Abstract A penile erectile system which is adapted to be surgically implanted in man for the treatment of erectile impotence includes an elongated penile implant adapted to be implanted in the corpus cavernosum of a penis, said member including a stem at one end, a tip at the other end, and first and second internal chambers separated by a dividing wall, said chambers being axially positioned between the stem and tip, the first chamber having a resilient collapsible side wall and the second chamber having a flexible non-distensible side wall. Both of the chambers are normally substantially filled with fluid and are connected by an open passage which extends through the dividing wall which permits fluid to flow between the first and the second chambers. The second non-distensible chamber is pressurized by moving the dividing wall towards the stem and maintaining it in that position thus collapsing the first chamber and forcing pressurizing fluid from the first into the second chamber.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
A penile implant for use in a penile prosthesis comprises an elongated, flexible member of physiologically inert material having at one end a relatively short stem adapted to be inserted into the root end of the corpus cavernosum of a penis; a distal tip adapted to be implanted in the corpus cavernosum of the pendulous penis at the other end; a pair of axially aligned chambers intermediate said stem and said tip, the first of said chambers being collapsible and located adjacent the stem and the second of said chambers being non-distensible and located adjacent the tip, both of said chambers being substantially filled with liquid and separated by a dividing wall having an opening for communication between said chambers and locking means for holding said first chamber in a collapsed condition.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
44 words
A penile implant of claim 1 in which the locking means for holding the first chamber in a collapsed condition consist of a pair of mating members, one on the dividing wall and the second on the interior opposing wall of the collapsible chamber.
Claim 4
Dependent Claim
19 words
A penile implant of claim 2 in which the mating members are a male member and a female socket.
