    • PROBLEM TO BE SOLVED: To retreat a sheath member more smoothly and more easily while deploying a stent graft in relation to a method and system for deploying an intravascular prosthesis in a vascular system and the associated stent graft. SOLUTION: A proximal anchor stent ring of the intravascular prosthesis includes a proximal apex, a distal apex, a strut extending between these proximal and distal apexes, and anchoring pins. The strut, the proximal apex and the distal apex define an imaginary cylindrical surface. A pair of the anchoring pins is adjacently disposed in the strut for each proximal apex. The anchoring pins extend inward from the inner surface of the strut and protrude outward radially from the cylindrical surface with the strut as the starting point. By locating the anchoring pins inward, the delivery profile of the proximal anchor stent ring can be minimized. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:相对于在血管系统和相关联的支架移植物中展开血管内假体的方法和系统来展开支架移植物,更平稳地和更容易地撤退护套构件。 解决方案:血管内假体的近端锚固支架环包括近端顶点,远端顶点,在这些近端和远端顶点之间延伸的支柱和锚定销。 支柱,近端顶点和远端顶点限定了假想的圆柱形表面。 一对锚定销相邻地设置在每个近端顶点的支柱中。 锚定销从支柱的内表面向内延伸,并以支柱为起点从圆柱形表面径向向外突出。 通过向内定位固定销,近端锚固支架环的输送轮廓可以最小化。 版权所有(C)2008,JPO&INPIT
