Abstract
Abstract A penile erectile system (10) which is adapted to be surgically implanted in man for the treatment of erectile impotence includes a penile implant (11) comprising an elongated, flexible cylindrical member adapted to be implanted in a corpus cavernosum of a penis. The cylindrical member including a pair of concentric chambers (17,18) with both the inner and outer chambers substantially filled with fluid (20) and connected by a passage (21). The inner chamber (17) is non-distensible so that when it is filled and pressurized by transferring fluid (20) thereto from the outer chamber (18) it becomes rigid.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A penile implant having an elongate. cylindrical body (11) with an anchoring stem (12) at the ' proximal end; a tip (14) at the distal end; an inner chamber (17) and an outer chamber (18) located intermediate the length of said body between the stem (12) and the tip (14), the inner chamber (17) being non-distensible so that when pressurized and filled with fluid it becomes rigid and the outer chamber (18) having a volume sufficient to accommodate enough transferable fluid to completely fill and pressurize the inner chamber (17); a passage (21) providing communication between the inner and outer chambers (17,18) and means (25) for retaining fluid (20) transferred from the outer chamber (18) into the inner chamber (17) to keep it pressurized and rigid.
Claim 2
Dependent Claim
126 words
A penile implant having an elongate. cylindrical body (11) with an anchoring stem (12) at the ' proximal end; a tip (14) at the distal end; an inner chamber (17) and an outer chamber (18) located intermediate the length of said body between the stem (12) and the tip (14), the inner chamber (17) being non-distensible so that when pressurized and filled with fluid it becomes rigid and the outer chamber (18) having a volume sufficient to accommodate enough transferable fluid to completely fill and pressurize the inner chamber (17); a passage (21) providing communication between the inner and outer chambers (17,18) and means (25) for retaining fluid (20) transferred from the outer chamber (18) into the inner chamber (17) to keep it pressurized and rigid.
