Title:
シースが収縮されたステントグラフト送達システムおよび使用方法
Document Type and Number:
Japanese Patent JP7112393
Kind Code:
B2
Abstract:
A delivery system and method for implanting a stent graft includes a flexible sheath that defines loops distributed longitudinally and wherein substantial alignment of the loops along a longitudinal axis of a guidewire catheter radially constrict the flexible sheath. The flexible sheath defines longitudinal edges that at least partially form a seem when the openings are aligned, whereby, upon alignment, the flexible sheath defines at least one fenestration in the luminal configuration of the flexible sheath. 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 radially constricted configuration.
