Abstract
Abstract The prosthesis, to be applied surgically inside one of the cavernous bodies, consists, according to a preferred embodiment, of a series of spheres slightly flattened at the poles and provided with a double row of holes. The spheres are interconnected by a thread which, if tensed by proper devices, causes the stiffening of the prosthesis.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
A semi-rigid penial prosthesis comprising independent elements having complementary contact surfaces, said elements being slightly flattened at their contact ends and having two holes through which passes a thread, one of said elements having a groove therein, a second of said independent element having a concave opening, and a base element with an upper and lower part, the upper part of said base element longer than the lower part, said base element having a convex end and, internally, a cuneiform opening, and a head element, all of said elements connected by a thread passing through said holes and through said opening in the base element, and said thread passing through said head element, a helical spring separating the head element from a closure element, all of said elements enclosed in a sheet made of silicone elastomer.
Claim 2
Dependent Claim
136 words
A semi-rigid penial prosthesis comprising independent elements having complementary contact surfaces, said elements being slightly flattened at their contact ends and having two holes through which passes a thread, one of said elements having a groove therein, a second of said independent element having a concave opening, and a base element with an upper and lower part, the upper part of said base element longer than the lower part, said base element having a convex end and, internally, a cuneiform opening, and a head element, all of said elements connected by a thread passing through said holes and through said opening in the base element, and said thread passing through said head element, a helical spring separating the head element from a closure element, all of said elements enclosed in a sheet made of silicone elastomer.
Claim 3
Dependent Claim
18 words
A semi-rigid penial prosthesis as defined in claim 1, wherein said sheath is made of a silicone sponge.
Claim 4
Dependent Claim
69 words
Semi-rigid penial prosthesis according to claim 1, comprising a number of elements that may be variously coupled, so that the overall length differs, connected together by a substantially unextensible element, on the inside thereof, said element secured to an elastic means at its end, suitable for exerting on said unextensible connecting element a pulling which tends to keep close together said variously couplable means of which the prosthesis consists.
Claim 5
Dependent Claim
95 words
A prosthesis according to claim 1, and providing for a support to be applied at the root of the cavernous bodies; a series of spheres connected with said support by means to an unextensible filiform element, that can move in contrast to elastic means; a central body located between said spheres and said support, said central body being so shaped as to allow the spheres to be shifted from a position in which said thread is kept tensed by said elastic means to a position in which no pulling is exerted on said thread anymore.
