Abstract: This invention relates to a medical device comprising an implant for the treatment of an affection of an anatomical duct. A part of the duct (V) wall is lined on the outside with at least one lining (140′a), essentially facing the proximal and/or distal ends of the implant (100). Means of fastening (361) the lining to the implant apply, through the duct wall, the implant against this duct, and means of setting both the lining and the fastening means allow their positioning around said duct. In particular, application to the treatment of an aneurysm.

Abstract: The system-for repairing an anatomic duct comprises an implant having a tubular body adapted to be radially expanded, once the implant is arranged in the duct and also a device for installing the implant in said duct. The device comprises a tie for maintaining the body in a restricted configuration, for the implantation thereof in the duct, and means for releasing the tie in order to allow the implant to radially expand.

The filter may have legs in the shape of a corolla and extensions for retaining it in place in the blood vessel, which naturally define a cylinder. Its use is for the treatment of risk of embolism.

Abstract: A prosthesis which can be implanted in a human or animal duct to ensure a passageway in the duct. The prosthesis is formed from several filaments which have corrugations and which are wound to define a tubular surface. The corrugations form an advantageously zig-zagged series of rings that are stepped along the length of the prosthesis, with corrugated portions of the individual filaments constituting portions of two or more separate ones of the rings.
