SYSTEMS AND METHODS FOR SEALING OPENINGS IN AN ANATOMICAL WALL

摘要

Devices, systems and methods are described herein for sealing openings in an anatomical wall. A sealing system (10) includes an elongate tubular support (12) for delivery to an anatomical opening to be sealed, a cover of bio-compatible material (14) covering a distal portion (20) of the tubular support, and an anchor assembly (16), 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 button, ring or donut, and/or a C-clip. 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.
