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： A stent graft for deployment in a curved lumen such as the aortic or thoracic arch comprises a constraining mechanism at its proximal end. A stent provided at the proximal end of the stent graft includes loops of material that co-operate with restraining wires that extend between a central guide wire carrier and a restraining wire cannula. The constraining mechanism acts to maintain the proximal stent constrained at both the proximal and distal ends of the proximal stent. The proximal stent is thus allowed to expand after expansion of the remainder of the stent graft during deployment. In an embodiment, the constraining mechanism acts to constrain two adjacent struts of the proximal stent at three points radially therearound, at the proximal end of the stent and at the distal end of the stent. The proximal stent may then overlap with the interior of an adjacent stent at an inner part of a curved vessel.

摘要： Disclosed is a stent graft, including a graft body, a sealing stent at the proximal end of the graft body and completely overlapped by the graft body, and a diameter reducing loop arrangement. The sealing stent includes proximal apices at a proximal end thereof and distal apices at a distal end thereof. The diameter reducing loop arrangement includes a loop element. The loop element includes a first end, a second end, and a strand section from the first end to the second end. The first end is attached to the distal end of the sealing stent. The loop element is configured to pass circumferentially around the distal end of the sealing stent and have a release wire pass through a loop at the second end. The diameter reducing loop arrangement is configured to constrict the distal apices of the sealing stent and cause the sealing stent to adopt a substantially conical or frustoconical shape.

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。

摘要： A stent graft (40) for treating Type-A dissections in the ascending aorta (22) is provided with a plurality of diameter reducing suture loops (56-60) operable to constrain the stent graft during deployment thereof in a patient's aorta. The diameter reducing loops (56-60) allow the stent graft (40) to be partially deployed, in such a manner that its location can be precisely adjusted in the patient's lumen. In this manner, the stent graft can be placed just by the coronary arteries (26, 28) with confidence that these will not be blocked. The stent graft (40) is also provided with proximal and distal bare stents (44,52) for anchoring purposes.
