Abstract

See full text

A stent graft includes a tubular graft element to which there are attached a plurality of stent rings. The stent rings are formed of a plurality of stent struts arranged in a zig-zag arrangement with alternating peaks and valleys. The end-most stent is located at the proximal end of the graft tube. Between adjacent peaks of the end most stent, there is provided a series of bridging elements. These are preferably formed of Nitinol wire and to be substantially more flexible than the stent struts. The bridging elements extend in the region of graft material between adjacent stent peaks and are attached to the graft material, for example by suturing. The bridging elements are substantially more flexible than the stent ring and therefore impart little opening force on the graft material in comparison to the force produced by the stent ring. However, the bridging elements impart enough force on the flaps of graft material between the peaks of the stent ring keep these flaps open, that is against the vessel wall. The bridging elements can provide integral barbs.
