Technical Field
[0003] This disclosure relates to modular pre - loaded medical implants and delivery systems.
Background Art
[0004]
[0003] Many implantable medical devices are adapted to be delivered to a target location within a patient using a delivery system. The delivery system generally includes an external handle sub - assembly that facilitates one or more aspects of implant delivery and implantation. Some medical devices are connected to the delivery system during manufacture and packaged with the delivery system. During a medical procedure, the implant will be disconnected and detached from the delivery system to fully implant the medical device.
[0005]
[0004] For various reasons, some medical procedures may require that two or more implants be prepared and ready to be implanted at any time as needed. For example, if an implant is damaged when it comes out of its packaging or is unsafe, another implant may need to be taken out of its packaging and used instead. Also, some medical procedures may require that multiple implants be ready at any time, each having at least one physical characteristic different from at least one of the other available implants. For example, some procedures may involve delivering implants to anatomical locations where there is some variability in size and / or configuration among patients. Details of a patient's anatomical structure may not be known or confirmed until the procedure begins, and these will be determined using one or more imaging techniques (e.g., X-ray, fluoroscopy, etc.). Depending on the anatomical structure of a particular patient, implants of different sizes and / or configurations must be available as needed. The configuration of the implants and / or the way the implants are used may also influence how many implants must be ready to be implanted at any time for any particular procedure. For example, the number and configuration of individual implant components may necessitate having several implants with different components of varying sizes. In addition, the various feasible sizes and / or configurations for one or more individual components may require a matrix of implant candidates with components of different sizes and / or configurations, all of which must be shipped for a specific procedure and available for use at any time during the procedure. Depending on the procedure, several implants may be required and made available for selection—more than five, more than ten, or in some cases more than fifteen or even more.
[0006]
[0005] When the delivery system is attached to the implant during manufacturing and packaged in this manner, each package (e.g., box) will have a complete system including the implant plus a potentially bulky handle. For medical procedures that require several or many implants to be available for use, multiple packages, each containing a delivery system attached to an implant, may be needed close at hand for medical personnel.
[0007]
[0006] In addition, some medical procedures are performed in the cardiac catheterization laboratory ("catheter lab"), where there is often little space available for medical supplies such as packaging and boxes containing implants and delivery systems. In some cases, the number of delivery system and implant packages is so large that they have to be placed outside the catheter lab, forcing medical staff to leave the catheter lab during a procedure to retrieve the desired implant.

[0044]
[0054] This disclosure relates to a solution for medical implant packaging and delivery systems that can avoid the need to package many complete systems, including an external handle connected to a medical implant. This disclosure relates to a modular pre-loaded implant subassembly that can be packaged separately from the handle subassembly, providing the ability to use any one of many separately packaged modular pre-loaded implants with a common handle. This eliminates the need to pre-connect the implant to the delivery system and package it together with the delivery system, and thus potentially eliminates a considerable amount of packaging and a considerable amount of space required to store the packaged implants during medical procedures.
[0045]
[0055] One aspect of the disclosure describes an implant and delivery system including an implant subassembly adapted to be coupled to a handle subassembly during a medical procedure. The implant subassembly may be packaged separately from the handle subassembly.
[0046]
[0056] Figure 1 shows an example of an implant and delivery system 100 in a disconnected state. The system 100 includes an implant subassembly 300 adapted to connect to a handle subassembly 200 during a medical procedure. Figure 1 shows the two subassemblies before connection, after being removed from separate packaging.
[0047]
[0057] The implant subassembly 300 includes a cartridge 310 and an implant (not visible in Figure 1) positioned within the cartridge 310, the implant being optionally folded and positioned within the cartridge. The implant positioned within the cartridge includes a proximal end of the implant, also not visible in Figure 1. The implant subassembly 300 also includes an elongated flexible tubular member 320 having a distal end (not visible in Figure 1) connected to the proximal end of the implant. The implant subassembly includes a proximal end 330. The elongated flexible tubular member 320 may be configured as a tubular member or as a helical coil member.
[0048]
[0058] In this embodiment, the handle subassembly 200 includes a handle 210 and an elongated tubular member 250 extending within the handle 210 and further distally from the handle 210. The handle 210 also includes an outer housing or shell 212 and a handle actuator 214. The actuator 214 is adapted to be actuated by a user and is operably in communication with the elongated tubular member 250, and the operation of the handle actuator 214 causes axial motion of the elongated tubular member 250, which will be described in more detail later. The tubular member 250 has a distal end 252 and a lumen extending through the tubular member 250 and communicating with the distal end 252. The distal end 252 and the lumen within the tubular member 250 are sized and configured to receive the proximal end 330 of the implant subassembly 300, the implant flexible tubular member 320, and the implant first and implant second connecting members, which will be described later.
[0049]
[0059] Figure 2 depicts packaging 400 as an example for a handle subassembly 200, which has a recess for the handle 210 and a recess for receiving the elongated tubular member 250. One or more sections of the elongated tubular member 250 are adapted to be housed in a non-linear configuration as shown and are configured to return to a linear configuration when removed from packaging 400. One or more sections of the elongated tubular member 250 may also be housed in a linear configuration as shown. The elongated tubular member 250 may be housed in other configurations not shown, any of which may have some degree of nonlinearity in one or more sections along the length of the elongated tubular member 250 within the packaging. Packaging the elongated tubular member 250 in a configuration that is not perfectly straight also reduces the length dimension of the packaging required for the handle subassembly.
[0050]
[0060] In some embodiments that are merely illustrative, the elongated tubular handle member 250 may be made of a flexible tubular material that allows for some degree of bending for packaging. In addition to flexibility (for packaging), the material of the elongated tubular member 250 may also allow for the rigidity necessary for buckling avoidance and implant operation.
[0051]
[0061] Figure 3 illustrates packaging 500 as an example for an individual implant subassembly. The tubular member 320 can optionally be configured in a non-linear configuration as shown to reduce packaging size. The flexibility of the illustrated tubular member 320 would allow individual modular pre-loaded implants to be placed in much smaller packaging than if they were assembled to a handle and packaged as a single unit.
[0052]
[0062] Figures 4A and 4B illustrate implant 600 for illustrative purposes only, showing implant 600 already detached from the handle subassembly and further illustrated in an extended implantation configuration. Implant 600 is one embodiment of an implant that may be packaged as a modular pre-loaded implant according to the disclosure herein. As will be understood, a wide variety of other implants will benefit from incorporating the modular pre-loaded implant concept herein, and implant 600 is merely an illustrative implant. Figure 4B illustrates the proximal region 610 in more detail, including the proximal anchor eyelet 614 and the loop-shaped element 612, which may also be referred to herein as the arrowhead.
[0053]
[0063] Figure 5 illustrates an exemplary coupling mechanism 332, shown connected to the proximal end 610 of the implant 600. In this embodiment, the coupling mechanism holds the implant 600 until it is fully released and ready for implantation in the patient. The coupling mechanism in this embodiment includes a first coupling member 340 and a second coupling member 350. As will be described in more detail later, the first coupling member 340 and the second coupling member 350 are adapted to connect to the proximal end 610 of the implant in a first state and to release the proximal end 610 of the implant in a second state. Generally, in the first coupling state, the second coupling member 350 has a loop-shaped distal end configuration extending into the opening created by the arrowhead 612. The first connecting member 340 (sometimes referred to herein as the lock wire) extends through the second connecting member 350 and the arrowhead 612, and in this configuration, the arrangement between the first and second connecting members and the proximal end of the implant prevents the implant from being released. To release the implant 600, the first connecting member 340 is pulled proximal beyond the arrowhead 612, thereby releasing the proximal end of the implant, which will be described in more detail later.
[0054]
[0064] The first connecting member 340 and the second connecting member 350 extend through the flexible tubular member 320, as shown in Figure 5, and are connected to the respective implant subassembly components at the proximal end of the implant subassembly, as shown in detail in Figures 6-8.
[0055]
[0065] After one of the medical implants is selected from the available implants, the selected modular pre-loaded implant subassembly is removed from its individual packaging, such as packaging 500 shown in Figure 3. A handle subassembly, which may be adapted for use with any of the implant subassemblies, is also removed from its separate packaging. The proximal end 330 of the implant subassembly 300 is then front-loaded into the distal end 252 of the handle subassembly. The flexible tubular member 320, in which the first and second connecting members are located, is advanced proximal through the elongated member 250 into the handle 210.
[0056]
[0066] One aspect of this disclosure is a separate, modular, pre-loaded implant subassembly including a proximal end that can be advanced into a delivery handle and locked in place by a medical professional during a medical procedure, which provides the packaging advantages described herein. Figure 5 depicts an elongated flexible tubular member 320 and a first and second connecting member 340 and a second connecting member 350, both extending through a lumen within the tubular member 320. Figures 6–8 depict merely illustrative embodiments of the proximal end 330 of an implant subassembly, which is sized and configured to be advanced into a handle subassembly and locked in place during a medical procedure. In this particular exemplary embodiment, the first connecting member 340 (one embodiment of which is shown in Figure 5) connects to a detachable component 370 of the proximal end 330 of the implant subassembly 300. The second connecting member 350 (one embodiment of which is shown in Figure 5) connects to a static component 360 of the proximal end 330 of the implant subassembly 300. Preferably, the second connecting member 350 is fixed to the static component 360 while under tension. The second connecting member 350 can be fixed or connected to the static component 360 in a variety of ways, such as by bonding, adhesive(s), or one or more of other common connecting techniques. In this exemplary embodiment, the second connecting member 350 serves to fix the first connecting member 340 in such a way that it locks the implant to the delivery system until the first connecting member 340 is pulled proximal to release the implant. Figure 8 shows a perspective cross-sectional view showing that the first connecting member 340 extends through and is connected to the static component 360 and the detachable component 370. The first connecting member 340 is fixed to the detachable component 370 such that when the detachable component 370 is moved in the proximal direction, the first connecting member 340 is also moved in the proximal direction (and relative to the static component 360 which does not move axially) to release the implant from the delivery system.
[0057]
[0067] One aspect of the present disclosure is a handle subassembly including an implant subassembly locking mechanism positioned and adapted to lock the proximal end of the implant subassembly within the handle after the implant subassembly has been moved proximal through a handle tubular member into the handle during a medical procedure to deploy an implant. The implant subassembly locking mechanism may be adapted to be actuated by a user to lock the proximal end of the implant subassembly within the handle, one embodiment of which is described in relation to Figures 6-8.
[0058]
[0068] In some exemplary embodiments, the handle subassembly may further include an implant subassembly stopper at least partially located within the handle, the implant subassembly stopper positioned within the handle to contact the proximal end of the implant subassembly and to stop the proximal end of the implant subassembly from moving further proximal, and the stopper is positioned so as to activate an implant subassembly locking mechanism to lock the proximal end of the implant subassembly within the handle. The implant subassembly stopper would offer the advantage of automatically stopping the implant subassembly at a specific location within the handle such that the locking process is simple and can be successfully performed by user operation of a lock actuator, which will be described in more detail later. Figure 8 illustrates an exemplary stopper 295 having a distal end positioned and configured to stop the proximal movement of the implant subassembly at a specific location. Here, either of the stoppers can also function as a safety release member that must be removed from the handle before the implant is released. For example, the stopper and safety release mechanism can interact with the handle such that the connecting member 340 cannot be physically pulled in the proximal direction until the stopper / safety member is removed from the handle.
[0059]
[0069] In the exemplary embodiments shown in Figures 6-8, the implant subassembly locking mechanism of the handle subassembly includes a lock actuator 280 (see also Figure 1) positioned and adapted to the handle housing 212 to be operated by the user to lock the proximal end 330 of the implant subassembly into the handle after the implant subassembly has been moved proximal through the elongated tubular member of the handle into the handle during a medical procedure to implant the implant. The implant subassembly locking mechanism includes first and second locking elements 282 and 284 positioned and configured to act radially inward toward the proximal end 330 of the implant subassembly when the lock actuator 280 is actuated (for example, when a handle button is pressed down). The first and second locking elements 282 and 284 are positioned and configured to move radially inward when the lock actuator 280 is actuated, and to contact the static component 360 and the detachable component 370, respectively, to lock the proximal end 330 in place relative to the handle.
[0060]
[0070] In this particular embodiment, which is merely illustrative, the locking elements 282 and 284 are configured as clips, and each locking element has a surface configured to lock into contact with the outer surfaces of axially spaced regions 362 and 372, respectively, on the static component 360 and the detachable component 370. In this non-limiting embodiment, the axially spaced regions 362 and 372 each have a smaller outer dimension than the axially adjacent region, and the smaller outer dimension conforms the regions 362 and 372 to lock into place relative to the handle. In this embodiment, the regions 362 and 372 can be considered to have recesses on their outer surfaces configured to lock into place relative to the handle of the handle subassembly. In an alternative embodiment, the locking actuator may be unnecessary by having both locking elements 282 and 284 in different spring-loaded configurations so that when the implant subassembly is introduced into the handle subassembly, the fork portion 282 slides over region 372 and then the fork portion 284 drops into region 372. Alternative configurations are conceived. For example, the locking element could be configured as a modulated throttling that closes radially into regions 362 and 372, with the modulation automatically triggered when the proximal end 330 of the implant subassembly passes the handle, thus eliminating the need for a locking actuator. In other embodiments, bosses may be provided to drop into slots in the static component 360 and the detachable component 370. The bosses may or may not be cam-shaped.
[0061]
[0071] As described above, the detachable component 370 to which the first connecting member 340 is fixed is adapted to move proximal to the static component 360 within the handle to retract the first connecting member 340 and release the implant. The detachable component 370 is connected to region 372 such that the detachable component 370 and region 372 move proximal together as a unit. The static component 360 is connected to region 362 such that the static component 360 and region 362 remain stationary together as a unit when the detachable component is pulled proximal. Figure 6 shows the separation point 361 where the detachable component 370 separates from the static component 360. In one embodiment, this is achieved by acting on a handle release actuator 260 (see Figure 1), which is operably in communication with the detachable component 370 via a locking element 284. As shown in Figure 8, the locking element 284 is fixed within a threaded member 290 that is screwed into the handle release actuator 260. When the handle release actuator 260 (not shown in Figure 8) is activated (e.g., rotated), the threaded member 290 is moved axially by its screw relationship, and the handle release actuator 260 is fixed in a predetermined position axially (but can rotate). The axial movement of the threaded member 290 similarly moves the locking element 284 axially. The locking element 284 is locked to a detachable component 370 connected to a first connecting member 340. This exemplary arrangement causes proximal movement of the first connecting member 340, thereby releasing the implant. The activation of the handle release actuator 260 therefore causes the release of the implant. This disclosure therefore describes a modular pre-loaded implant that can be locked in a predetermined position relative to a handle during a medical procedure, and moreover, a modular pre-loaded implant in which the implant connecting member can be moved relative to the handle to facilitate the release of the implant when desired.
[0062]
[0072] The locking element 282 is not located within the screw member 290, and therefore does not move proximal together with the locking element 284 when the handle release actuator 260 is activated. Thus, this configuration is one embodiment of how to prevent static members from moving when a detachable member needs to be moved to release the implant.
[0063]
[0073] The following disclosures illustrate exemplary procedure steps that may be performed during implant linking and delivery. Some of these procedure steps are described above. Not all of the following procedure steps are necessarily required, and one or more steps may actually be for illustrative purposes and / or optional.
[0064]
[0074] One aspect of the present disclosure is a method for assembling an implant subassembly and a handle subassembly. The method may include the step of removing an implant subassembly (e.g., 300) from a first package (e.g., 500), the implant subassembly comprising a proximal end and a folded implant in a cartridge. The method may further include the step of removing a handle subassembly (e.g., 200) from a second package (e.g., 400), the handle subassembly comprising a handle and an elongated handle tubular member operably communicating with a handle actuator (e.g., 214), the operation of which causes axial movement of the elongated handle tubular member. The method may further include the step of advancing the proximal end of the implant subassembly into the distal end of the elongated handle tubular member, through the elongated handle tubular member, into the handle of the handle subassembly. The method may further include the step of locking the proximal end of the implant subassembly in a predetermined position relative to the handle subassembly.
[0065]
[0075] Once the implant subassembly is locked in place relative to the handle, the locked system is in the configuration shown in Figure 9, with the implant tubular member 320 (not visible) located within the handle tubular member 250 and the handle 210. The distal end of the handle tubular member 250 is located immediately proximal to the implant (not visible) in the cartridge. The handle tubular member 250 may be much longer than shown in Figure 9, and the two curves suggest the length of a tubular member 250 that is not shown.
[0066]
[0076] Figure 10 depicts implant 600 in a deployed and optionally curved configuration; however, Figure 10 only shows the relative position of implant 600 within cartridge 310 as an example. Any of the implants in this specification may be non-deployable implants, but they will still be pre-loaded into a cartridge or other elongated housing. Thus, the term cartridge in this specification may be broadly replaced with a more general term such as an elongated housing having a lumen inside, and the cartridge may be rigid.
[0067]
[0077] In some exemplary embodiments, the distal end of the cartridge may then be connected to the proximal end 902 of the delivery catheter 900, one example of which is shown in Figure 11. The distal end 904 of the catheter is also shown. In some exemplary embodiments, the delivery catheter 900 may have a length of 50 to 90 cm, for example, 60 to 80 cm.
[0068]
[0078] Figure 12 illustrates an example of a Luer lock connection between the cartridge and the delivery catheter (after the handle subassembly and implant have been advanced through the delivery catheter).
[0069]
[0079] After the cartridge is connected to the delivery catheter 900, the handle subassembly 200, the handle tubular member 250, the implant tubular member 320, and the implant are advanced distally to the cartridge until the handle contacts the cartridge, as shown in Figure 12. The male thread of the cartridge is configured to engage with the female thread of the delivery catheter control actuator 265, so that once engaged, the operation of the actuator 265 controls the axial movement of the cartridge and the delivery catheter connected to the cartridge at this point. Now that the implant is positioned within the delivery catheter at its distal end, the axial movement of the cartridge and the delivery catheter allows for the implant to be sheathed and re-sheathed as needed. After the implant has been deployed from the delivery catheter, which may occur by moving the delivery catheter relative to the implant, the implant may be released. To allow the implant to be released, a safety member (which may also be a stopper as described herein) as shown at the proximal end of the handle in Figure 9 may be removed. As described in more detail above, the release actuator 260 can be activated to move the locking member 284 proximal, causing proximal movement of the detachable component 370 and the first connecting member 340, thereby releasing the implant. The delivery system may then be removed.
[0070]
[0080] As shown above, the step of advancing the proximal end of the implant subassembly into the handle may further include the step of advancing the proximal end of the implant subassembly until it engages with an implant subassembly stopper (e.g., 295) within the handle.
[0071]
[0081] The step of locking the proximal end of the implant subassembly against the handle subassembly may include moving a locking element (e.g., 284) to a locked position relative to the proximal end of the implant subassembly. The locking element may be moved until it engages with a detachable component (e.g., 370) of the implant subassembly, the detachable component being fixed to a first connecting member (e.g., 340) of the implant subassembly, the first connecting member portion of the connecting mechanism being connected to the implant (e.g., 600) in a first state, and the first connecting member being movable relative to the implant to release the implant. The step of locking the proximal end of the implant subassembly against the handle subassembly may further include moving a second locking element (e.g., 282) until it engages with the proximal end of the implant subassembly and optionally until it engages with a static component (e.g., 360) of the implant subassembly. The static components may be connected to a second connecting member (e.g., 350) of the coupling mechanism, and the second locking element and the second connecting member are not axially movable after being locked in place relative to the handle.
[0072]
[0082] The step of locking the proximal end of the implant subassembly may include the step of activating (optionally pushing down) a handle lock actuator (e.g., 280), although other types of actuators may be used.
[0073]
[0083] At a point in time following the step of locking the proximal end of the implant subassembly, any of the methods herein may further include the steps of delivering the implant to a target location and releasing the implant. The releasing step may include acting a release handle actuator (e.g., 260) to cause movement of a detachable component (e.g., 370) at the proximal end of the implant subassembly, which is fixed to an implant coupling member (e.g., 340).
[0074]
[0084] Next, the entire delivery system may be removed from the patient, leaving the implant embedded in the target location. [Explanation of symbols]
