Description

Cross Reference to Related Applications

[0001] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application No. 63 / 517,640, filed August 4, 2023, which is incorporated by reference herein in its entirety. TECHNICAL FIELD

[0002] The present invention relates generally to medical devices, systems, and related methods for wetting a medical instrument. More particularly, at least some embodiments of the present invention relate to devices, systems, and related methods for lubricating a medical instrument prior to insertion into a body cavity of a subject. BACKGROUND

[0003] Medical instruments / devices are often inserted into a subject to perform a therapeutic and / or diagnostic procedure in the subject. One example of such a device is a catheter that is introduced into the body to access various portions of the subject’s anatomy and / or to deliver a therapy to a target tissue. The catheter is inserted into the subject through an opening (e.g., a natural opening or an incision) and is delivered, for example, through a body lumen to a target tissue site within the body. In one example, the catheter can be inserted directly into the subject’s mouth and advanced through the subject’s esophagus to a target site. In another example, the catheter can be inserted into the subject via a secondary medical device, such as, for example, a device having a working channel (e.g., a scope, such as an endoscope).

[0004] One or more portions of a catheter or other medical instrument / device can be wetted or lubricated prior to insertion of the catheter into the subject. Wetting one or more portions of a catheter or other medical device / instrument prior to insertion of the catheter into the subject can help to improve the comfort of the subject during the procedure. For example, lubricating a catheter can help to reduce friction between the catheter or other medical device / instrument and the subject and / or between the catheter and a secondary medical device. Accordingly, there is a need for medical systems, devices, and related methods for wetting or lubricating a medical instrument during a medical procedure. SUMMARY

[0005] Examples of the present invention relate to systems, devices, and methods, among other things, for performing one or more medical procedures with a medical device. In particular, the present invention includes medical systems, devices, and methods for wetting a medical instrument. Each of the examples disclosed herein can include one or more of the features described in connection with any of the other disclosed examples.

[0006] According to one aspect, a medical system can include a fluid source, a fluid reservoir, and a valve. The valve can be coupled to the fluid source and the fluid reservoir so as to allow fluid flow between the fluid source and the fluid reservoir. The valve can include a first opening configured to receive a medical instrument. Upon insertion of the medical instrument into the first opening of the first valve, the medical instrument can be lubricated by fluid from the fluid source.

[0007] In some aspects, the medical system can further include an adapter. A first end of the adapter can be coupled to the first opening of the valve. A second end of the adapter can include an opening configured to receive the medical instrument. The adapter can include a gate configured to prevent fluid flow from the first end of the adapter to the second end of the adapter. The gate can include a first end and a second end. The first end can be fixed to a wall of the adapter. The second end of the gate can be free.

[0008] In some aspects, in the first configuration, the second end of the gate can abut a wall of the cavity of the adapter. Upon insertion of the medical instrument into the adapter and through the gate, the gate can transition to a second configuration. In the second configuration, the second end of the gate can abut a surface of the medical instrument. In the second configuration, the gate can be configured to prevent fluid flow from the first end of the adapter to the second end of the adapter. In some aspects, the second end of the gate can be located between the first end of the adapter and the first end of the gate.

[0009] In some aspects, the adapter can include a channel extending through a wall of the adapter. The channel can extend along at least a portion of a length of the adapter. In some aspects, the adapter can be integrally formed with the valve.

[0010] In some aspects, the valve can further include a first arm, a second arm, a third arm, and a fourth arm. The first arm can be coupled to the fluid source. The second arm can be coupled to the fluid reservoir. The third arm can include a first opening configured to receive a medical instrument. The fourth arm can include a second opening. Each of the first arm, the second arm, the third arm, and the fourth arm can be fluidly connected.

[0011] In some aspects, a longitudinal axis of the third arm can be angled in a first direction relative to a longitudinal axis of the first arm. A longitudinal axis of the fourth arm can be angled in a second direction relative to the longitudinal axis of the first arm. The longitudinal axis of the first arm and the longitudinal axis of the fourth arm can be parallel or coaxial. The longitudinal axis of the second arm and the longitudinal axis of the third arm can be parallel or coaxial.

[0012] In some aspects, the first direction of the first arm can be opposite the second direction of the fourth arm.

[0013] In some aspects, the fluid reservoir can be fluidly coupled to a medical device.

[0014] In some aspects, a conduit can be coupled to the second opening of the fourth arm. The conduit can include a first branch, a second branch, and a third branch. The first branch can be coupled to the fourth arm. The second branch can include an opening configured to receive a second medical instrument. The third branch can be coupled to an opening of a medical device having a working channel.

[0015] According to other aspects, a medical system can include a fluid container and an immersion container. The immersion container can be configured to receive at least a portion of a medical instrument. The immersion container can include a first opening in a bottom or a side of the immersion container. The immersion container can include a second opening configured to receive the medical instrument. The fluid container can be fluidly coupled to the immersion container via the first opening. In some aspects, the immersion container can be movable relative to the fluid container.

[0016] In some aspects, the medical system can further include a stop. The stop can be configured to prevent fluid flow to the immersion container in a first configuration. The stop can be configured to allow fluid flow to the immersion container in a second configuration.

[0017] In some aspects, the medical system can further include a coupler secured to the immersion container. The coupler can be configured to removably couple the immersion container to the fluid container.

[0018] In some aspects, a wall of the fluid container can define a wall of the immersion container.

[0019] According to other aspects, a medical device can include a bridge, a base, an arm, and a gap between the base and the arm. The base can extend laterally from the bridge in a first direction. The arm can extend laterally from the bridge in the first direction. The arm can include a nozzle configured to deliver fluid to the gap. The fluid can be applied to a surface of a medical instrument as the medical instrument is inserted through the gap.

[0020] In some aspects, the medical device includes a controller, where the controller is configured to control delivery of the fluid.

[0021] Any of the examples described herein can have any of these features in any combination. BRIEF DESCRIPTION OF DRAWINGS

[0033] Reference will now be made in detail to aspects of the present application, examples of which are illustrated in the accompanying drawings. Wherever possible, the same or like reference numbers will be used throughout the drawings to refer to the same or like parts. The term "distal" refers to the portion that is farthest from the user when the device is introduced into the body of a subject (e.g., a patient). Conversely, the term "proximal" refers to the portion that is closest to the user when the device is placed in the body of a subject. In the various figures, the proximal and distal directions are marked with arrows labeled "P" and "D," respectively. ​​​​​​​​​

[0034] The foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the features, as claimed. As used herein, the terms "comprises," "comprising," "includes," "including," "has," "having," "contains" or "containing," or other variations thereof, are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. In this disclosure, relative terms such as, for example, "about," "substantially," "approximately," and "near" are used to indicate a possible variation of ±10% of the stated value or property. Additionally, terms denoting component / surface geometry encompass both exact and approximate shapes.

[0035] Medical devices / instruments, such as, for example, scopes, catheters, guide wires, baskets, forceps, or any other medical device, are often inserted into a subject to perform a therapeutic and / or diagnostic procedure within the subject. Herein, the phrases "medical device" and "medical instrument" are used interchangeably. The medical device can be inserted directly into the subject (e.g., via an orifice in the subject) and / or by another medical device, for example, a medical device having a working channel, such as an endoscope or other type of scope. Inserting the medical device into the subject and / or into another medical device can be difficult due to frictional forces between the medical devices and / or between the medical device and the subject's tissue. These frictional forces can result in subject discomfort, subject injury, prolonged procedure time, and other adverse outcomes. To overcome these frictional forces between the medical devices and / or between the medical device and the subject, the surface of the medical device is often lubricated.

[0036] Currently, to wet or lubricate a medical device, a portion (e.g., a distal portion) of the medical device is immersed in an open container filled with water, saline, or other lubricant. The container can be placed on, for example, a tower or flat surface (e.g., counter, table, etc.) within an operating room. The container can take up valuable space within the operating room and having an open container within the operating room increases the likelihood that water or lubricant will spill onto the floor or another surface. Spills can be hazardous to electrical equipment and / or personnel in the operating room.

[0037] The present disclosure relates to medical systems, devices, and related methods for wetting or lubricating surfaces of medical devices / instruments. Wetting one or more portions of a medical device can help improve the comfort of a subject during a procedure and achieve other benefits prior to insertion of the medical device into a subject or into a working channel of another medical device. For example, lubricating a device can help reduce friction between the device and a subject and / or between the device and a secondary medical device. Some of the embodiments described herein utilize a fluid source (e.g., an irrigation / lens cleaning source) used for other aspects of a medical procedure as a fluid source for lubricating a medical device. Aspects herein can provide a lubricating fluid source without the need for an open container.

[0038] The present disclosure is described with reference to exemplary medical systems for lubricating or wetting medical instruments. This can provide improved medical device / instrument functionality and / or help medical professionals perform medical procedures. However, it should be noted that reference to any particular device and / or any particular procedure is provided for convenience only and is not intended to limit the present disclosure. One of ordinary skill in the art will recognize the deep conceptual underpinnings of the disclosed systems, devices, and methods of application can be used in any suitable procedure, medical or otherwise. The devices, components, and systems described herein can be used in conjunction with other types of medical devices. The present disclosure can be understood with reference to the following description and drawings, wherein like elements are referred to with like reference numerals.

[0039] Reference is made to Figure 1 FIG. 1 shows a medical system 10 in accordance with one exemplary embodiment. The medical system 10 can include a medical device 20, a wetting system 40, and a processing unit 5. The medical device 20 can include a handle 22 and an insertion portion 24 (e.g., a shaft or catheter). The insertion portion 24 can be connected to a distal portion of the handle 22. The insertion portion 24 can terminate distally in a distal tip 26. An umbilical 7 can extend from a proximal portion of the handle 22 (or another portion of the handle 22).

[0040] The umbilical 7 can be removably coupled (e.g., directly or indirectly) to the processing unit 5. The processing unit 5 can be configured to process information (e.g., sensor data, imaging data, light data, etc.) received from the medical device 20. In some aspects, the processing unit 5 can be a controller associated with the medical device 20. The umbilical 7 can include one or more electrical and / or optical cables for coupling to the processing unit 5 via, for example, a removable connector. Although not shown, the processing unit 5 can include a visual output (e.g., an internal monitor or screen), or the processing unit 5 can be coupled to a visual output (e.g., an external or separate monitor or screen). Although not shown, the umbilical 7 can additionally or alternatively include one or more lumens for supplying gas or liquid to the handle 22 and / or the insertion portion 24.

[0041] Handle 22 can include a first actuator 28A and / or a second actuator 28B. First actuator 28A and / or second actuator 28B can include, for example, a rotatable knob that rotates to push / pull one or more elements that extend through insertion portion 24 and are connected to distal portion 30 of insertion portion 24. For example, first actuator 28A and / or second actuator 28B can be configured to rotate about its axis to push / pull an actuation element (e.g., a wire, not shown) that extends within one or more lumens of insertion portion 24. Rotation of first actuator 28A and / or second actuator 28B can cause insertion portion 24 and / or distal portion 30 to bend, for example, via a hinged joint (not shown). Additionally or alternatively, handle 22 can include additional actuators (e.g., buttons, knobs, levers, locks, etc.) to, for example, limit movement of first actuator 28A and / or second actuator 28B, close or open forceps, rotate an end effector about a longitudinal axis, raise or lower a lifter, capture images, and / or provide other functionality to an end effector and / or distal portion 30.

[0042] Handle 22 can also include a first valve 32A and a second valve 32B. Although two valves (i.e., first valve 32A and second valve 32B) are shown, handle 22 can include additional valves (e.g., a third valve, a fourth valve, etc.) or fewer valves (e.g., no valves or only first valve 32A). In some embodiments, first valve 32A can be configured to control the supply of air and / or water to distal portion 30. Second valve 32B can be configured to control the application of suction to distal portion 30. Additional valves can be used, for example, to control the application of one or more drugs, medicaments, materials, etc. to distal portion 30.

[0043] Handle 22 can also include a proximal port / opening 34 that can be fluidly connected to one or more lumens (e.g., a working channel) of insertion portion 24. For example, a medical instrument (not shown in FIG. 2) can be inserted into proximal opening 34 and can extend through the one or more lumens to distal portion 30. The lumens can have one or more distal openings 36 at distal tip 26, which can be the distal-most end of distal portion 30. Distal openings 36 can be fluidly coupled to proximal opening 34. In this way, a medical instrument inserted into proximal opening 34 can extend distally through and from distal openings 36. Additionally or alternatively, one or more materials (e.g., a liquid, a gel, a gas, a patch, a powder, etc.) can be supplied to a target site via distal openings 36. Additionally or alternatively, suction can be supplied via proximal opening 34, for example, to remove debris from a target site via distal openings 36. Figure 1

[0044] ​Although not shown, the distal portion 30 can include one or more articulating joints. The distal tip 26 can include one or more end effectors and / or openings for suction, irrigation, insufflation, auxiliary devices, etc. The distal portion 30 can also include one or more devices 38. The devices 38 can include one or more visualization devices (e.g., cameras, image sensors, lenses, etc.), one or more illumination devices (e.g., LEDs, optical fibers, etc.), one or more therapeutic devices (e.g., laser fibers, lifters, etc.), and / or one or more other devices to image, view, or otherwise treat a treatment site by other means.

[0045] The wetting system 40 can be configured to wet or lubricate a medical instrument prior to the medical instrument being inserted into the medical device 20, e.g., into the proximal opening 34 of the handle 22 of the medical device 20 (not shown in Figure 1 ). For example, the medical instrument can be inserted into and / or through the wetting system 40 and lubricated by the wetting system 40. Once the medical instrument is lubricated by the wetting system 40, the medical instrument can be inserted into the proximal opening 34 and extend through one or more lumens to the distal portion 30 of the medical device 20.

[0046] In some aspects, the wetting system 40 can be fluidly coupled to one or more aspects of the medical device 20. For example, the wetting system 40 can be fluidly coupled to the proximal opening 34 via an optional conduit 42 extending between the wetting system 40 and the medical device 20. For example, a first end of the conduit 42 can be fixedly or removably coupled to the wetting system 40. A second end of the conduit 42 can be fixedly or removably coupled to the proximal opening 34 and / or one or more lumens of the medical device 20. In this manner, a medical instrument can be inserted into the proximal opening 34 of the handle 22 of the medical device 20 via the wetting system 40 and the conduit 42. For example, the medical instrument can first be inserted into the wetting system 40, where the medical instrument is lubricated. The lubricated medical instrument can then extend through the conduit 42 and subsequently into the proximal opening 34 of the medical device 20.

[0047] Additionally or alternatively, in some aspects, the wetting system 40 can be fluidly coupled to the umbilical 7 and / or the processing unit 5 of the medical device 20. For example, the conduit 42 and / or another conduit 44 (shown in dashed lines) can fluidly couple the wetting system 40 to one or more portions of the umbilical 7 and / or the processing unit 5. The wetting system 40 can be used in conjunction with the medical device 20 or as a standalone system. For example, the wetting system 40 and embodiments discussed herein can be used in conjunction with any medical system or device for which a medical device is to be wetted or lubricated. In some configurations, the wetting system 40 can be used with an external fluid source. For example, the external fluid source can be a fluid source for irrigation / lens cleaning used with or in conjunction with the medical device 20.

[0048] Figure 2 A front view of an example configuration of the wetness system 140 during use is shown. The wetness system 140 includes a fluid container 144, a reservoir 146, and a valve 148. The valve 148 can be configured to allow fluid communication between the fluid container 144 and the reservoir 146. For example, fluid from the fluid container 144 can flow through the valve 148 and into the reservoir 146. Figures 3A-3C More details of the valve 148 are depicted.

[0049] The fluid container 144 can be any flexible or rigid container configured to contain fluid. For example, the fluid container 144 can be a water, saline, or intravenous (IV) bag or bottle. The fluid container 144 can contain fluid (e.g., water, saline, or another fluid). The fluid container 144 can include one or more ports. For example, the fluid container 144 can include a first port 144A and / or a second port 144B. One or both of the first port 144A and the second port 144B can be composed of a self-sealing rubber or silicone material. For example, the first port 144A and / or the second port 144B can be punctured one or more times, for example, to allow fluid to flow into or out of the fluid container 144.

[0050] In some examples, the first port 144A can be configured to allow a user to inject additional fluid into the fluid container 144 and / or to withdraw fluid from the fluid container 144. The user can use, for example, a needle or an alternative injection device to inject fluid into or withdraw fluid from the fluid container 144. In some examples, the user can inject a medicament, such as a drug or another fluid, into the fluid container 144. The medicament can be any medicament in liquid form, for example, a painkiller, a coagulant, an anti-coagulant, or any other medicament commonly used in endoscopic procedures. The medicament can be combined with another fluid already in the fluid container 144 or can be the only fluid in the fluid container 144.

[0051] The second port 144B can be configured to allow fluid to flow out of the fluid container 144. For example, the second port 144B can be configured to be punctured by a spike 150 of the valve 148. The spike 150 can be configured to facilitate fluid connection between the fluid container 144 and the valve 148. The spike 150 can be conical in shape with a sharp tip for puncturing the second port 144B of the fluid container 144. In some examples, the spike 150 can resemble a needle in shape. The spike 150 can have an opening 150A at its tip that can provide access to one or more cavities of the valve 148.

[0052] Valve 148 includes a first arm 148A, a second arm 148B, a third arm 148C, and a fourth arm 148D. First arm 148A, second arm 148B, third arm 148C, and fourth arm 148D can be configured to be oriented in a similar manner to an "X" or cross. In some examples, one of the arms can be omitted (e.g., second arm 148B), such that valve 148 has a "Y" shape. As shown in FIGS. 1 and 2, first arm 148A, second arm 148B, third arm 148C, and fourth arm 148D can each have a respective lumen extending longitudinally therethrough. For example, first arm 148A has a first lumen 152A, second arm 148B has a second lumen 152B, third arm 148C has a third lumen 152C, and fourth arm 148D has a fourth lumen 152D. The lumens 152A, 152B, 152C, 152D of each respective arm 148A, 148B, 148C, 148D can be in fluid communication with one another. For example, lumens 152A, 152B, 152C, 152D can intersect at a junction 154 of valve 148. For example, a central longitudinal axis of first arm 148A can be substantially parallel to or coaxial with a central longitudinal axis of fourth arm 148D. A central longitudinal axis of second arm 148B can be substantially parallel to or coaxial with a central longitudinal axis of third arm 148C. Figure 3B and Figure 3C As shown in FIGS. 1 and 2, first arm 148A, second arm 148B, third arm 148C, and fourth arm 148D can each have a respective lumen extending longitudinally therethrough. For example, first arm 148A has a first lumen 152A, second arm 148B has a second lumen 152B, third arm 148C has a third lumen 152C, and fourth arm 148D has a fourth lumen 152D. The lumens 152A, 152B, 152C, 152D of each respective arm 148A, 148B, 148C, 148D can be in fluid communication with one another. For example, lumens 152A, 152B, 152C, 152D can intersect at a junction 154 of valve 148. For example, a central longitudinal axis of first arm 148A can be substantially parallel to or coaxial with a central longitudinal axis of fourth arm 148D. A central longitudinal axis of second arm 148B can be substantially parallel to or coaxial with a central longitudinal axis of third arm 148C.

[0053] A central longitudinal axis of first arm 148A can extend substantially in an upward direction. A proximal end of first arm 148A can include a spike 150. First arm 148A can also include a flange 156. Flange 156 can extend radially outward distally of spike 150. Flange 156 can be configured to, for example, prevent over-insertion of spike 150 into fluid container 144.

[0054] Fourth arm 148D can extend substantially in a downward direction. In examples, fourth arm 148D can be fluidly coupled to reservoir 146 via a first connector 158. First connector 158 can be any connector commonly used in the art to fluidly connect two components. In examples, first connector 158 can contact a surface of fourth arm 148D to couple fourth arm 148D to reservoir 146. First connector can be coupled to a first port 146A of reservoir 146.

[0055] Reservoir 146 can be any flexible or rigid container configured to contain a fluid. For example, reservoir 146 can be a bag or a bottle. Fluid can flow from fluid container 144, through lumens 152A and 152D of respective arms 148A and 148D, and into reservoir 146.

[0056] The second arm 148B can extend away from the first arm 148A in a first lateral direction. The third arm 148C can extend away from the first arm 148A in a second lateral direction. The second lateral direction can be opposite the first lateral direction. In this way, the second arm 148B and the third arm 148C can be angled relative to the first arm 148A. As Figure 2 illustrated, the angle between the second arm 148B and the third arm 148C can be transverse to the first arm 148A, but not perpendicular to the first arm 148A. Alternatively, the second arm 148B and the third arm 148C can each be perpendicular to the first arm 148A. The second arm 148B and the third arm 148C can have the same or different angles relative to the first arm 148A. In some examples, the opening 160 of the second arm 148B can be oriented such that the opening 160 of the second arm 148B faces in a distal direction. The opening 162 (labeled in Figures 3B-3C ) of the third arm 148C can be oriented such that the opening 162 of the third arm 148C faces in a proximal direction. In some examples, the opening 160 of the second arm 148B can face in an opposite direction relative to the opening 162 of the third arm 148C.

[0057] As Figures 3A-3C illustrated, the valve adapter 164 can be coupled to the third arm 148C of the valve 148. Although Figure 2 the valve adapter 164 is not depicted in Figure 2 , it should be understood that Figure 3A the system 140 can also include the valve adapter 164. Figure 3B is a front view of the valve 148 and the valve adapter 164. Figure 3C and Figure 3B are cross-sectional views of the valve 148 and the valve adapter 164 in a first configuration Figure 3C and a second configuration . The valve adapter 164 can be fixedly or removably coupled to the third arm 148C of the valve 148. In some examples, the valve adapter 164 can be composed of one or more flexible, stretchable, and / or semi-rigid materials to allow for attachment to the valve 148. For example, the valve adapter 164 can be coupled to the valve 148 via a friction fit, a snap fit, a press fit, or the like. Additionally or alternatively, the valve adapter 164 can be coupled to the valve 148 via one or more adhesives and / or mechanical fasteners (e.g., screws, rivets, set screws, or the like). The valve adapter 164 can include a combination of materials (e.g., some rigid materials and some flexible materials), or in some aspects can be made entirely of rigid materials. In other examples, the valve adapter 164 can be integrally formed with the valve 148.

[0058] Figure 3B and Figure 3CAs shown, the valve adapter 164 can be coupled to the third arm 148C such that the cavity 166 of the valve adapter 164 is in fluid communication with the cavity 152C of the third arm 148C extending through the valve 148. For example, the third arm 148C can be inserted into the cavity 166 of the valve adapter 164, and the cavity 166 of the valve adapter 164 can have walls shaped to receive and mate with the third arm 148C. The cavity 166 can be open on its longitudinal end. The third arm 148C can be inserted into a first opening 168 on a first end 164A of the valve adapter 164. A second opening 170 can be on a second end 164B (opposite the first end 164A) of the valve adapter 164.

[0059] The channel 172 can extend through the arm 174 of the valve adapter 164 to the cavity 166 such that a side of the cavity 166 is open. Thus, the channel 172 can provide a side opening to the cavity 166 of the valve adapter 164. The channel 172 can extend longitudinally along the valve adapter 164 along a portion of its length. For example, the channel 172 can extend from the second opening 170 on the second end 164B, but can not extend to the first opening 168 on the first end 164A. The channel 172 can facilitate insertion of the instrument 120 (discussed in further detail below) into the cavity 166, and thus into the cavity 152C of the third arm 148C. For example, the medical instrument 120 can be inserted into the cavity 166 of the valve adapter 164 via the channel 172 and / or via the second opening 170.

[0060] Referring to Figure 3B and Figure 3C , the valve adapter 164 can include a gate 176. The gate 176 can be between the opening 162 of the third arm 148C and the second opening 170 of the valve adapter 164 when the third arm 148C is inserted into the cavity 166. In the first configuration (the medical instrument 120 is not inserted beyond the gate 176), as shown, the gate 176 can be configured to prevent fluid flow in the direction from the first opening 162 of the third arm 148C to the second opening 170 of the adapter 164. For example, as shown by the curved arrow in the cavity 152C of the third arm 148C, Figure 3B the fluid flow can be stopped and / or reversed by the gate 176. Figure 3B

[0061] The gate 176 can be composed of a flexible material. For example, the gate 176 can be rubber, silicone, and / or a flexible plastic configured to seal or prevent fluid flow within the valve adapter 164. In some examples, in the first configuration, the gate 176 can extend the entire width of the cavity 166 of the valve adapter 164. As shown, Figure 3B and Figure 3C ​As shown, the gate 176 can have a first end 176A coupled to a wall of the valve adapter 164. The gate 176 can have a second free end 176B (e.g., not coupled to a wall of the adapter 164 or another element). In the first configuration, the free end 176B can contact or abut a wall of the adapter 164. The wall contacted or abutted by the free end 176B can be, for example, opposite the wall to which the first end 176A is fixed. The first end 176A can be closer to the second opening 170 than the second end 176B. The second end 176B can span a diameter / width of the cavity 166 and extend away from the second opening 170 and toward the first opening 162 of the cavity 166. In alternative aspects, the gate 176 can be a septum, a one-way fluid valve, a diaphragm, or another type of structure. The gate 176 can be, for example, an auto-seal valve.

[0062] In Figure 3C As shown in the second configuration, the medical instrument 120 can be inserted into the cavity 166 of the valve adapter 164 via the second opening 170 and / or the passage 172. When the medical instrument 120 is inserted into the cavity 166 of the valve adapter 164, the gate 176 can flex or deform to accommodate passage of the medical instrument 120. The gate 176 can open only to the extent that the medical instrument 120 is allowed to pass, and can conform to the medical instrument 120. The second end 176B can be slightly spaced apart from an inner surface of the cavity 166 in order to accommodate the medical instrument 120. In this way, the gate 176 can be configured to allow the medical instrument 120 to be inserted through the valve adapter 164 into the opening 162 of the third arm 148C while preventing fluid flow through the opening 160 into the cavity 166. In this way, the gate 176 can form a seal against the medical instrument 120 in the second configuration. For example, the second end 176B can be configured to contact or abut a surface of the medical instrument 120. Figure 3C The curved arrow illustrates fluid flow, for example, during or after insertion of the medical instrument 120 past the gate 176. As shown by the arrow, fluid flow can be stopped and / or reversed by the gate 176.

[0063] Referring back to Figure 2 The first end of the first conduit 178 can be coupled to the reservoir 146, for example, via the second port 146B. A tube 180 can extend from the first conduit 178 into the reservoir 146. For example, the tube 180 can be inserted into the reservoir 146 to facilitate fluid flow from the reservoir 146 into the first conduit 178. The second end of the first conduit 178 can include an adapter 182. The adapter 182 can be configured to be coupled to a pressure source (not shown) and / or the umbilical 7 (as shown in FIG. 1), for example. Figure 1In this manner, the adapter 182 can be configured to allow fluid to flow from the reservoir 146 through the tube 180 and the first conduit 178 to the medical device 20. In this manner, fluid from the reservoir 146 can be used with the medical device 20 to provide, for example, irrigation and / or lens cleaning.

[0064] In some examples, the second conduit 142 can be fluidly coupled to the second arm 148B via the opening 160. For example, the second conduit 142 can be inserted into the opening 160. Alternatively, the arm 148B can be inserted into the second conduit 142. The second conduit 142 can include a first branch 142A, a second branch 142B, and a third branch 142C. For example, the first branch 142A of the second conduit 142 can be fluidly coupled to the second arm 148B, as described above. The first branch 142A can split into the second branch 142B and the third branch 142C, each of which can extend from the first branch 142A. The second branch 142B of the second conduit 142 can include an opening / port 143. The functions of the second branch 142B and the port 143 will be discussed in further detail below. The end of the third branch 142C can be fluidly coupled to the medical device 20. For example, the third branch 142C of the second conduit 142 can be inserted or otherwise coupled to the opening 34 of the medical device 20. For example, the port defining the opening 34 can be inserted into the third branch 142C. Figure 1

[0065] The first branch 142A, the second branch 142B, and the third branch 142C can be arranged such that the medical instrument 120 can pass from the first branch 142A into the second branch 142C without diverting into the third branch 142B. Similarly, the branches 142A, 142B, and 142C can be arranged such that the medical instrument 120 can pass from the second branch 142C into the third branch 142C without diverting into the first branch 142A. For example, the angle between the first branch 142A and the third branch 142C can be relatively open / straight. The angle between the second branch 142B and the third branch 142C can similarly be relatively open / straight. Meanwhile, the angle between the second branch 142B and the first branch 142A can be relatively more acute (e.g., an acute angle).

[0066] ​During use, the medical instrument 120 can be inserted into the valve 148 via the opening 162 of the third arm 148C. In some examples, the valve adapter 164 can be coupled to the third arm 148C of the valve 148. In such examples, the medical instrument 120 can first be inserted into the opening 170 and / or channel 172 of the valve adapter 164 and then inserted into the valve 148 via the opening 162 of the third arm 148C. The medical instrument 120 can be, for example, a guidewire, a catheter, or any other medical device commonly used in the art and configured for insertion into a patient.

[0067] The medical instrument 120 can pass through the lumen 152C of the third arm 148C, through the junction 154 between the arms 148A, 148B, 148C, and 148D, and into the lumen 152B of the second arm 148B of the valve 148. In some examples, the medical instrument 120 can extend through the opening 160 of the second arm 148B and be inserted into the second catheter 142. In aspects, the medical instrument 120 can be inserted into the medical device 20 via the opening 34 (as shown) coupled to the catheter 142. Figure 1

[0068] As the medical instrument 120 passes through the valve 148, fluid from the fluid container 144 can flow into the opening 150A of the spike 150, through the lumen 152A of the first arm 148A. The fluid can flow through the junction 154 and into the lumen 152D of the fourth arm 148D, to the reservoir 146. As the fluid flows through the valve 148, and particularly through the junction 154, the fluid can flow onto the medical instrument 120. In this way, the medical instrument 120 is wetted or lubricated.

[0069] In the second configuration of the valve adapter 164, Figure 3C the gate 176 can be configured to remove excess fluid from the surface of the medical instrument 120, for example, when the medical instrument 120 is pulled proximally and / or removed from the valve adapter 164. In this way, the gate 176 can create a wiping effect on the surface of the medical instrument 120. For example, the free end 176B of the gate 176 can contact the medical instrument 120 such that, as the medical instrument 120 is pulled proximally and / or removed from the valve adapter 164, fluid from the surface of the medical instrument 120 is removed or wiped away by the gate 176. The fluid removed from the surface of the medical instrument 120 can then flow through the lumen 152C of the third arm 148C, into the lumen 152D of the fourth arm 148D, and into the reservoir 146.

[0070] Once the medical instrument 120 is pulled proximally such that the medical instrument 120 is located proximally of the gate 176, the gate 176 can transition back to the first configuration, as shown in FIG. 1A. Figure 3B ​The gate 176 can be configured to transition between the first and second configurations one or more times throughout the procedure. For example, during the procedure, when the medical instrument 120 (or multiple medical instruments 120) is inserted and / or removed multiple times, the gate 176 can be configured to transition between the first and second configurations as shown in FIGS. 17A and 17B, respectively. Thus, the adapter 164 can be configured to prevent or limit the spillage of fluid out of the valve 148 and the valve adapter 164. Figure 3B and Figure 3C Thus, the adapter 164 can be configured to prevent or limit the spillage of fluid out of the valve 148 and the valve adapter 164.

[0071] After (and during) wetting the medical instrument 120 with fluid from the fluid container 144, excess fluid can flow from the valve 148 into the reservoir 146. The excess fluid can fill the reservoir 146. Fluid from the reservoir 146 can be used with the medical device 20. For example, the excess fluid can flow into the umbilical tube 7 of the medical device 20 via the tube 180. In this way, the excess fluid can be used, for example, to deliver fluid to a target tissue via the medical device 20, or to clean a lens of an imaging device of the medical device 20.

[0072] Although not shown, in some examples, the second arm 148B can include a second gate. The second gate can be configured similarly to the first gate 176. The second gate can be composed of a flexible material and can extend across all of the second lumen 152B of the second arm 148B. The second gate can be configured to prevent or limit the flow of fluid into or out of the second arm 148B and to allow a lubricated medical instrument 120 to pass through or over the second gate and into the second arm 148B. For example, the second gate can be configured to prevent or limit the backflow of fluid from a medical device (e.g., the medical device 20) fluidly coupled to the second arm 148B. Additionally or alternatively, the second gate can be configured to prevent or limit the amount of fluid that flows from the fluid container 144 into the second arm 148B. Thus, the second gate can be configured to allow a lubricated medical instrument 120 to pass through the second arm 148B while preventing or limiting the flow of additional or excess fluid into the second arm 148B.

[0073] In some examples, the port 143 Figure 2 ) can be configured to receive a medical instrument (e.g., the medical instrument 120) such that the medical device 120 inserted into the port 143 is not wetted by the wetting system 140. The medical instrument 120 can be inserted into the port 143, through the second branch 142B of the conduit 142, and into the third branch 142C of the conduit 142. The medical instrument 120 can be inserted into the opening 34 Figure 1 ) via the third branch 142C.

[0074] One or more parts of the wetting system 140 may be reusable and / or disposable. For example, fluid container 144 may be configured to allow a user to fill or refill fluid container 144 one or more times. In some examples, valve 148 may be disposable or reusable. Additionally or alternatively, reservoir 146 may be disposable or reusable. For example, reservoir 146 may be configured to allow a user to remove liquid captured by reservoir 146 and reuse reservoir 146. In this way, components of the wetting system 140 may be made of one or more sterilizable materials.

[0075] Figure 4 A front view of an alternative wetting system 240 is shown. The wetting system 240 includes a fluid container 244, a reservoir 246, and an impregnation container 284. The fluid container 244 is in fluid communication with the reservoir 246 via a cavity of a first conduit 286. The first conduit 286 extends between the fluid container 244 and the reservoir 246. The first conduit 286 allows fluid flow from the fluid container 244 to the reservoir 246.

[0076] Fluid container 244 may have Figure 2 The fluid container 244 shown may have any or all of the following characteristics. For example, the fluid container 244 may include a first port 244A and a second port 244B. The first port 244A may be configured to allow a user to inject or withdraw fluid from the fluid container 244. The second port 244B may be configured to allow fluid flow to the reservoir 246, for example, once the second port 244B is pierced by the spike 250. The spike 250 may have any of the properties of the spike 150 and may be configured to facilitate fluid connection between the fluid container 244 and the first conduit 286. The spike 250 may be coupled to the proximal end of the first conduit 286 or may be integrally formed with the first fluid conduit 286. The flange 256 may have any of the properties of the flange 156 and may be configured, for example, to prevent excessive insertion of the spike 250 into the fluid container 244.

[0077] The reservoir 246 can be fluidly connected to the first conduit 286 via, for example, port 246A. In this way, fluid from the fluid container 244 can flow through the first conduit 286 and enter the reservoir 246. The reservoir 246 may have the features described above. Figure 2 Any or all of the characteristics of the described reservoir 146. For example, the reservoir 246 may be any flexible or rigid container configured to contain fluid.

[0078] In some examples, a first end of the second conduit 278 can be coupled to the reservoir 246. A tube 280 can extend from the second conduit 278 into the reservoir 246. A second end of the second conduit 278 can include an adapter 282 configured to be coupled to a pressure source (not shown) and / or the umbilical 7 of the medical device 20 (as shown). The second conduit 278, the tube 280, and / or the adapter 282 can each have any or all of the properties of the conduit 178, the tube 180, and / or the adapter 182 described above with respect to Figure 1 In some examples, a first end of the second conduit 278 can be coupled to the reservoir 246. A tube 280 can extend from the second conduit 278 into the reservoir 246. A second end of the second conduit 278 can include an adapter 282 configured to be coupled to a pressure source (not shown) and / or the umbilical 7 of the medical device 20 (as shown). The second conduit 278, the tube 280, and / or the adapter 282 can each have any or all of the properties of the conduit 178, the tube 180, and / or the adapter 182 described above with respect to Figure 2 During a procedure, the second conduit 278 can provide fluid from the reservoir 246 to the medical device 20, e.g., for irrigation or lens washing.

[0079] A third conduit 288 can extend radially outward from a portion of the first conduit 286. A lumen of the third conduit 288 can be in fluid communication with a lumen of the first conduit 286. The third conduit 288 can be configured to allow fluid flow between the fluid container 244 and the immersion container 284, e.g., via the first conduit 286 and the third conduit 288. The third conduit 288 can be fixedly or removably coupled to the immersion container 284.

[0080] The third conduit 288 can include a stop 290 disposed about the third conduit 288. The stop 290 can be a clamp (e.g., a roller tube clamp), a valve, a clip, or any other mechanism for controlling fluid flow through the third conduit 288. For example, in a first, closed, configuration, the stop 290 can be configured to prevent fluid flow to the immersion container 284. In the closed configuration, the stop 290 can exert an inward force on one or more sides of the third conduit 288. The stop 290 can squeeze / compress the third conduit 288 such that the walls of the third conduit 288 contact one another and close off the lumen extending through the third conduit 288. In other words, the stop 290 can pinch close the third conduit 288. In a second, open, configuration, the stop 290 can be configured to allow fluid flow through the third conduit 288 and into the immersion container 284. In the open configuration, the stop 290 can not exert an inward force on the walls of the third conduit 288 or can exert a very small force on the third conduit 288 such that the lumen of the third conduit 288 is not closed off. In some examples, the stop 290 can be configured to be manually operated by a user. In other examples, the stop 290 can be electrically operated or operated via a control module (not shown). In such examples, the stop 290 can be configured to be opened and / or closed using an electrical input.

[0081] The immersion container 284 can be configured to hold or contain fluid from the fluid container 244. In some examples, the immersion container 284 can be fixedly or removably coupled to the reservoir 246 via a coupler 292. For example, the coupler 292 can be a clip or clamp configured to permanently or temporarily couple the immersion container 284 to the reservoir 246. The coupler 292 can hold the immersion container 284 in a desired (e.g., upright) configuration. In some examples, the coupler 292 can include an adhesive or sticky material such that the coupler 292 can be temporarily or permanently adhered to the reservoir 246.

[0082] The immersion container 284 can have a shape similar to a test tube. For example, the immersion container 284 can have a first open end 284A and a second closed end 284B. A portion (or all) of the immersion container 284 can have a generally cylindrical shape.

[0083] The medical instrument 120 can be inserted into the immersion container 284 via the first open end 284A. By inserting the medical instrument into the immersion container 284, the medical instrument 120 can be wetted or lubricated with fluid that has traveled from the fluid container 244 into the immersion container 284 by the first conduit 286 and the third conduit 288.

[0084] To use the wetting system 240, a user can first puncture the second port 244B with the spike 250. With the stop 290 on the third conduit 288 in the closed position, fluid can begin to flow from the fluid container 244 into the reservoir 246 via the first conduit 286. To fill the immersion container 284, the stop 290 can be moved to the open position, allowing fluid to flow through the third conduit 288 and into the immersion container 284. In this way, the immersion container 284 can be at least partially filled with fluid from the fluid container 244. With the stop 290 in the open position, fluid flow from the fluid container 244 into the reservoir 246 can be reduced or prevented. Once the immersion container 284 is filled with a desired amount of fluid (e.g., to a desired level of the immersion container 284), the stop 290 can be moved to the closed position, preventing fluid flow into the immersion container 284. With the stop 290 in the closed position, fluid from the fluid container 244 can again flow into the reservoir 246 without any diversion of fluid to the immersion container 284. Fluid within the reservoir 246 can be used by the medical device 20, for example, to supply fluid to a target tissue and / or to clean a lens of an imaging device. For example, as discussed above, the second conduit 278 can be fluidically coupled to the reservoir 246 and one or more portions of the medical device 20. The second conduit 278 can facilitate fluid flow from the reservoir 246 and into the medical device 20.

[0085] With the impregnation container 284 at least partially filled with fluid, the medical implement 120 can be inserted into the impregnation container 284 via the first open end 284A. In this manner, the medical implement 120 can be wetted or lubricated. The lubricated medical implement 120 can then be inserted into a patient and / or into a working channel of the medical device 20 via, for example, the opening 34 (as shown) via the working channel 32. Figure 1

[0086] Figure 5 An alternative wetting system 340 is shown. The wetting system 340 can include a fluid container 344 and an impregnation container 384. The fluid container 344 can have any or all of the characteristics of the fluid container 144 discussed with reference to Figure 2 and / or the fluid container 244 discussed with reference to Figure 4 For example, the fluid container 344 can have a first port 344A and a second port 344B. One or both of the first port 344A and the second port 344B can have any or all of the characteristics discussed above with respect to the first port 144A and the second port 144B of the fluid container 144 and / or the first port 244A and the second port 244B of the fluid container 244. Although Figure 2 Figure 4 Figure 5 a reservoir similar to the reservoir 146, 246 is not depicted in the

[0087] The impregnation container 384 can be fluidly coupled to the fluid container 344 via a conduit 386. For example, a first end 386A of the conduit 386 can be coupled to a first (bottom) end 384B of the impregnation container 384. The impregnation container 384 can be similar to a small cup and can have any suitable shape (e.g., conical / truncated conical, bowl-shaped, cylindrical, etc.). As Figure 5 ​​​As shown, the diameter / width of the bottom end 384A of the immersion container can be substantially equal to the diameter / width of the conduit 386. Alternatively, the bottom end 384A of the immersion container 384 can be wider than the conduit 386. The bottom end 384A of the immersion container 384 can include an opening such that fluid can flow through the conduit 386, through the opening of the bottom end 384A, and into the immersion container 384. In some examples, the opening of the bottom end 384A can extend across the entire diameter / width of the bottom end 384A. Alternatively, the opening of the bottom end 384A can extend across only a portion of the bottom end 384A. The opening of the bottom end 384A can have a width that is the same as the width of the lumen of the conduit 386. The conduit 386 can be a separate element from the immersion container 384 and attached to the bottom end 384A of the immersion container 384. In an alternative, the conduit 386 can be coupled to a side surface of the immersion container 384, and the sidewall of the immersion container 384 can have an opening for fluidly coupling the immersion container 384 to the conduit 386.

[0088] The immersion container 384 can have a second (top) end 384B opposite the bottom end 384A. The second end 384B can be at least partially open (e.g., open across the diameter / width of the second end 384B). In some aspects, the second end 384B can include a removable cap or top that is configured to open and close over the opening of the second end 384B. For example, a user can open or remove the cap or top to insert the medical implement 120 into the immersion container 384. Once the medical implement is removed from the immersion container 384, the user can subsequently close or replace the cap or top to prevent spillage from the immersion container 384. As Figure 5 As shown, the walls of the immersion container 384 can taper radially outward from the bottom end 384A to the second end 384B. However, this shape is merely exemplary, and the immersion container 384 can have any suitable shape.

[0089] The second end 386B of the conduit 386 can include a needle 350 configured to be inserted into the second port 344B, allowing fluid flow between the fluid container 344 and the immersion container 384. In some examples, the second port 344B can include a self-sealing silicone configured to be pierced multiple times by the needle 350 without leaking. For example, the second port 344B can be configured similar to a septum of a subcutaneous injection port commonly used in chemotherapy. In other aspects, the needle 350 can be configured similar to and / or have any of the properties of the spike 150 and / or the spike 250. In such aspects, the second port 344B can have any of the properties of the second port 144B and / or the second port 244B.

[0090] Once the immersion container 384 is fluidly coupled to the fluid container 344 via the conduit 386, fluid can begin to flow into the immersion container 384. The immersion container 384 can begin to fill according to the principle of the communicating vessels. For example, the immersion container 384 can begin to fill to the same level as the fluid in the fluid container 344. In this way, the immersion container 384 and the fluid in the fluid container 344 can have the same level.

[0091] The immersion container 384 can be removably coupled to the fluid container 344 via the coupler 392. The coupler 392 can have any or all of the characteristics of the coupler 292 discussed above. For example, the coupler 392 can be a clip or clamp configured to couple the immersion container 384 to the fluid container 346. In some examples, the coupler 392 can be removably attached to the fluid container 344 and / or the immersion container 384. In other examples, the coupler 392 can be fixedly coupled to the immersion container 384 and removably coupled from the fluid container 344. In further examples, the coupler 392 can be fixedly coupled to the fluid container 344 and removably coupled from the immersion container 384. In some examples, the coupler 392 can include an adhesive or sticky material such that the coupler 392 can adhere to the fluid container 344. For example, one or both of the coupler 392 or the fluid container 344 can include an adhesive material. Figure 4 Figure 4 The immersion container 384 can be coupled to the fluid container 344 at any location on the fluid container 344 (e.g., on a side of the fluid container 344). For example, the immersion container 384 can be positioned along a side of the fluid container 344 according to a current level of the fluid container 344 and / or a desired level in the immersion container 384. For example, the immersion container 384 can be positioned along a side of the fluid container 344 such that the second end 384B of the immersion container 384 is above the fluid level contained within the fluid container 344 and the bottom end 384A is below the fluid level contained within the fluid container 344. Thus, according to the principle of the communicating vessels, fluid will flow into the immersion container 384 but not overflow from the second end 384B of the immersion container 384. If the second end 384B is below the fluid level contained within the fluid container 344, the immersion container 384 can become overfilled / overflow.

[0092] The immersion container 384 can be coupled to the fluid container 344 at any location on the fluid container 344 (e.g., on a side of the fluid container 344). For example, the immersion container 384 can be positioned along a side of the fluid container 344 according to a current level of the fluid container 344 and / or a desired level in the immersion container 384. For example, the immersion container 384 can be positioned along a side of the fluid container 344 such that the second end 384B of the immersion container 384 is above the fluid level contained within the fluid container 344 and the bottom end 384A is below the fluid level contained within the fluid container 344. Thus, according to the principle of the communicating vessels, fluid will flow into the immersion container 384 but not overflow from the second end 384B of the immersion container 384. If the second end 384B is below the fluid level contained within the fluid container 344, the immersion container 384 can become overfilled / overflow.

[0093] ​When the liquid level in the fluid container 344 increases (e.g., by injecting fluid into the fluid container 344 via the first port 344A) or decreases, the impregnation container 384 can be repositioned on the fluid container 344. Specifically, when the liquid level in the fluid container 344 decreases, the impregnation container 384 can move downwards on the fluid container 344, causing the impregnation container 384 to fill, as described above. When the liquid level in the container increases, the impregnation container 384 can move upwards relative to the fluid container 344 to prevent overflow. Therefore, a desired liquid level can be maintained within the impregnation container 384.

[0094] Once the impregnation container 384 is filled to the desired liquid level, the medical device 120 can be inserted into the impregnation container 384. For example, the distal end of the medical device 120 can be inserted into the impregnation container 384 so that the distal end of the medical device 120 is wetted or lubricated. When the medical device 120 is wetted, it can be accessed via, for example, an opening 34 (such as...). Figure 1 (As shown) Insert the medical device 120 into the patient's body or into the medical device 20.

[0095] Figure 6 An alternative wetting device 440 is shown. The wetting device 440 may include a fluid container 444 and an impregnation portion 484. In addition to the following, the fluid container 444 may have the features described above. Figure 2 Fluid container 144 Figure 4 Fluid containers 244 and / or Figure 5 The fluid container 344 may have any or all of the characteristics described. For example, the fluid container 444 may be a bag or a bottle.

[0096] The impregnated portion 484 can be integrally molded with the fluid container 444. In some examples, the impregnated portion 484 can be formed of the same material as the fluid container 444. In other examples, the impregnated portion 484 can be formed of a different material than the fluid container 444. Figure 6 As shown, the outer wall 484A of the impregnation portion 484 may extend along at least a portion of the side of the fluid container 444. In some examples, the outer wall 484A of the impregnation portion 484 may extend along the entire length of the side of the fluid container 444, for example, between the top and bottom of the fluid container 444. The impregnation portion 484 may have an opening 484B at its top end.

[0097] The wall 445 of the fluid container 444 can separate the immersion portion 484 from the fluid container 444. For example, the wall 445 can define one of the walls of each of the fluid container 444 and the immersion portion 484. The wall 445 can not extend along the entire length of the fluid container 444, such that an opening 449 is formed to allow fluid communication between the fluid container 444 and the immersion portion 484. For example, as shown in FIG. 4A, the wall 445 can terminate above the bottom of the fluid container 444 / immersion portion 484, such that the opening 449 is formed below the wall 445. Alternatively, the wall 445 can include an opening formed therein that is located above the bottom of the wall 445. In some examples, the wetting device 440 can be a pouch, and the wall 445 can be formed by fusing or coupling the walls of the pouch together. For example, the wall 445 can be formed by fusing the two sides of the wetting device 440 using heat. Alternatively, the wall 445 can be formed using an adhesive. In this way, the two sides of the wetting device 440 can be fused or formed together to form the fluid container 444 and the immersion portion 484. Alternatively, the fluid container 444, the immersion portion 484, and the wall 445 can be formed by any suitable method, such as molding, subtractive manufacturing, or additive manufacturing. Figure 6

[0098] In some examples, the fluid container 444 optionally includes a stop 490. The stop 490 can be disposed on or within the fluid container 444 to control fluid flow between the fluid container 444 and the immersion portion 484. The stop 490 can be a clamp, a valve, a clip, or any other mechanism for controlling the flow of fluid from the fluid container 444 into the immersion portion 484. In some examples, the stop 490 can be a one-way valve configured to allow fluid flow into the immersion portion 484 and prevent fluid flow from the immersion portion 484 into the fluid container 444. In examples having a stop 490, the outer wall 484A can extend along a portion of the side of the fluid container 444 such that the opening 484B of the immersion portion 484 is located below the top side of the fluid container 444.

[0099] In a first, closed, configuration, the stop 490 can be configured to prevent fluid flow from the fluid container 444 into the immersion portion 484. In a second, open, configuration, the stop 490 can be configured to allow fluid flow from the fluid container 444 into the immersion portion 484. In some examples, the stop 490 can be configured to be manually operated (open / closed) by a user. In other examples, the stop 490 can be electrically operated or operated via a control module (not shown). In this way, the stop 490 can be configured to be opened and / or closed using an electrical input.

[0100] ​In some examples, port 444A of fluid container 444 can be configured to be pierced at the end of conduit 486 by spike 450. Although Figure 6 Not shown, but conduit 486 can be connected to any reservoir having the properties described above. Fluid from the reservoir can be used during medical procedures, as described above. Alternatively, the reservoir can be omitted, and fluid from fluid container 444 can be transferred via conduit 486 to medical device 20 for use during procedures.

[0101] To fill the impregnation section 484 with fluid, the stop 490 can be opened, allowing fluid to flow into the impregnation section 484. The impregnation section 484 will be filled according to the principle of communicating vessels. For example, the impregnation section 484 can be filled until the liquid level in the impregnation section 484 is the same as the liquid level in the fluid container 444. The amount of fluid in the impregnation section 484 can be controlled, for example, via the stop 490. For example, if the user desires less fluid in the impregnation section 484, the stop 490 can be closed, thereby preventing fluid flow between the fluid container 444 and the impregnation section 484. In this way, the amount of fluid in the impregnation section 484 can be controlled. Alternatively, if the stop 490 is omitted, fluid can automatically flow into the impregnation section 484 and can fill to the fluid level in the fluid container 444. In this alternative, the outer wall 484A of the impregnation portion 484 may extend along the side of the fluid container 444, such that the opening 484B of the impregnation portion 484 is located above the fluid line in the fluid container 444. In this way, the fluid in the impregnation portion 484 can be filled to the same level as the fluid in the fluid container 444 without overflowing.

[0102] To lubricate the medical device 120, it can be inserted through the opening 484B of the impregnation portion 484. For example, the medical device 120 can be at least partially inserted into the impregnation portion 484, such that the medical device 120 is wetted. Once the medical device is wetted, it can be inserted into the patient's body or through the working channel of the medical device 20 (e.g., via the opening 34), as described above. Figure 1 As shown.

[0103] Figures 7A-7C It shows the first form ( Figure 7A ), second form ( Figure 7B ) and the third form ( Figure 7C The alternative wetting system 540 in the above description is as follows. The wetting system 550 includes a fluid container 544, a movable valve 548, and an impregnation container 584. The fluid container 544 may have a reference... Figure 2 Fluid containers discussed 144, Reference Figure 4 Fluid containers discussed 244, ReferenceFigure 5 The fluid container 344 discussed and / or referenced Figure 6 Any or all of the properties of the fluid container 444 discussed. The immersion container can have any or all of the properties of the fluid container 344 discussed and / or referenced Figure 4 The immersion container 284 discussed and / or referenced Figure 5 Any or all of the properties of the immersion container 384 discussed.

[0104] In some aspects, the immersion container 584 can include an opening 584A configured to receive at least a portion of a medical instrument (not shown). For example, during use, a portion of a medical instrument (not shown) can be inserted into the immersion container 584 via the opening 584A. Although not shown, in some aspects, the immersion container 584 can be fixedly or removably coupled to the fluid container 544 via, for example, a coupler. For example, the coupler can have any or all of the properties of the coupler 292 discussed and / or referenced Figure 4 The coupler 292 discussed and / or referenced Figure 5 Any or all of the properties of the coupler 392 discussed.

[0105] The first conduit 586 can extend between the fluid container 544 and the valve 548. Although not depicted in Figures 7A-7C The first conduit 512 can have a spike or needle (having any of the properties of the spike or needle discussed above) or other structure for selectively connecting the first conduit 512 with the fluid container 544 (e.g., with a port of the fluid container 544).

[0106] The second conduit 542 can extend from the valve 548 (e.g., radially outward from the valve 548). Although not shown in Figures 7A-7C The second conduit 542 can be coupled to a reservoir having any of the properties of the reservoirs described above. Fluid from the reservoir can be utilized during a medical procedure, as described above. In the alternative, the reservoir can be omitted, and the second conduit 542 can extend to and be fluidly connected to a medical device, such as, for example, Figure 1 The medical device 20 of FIG. 1.

[0107] The third conduit 588 can extend between and fluidly connect the valve 548 and the immersion container 584. As discussed above with respect to the immersion container 384, the immersion container 584 can have an opening therein coupled to the third conduit 588 such that the third conduit 588 is in fluid communication with the third conduit 588. For example, as described above, a bottom surface of the immersion container 584 can include an opening connected to the third conduit 588. In the alternative, the immersion container 584 can be omitted, and the third conduit 588 can terminate at a free end. A separate cup, bottle, or other type of container can be filled with fluid that flows through the free end of the third conduit 588.

[0108] Valve 548 may include cavity 551, which may define a path through which fluid may flow. For example... Figures 7A-7C As shown, valve 548 may have a generally circular or spherical shape, and cavity 551 may have a curved path. Cavity 551 may extend from a first opening 551A on the surface of valve 548 to a second opening 551B also on the surface of valve 548. In some examples, the central angle between the first opening 551A and the second opening 551B may be approximately 120 degrees.

[0109] In the first form, such as Figure 7A As shown, each end of cavity 551 can be aligned with the first conduit 512 and the second conduit 542. For example, the first opening 551A can be aligned with the first conduit 586, and the second opening 551B can be aligned with the second conduit 542. Therefore, valve 548 can be configured to allow fluid to flow from fluid container 544 through the first conduit 586 and the second conduit 542 via cavity 554. In this way, fluid from fluid container 544 can be delivered to a medical device (e.g., medical device 20). In the first configuration, fluid flow to immersion container 584 is not permitted because cavity 551 is not aligned with the third conduit 588.

[0110] In the second configuration of valve 548, such as Figure 7B As shown, cavity 551 can be aligned with the second conduit 542 and the third conduit 588. For example, first opening 551A can be aligned with the second conduit 542, and second opening 551B can be aligned with the third conduit 588. In the second embodiment, fluid can be allowed to flow between the impregnation container 584 and the reservoir or medical device (e.g., medical device 20). Because the impregnation container may be above 584 and / or there may be no pressure causing fluid to move upward from the reservoir or medical device into the impregnation container 584, in the second embodiment, fluid can flow from the impregnation container 584 through the third conduit 588, through cavity 551, and through the second conduit 542. In this way, the impregnation container 584 can be emptied. Figure 7B In this configuration, the fluid flow from the fluid container 544 can be shut off (not allowed).

[0111] In the third configuration of valve 548, such as Figure 7CAs shown, the cavity 551 can be aligned with the first conduit 512 and the third conduit 588. For example, the first opening 551 A can be aligned with the third conduit 588, and the second opening 551 B can be aligned with the first conduit 586. Thus, fluid can flow between the fluid reservoir 544 and the immersion reservoir 584. In the event that the fluid level in the immersion reservoir 584 is lower than the fluid level in the fluid reservoir 544, fluid can flow from the fluid reservoir 544, through the first conduit 586, through the cavity 551, through the third conduit 588, and into the reservoir 584, according to the principle of the communicating vessels as discussed above. In this manner, the immersion reservoir 584 can be filled with fluid from the fluid reservoir 544.

[0112] The valve 548 can be configured to transition or move between each of the modalities (e.g., the first modality, the second modality, and the third modality) by various mechanisms. For example, rotation (e.g., clockwise or counterclockwise) of the valve 548 can cause the valve 548 to transition between each of the modalities. Additionally or alternatively, the valve 548 can include one or more buttons, actuators, levers, or the like that are configured to cause the valve 548 to transition to each of the modalities. In some examples, the valve 548 can be electrically operated. For example, the valve 548 can be configured to transition between each of the modalities via an electrical input. The arrangements and types of the valve 548 described above are merely exemplary, and any suitable type of valve can be utilized in order to fluidly couple the conduits, as described above. The valve 548 and / or the conduits 542, 586, 588 can include one-way valves to prevent fluid from flowing in directions other than those described herein. In some examples, the valve 548 can be a two-way valve, and the second conduit 586 can be omitted. Figure 7B of the second modality.

[0113] To lubricate a medical instrument (not shown), the immersion reservoir 584 can be filled. For example, the valve 548 can be moved to the third modality ( Figure 7C ), such that fluid from the fluid reservoir 544 flows into the immersion reservoir 584. Once the immersion reservoir 584 contains a desired volume of liquid, the valve 548 can be moved to the first modality ( Figure 7A ). With fluid in the immersion reservoir 584, a medical instrument (not shown, but having any of the features of the medical instrument 120) can be inserted or immersed into the immersion reservoir 584 such that a portion of the medical instrument is wetted or lubricated. Once a desired length or portion of the medical instrument is wetted, the medical instrument can be inserted into a patient and / or inserted through a working channel of a medical device (e.g., Figure 1 ).

[0114] To fill a reservoir (not shown, but having any of the features of any of the reservoirs shown and described above) or to allow fluid flow to a medical device (e.g., Figure 1The valve 548 can be transitioned to or can remain in the first configuration.

[0115] In some cases, it can be necessary or desirable to drain fluid from the impregnation container 584. In such cases, the valve 548 can be transitioned to a second configuration (not shown). Figure 7B In the second configuration, fluid can be allowed to flow from the impregnation container 584 through the valve 548, to, for example, a medical device and / or into a reservoir or disposal container.

[0116] The valve 548 can be moved between each configuration multiple times to achieve a desired result. For example, throughout a surgical procedure, the valve 548 can be transitioned from the first configuration (not shown) Figure 7A to a third configuration (not shown) Figure 7C to fill and / or refill the impregnation container 584 one or more times. Similarly, throughout a surgical procedure, the valve 548 can be transitioned to the second configuration (not shown) Figure 7B one or more times, for example, to drain the impregnation container 584. Once the impregnation container 584 is drained, the impregnation container 584 can be replenished with fresh fluid by transitioning the valve to the third configuration (not shown) Figure 7C In this way, the impregnation container 584 can be periodically provided with fresh fluid so that a medical instrument (not shown) can be lubricated or wetted with fresh fluid.

[0117] Figure 8A and Figure 8B A front view (not shown) Figure 8A and a side view (not shown) Figure 8B of portions of an example wetting system 640 are shown. The wetting system 640 can include a fluid reservoir 681 coupled to a wetting module 663. A conduit 686 can extend from an upper surface (or another surface) of the wetting module 663. The conduit 686 can be fluidly coupled to a fluid source (not shown). The fluid source can be a fluid container, such as, for example, any of the fluid containers previously discussed herein (e.g., the fluid container 144, the fluid container 244, the fluid container 344, the fluid container 444, and / or the fluid container 544). In some examples, the fluid source can be a pressurized fluid source.

[0118] The conduit 686 can be coupled to an adapter 657. The adapter 657 can be configured to allow fluid flow from the fluid source (a) through the conduit 686 to the wetting module 663 and (b) through the second conduit 642. Although not shown, the second conduit 642 can be fluidly coupled to a medical device (e.g., the medical device 20) Figure 1The adapter 657 can be configured to allow fluid flow through the other catheter (not shown), for example, to accommodate fluid flow to multiple medical devices. In some examples, the adapter 657 can be configured to allow fluid flow through the medical device 20) or reservoir (any of the features of the reservoirs disclosed herein). In some examples, the adapter 657 can be configured to allow fluid flow through other catheters (not shown), for example, to accommodate fluid flow to multiple medical devices.

[0119] The wetting module 663 can include a nozzle arm 665 and a base 669. The nozzle arm 665 and the base 669 can be coupled via a bridge portion 667. For example, the nozzle arm 665 can extend laterally from the bridge portion 667 in a first direction. The base 669 can extend laterally from the bridge portion 667 in the same first direction. The nozzle arm 665 can be disposed above and spaced apart from the base 669. In this way, a gap 671 can be formed between the nozzle arm 665 and the base 669. The bridge portion 667 can form a first side of the gap 671. In this way, the gap 671 can be C-shaped. For example, the gap 671 can be defined by a bottom surface of the nozzle arm 665, a top surface of the base 669, and the bridge portion 667. The gap 671 can be open on three sides, allowing a user to access the gap 671 from at least three sides (e.g., a first side, a second side, and a third side) of the wetting module 663. In this way, the gap 671 can be configured to receive a medical instrument 120 (e.g., a catheter) as shown. Figure 8B

[0120] In some examples, an absorbent material 673 can be disposed between the nozzle arm 665 and the base 669, for example, within the gap 671. The absorbent material 673 can be a sponge-like material, for example, configured to hold moisture. In this way, when fluid is delivered from the nozzle arm 665, excess fluid can be held by the absorbent material 673. In some examples, the absorbent material 673 can be located on an underside of the gap 671 (e.g., on an upper surface of the base 669). In other examples, the absorbent material 673 can be located on multiple sides of the gap 671, for example, along a surface of the bridge portion 667 and / or along a lower surface of the nozzle arm 665.

[0121] ​Nozzle arm 665 can be configured to provide fluid through gap 671. For example, nozzle arm 665 can be configured to spray and / or drip fluid through gap 671. Excess fluid can be captured by container 675 disposed within base 669. In some examples, absorbent material 673 can cover container 675. Container 675 can be conical or funnel-shaped. For example, excess fluid from nozzle arm 665 can be captured by container 675. Container 675 can be fluidly coupled to reservoir 681. Reservoir 681 can be fixedly or removably coupled to wetting module 663. In some examples, reservoir 681 can be removable, such that, for example, reservoir 681 can be emptied and / or replaced. In other examples, reservoir 681 can be fixedly coupled to wetting module 663. In such examples, reservoir 681 can include a port or drain outlet, such that reservoir 681 can be emptied or discharged.

[0122] The wetting module 663 may include a controller 677 disposed on the rear surface of the wetting module 663. The controller 677 may be configured to control one or more aspects of fluid flow. For example, the controller 677 may control the amount of fluid delivered (e.g., sprayed or dripped), the intensity of the delivered fluid (e.g., pressure), the temperature of the fluid, etc. In some examples, the controller 677 may be an on / off switch configured to allow or stop fluid flow through the nozzle arm 665. The controller 677 may include actuators (e.g., knobs, levers, buttons, switches, etc.). In some examples, the controller 677 may be manually operated. For example, a user may manually adjust the controller 677. In other examples, the controller 677 may be operated via an electrical input. For example, a computer (not shown) may be configured to adjust the controller 677. In other examples, as discussed below, the controller 677 may automatically activate flow through the nozzle arm 665 (e.g., based on sensing that the medical device 120 is located below the nozzle arm 665).

[0123] like Figure 8B As shown, during use, a portion of the medical device 120 can be inserted through the gap 671. When the medical device 120 moves through the gap 671 and is positioned below the nozzle arm 665, fluid can be delivered from the nozzle arm 665 to the surface of the medical device 120. The fluid can be sprayed or dripped onto the surface of the medical device 120. In this way, the surface of the medical device 120 can be wetted or lubricated. Alternatively or additionally, the medical device 120 can move along or through the absorbent material 673, such that the absorbent material 673 wets the surface of the medical device 120.

[0124] Once the fluid is applied to the desired portion of the medical implement 120, such that the medical implement 120 is wetted or lubricated, the medical implement 120 can be removed from the wetting module 663 and inserted into a patient or through a working channel of a medical device (e.g., the medical device 20) of the medical device 20. Figure 1

[0125] In some examples, the wetting module 663 can include one or more sensors 679. The one or more sensors 679 can be motion sensors, for example, that are configured to identify when the medical implement 120 is passing through the gap 671. The one or more sensors 679 can be electrically coupled to the controller 677. For example, when the medical implement 120 passes through the gap 671, the sensor 679 can provide an electrical signal to the controller 677 to open the nozzle arm 665 to deliver the fluid. Once the medical implement 120 is removed from the gap 671, the sensor 679 can be configured to provide an electrical signal to the controller 677 to close the nozzle arm 665, such that the fluid is no longer delivered.

[0126] Figure 9 A ring 700 is shown. The ring 700 includes a looped tube 701 held in place by a plurality of clips 702. A first end 701 A of the tube 701 can include an adapter 704. The adapter 704 can define one or more lumens that can be in fluid communication with a lumen of the tube 701. The adapter 704 can be configured to be removably or fixedly coupled to a fluid source (not shown). For example, the adapter 704 can include a shaft 705 and an arm 706. The arm 706 can extend generally perpendicular to the shaft 705. Alternatively, the arm 706 can extend at any suitable angle to the shaft 705. The adapter 704 (including the shaft 705 and the arm 706) can have a "T" shape. The arm 706 and the shaft 705 can each have a lumen extending therethrough. The lumens of the arm 706 and the shaft 705 can be in fluid communication with each other. The arm 706 can include an opening 706A on a free end of the arm 706 (the end of the arm that is not coupled to the shaft 705). The opening 706A can provide access to the lumen of the arm 706.

[0127] ​The opening 706A can be selectively coupled to a fluid source (not shown). In some examples, the fluid source can be a fluid syringe. The syringe can be coupled to the arm 706 of the adapter 704 such that water can be injected into the lumen of the adapter 704 and, in turn, into the tube 701. In some examples, the adapter 704 can include a seal 707 on at least one end of the adapter 704. The seal 707 can be configured to prevent fluid from escaping from the tube 701. In some modalities, the seal 707 can include an opening through which at least a portion of the medical instrument can extend. For example, the seal 707 can be positioned between the open side of the arm 706 and the shaft 705. The seal 707 can extend around or at least partially around the medical instrument 720. In this way, the seal 707 can form a fluid-tight seal around the medical instrument 720.

[0128] The tube 701 can include a cap 703 fixedly or removably coupled to the second end 701B of the tube 701. The cap 703 can be configured to prevent fluid from escaping from the tube 701. In this way, the medical instrument 720 can be wetted or lubricated prior to removal from the tube 701. The cap 703 can include a pressure release valve 709. For example, the pressure release valve 709 can release air trapped within the tube 701 as liquid is injected into the tube 701.
