摘要： 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.
摘要翻译： 支架移植物包括管状移植元件，其上附接有多个支架环。 支架环由多个支架支柱形成，该支架支架布置成具有交替的峰和谷的之字形排列。 最终的支架位于移植管的近端。 在最终支架的相邻峰之间，提供了一系列桥接元件。 这些优选由镍钛诺丝形成，并且比支架支柱基本上更灵活。 桥接元件在相邻支架峰之间的移植材料区域中延伸并且例如通过缝合附着到移植物材料上。 桥接元件比支架环基本上更加柔性，因此与支架环产生的力相比，在接枝材料上施加很小的打开力。 然而，桥接元件在支架环的峰之间的移植材料的翼片上赋予足够的力使得这些瓣片打开，即抵靠血管壁。 桥接元件可以提供整体倒钩。
