Abstract
A pump adapted to be attached between a fluid reservoir and an inflatable penile cylinder of an inflatable penile prosthesis includes a pump bulb connected to a pump body. The pump body includes a deflate valve chamber communicating with an actuator chamber, a deflate cap attached to the deflate valve chamber, and the actuator chamber including a restriction ring. An inlet valve is disposed within the pump body between the pump bulb and the deflate valve chamber. An exhaust valve is disposed within the pump body between the pump bulb and the actuator chamber. A deflate valve is disposed within the pump body between the inlet valve and the exhaust valve. The restriction ring in the actuator chamber is sized to engage a ring engagement surface of the deflate valve to maintain the deflate valve in the deflate mode.
