Claim Text:
1. An apparatus for sealing a puncture extending through tissue, comprising: a tubular member comprising a proximal end, a distal end sized for insertion through the puncture, a lumen extending between the proximal and distal ends, and a distal opening in communication with the lumen; a plug disposed within the lumen, the plug comprising a first precursor disposed on at least a portion of an exterior of a core of the plug, the first precursor remaining in an unreactive state prior to exposure to an aqueous physiological environment in the tissue whereupon the first precursor reacts to form a sticky hydrogel to retain the plug in place within the puncture; and a pusher member slidable within the lumen of the tubular member for deploying the plug through the lumen and out the distal opening of the tubular member, wherein the plug and/or hydrogel are swellable in the physiological environment.
