Abstract

According to an aspect, an implant includes an inflatable member and a pump assembly configured to facilitate a transfer of a fluid from the reservoir to the inflatable member. The inflatable member has a sidewall that defines a lumen. The sidewall has an outer surface and an inner surface disposed opposite the outer surface. The inner surface has a series of undulations.

First claim

What is claimed is:

1. An implant, comprising:
an inflatable member; and
a pump assembly configured to facilitate a transfer of a fluid from a reservoir to the inflatable member,
the inflatable member having a sidewall that defines a lumen, the sidewall having an outer surface and an inner surface disposed opposite the outer surface, the sidewall being formed of a material, the material extending from the inner surface to the outer surface, the inner surface having a series of undulations such that the lumen defined by the sidewall of the inflatable member includes a first portion having a first diameter, a second portion having a second diameter, and a third portion having a third diameter, the second portion being disposed between the first portion and the third portion along a longitudinal axis of the inflatable member, the second diameter begin larger than the first diameter, the second diameter being larger than the third diameter, the sidewall having the first portion having a first thickness and the second portion having a second thickness, the second thickness being smaller than the first thickness.

2. The implant of claim 1 , wherein the outer surface of the inflatable member is substantially smooth.

3. The implant of claim 1 , wherein the outer surface of the inflatable member includes a series of undulations.

4. The implant of claim 1 , wherein the inflatable member is unitarily formed.

5. The implant of claim 1 , wherein the inflatable member is configured to be placed in an inflated configuration and a deflated configuration, the inflatable member having a tubular shape when in the deflated configuration.

6. The implant of claim 1 , wherein the inflatable member is configured to be placed in an inflated configuration and a deflated configuration, the inflatable member configured to extend along a longitudinal axis when placed in the inflated configuration.

7. The implant of claim 1 , further comprising:
a first cap coupled to a first end portion of the inflatable member; and
a second cap coupled to a second end portion of the inflatable member.

8. The implant of claim 1 , further comprising:
a reservoir configured to retain the fluid,
wherein the pump is configured to help facilitate a transfer of the fluid from the reservoir to the inflatable member when the implant is in an inflation mode.

9. The implant of claim 1 , wherein the pump assembly includes a valve body and a pump bulb member.

10. A method of making an elongate member of a penile implant, comprising:
forming a core member having a longitudinal axis and an outer surface, the outer surface having a series of undulations;
disposing the core member within a lumen of a casing;
placing material between the core member and the casing before the removing of the core member to form the elongate member such that the inner surface has a series of undulations and a lumen defined by the sidewall of the elongate member includes a first portion having a first diameter, a second portion having a second diameter, and a third portion having a third diameter, the second portion being disposed between the first portion and the third portion along a longitudinal axis of the inflatable member, the second diameter being larger than the first diameter, the second diameter being larger than the third diameter, the first portion of the elongate member has a first thickness and the second portion of the elongate member has a second thickness, the second thickness being smaller than the first thickness; and
removing the core member from the casing.

11. The method of claim 10 , wherein the core member is formed of a material that is configured to dissolve.

12. The method of claim 10 , wherein the removing the core member from the casing includes dissolving the core member.

13. An implant, comprising:
an inflatable member; and
a pump assembly configured to facilitate a transfer of a fluid from a reservoir to the inflatable member,
the inflatable member being unitarily formed and having a sidewall that defines a lumen, the sidewall having an outer surface and an inner surface disposed opposite the outer surface, the sidewall being formed of a solid material extending from the inner surface to the outer surface, the inner surface having a series of undulations such that the lumen defined by the sidewall of the inflatable member includes a first portion having a first diameter, a second portion having a second diameter, and a third portion having a third diameter, the second portion being disposed between the first portion and the third portion along a longitudinal axis of the inflatable member, the second diameter begin larger than the first diameter, the second diameter being larger than the third diameter, the outer surface being substantially smooth.

14. The implant of claim 13 , wherein the inflatable member is configured to be placed in an inflated configuration and a deflated configuration, the inflatable member having a tubular shape when in the deflated configuration.

15. The implant of claim 13 , wherein the inflatable member is configured to be placed in an inflated configuration and a deflated configuration, the inflatable member configured to extend along a longitudinal axis when placed in the inflated configuration.

16. The input of claim 13 , further comprising:
a first cap coupled to a first end portion of the inflatable member; and
a second cap coupled to a second end portion of the inflatable member.

17. The implant of claim 13 , further comprising:
a reservoir configured to retain the fluid,
wherein the pump is configured to help facilitate a transfer of the fluid from the reservoir to the inflatable member when the implant is in an inflation mode.

18. The implant of claim 13 , wherein the pump assembly includes a valve body and a pump bulb member.

19. The implant of claim 1 , wherein the first portion extends from a first location along the longitudinal axis to a second location along the longitudinal axis.

20. The implant of claim 13 , wherein the first portion extends from a first location along the longitudinal axis to a second location along the longitudinal axis.
