Abstract: The present invention provides a stent comprising a tubular flexible body having a wall with a web structure that is expandable from a contracted delivery configuration to deployed configuration. The web structure comprises a plurality of neighboring, interconnected, web patterns, each web pattern composed of adjoining webs. Each adjoining web comprises a central section interposed between two lateral sections, forming concave or convex configurations. Embodiments of the present invention comprising curvature for tracking tortuous anatomy and reducing localized restoring forces are provided. Methods of using stents in accordance with the present invention are also provided.

Abstract: Apparatus and methods for stenting are provided comprising a stent attached to a porous biocompatible material that is permeable to endothelial cell ingrowth, but impermeable to release of emboli of predetermined size. Preferred stent designs are provided, as well as preferred manufacturing techniques. Apparatus and methods are also provided for use at a vessel branching. Moreover, embodiments of the present invention may comprise a coating configured for localized delivery of therapeutic agents. Embodiments of the present invention are expected to provide enhanced embolic protection, improved force distribution, and improved recrossability, while reducing a risk of restenosis and thrombus formation.

Abstract: Apparatus and methods for providing distal protection during a medical procedure comprising a vascular filter having a self-expanding, porous foam body that conformably seals against a vessel wall and captures emboli within one or more recesses. The filter is coupled to a distal region of an elongated member, such as a guide wire. Delivery systems for use with filters of the present invention and methods of using the apparatus of the present invention also are provided.

Abstract: A device for treatment of mitral annulus dilation is disclosed, wherein the device comprises two states. In a first of these states the device is insertable into the coronary sinus and has a shape of the coronary sinus. When positioned in the coronary sinus, the device is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

Abstract: The present invention relates to a stent (1) comprising a tubular flexible body (2) whose wall (3) has a web structure (4) which can pass from a non-expanded state into an expanded state. The web structure (4) comprises a plurality of neighboring web patterns (5, 6) which, in turn, consist of adjoining webs (9, 10 and 9′, 10′, respectively). The web patterns (5, 6) are interconnected. Each web (9, 10 and 9′, 10′ respectively) comprises three portions (9a, 9b, 9c and 10a, 10b, 10c, respectively) that are arranged at an angle (&agr;, &bgr;) relative to one another.
