(EN) A delivery system and method for implanting a stent graft includes a flexible sheath that defines openings distributed longitudinally and wherein substantial alignment of the openings along a longitudinal axis of a guidewire catheter radially constrict the flexible sheath. The flexible sheath includes at least one fenestration. A ligature extends through the openings of the flexible sheath and causes the openings to be substantially aligned, thereby constraining the flexible sheath. The ligature is proximally retractable from the openings to thereby release the flexible sheath from a radiallyconstricted configuration.
(ZH) 用于植入支架移植物的递送系统和方法,包括限定纵向分布的开口的柔性护套,并且其中开口沿导丝导管的纵向轴线的大致对齐使柔性护套径向收缩。柔性护套包括至少一个开窗。结扎线穿过柔性护套的开口延伸并使开口大致对齐,从而约束柔性护套。结扎线可从开口向近侧缩回,从而使柔性护套从径向收缩构造释放。
