Abstract
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.
