    • A vascular closure system includes a suture (204) and an anchor assembly. The anchor assembly includes a first anchor portion (240) having, a plurality of petal members (260) automatically expandable from a retracted position for delivery through a vessel puncture in a vessel, and an expanded position when deployed within the vessel. The anchor assembly also includes a second anchor portion (242) connected to the suture and positioned distal of the first anchor portion within the vessel. Withdrawing the suture pulls the second anchor portion against the first anchor portion to contact the first anchor portion against an inner surface of the vessel (129) adjacent to the vessel puncture. The vascular closure system may also include an automatic compaction assembly that automatically compacts a sealing member (210) against the anchor assembly to seal closed the vessel puncture upon withdrawal of the vascular closure system.
    • 血管闭合系统包括缝合线和锚固组件。 锚固组件包括第一锚定部分,该第一锚固部分具有多个花瓣部件,该多个花瓣部件可自缩回位置自动扩展,以便通过容器中的血管穿刺进行扩张,并且在展开时在容器内展开。 锚固组件还包括连接到缝合线并且定位在容器内的第一锚定部分的远侧的第二锚定部分。 撤回缝合线将第二锚固部分拉向第一锚固部分,以将第一锚固部分抵靠容器的邻近容器穿刺的内表面接触。 血管闭合系统还可以包括自动压实组件,其自动压缩密封构件抵抗锚固组件,以在抽出血管闭合系统时封闭容器穿刺。
