Abstract A penile prosthesis includes at least one and preferably a pair of penile implants. The penile implant is a flexible, elongated member having a short proximal stem which is hollow and includes a fluid filled reservoir. The stem is adapted to be implanted into the root end of the corpus cavernosum to support the implant. The flexible member also includes an elongated flexible, non-distensible distal portion having a chamber substantially filled with a non-compressible fluid and a conical tip and an intermediate fluid filled pressure bulb pump which includes a valve mechanism. The valve mechanism allows fluid to be pumped from the reservoir in the stem into the non-distensible chamber to pressurize it and make it rigid. The implant includes a pressure relief valve which allows fluid to be transferred back to the reservoir.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
A penile implant comprising a flexible, elongated member having a relatively short, hollow, proximal stem, said stem having a wall portion which is relatively stiff so as to support and anchor the implant and a reservoir for inflating fluid; an elongated flexible distal portion having a non-distensible, pressurizable chamber and a tip and pump means located within said elongated member between the reservoir in the hollow stem and the pressurizable chamber for transferring fluid from the reservoir to the non-distensible chamber.
Claim 2
Dependent Claim
81 words
A penile implant comprising a flexible, elongated member having a relatively short, hollow, proximal stem, said stem having a wall portion which is relatively stiff so as to support and anchor the implant and a reservoir for inflating fluid; an elongated flexible distal portion having a non-distensible, pressurizable chamber and a tip and pump means located within said elongated member between the reservoir in the hollow stem and the pressurizable chamber for transferring fluid from the reservoir to the non-distensible chamber.
Claim 3
Dependent Claim
15 words
The penile implant of claim 1 in which the pump means is a pressure bulb.
Claim 4
Dependent Claim
33 words
The penile implant of claim 1 in which the pump means includes valve means which allow fluid to be transferred from the reservoir to the pump and from there to the pressurizable chamber.
Claim 5
Dependent Claim
24 words
The penile implant of claim 3 in which the valve means includes a pressure relief valve which prevents the pressurizable chamber from being over-pressurized.
Claim 6
Dependent Claim
25 words
The penile implant of claim 3 in which the pump means is a pressure bulb and the valve means is located within the pressure bulb.
