Abstract: A pump is connected between penile cylinder(s) and a reservoir of a prosthesis. A squeezing pressure applied to the penile cylinder moves a first liquid volume out of the cylinder and into a first chamber of the pump, which displaces a piston inside of the pump. Displacement of the piston creates a vacuum space (a second chamber) between the piston and the housing of the pump, and a second liquid volume is drawn out of the reservoir and into the vacuum space. A return spring pushes the piston back to its starting position, which pushes both the first liquid volume and the second liquid volume out of the pump and into the penile cylinders.
