Abstract

The present invention provides a stent comprising a tubular flexible body (2) having a wall with a web structure (4) that is expandable from a contracted delivery configuration to deployed configuration. The web structure comprises a plurality of neighboring, interconnected, web patterns (5, 6), each web pattern composed of adjoining webs (9, 10). Each adjoining web comprises a central section (9b, 10b) interposed between two lateral sections (9a, 10a, 9c, 10c), forming concave or convex configurations. Embodiments of the present invention comprising displaying curvature, to track tortuous anatomy and reduce localized restoring forces, are provided.
