Abstract
An implantable penile prosthesis having an inflatable cylinder with at least one piezoelectric pump for transferring fluid between an integrated reservoir and pressure chamber within the inflatable cylinder. The piezoelectric pump includes an actuator powered by an inductor coil integrated into the inflatable cylinder allowing for wireless control of the inflation and deflation of the inflatable cylinder. An external control system having a corresponding inductive coil can be used to supply a magnetic field for creating a current in the inductor coil integrated into the inflatable cylinder.
Claims12
An implantable penile prosthesis system, comprising:
- at least one elongated body implantable within a corpus cavenosum of a patent, the at least one elongated body including:
- an expandable cylinder enclosing a fluid reservoir;
- a piezoelectric pump including an actuator;
- a pressure cylinder;
- and
- a rod configured as a guide for the actuator, the rod defining a channel providing a fluid communication between the fluid reservoir and the pressure cylinder, the actuator configured to move along the rod;
- and
- a wireless external control system;
- wherein the piezoelectric pump selectively transfers fluid from the fluid reservoir to the pressure cylinder by movement of the actuator along the rod in response to a signal from the wireless control system so that the expandable cylinder selectively transitions between a flaccid disposition and an erect disposition.
