Abstract
An improved penile prosthesis includes at least one elongated, flexible cylinder containing a non-distensible bladder for implantation in the pendulous penis; a pump for implantation in the scrotal sac; tubing connecting the pump to the bladder; a valve for retaining the fluid in the bladder; and, an elastic retracting cylinder positioned about the bladder. The retracting cylinder is smaller than the fully inflated bladder and stretches when the bladder is inflated. When the bladder is fully inflated and valve is opened to permit fluid to exit, the stretched retracting cylinder automatically forces fluid out of the bladder.
