Abstract
A method and apparatus 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 method and apparatus provide for disengagable automatic tamping and/or cinching of the sealing plug when the apparatus is withdrawn from the puncture site. The disengagable automatic tamping and/or cinching is facilitated by transducing a motive force generated by the withdrawal of the apparatus into a tamping and/or cinching force.
