. Fig.26A-D illustrates such a modular pump system 1100 according to an embodiment, including a power connector 1113, which is or has a coil 1113c, which (ii) is coupled to an anchor 1115 of a pump dock 1110, and (ii) is configured to receive inductive power from a source located outside the vasculature and / or body of a subject. The modular pump system 1100 can be similar or identical in form and / or function to any modular pump system described herein. Therefore, portions of the modular pump system 1100 are not described in detail herein.

[0237] like Fig.26B and Fig.26C As shown in , the pump dock 1110 includes an anchor 1115. Coupled to the outer surface of the anchor 1115 and extending therefrom is a coil 111c (also referred to herein as a "receiver coil") that is made of wire (and / or any other suitable component) in a disc shape. The modular pump system 1100 also includes an energy storage component (e.g., a battery) (not shown) that is operably coupled to the coil 1111c and is configured to store energy and / or transfer energy from the coil 1111c to the pumps 1130, 1140, 1150. In use, a transmitter (e.g., a transmitter coil) (not shown) can be proximate to the implanted coil 111c to transfer power from the transmitter coil to the receiver coil 111c to thereby power the implanted components (pumps 1130, 1140, 1150) of the modular pump system 1100. It should be noted that the coil 1111c can accommodate expansion and compression of the anchor 1115, for example, during implantation and delivery, respectively.

[0238] The receiver coil may be of any suitable shape and size. Figures 27A-28C A modular pump system 1200 is illustrated having a coil 1211c formed of wire (and / or any other suitable component) disposed circumferentially about an anchor 1215, according to an embodiment. In this embodiment, for example, the coil 1211c can accommodate relatively more windings or surface area relative to the modular pump system 1100. Additionally, while in this embodiment the coil 1211c is maintained between the distal and proximal ends of the anchor 1215, in some embodiments, the coil 1211c can extend beyond the distal and / or proximal ends of the anchor 1215. Moreover, in some embodiments, the coil can have other shapes and / or configurations, for example, it can have an angled shape, and / or have wires that are more spaced apart to accommodate expansion and compression of the anchor. Additionally, as Fig.28B As best shown in FIG. 1 , pump dock 1210 includes a battery B electrically coupled to coil 1211 .

[0239] In some cases, it may be desirable to push each pump to deliver each pump through the subject's vasculature and dock to a dock at the implantation site. Figures 29A-29D Such a pump system 1300 is illustrated according to an embodiment.

[0240] The modular pump system 1300 can be similar or identical in form and / or function to any modular pump system described herein. Therefore, portions of the modular pump system 1300 will not be described in detail herein.

[0241] For simplicity, the following description will focus on a single pump (i.e., pump 1330) and associated components; however, it should be appreciated that such description may also apply to the other pumps (i.e., pumps 1340 and 1350) and associated components of modular pump system 1300.

[0242] In this embodiment, pump 1330 is configured to fit and be delivered to an implantation site within the lumen of catheter Ca. Figures 29A-29C 1300, but the modular pump system 1300 includes a control element, each of which is configured to be removably attached to the pump so that the control element can be released from the pump when in use, similar to that described in several embodiments herein. In this embodiment, the control element is rigid enough so that the operator can push the proximal portion of the control element to advance the distal end of the control element (and the components coupled there, such as pumps) in the subject's vascular system, and each pump coupled to each control element can engage with and dock to the pump dock 1310. In some embodiments, for example, each control element can be a push rod. Alternatively, a relatively rigid cable or a relatively rigid line can be routed in the catheter control element of the pump to provide enough hardness to the control element to push it. For example, when the control element (not shown) is removably attached to the pump 1330, the operator can push the control element and / or the catheter Ca to advance the pump 1330 (together with the catheter Ca) in the subject's vascular system dock pump 1330, and the pump dock 1310 is located at the implantation site. In this embodiment, the pump electrical connector 1333 (also referred to herein as the device electrical connector) protrudes from the outer surface of the pump 1330 spaced apart from the pins of the pump 1330, as shown in the figure, and is configured to correspond with the docking electrical connector 1312a (also referred to herein as the docking electrical connector) of the pump dock 1310, which in this embodiment is configured to receive and be fixed to the recess R of the pump electrical connector 1333, thereby providing both a physical fixing function and an electrical connection to transmit energy from the pump dock 1310 to the pump 1330, similar to what is described in conjunction with various embodiments herein. Fig.29D A close-up detailed view of the docking electrical connector 1312a and the pump electrical connector 1343 engaged with the docking electrical connector 1312b is illustrated.

[0243] In addition, if Figures 29A-29C As shown in FIG. 1 , anchors 1315 define cells through which pumps (eg, pumps 1330 and 1340 ) may be advanced and deployed when docked to pump dock 1310 .
