ABSTRACT:
A penile prosthesis implantable within the corpus cavernosum of the penis in order to alleviate erectile impotency includes a unique deflation valve mechanism for returning the prosthesis from the erect to the flaccid state. In its preferred embodiment the prosthesis is of a unitary type comprising a distal portion including a pump, a medial portion defining a pressurizable chamber comprising an internal, tubular, substantially non-distensible portion and a concentric tubular sleeve, and a proximal portion including a fluid reservoir, the latter being in fluid communication with the pump. The deflation valve mechanism is activated in accordance with pressure differential conditions within the valve and a movable or distensible partition capable of exerting an internal force within the valve to place the valve in an open mode, thereby effecting the deflation of the prosthesis or hydraulic system in which the valve mechanism is present. Apparatus for extending the length of the prosthesis are also provided.
