Abstract
A pump connected to a reservoir and a cylinder of an implantable penile prosthesis includes a pump body and an inlet valve assembly. The pump body has a pump bulb connected to the pump body, where the pump bulb is operable to move fluid between the reservoir and the cylinder. The inlet valve assembly includes a valve and a tubular sleeve that provides an exit valve seat. The inlet valve assembly is disposed in an inlet channel of the pump body and operable to allow a portion of fluid to be drawn from the reservoir through the tubular sleeve and through the inlet channel to the pump bulb for delivery into the cylinder.
Claims14
A pump connected to a reservoir and a cylinder of an implantable penile prosthesis, the pump comprising:
- a pump body and a pump bulb that is connected to the pump body, the pump bulb operable to move fluid between the reservoir and the cylinder;
- and
- an inlet valve assembly comprising a valve and a tubular sleeve that provides an exit valve seat, the inlet valve assembly disposed in an inlet channel of the pump body and operable to allow a portion of fluid to be drawn from the reservoir through the tubular sleeve and through the inlet channel to the pump bulb for delivery into the cylinder;
- wherein the inlet channel of the pump body provides an entry valve seat, and the valve of the inlet valve assembly is movable between the entry valve seat and the exit valve seat.
A penile prosthetic system comprising:
- a cylinder implantable into a penis;
- a reservoir;
- a pump body and a pump bulb that is connected to the pump body, the pump bulb operable to move fluid between the reservoir and the cylinder;
- an inlet valve assembly disposed in an inlet channel of the pump body and operable to allow a portion of the fluid to be drawn from the reservoir through the inlet channel and delivered into the pump bulb;
- and
- an exhaust valve assembly disposed in the pump body and operable to allow the portion of the fluid delivered into the pump bulb to be moved into the cylinder;
- wherein the inlet valve assembly is responsive to a first pressure to allow the fluid to be drawn from the reservoir and delivered into the pump bulb and responsive to a second pressure greater than the first pressure to prevent fluid flowing from the cylinder to the reservoir from passing through the inlet channel;
- wherein the inlet valve assembly comprises a valve that is movable between an entry valve seat and an exit valve seat of the inlet valve assembly, the valve configured to seal against the exit valve seat to prevent fluid flowing from the cylinder to the reservoir from passing the inlet valve.
