摘要： A device and method for treating a body conduit/lumen having an undesired reduced diameter include delivering an expandable stent in a contracted configuration to a target location. The stent has small cells that form an open tight mesh providing the effective capture of small particles such as thrombi. Preferably, the tight mesh is combined with structure that permits creation of large side openings to accommodate lumen branches.

摘要： A stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an “N”), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents.

摘要： The present invention relates to a medical device, and in particular, to a stent-based valve. The valve includes a radially expandable structural frame comprising a proximal anchor and a distal anchor. The proximal and distal anchors are formed from a lattice of interconnected elements, and have a substantially cylindrical configuration with first and second open ends and a longitudinal axis extending there between. The stent based valve also comprises one or more connecting members, each having a first and a second end. The first end of each connecting member is attached to the proximal anchor and the second end of each connecting member is attached to the distal anchor. A biocompatible valve assembly is attached to the proximal anchor and extends distally along the one or more connecting members.
