Abstract
A closure device (200) includes a filament (204), an anchor (208), a sealing pad (210), and an automatic driving mechanism. The anchor is configured to be inserted through the tissue wall puncture and is attached to the filament at the second end of the closure device. The sealing pad is slidingly attached to the filament at the second end of the closure device. The automatic driving mechanism includes a compaction member (212), at least one slide member (230, 232) at the first end of the closure device, and a biasing member (234). The biasing member is carried by the at least one slide member and operable to distally advance the compaction member for automatically compacting the sealing pad toward the anchor upon withdrawal of the closure device from the internal tissue wall puncture.
