Abstract
An inflatable penile prosthesis having at least one inflatable cylinder or pressurizable chamber, a fluid reservoir, pump means, and valves for permitting the flow of fluid between said reservoir and cylinder or chamber as a consequence of pressure changes, wherein to prevent spontaneous inflation there is provided an additional lock-out valve disposed at a point between the reservoir and chamber, which will be opened only by the application of a suitable pressure or force exerted volitionally from without the prosthesis. In a preferred embodiment the prosthesis is of a non-unitary type in which the pump means is in the scrotum.
