Claims
- 1. A penile prosthesis comprising at least one elongated, flexible cylindrical implant to be implanted in the pendulous penis, said implant containing a non-distensible inflatable bladder; pump means to be implanted in the scrotum for inflating said bladder with fluid; tubing connecting the pump means to the bladder; valve means for retaining fluid in the bladder; and, a retracting member positioned about said bladder, said retracting member being of an elastic material and smaller than the bladder so that when the bladder is inflated with fluid the retracting member is stretched and will exert pressure upon the bladder so that when the valve is opened and the bladder is permitted to empty, the retracting member will automatically force fluid out of the bladder.
- 2. A penile prosthesis of claim 1 in which the bladder is generally conical shaped and it is longer than the retracting member.
- 3. A penile prosthesis of claim 1 in which the retracting member when stretched by the fully inflated bladder exerts a force of about 70 centimeters of water column to about 100 centimeter of water column upon the bladder.
- 4. A penile prosthesis of claim 1 in which the retracting member is a cylinder of elastomeric material.
- 5. A penile prosthesis of claim 1 in which the retracting member is flexible but does not collapse under its own weight so that it provides the implant with a smooth uninterrupted outer wall.
