The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A pump adapted to be attached between a fluid reservoir and an inflatable penile cylinder of an inflatable penile prosthesis, the pump comprising:
a pump bulb connected to a pump body, the pump body including a deflate valve chamber communicating with an actuator chamber, the actuator chamber including a restriction ring;
an inlet valve disposed within the pump body;
an exhaust valve disposed within the pump body and in fluid communication with the inlet valve; and
a deflate valve disposed within the pump body between the inlet valve and the exhaust valve, the deflate valve including an end surface movable inside the deflate valve chamber and a base surface movable inside the actuator chamber, the base surface of the deflate valve including a ring engagement surface;
wherein compression of the pump bulb increases fluid pressure in the actuator chamber to displace the base surface of the deflate valve away from the exhaust valve toward the inlet valve to position the deflate valve for inflation of the inflatable penile cylinder; and
wherein the restriction ring of the actuator chamber is sized to engage the ring engagement surface of the deflate valve to maintain the deflate valve in a deflate mode when the base surface of the deflate valve is moved away from the inlet valve toward the exhaust valve to thus allow fluid in the inflatable penile cylinder to bypass the pump bulb and flow from the inflatable penile cylinder to the fluid reservoir.
2. A pump adapted to be attached between a fluid reservoir and an inflatable penile cylinder of an inflatable penile prosthesis, the pump comprising:
a pump bulb connected to a pump body, the pump body including 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 disposed within the pump body between the pump bulb and the deflate valve chamber;
an exhaust valve disposed within the pump body between the pump bulb and the actuator chamber; and
a deflate valve disposed within the pump body between the inlet valve and the exhaust valve, the deflate valve including an end surface movable inside the deflate valve chamber and a base surface movable inside the actuator chamber, the base surface of the deflate valve including a ring engagement surface;
wherein movement of the base surface of the deflate valve away from the inlet valve toward the exhaust valve provides a deflate mode that allows fluid in the inflatable penile cylinder to bypass the pump bulb and flow from the inflatable penile cylinder to the fluid reservoir, and the restriction ring of the actuator chamber is sized to engage the ring engagement surface of the deflate valve to maintain the deflate valve in the deflate mode.
3. The pump of claim 2, wherein the deflate valve is a one-touch release valve adapted to provide user-activated bypass of fluid from the inflatable penile cylinder directly to the fluid reservoir without sustained activation of the deflate valve by the user.
4. The pump of claim 2, wherein the restriction ring of the actuator chamber and the ring engagement surface of the deflate valve combine to provide a fluid seal.
5. The pump of claim 2, further comprising a valve spring located in the pump body between the end surface and the base surface of the deflate valve.
6. The pump of claim 5, wherein the valve spring is adapted to bias the deflate valve to maintain an unactuated state until force is applied to activate the deflate valve.
7. The pump of claim 2, wherein the deflate valve is disposed within the pump body transverse relative to a flow path between the pump bulb and the fluid reservoir.
8. The pump of claim 2, wherein the deflate valve is longer than the deflate valve is wide.
