Patent ID: 8241203

Claim:
An inflatable penile prosthesis (IPP) comprising: a fluid reservoir; at least one inflatable penile cylinder; a fluid transfer system in fluid communication with the fluid reservoir and with the at least one inflatable penile cylinder to inflate the at least one penile cylinder with fluid from the fluid reservoir, the fluid transfer system comprising an inlet valve in fluid communication with the fluid reservoir, a fluid transfer bulb in fluid communication with the inlet valve, an exhaust valve in fluid communication with the fluid transfer bulb, and a spool valve assembly in fluid communication with the fluid transfer bulb and at least one inflatable penile cylinder; and a cylinder deflate mechanism in fluid communication with the fluid reservoir and with the at least one inflatable penile cylinder to return fluid from the at least one inflatable penile cylinder to the fluid reservoir, the cylinder deflate mechanism comprising the spool valve assembly, a return valve in fluid communication with the reservoir and the at least one inflatable penile cylinder, and a deflate actuator arranged to shift the spool valve assembly to a cylinder deflate mode, wherein the spool valve assembly can be shifted between a cylinder inflate mode and the cylinder deflate mode using a force external to the spool valve assembly.
