A sheath is mounted around the prosthesis' wall and a net sheeting is imbedded under the surface of the prosthesis' wall providing a means to secure the sides; restraining them to further secure a corpora cavernosa around the prosthesis is placed. When the penis is erect it grows in girth thereby causing the sides to diverge, forcing a press-rib against a deep dorsal vein of the penis, which results in restricting blood flow and maintaining erectile rigidity and duration. ## Claims ### Claim 1 A prosthesis adapted for subcutaneous implantation within a human penis having opposing proximal and distal ends, wherein said prosthesis comprises a substantially cylindrical wall wherein portions of said wall are adapted to be movable relative to each other between relative convergent and divergent positions; and at least one sheath secured to the wall. ### Claim 2 (depends on 1) The prosthesis of claim 1 wherein a press-rib located between two of said portions is positioned for pressing against a deep dorsal vein of said penis when said prosthesis is subcutaneously implanted within said human penis. ### Claim 3 (depends on 1) The prosthesis of claim 1 wherein said at least one sheath is at least partially imbedded within said wall. ### Claim 4 (depends on 1) The prosthesis of claim 1 wherein a thickness of said wall diminishes smoothly between said proximal and distal ends and wherein said thickness of said wall is greatest at said proximal end. ### Claim 5 (depends on 1) The prosthesis of claim 1 wherein an outside diameter of said wall diminishes smoothly between said proximal and distal ends and wherein said diameter of said wall is greatest at said proximal end. ### Claim 6 (depends on 1) The prosthesis of claim 1 wherein said wall is longitudinally discontinuous. ### Claim 7 (depends on 1) The prosthesis of claim 1 further comprising a net sheeting imbedded under a surface thereof. ### Claim 8 (depends on 7) The prosthesis of claim 7 wherein said net sheeting is functional as a hinge between said portions of said wall. ### Claim 9 (depends on 1) The prosthesis of claim 1 wherein an interior surface of said wall defines an oblate space there below. ### Claim 10 (depends on 1) The prosthesis of claim 1 wherein the sheath comprises a fabric material. ### Claim 11 (depends on 1) The prosthesis of claim 1 wherein the at least one sheath includes a gauze layer. ### Claim 12 A prosthesis adapted for subcutaneous implantation within a human penis having opposing proximal and distal ends, wherein said prosthesis comprises a substantially cylindrical wall wherein portions of said wall are adapted to be movable relative to each other between relative convergent and divergent positions; and at least one fabric piece positioned at a location at the wall and configured to be sutured to the human penis at a corresponding location. ### Claim 13 (depends on 12) The prosthesis of claim 12 wherein the at least one fabric piece is a gauze fabric. ### Claim 14 (depends on 12) The prosthesis of claim 12 wherein the at least one fabric piece is a sheath. ### Claim 15 A method for improving penis function using a prosthesis, the method comprising: subcutaneous implanting the prosthesis within a human penis, the prosthesis having opposing proximal and distal ends, the prosthesis including a substantially cylindrical wall wherein two portions of said wall are adapted to be movable relative to each other between relative convergent and divergent positions; and causing a third portion of the wall located between said two portions to press against a deep dorsal vein of said human penis, wherein the third portion is a press-rib. ### Claim 16 (depends on 15) The method of claim 15 wherein a thickness of said cylindrical wall diminishes smoothly between said proximal and distal ends and wherein said thickness of said cylindrical wall is greatest at said proximal end. ### Claim 17 (depends on 15) The method of claim 15 wherein the press-rib located is positioned for pressing against the deep dorsal vein of said penis when said prosthesis is subcutaneously implanted within said human penis. ### Claim 18 (depends on 15) The method of claim 15 wherein the prosthesis has a net sheeting imbedded under a surface thereof. ### Claim 19 (depends on 18) The method of claim 18 wherein said net sheeting is functional as a hinge between said portions of said wall.
