Abstract

Abstract A penile erectile system which is adapted to be surgically implanted in man for the treatment of erectile impotence includes at least one penile implant comprising an elongate, flexible cylindrical body (11) adapted to be implanted in the corpus cavernosum of a penis, said body (17) having a tip (14) at one end and an anchoring stem (12) at the other end and an intermediate section including a pair of inner and outer chambers (17, 18) substantially filled with fluid and connected by a passage (21, 22, 26, 27). The body (11) also includes internal pump means (19) for transferring fluid into the inner chamber (17) and a control valve (29) for controlling pressure in the inner chamber (17). The inner chamber (17) is non-distensible so that when it is filled and pressurized by transferring fluid thereto it becomes rigid and supports the penis in an erect state.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 105 words
A penile implant having an elongate unitary body (11) with a tip (14) at one end and an anchoring stem (12) at the other end and including an intermediate inner chamber (17) with a radially disposed outer chamber (18), the inner chamber (17) being non-distensible so that when pressurized and filled with fluid it becomes rigid; a passage (21, 22, 26 27) providing communication between said inner and outer chamber (17, 18); pump means (19) within the body for transferring fluid to the inner chamber to pressurize it and make it rigid and a control valve (29) for controlling the pressure in said inner chamber.
Claim 2
Dependent Claim 105 words
A penile implant having an elongate unitary body (11) with a tip (14) at one end and an anchoring stem (12) at the other end and including an intermediate inner chamber (17) with a radially disposed outer chamber (18), the inner chamber (17) being non-distensible so that when pressurized and filled with fluid it becomes rigid; a passage (21, 22, 26 27) providing communication between said inner and outer chamber (17, 18); pump means (19) within the body for transferring fluid to the inner chamber to pressurize it and make it rigid and a control valve (29) for controlling the pressure in said inner chamber.
Claim 3
Dependent Claim 41 words
The implant as claimed in claim 1, in which both chambers (17, 18) are normally substantially filled with hydraulic fluid and the outer chamber (18) contains enough fluid which can be transferred to fill and pressurize the inner non-distensible chamber (17).
Claim 4
Dependent Claim 27 words
The implant as claimed in claim 1 or claim 2, in which the control valve means (29) is located near the stem (12) of the body (11).
Claim 5
Dependent Claim 21 words
The implant as claimed in claim 1 or claim 2, wherein the tip (14) is tapered and made of self-sealing material.
Claim 6
Dependent Claim 22 words
The implant as claimed in any one of the preceding claims, in which the pump (19) is located adjacent the tip (14).
Claim 7
Dependent Claim 18 words
A penis erectile system including one or more of the implants of any one of the preceding claims.
