Abstract
A penile prosthesis consists of a pair of inflatable penile implants which each having a cylindrical body which contains a hydraulic system including a pressure chamber, a reservoir for pressurizing fluid, and a pump for transferring fluid under pressure to the pressure chamber to make it rigid. Each implant also contains a longitudinally compressible, but radially incompressible bellows in the reservoir which expands when the reservoir is empty and prevents the reservoir wall from collapsing. In one embodiment, a tube extends from the pump in the tip to the reservoir at the rear through the pressure chamber and there is a restricted orifice through which fluid can bleed back into the reservoir from the pressure chamber thus automatically controlling the length of time that the pressure chamber is pressurized and rigid.
