摘要： The disclosure provides a filter apparatus and method of filtering in a body vessel. The filter apparatus comprises a filter unit and an expandable introducer designed to deliver the filter unit to the target filtering site. The filter unit attaches to the expandable introducer via a plurality of anchors on the filter unit. The expandable introducer delivers and presses the anchors to the vessel wall during implantation. After implantation, the filter unit exerts minimal or about zero radial force against the vessel wall.

摘要： A pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. Indwelling access sheaths are provided within auxiliary lumens of a pusher catheter and dilators are preloaded into the access sheaths along with the indwelling guide wire. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate cathertization of a side branch or target vessel through the fenestration or be used to stabilize the access sheath during catheterization, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

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。
