Abstract
A pump for an implantable penile prosthesis has a pump body attachable between a penile implant and a reservoir containing a liquid. A deflate valve assembly is placed within the pump body and has a sleeve sealed inside of the pump body and a stem that is movable longitudinally within the sleeve. A groove is formed in an exterior surface of the stem. The stem is longitudinally movable within the sleeve to align the groove with both an inlet flow path and an exhaust flow path to form a deflation flow path between the penile implant and the reservoir.
Claims17
A pump adapted to inflate an implantable penile prosthesis, the pump comprising:
- a pump body adapted to be coupled between a penile implant and a reservoir containing a liquid;
- an inlet flow path formed in the pump body that is configured to allow the liquid to enter the pump body from the reservoir;
- an exhaust flow path formed in the pump body that is configured to allow the liquid to exit the pump body and flow to the penile implant;
- and
- a deflate valve assembly comprising a sleeve sealed inside of the pump body and a stem that is movable longitudinally within the sleeve, with a groove formed in an exterior surface of the stem;
- wherein the stem is longitudinally movable within the sleeve to align the groove with both the inlet flow path and the exhaust flow path to form a deflation flow path between the penile implant and the reservoir;
- wherein the groove includes a longitudinal segment aligned with a longitudinal axis of the stem and a lateral segment connected to and extending from the longitudinal segment.
