Abstract

An implantable inflatable penile prosthesis cylinder has a longitudinal axis and includes an inflatable portion. The inflatable portion includes a chamber that defines an inflatable chamber. The chamber wall includes at least one thin wall section and at least one thick wall section. The at least one thin wall section stretches a greater amount than the at least one thick wall section in a plane extending perpendicular to the longitudinal axis when the inflatable chamber is transitioned from a deflated state to an inflated state.

First claim

What is claimed is:

1 . An implantable inflatable penile prosthesis cylinder having a longitudinal axis and comprising an inflatable portion including a chamber wall defining an inflatable chamber, the chamber wall comprising at least one thin wall section and at least one thick wall section, wherein the at least one thin wall section stretches a greater amount than the at least one thick wall section in a plane extending perpendicular to the longitudinal axis when the inflatable chamber is transitioned from a deflated state to an inflated state.

2 . The inflatable penile prosthesis cylinder according to claim 1 , wherein the chamber wall includes a plurality of the thin wall sections and a plurality of the thick wall sections, wherein each of the thick wall sections is disposed between a pair of the thin wall sections in a plane extending perpendicularly to the longitudinal axis.

3 . The inflatable penile prosthesis cylinder according to claim 2 , wherein the thin wall sections are angularly displaced from each other about the longitudinal axis.

4 . The inflatable penile prosthesis cylinder according to claim 3 , wherein the thin wall sections are uniformly angularly distributed from each other about the longitudinal axis.

5 . The inflatable penile prosthesis cylinder according to claim 3 , wherein the thin wall sections are non-uniformly angularly distributed from each other about the longitudinal axis.

6 . The inflatable penile prosthesis cylinder according to claim 1 , wherein the at least one thin wall section has a thickness of less than 0.020 inches, and the at least one thick wall section has a thickness of greater than 0.020 inches.

7 . The inflatable penile prosthesis cylinder according to claim 2 , wherein the thin wall sections extend along the longitudinal axis.

8 . The inflatable penile prosthesis cylinder according to claim 2 , wherein the thin wall sections and the thick wall sections are formed of the same material.

9 . The inflatable penile prosthesis cylinder according to claim 8 , wherein the thin wall sections and the thick wall sections are formed of silicone.

10 . The inflatable penile prosthesis cylinder according to claim 1 , further comprising a plurality of inflatable chamber sections within the inflatable chamber, wherein inflation of the plurality of inflatable chamber sections transitions the inflatable chamber to the inflated state.

11 . The penile prosthesis cylinder according to claim 2 , further comprising a fluid reservoir and fluid pathways connecting the fluid reservoir to the inflatable chamber.

12 . An implantable penile prosthesis comprising:
a pair of inflatable penile prosthesis cylinders, each penile prosthesis cylinder having a longitudinal axis and comprising an inflatable portion including a chamber wall defining an inflatable chamber, the chamber wall comprising at least one thin wall section and at least one thick wall section; a reservoir containing fluid; and an inflation apparatus configured to transfer fluid from the reservoir into the inflatable chamber to transition the inflatable portion to an inflated state; wherein the at least one thin wall section stretches a greater amount than the at least one thick wall section in a plane extending perpendicular to the longitudinal axis when the inflatable chamber is transitioned from a deflated state to the inflated state.

13 . The implantable penile prosthesis according to claim 12 , wherein the chamber wall includes a plurality of the thin wall sections and a plurality of the thick wall sections, wherein each of the thick wall sections is disposed between a pair of the thin wall sections in a plane extending perpendicularly to the longitudinal axis.

14 . The implantable penile prosthesis according to claim 13 , wherein the thin wall sections are angularly displaced from each other about the longitudinal axis.

16 . The implantable penile prosthesis according to claim 14 , wherein the thin wall sections are uniformly angularly distributed from each other about the longitudinal axis.

17 . The implantable penile prosthesis according to claim 14 , wherein the thin wall sections are non-uniformly angularly distributed from each other about the longitudinal axis.

18 . The implantable penile prosthesis according to claim 12 , wherein the at least one thin wall section has a thickness of less than 0.020 inches, and the at least one thick wall section has a thickness of greater than 0.020 inches.

19 . The implantable penile prosthesis according to claim 13 , wherein the thin wall sections extend along the longitudinal axis.

20 . The implantable penile prosthesis according to claim 12 , further comprising a plurality of inflatable chamber sections within the inflatable chamber, wherein inflation of the plurality of inflatable chamber sections transitions the inflatable chamber to the inflated state.
