Abstract
A pump assembly for a penile implant is provided having a mechanism that prevents spontaneous inflation of the cylinders implanted within the patient. The preventative mechanism includes a switching mechanism for moving a valve into either a closed or an open position. When closed, the locking valve prevents fluid flow in an adverse direction. While open, the pump functions normally allowing the cylinders to be inflated.
