Abstract
Methods and apparatus are disclosed for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The methods and apparatus provide for a compaction mechanism that is expandable and tamps the sealing plug into place.
Claims17
A tissue puncture closure device comprising:
- a handle disposed at a first end of the closure device, the handle including a handle housing;
- a filament, a first end extending from the first end at the handle to a second end;
- a carrier tube extending from the handle;
- a sealing plug assembly disposed in the carrier tube and coupled to a second end of the filament;
- and
- an automatic compaction mechanism, wherein a proximal end of the automatic compaction mechanism is coupled to the handle housing and the automatic compaction mechanism extends through the carrier tube, the automatic compaction mechanism comprising at least one linkage, wherein the at least one linkage comprises a plurality of arms and the arms are interconnected by way of pivot points.
