Abstract
The present invention relates to an endoprosthesis for delivery in a body lumen that includes a plurality of web rings coupled one to the other by flexible connectors, which are structured to absorb at least some of the axial and torsional stresses applied to the endoprosthesis and to improve resistance of the endoprosthesis to clinical fatigue. The connectors are each composed of struts sequentially adjoined one to the other, with foot-shaped extensions protruding at the intersections of pairs of the struts.
