1. 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.
