Abstract: A stent is a device that is adapted to be implanted into narrowed portions of hollow vessels of a body. The stent (1) comprises a stent body (2) that has at least two different wall thicknesses (WE, WH). The different wall thicknesses result in different flexibility characteristics of the stent in the longitudinal direction. Thus the stent according to the invention prevents irritations of the wall of the vessel in the area of the implanted stent, whereby the risk of restenosis in said area can be reduced considerably.

Abstract: A stent (1) has a tubular flexible body (2) with the wall (3) having a web structure (4). The web structure (4) of the wall (3) has cells formed by a pair of adjacent sinuous web patterns (5,6) that are interconnected by linking elements (22) to form elastic elements.

Abstract: A coronary stent having a tubular, flexible body is disclosed. The body has a wall which has a web structure. The web structure has a plurality of neighboring cells which are defined by webs and which are each connected via joint webs to neighboring cells. The stent has in axial direction first and second cells that differ form one another and are alternately arranged in axial direction of the stent. The identical cells are provided in neighboring fashion in circumferential direction. In a non-expanded state of the stent, the first cells have folded webs at two opposite sides, and in the non-expanded state the second cells are provided at all sides with web portions that are folded and/or placed together.

Abstract: A device for implanting into a body vessel in the region of a vessel branching has a radially expandable stent formed as a hollow cylindrical element and provided with an increased radial opening, and a balloon catheter on which the stent is pre-mounted for implanting in the vessel, the balloon catheter having a hollow chamber for passage of a guiding wire so that it exits in a center of the increased opening from the hollow chamber and the stent.

Abstract: A coronary stent having a tubular body is disclosed. The tubular body has a wall which has a web structure and a flexible tip at at least one of its front ends. The web structure has a plurality of neighboring cells that are defined by webs.

Abstract: A stent graft has two coaxially arranged, radially expandable stents, and a flexible, stretchable material layer arranged between the stents. Both stents are directly connected with one another in their end regions and the material layer is formed as a fabric band wound around an inner stent.
