Abstract: A stent device and methods for inserting and removing a stent to and from an anatomical tract of a living being. The stent includes a distal segment and a proximal segment joined by a flexible connection structure. The stent is inserted using components comprising a delivery assembly such that the stent proceeds through the anatomical tract and seats the flexible connection structure of the stent in a natural constricting structure of the anatomical tract. The flexible quality of the connection structure permits the natural constricting functions of the anatomical tract to occur. The natural closure of the anatomical constricting structure stops the flow of fluid, for example, from a target organ which indicates that the stent is properly placed within the anatomical tract.

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.

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
