摘要：
Devices, systems and methods are described herein for sealing openings in an anatomical wall. A sealing system (10,110,210,310,410,510) includes an elongate tubular support (12,112,212,312,412,512) for delivery to an anatomical opening to be sealed, a cover of material (14,114,214,314,414,514) covering a distal portion of the tubular support, and an anchor assembly (16,116,216,316,416,516), the anchor assembly being designed to secure the cover material to the opening. The anchor assembly can include a plurality of distal anchors (16a) and a plurality of proximal anchors (16b), a donut button, or ring (116,216,316,516) and/or a C-clip (416). In some embodiments, the system further comprises a closure member (32) for closing off an end of the cover material after removal of the tubular support.
