摘要：
Devices, systems and methods are described herein for sealing openings in an anatomical wall. A sealing system includes an elongate tubular support for delivery to an anatomical opening to be sealed, a cover of bio-compatible material covering a distal portion of the tubular support, and an anchor assembly, the anchor assembly being designed to secure the cover material to the opening. The anchor assembly can include a plurality of distal anchors and a plurality of proximal anchors, a button, ring or donut, and/or a C-clip. In some embodiments, the system further comprises a closure member for closing off an end of the cover material after removal of the tubular support.
