Abstract
Pumps for use with inflatable implantable penile prostheses in accordance with the invention include features that can provide for free fluid flow during inflation and deflation modes of the pump. Pumps may also include a bypass chamber that is fluidly connected to the fluid passageway by a bypass input channel and a bypass output channel. The bypass chamber comprises a bypass check valve biased toward a closed position.
Claims20
A pump for transferring fluid between a fluid reservoir and at least one inflatable penile prosthesis, the pump comprising:
- a pump housing having a fluid passageway;
- first and second fluid ports in fluid communication with the fluid passageway and operatively connectable to a fluid reservoir and at least one inflatable penile prosthesis, respectively;
- a pump bulb in fluid communication with the fluid passageway that can be operated to transfer fluid between the first and second fluid ports through the fluid passageway;
- a poppet positioned within the fluid passageway, the poppet having an extending portion extending away from a body portion of the poppet, the extending portion having a sealing surface biased toward a valve seat within the fluid passageway;
- a flange extending from a surface of the fluid passageway and toward the interior of the fluid passageway and spaced from the valve seat within the fluid passageway;
- and
- a fluid path between the extending portion of the poppet and the flange when the extending portion of poppet is in contact with the flange wherein the fluid path can allow fluid to pass from one side of the flange to the other.
A pump for transferring fluid between a fluid reservoir and at least one inflatable penile prosthesis, the pump comprising:
- a pump housing having a fluid passageway;
- first and second fluid ports in fluid communication with the fluid passageway and operatively connectable to a fluid reservoir and at least one inflatable penile prosthesis, respectively;
- a pump bulb in fluid communication with the fluid passageway that can be operated to transfer fluid between the first and second fluid ports through the fluid passageway;
- and
- first and second poppets positioned within the fluid passageway and biased toward first and second valve seats within the fluid passageway, respectively, the first poppet having an end slidingly engaged with an end of the second poppet.
A pump for transferring fluid between a fluid reservoir and at least one inflatable penile prosthesis, the pump comprising:
- a pump housing having a fluid passageway;
- first and second fluid ports in fluid communication with the fluid passageway and operatively connectable to a fluid reservoir and at least one inflatable penile prosthesis, respectively;
- a pump bulb in fluid communication with the fluid passageway that can be operated to transfer fluid between the first and second fluid ports through the fluid passageway;
- and
- first and second poppets positioned within the fluid passageway, aligned along a valve axis, and biased toward first and second valve seats within the fluid passageway, respectively;
- and
- a bypass chamber fluidly connected by a bypass input channel to the fluid passageway at a first location and fluidly connected by a bypass output channel to the fluid passageway at a second location, the bypass chamber comprising a bypass check valve biased toward a closed position along a check valve axis and wherein the check valve axis is oriented in a non-parallel manner with respect to the valve axis of the first and second poppets.
