Abstract
A prosthesis intended for the treatment of a natural lumen or tract of a human or animal body through which a flow is effected on either side of a sphincter is disclosed. The prosthesis comprises at least one tubular element, in particular of cylindrical shape which is sufficiently flexible to conform to the natural lumen, but sufficiently rigid to maintain an artificial passage in the lumen, and is intended to be placed in the natural lumen. The wall of the tubular element comprises a relatively smooth and soft biocompatible material, such as silicone rubber, at least in its outer part.
