Abstract
Prosthesis (8) intended for the treatment of a natural lumen (1) or tract of a human or animal body through which a flow is effected on either side of a sphincter (5), said prosthesis comprising a tubular element (9, 11), in particular of cylindrical shape, which is sufficiently flexible to conform to said natural lumen, but sufficiently rigid to maintain an artificial passage in said lumen, and is intended to be placed in said natural lumen, the wall of said tube comprising a relatively smooth and soft biocompatible material, such as a silicone rubber, at least in its outer part, characterized in that said prosthesis comprises two tubular elements (9, 11), such as are defined in the preamble of the present claim, which are intended to be arranged in said lumen (1) on either side, respectively, of the sphincter (5), and are attached to each other by a flexible and deformable connection means (10) which is intended to be held in the orifice of the sphincter (5), and each said tubular element having an external cross section which is substantially constant from one end to the other of said element.
