Abstract
Abstract A technique for the treatment of male impotence. The apparatus to be implanted in the corpus cavernosum of the penis is a cylinder of an implantable polymer. The cylinder is generally flexible and has a plurality of transitions from a lesser diameter to a greater diameter. As the cylinder is filled with fluid under pressure, the areas of lesser diameter tend to expand, thereby effectively lengthening the cylinder without an unacceptable increase in girth. Optional rings may be positioned over the areas of lesser diameter to prevent collapse. An optional outer sheath also improves longitudinal stability.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
115 words
An implantable penile prosthesis comprising: a. a hollow inner cylinder of a flexible biocompatible material having an outer surface forming a plurality of smooth sinusoidal transitions from a minimum diameter to a maximum diameter in both a flaccid and a pressurized state, said plurality of sinusoidal transitions occupying a majority of the outer surface area of said inner cylinder; b. a base mount sealingly attached to one end of said inner cylinder; c. a source of pressurized fluid in fluid communication with said inner cylinder for pressurizing said inner cylinder; and d. at least one ring member configured for attaching to said minimum diameter of at least one of said plurality of smooth sinusoidal transitions.
Claim 2
Dependent Claim
115 words
