[0002] This application also claims priority to U.S. Provisional Patent Application No. 63/512,146, filed on July 6, 2023, the disclosure of which is incorporated by reference herein in its entirety'.

TECHNICAL FIELD

[0003] This disclosure relates generally to devices for insertion of bodily implants and, more specifically, to disposable insertion devices for bodily implants, such as penile prostheses.

BACKGROUND

[0004] One treatment for chronic, organic, male erectile dysfunction is the implantation of a penile prosthesis that mechanically erects the penis. Such prostheses can have different physical constructions (e.g., materials, mechanical structure and function, etc.) and configurations (e g., physical dimensions, etc.). For instance, such a penile prosthesis can be in the form of a cylinder (e.g., malleable, inflatable, etc.) that is selected based on the physical requirements of an intended recipient (a patient). For instance, an appropriate penile prosthesis can be implanted within a corpus cavemosum (corpus cavernosa) of a patient’s penis by medical personnel that are trained and knowledgeable regarding the implantation and use of penile prostheses. [0005] Insertion devices (e.g., Furlow insertion devices) can be used to facilitate the insertion of a penile prosthesis into the corpus cavemosum of a patient. Such Furlow insertion devices can be used for measurement of an insertion length within the corpus cavernosum, as well as for facilitating insertion of a penile prosthesis by deploying a suture-carrying needle, where the needle and/or suture are used to introduce (draw, pull, insert, implant, etc.) the prosthesis into the corpus cavemosum.

SUMMARY

[0006] According to a general aspect, an insertion device includes an elongate member defining a lumen extending from a first end of the elongate member to a second end of the elongate member, and a pusher having a first end portion. The first end portion of the pusher is configured to be disposed within the lumen defined by the elongate member and move from a first position within the lumen defined by the elongate member to a second position within the lumen defined by the elongate member. The first end portion of the pusher defines a slot.

[0007] In some implementations, the first end portion of the pusher defines a receiving portion. In some implementations, the first end portion of the pusher defines a receiving portion configured to receive a portion of a needle.

[0010] In some implementations, the first end portion of the pusher is configured to be placed in an expanded configuration and a collapsed configuration. In some implementations, the first end portion of the pusher is configured to be placed in an expanded configuration and a collapsed configuration, the first end portion of the pusher being configured to be placed in the collapsed configuration in response to the first end portion of the pusher contacting an inner diameter of the elongate member.

[0011] In some implementations, the first end portion of the pusher includes a first section disposed on a first side of the slot and a second section disposed on a second side of the slot, the first end portion of the pusher is configured to be placed in an expanded configuration and a collapsed configuration, the first section of the pusher being disposed closer to the second section of the pusher when the first end portion of the pusher is disposed in the collapsed configuration than when the first end portion of the pusher is disposed in the expanded configuration.

[0012] In some implementations, the elongate member defines a slot.

[0013] According to another aspect, a kit includes a bodily implant; a delivery needle configured to be coupled to the bodily implant: and a delivery device having an elongate member defining a lumen extending from a first end of the elongate member to a second end of the elongate member, and a pusher having a first end portion, the first end portion of the pusher being configured to be disposed within the lumen defined by the elongate member and move from a first position within the lumen defined by the elongate member to a second position within the lumen defined by the elongate member, the first end portion of the pusher defining a slot.

[0014] In some implementations, the elongate member defines a slot configured to receive at least a portion of the delivery needle. In some implementations, the slot defined by the first end portion of the pusher extends in a direction parallel to a longitudinal axis of the pusher. In some implementations, the slot defined by the first end portion of the pusher is a first slot, the first end portion of the pusher defining a second slot. In some implementations, the slot defined by the first end portion of the pusher is a first slot, the first end portion of the pusher defining a second slot, the first slot extends in a direction parallel to a longitudinal axis of the pusher, the second slot extends is a direction parallel to the longitudinal axis of the pusher. In some implementations, the first end portion of the pusher defines a plurality of slots.

For example, such insertion devices can be configured to be used in a single procedure and then discarded or disposed of. Some such insertion devices may have components that are coupled together and that when removed from each other would destroy the insertion device.

[0034] FIG. 1 schematically illustrates a system according to an implementation. The system includes a delivery or insertion device 100, an implant 195, and a needle 190 coupled to the implant 195. In some implementations, the implant 195 may be a penile implant or another type of implant that is configured to be placed in the pelvic region of the patient. In other implementations, the implant 195 is configured to be placed within the body of the patient at a different location. In some implementations, the needle 190 is coupled to the implant 195 via a suture. In other implementations, the needle 190 is directly coupled to the implant 195 or is coupled to the implant 195 via another mechanism.

[0035] The insertion device 100 includes an elongate member 110, a coupler 140, and a pusher or an obturator 170. The elongate member 110 is coupled to the coupler 140 and the pusher or obturator 170 is coupled to the coupler 140. In some implementations, the elongate member 110 is fixedly coupled to the coupler 140. In some implementations, the obturator 170 is moveably, such as slidably, coupled to the coupler 140. The pusher or obturator 170 has a portion that is configured to be disposed within a lumen defined by the elongate member 110.

[0036] In use, the needle 190 or a portion of the needle 190 may be placed or disposed within the lumen defined by the elongate member. The delivery device 100 including the needle 190 may be placed within the body of the patient to a desired location. The pusher or obturator 170 may then be advanced or moved distally within the lumen defined by the elongate member 110. The pusher or obturator 170 is configured to engage the needle 190 and advance the needle 190 out of the lumen defined by the elongate member 110. The delivery device 100 may then be removed from the body of the patient and the needle can then be pulled or otherwise moved within the body of the patient until the implant 195 is disposed at a desired location.

[0037] FIGS. 2-6 illustrate an insertion device 200 according to an implementation. FIG. 2 is a perspective view of the insertion device 200. FIGS. 3 and 4 are cross-sectional views of the insertion device. FIGS. 5 and 6 are cross sectional views of a portion of the insertion device. [0038] The insertion device 200 includes an elongate member 210, a coupler 240, and a pusher or obturator 270. The elongate member 210 is coupled to the coupler 240 and the pusher or obturator 270 is coupled to the coupler 240. In the illustrated implementation, the elongate member 210 is fixedly coupled to the coupler 240.

[0039] As best illustrated in FIG. 3-6, the coupler 240 defines a lumen 242. A proximal end portion 212 of the elongate member 210 is configured to be disposed within the lumen 242 defined by the coupler 240. The proximal end portion 212 of the elongate member 210 includes an engagement portion or engagement member 217. The engagement portion or member 217 extends from an outer surface 211 of the elongate member 210. The coupler 240 also includes an engagement member 244. The engagement member 244 of the coupler 240 extends into the lumen 242 defined by the coupler 240. The engagement member 244 of the coupler 240 is configured to engage or interact with the elongate member 210 to couple the elongate member 210 to the coupler 240. As best illustrated in FIG. 6, the engagement member 244 of the coupler 240 is configured to engage or interact with the engagement member 217 of the elongate member 210. In some implementations, the engagement member 244 of the coupler 240 is configured to bend or flex to provide a snap type coupling to the elongate member 210. In other implementations, the elongate member 210 is coupled to the coupler via a different mechanism or different ty pe of coupling.

[0040] As best illustrated in FIGS. 3-5, in the illustrated implementation, the pusher or obturator 270 is movably coupled to the coupler 240. At least a portion of the pusher or obturator 270 is disposed within the lumen 242 defined by the coupler 240 and is configured to slide, translate, or otherwise move with respect to the coupler 240. In the illustrated implementation, the coupler 240 includes an engagement member 246. As will be discussed in more detail below, the engagement member 246 extends into the lumen 242 defined by the coupler 240 and is configured to engage or contact a portion of the pusher or obturator 270.

[0041] At least a portion of the pusher or obturator 270 extends into a lumen 216 defined by the elongate member 210. The pusher or obturator 270 is configured to slide or otherwise move within the lumen 216 defined by the elongate member 210. [0042] In use, a needle that is coupled to a bodily implant may be placed or disposed within the lumen 216 defined by the elongate member 210. The delivery device 200 including the needle may be placed within the body of the patient to a desired location. The pusher or obturator 270 may then be advanced or moved distally within the lumen 216 defined by the elongate member 210. The pusher or obturator 270 is configured to engage the needle and advance the needle out of the lumen 216 defined by the elongate member 210. The delivery device 200 may then be removed from the body of the patient and the needle can then be pulled or otherwise moved within the body of the patient until the implant is disposed or located at a desired location.

[0043] FIGS. 7 and 8 illustrate the elongate member 210. The elongate member 210 includes or defines a slot 218. The slot 218 is disposed at the distal end portion 214 of the elongate member 210 and communicates with the lumen 216 defined by the elongate member 210. The slot 218 is configured to receive the needle to facilitate the placement of the needle into the lumen 216 defined by the elongate member 210. The elongate member 210 also includes a tapering or tapered portion 213 of the lumen 216 at the distal end portion 214 of the elongate member 210. In some implementations, the tapering or narrowing of the lumen 216 (the inner diameter of the lumen gets smaller towards the end of the elongate member 210) helps eject or dispose of the needle more accurately as desired by the user. For example, the narrowing or tapering of the lumen 216 of the elongate member 210 may limit the or minimize the exit angle of the needle from the lumen 216.

[0044] In the illustrated implementation, the elongate member 210 includes a handle portion 215. The handle portion 215 extends from an outer surface 21 1 of the elongate member 210. The handle portion 215 may be grasped by the user during the insertion of the delivery' device 200 into the body of the patient and during the advancement or movement of the pusher or obturator 270 with respect to the elongate member 210.

[0045] The elongate member 210 includes measurement markings 219. The measurement markings 219 may be configured to indicate to the user how far the elongate member 210 (or the delivery device 200) has been inserted into the body of the patient. In some implementations, the measurement markings 219 are laser etched onto the material of the elongate member 210. In such implementations, the surface of the elongate member 210 that includes the measurement markings 219 may be smooth. In other implementations, the measurement markings 219 may be formed in a different manner. For example, the measurement markings 219 may be painted, colored, or otherwise marked on the surface of the elongate member 210.

[0046] FIGS. 9 and 10 illustrate the coupler 240. In the illustrated implantation, the coupler 240 defines a lumen 242. The lumen 242 is configured to receive at least a portion of the elongate member 210 and at least a portion of the obturator 270. The coupler includes an engagement member 244 that is configured to engage the elongate member 210 to couple the elongate member 210 to the coupler 240. The engagement member 244 extends into the lumen 242 defined by the coupler 240. In some implementations, the engagement member 244 is configured to bend or flex.

[0047] The coupler includes an engagement member 246. The engagement member 246 extends into the lumen 242 defined by the coupler 240 and is configured to engage the pusher or obturator 270. In some implementations, the engagement member 246 is configured to contact or engage the pusher or obturator 270 to help prevent the pusher or obturator 270 from being removed from the coupler 240. Accordingly, the pusher or obturator 270 may move or slide within the lumen 242 defined by the coupler 240 but in some implementations, may not be removed entirely from the lumen 242 of the coupler 240.

[0048] In the illustrated implementation, the coupler 240 includes ridges or projections 248 that extend from an outer surface of the coupler 240. The ridges or projections 248 may facilitate the grasping or gripping of the coupler 240 or the delivery device 200 during use of the device.

[0049] FIGS. 11 and 12 illustrate the pusher or obturator 270 of the delivery⁷ device 200. The pusher or obturator 270 includes a distal end portion 276 and a handle portion disposed opposite the distal end portion 276. The pusher or obturator 270 includes ramps or bumps 272 A and 272B. The ramps or bumps extend from an outer surface 271 of the obturator 270 and are configured to engage the coupler 240. For example, in some implementations, the ramps or bumps 272A and 272B are configured to engage the engagement member 246 of the coupler 240. For example, in the illustrated implementation, the proximal ramps 272A may engage the engagement member 246 of the coupler 240 when the pusher or obturator 270 is placed in its distal most position. The distal ramp 272B may be configured to engage the engagement member 246 of the coupler 240 when the obturator is placed in its proximal most position. Additionally, in some implementations, the distal ramps 272B may engage the engagement member 246 of the coupler 240 to help prevent the removal of the pusher or obturator 270 from the coupler 240.

[0050] In the illustrated implementation, the pusher or obturator 270 includes an association ramp or bump 274. The association ramp or bump 274 is configured to facilitate the association of the pusher or obturator 270 and the coupler 240 and is configured to help prevent the removal of the pusher or obturator 270 from the coupler 240. For example, in some implementations, the association ramp or bump 274 is configured to contact or engage the coupler 240 to prevent the removal or disassociation of the pusher or obturator 270 from the coupler 240.

[0051] The distal end 276 of the pusher or obturator 270 defines a series or slots 273. The slots 273 extend longitudinally. In other words, the slots 273 extend in a direction parallel to a longitudinal axis LA of the pusher or obturator 270. In the illustrated implementation, the pusher or obturator 270 defines six slots. In other implementations, the pusher or obturator 270 defines more than six slots. For example, the distal end portion 276 may define 8, 10, 12 or more slots. In yet other implementations, the pusher or obturator 270 may define less than six slots. For example, the distal end portion 276 may define 1, 2, 3, 4, or 5 slots.

[0052] The slots 273 defined by the distal end portion 276 of the pusher or obturator 270 allow the distal end portion 276 of the pusher or obturator 270 to be placed in an expanded configuration and a collapsed configuration. For example, in some implementations, the portions of the pusher or obturator 270 that are disposed adjacent to the slots 273 are configured to flex or bend to allow the outer diameter or other size of the distal end portion to become smaller. In some implementations, when the other surface of the pusher or obturator 270 contacts an inner surface of the elongate member 210, the pusher or obturator 270 may be moved into its contracted or collapsed configuration. In some implementations, portions of the elongate member 210 may have a slightly larger or a slightly smaller inner diameter. These variations may be due to manufacturing processes or due heating and expansion or contraction after the manufacturing process. [0053] As the distal end portion 276 of the pusher or obturator 270 is configured to expand and collapse, the distal end portion 276 of the pusher or obturator 270 can accommodate small changes in the inner diameter of the elongate member 210. Accordingly, as the pusher or obturator 270 is moved within the lumen defined by the elongate member 210 the pusher or obturator 270 may move smoothly even if the inner diameter of the elongate member 210 varies.

[0054] FIG. 13 is a side view of the insertion device 200. FIG. 14 is a cross- sectional view of the insertion device taken along line A-A of FIG. 13. FIG. 15 is a cross-sectional view of the insertion device taken along line B-B of FIG. 13. As best illustrated in FIG. 14, the distal end portion 276 of the pusher or obturator 270 can assume an expanded configuration (larger outer diameter and larger spaces between the portions that are adjacent to the slots) when the distal end portion 276 of the pusher or obturator 270 is located at a location of a larger inner diameter of the elongate member 210. As illustrated in FIG. 15, the distal end portion 276 of the pusher or obturator 270 can assume a collapsed or compressed configuration (smaller outer diameter and smaller spaces between the portions that are adjacent to the slots) when the distal end portion 276 of the pusher or obturator 270 is located at a location of a smaller inner diameter of the elongate member 210.

[0055] FIGS. 16 to 18 illustrate steps for placing an implant within a body of a patient using a delivery device. As illustrated in FIG. 16, a needle 290 may be associated with or coupled to an implant 195. In some cases, the needle 290 may be associated with the implant 195 via a suture. As illustrated in FIG. 17, the needle 290 may be placed within the lumen defined by the elongate member 210 of the delivery device 200. In some cases, the needle 290 may be inserted into the lumen via a slot defined by the elongate member 210. As illustrated in FIG. 18, the delivery' device 200 may be inserted into the body of the patient, such as into a penis P of the patient. Once the delivery device 200 including the needle 290 are placed within the body of the patient at a desired location, the pusher or obturator 270 may then be advanced or moved distally within the lumen defined by the elongate member 210. The pusher or obturator 270 is configured to engage the needle 290 and advance the needle 290 out of the lumen defined by the elongate member 210. The delivery device 200 may then be removed from the body of the patient and the needle 290 can then be pulled or otherwise moved within the body of the patient until the implant 295 is disposed at a desired location.
