Orthotopic artificial bladder prosthesis

摘要

An orthotopic prosthesis (1) of artificial bladder includes a balloon (600), two hollow elements (300) for the forced fitting of ureters (6,6′) and a frustoconical element (602) for the connection of the urethra (8) to the prosthesis in the absence of stitches.

主权项

1. An orthotopic artificial bladder prosthesis (1) comprising a collapsible balloon (600) made of a silicone multi-layer membrane (2) having an outer surface (601) and an inner surface (604) both coated with a coating selected from the group consisting of pyrolytic turbostratic carbon and diamond-like carbon, provided with two tubular elements (10) extending outwards adapted for connecting ureters (6, 6′) to said prosthesis (1) by means of a forced fit, and with a conical frustum (602) suitable for connecting an urethra (8) to said prosthesis,
wherein said conical frustum (602) is made of a mesh-reinforced silicone (5) and said tubular elements (10) contain internally a plurality of projections (16) adapted to detain said ureters (6,6′) after being fitted forcedly, and wherein each tubular element (10) is a tubular portion of a hollow conic element (300) coated internally and externally with a coating selected from the group consisting of pyrolytic turbostratic carbon and diamond-like carbon, and it is connected to a frustoconical portion (14) having a widened base (13) adapted to be glued to the inner surface of the balloon (600) so as to render said hollow conic element (300) integral with said balloon (600).
