摘要： A method for treating a bifurcated vessel, wherein the bifurcated vessel has a main vessel and a side branch vessel extending from the main vessel. The method includes the steps of: identifying a site in the main vessel and placing a stent at the site in the main vessel. The stent includes a lattice defining a substantially cylindrical configuration having a proximal end portion and a distal end portion, and a middle portion between the proximal end portion and the distal end portion. The lattice is movable from a crimped state to an expanded state. The lattice has a plurality of adjacent hoops. Each hoop has a plurality of adjacent loops, a plurality of bridges connecting adjacent hoops, and a plurality of extensions on at least some portions of the lattice. Each of the hoops and bridges define a cell. The proximal end portion and the distal end portion of the lattice have at least one cell respectively and the middle portion of the lattice has at least one cell. The at least one cell of the middle portion has spacing between adjacent hoops that is greater than spacing between adjacent hoops of the at least one cell of the proximal end portion and the distal end portion respectively. The at least one cell of the middle portion is dilated adjacent the side branch vessel and a surface of the side branch vessel is supported with at least one of the plurality of the extensions by deformably moving the at least one of the plurality of extensions away from the lattice and into contact with the surface of the side branch vessel.

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.
