Abstract
Abstract An inflatable penile implant includes a novel pressure accumulating chamber which has a wall which stretches to expand the volume of the chamber when the normal working pressure of the implant has been exceeded. The expansion in the volume of the chamber absorbs and compensates for any increased pressure and thereby protects the components of the hydraulic system from pressure damage.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
96 words
In an inflatable penile implant comprising a generally cylindrical body containing a hydraulic system which includes a non-distensible pressure chamber, a reservoir and a pump for transferring pressurizing fluid from the reservoir to the pressure chamber, the improvement which comprises said non-distensible pressure chamber having a minor portion thereof a wall which expands outwardly of said pressure chamber to increase the volume of the pressure chamber when the normal working pressure of the hydraulic system of the implant has been exceeded thereby absorbing and compensting for any increased pressures which might otherwise damage the hydraulic system.
Claim 2
Dependent Claim
