Abstract
Abstract A penile prosthesis which is adapted to be surgically implanted in man for the treatment of erectile impotence includes at least one elongated, flexible cylindrical member which is adapted to be implanted into the corpus cavernosum of the pendulous penis, a pressure bulb for pressurizing liquid and tubing connecting the member and the bulb. The member includes an inner non-distensible pressure chamber and an outer distensible chamber. The two chambers are connected by a passage and a valve for controlling flow through the passage so that fluid can be transferred from the pressure bulb via the pressure chamber to the outer chamber to cause it to distend and in turn increase penile girth.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
124 words
In a penile prosthesis having a non-distensible pressure chamber for implantation in the pendulous penis, a pressure bulb for implantation in the scrotum, a length of tubing connecting the pressure bulb to the pressure chamber and a valve for controlling the flow of pressurizing fluid from the bulb to the chamber, the improvement which comprises a distensible chamber concentric with and outside of the pressure chamber, a passageway connecting the pressure chamber to the distensible chamber and manually operable valve means for controlling fluid flow between the pressure chamber and the distensible chamber so that when the valve means is opened and the pressure bulb is squeezed fluid can flow into and expand the distensible chamber thereby increasing the girth of the pendulous penis.
Claim 2
Dependent Claim
124 words
In a penile prosthesis having a non-distensible pressure chamber for implantation in the pendulous penis, a pressure bulb for implantation in the scrotum, a length of tubing connecting the pressure bulb to the pressure chamber and a valve for controlling the flow of pressurizing fluid from the bulb to the chamber, the improvement which comprises a distensible chamber concentric with and outside of the pressure chamber, a passageway connecting the pressure chamber to the distensible chamber and manually operable valve means for controlling fluid flow between the pressure chamber and the distensible chamber so that when the valve means is opened and the pressure bulb is squeezed fluid can flow into and expand the distensible chamber thereby increasing the girth of the pendulous penis.
Claim 3
Dependent Claim
43 words
A penile prosthesis of claim 1 in which there are two separate implants each with a pressure chamber for implanting into the corpora cavernosum of a pendulous penis, a single pressure bulb and tubing connecting the single pressure bulb to the pressure chambers.
