Abstract

A penile prosthesis for alleviating erectile impotency includes a generally tubular enclosure which is implantable within the corpus cavernosum. The tubular enclosure includes a generally non-distensible pressurizable chamber which when filled with fluid substantially to capacity will transform the prosthesis from the flaccid to an erect state, and a unique inflation valve assembly comprising two valves in longitudinally sequential relationship which will open or close under sequentially applied pressure differential conditions. The prosthesis includes a pump implantable in the body apart from the tubular enclosure, preferably in the scrotum, and a deflation valve.
