An inflatable penile implant includes a novel compensator which both absorbs any increased pressure to protect the components of the hydraulic system from pressure damage and which permits the implant to be shortened in length without impairing its function. An improved tapered pumping chamber, improved pump valve and an improved pressure relief valve are also disclosed.

An improved penile prosthesis to be surgically implanted in man for the treatment of erectile impotence includes at least one elongated, flexible cylinder containing therein a hydraulic system comprising a pressure chamber, a reservoir and a pump. It also includes an outer girth adjusting chamber concentric with the pressure chamber. The girth adjusting chamber is connected by tubing to a pressure bulb located outside the cylinder so that the girth adjusting chamber can be inflated and the girth of a penis increased by transferring fluid from the pressure bulb to the adjusting chamber.
