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 web patterns, where each web patterns is composed of adjoining webs, and the web patterns are interconnected. Each adjoining web comprises a central section interposed between two lateral sections to form concave or convex configurations.

Methods and apparatus for a stent having an expandable web structure

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

Compact stent

Apparatus and methods for stenting are provided comprising a self-expandable stent that is at least partially covered with a biocompatible material configured to prevent dynamic self-expansion of the stent. The biocompatible material is irreversibly expandable by suitable means, for example, a balloon. Thus, the apparatus may be tailored in-vivo to a vessel profile, in a manner similar to a balloon-expandable stent, but maintains the flexibility required for use in tortuous anatomy and in vessels that undergo temporary deformation, in a manner similar to a self-expandable stent. Apparatus is also provided for stenting at a vessel branching, and for localized delivery of therapeutic agents.

Methods and apparatus for in-vivo tailored stents indicated for use in tortuous anatomy

A stent (,) has a tubular flexible body (,) with the wall (,) having a web structure (,). The web structure (,) of the wall (,) has cells formed by a pair of adjacent sinuous web patterns (,) that are interconnected by linking elements (,) to form elastic elements.

Stent

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.

Coronary stent

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.

Balloon catheter and multi-guidewire stent for implanting in the region

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.

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.
