Abstract:
1. A system for sealing a puncture extending through tissue, comprising: a cartridge comprising a tubular member sized for insertion into a puncture; a carrier carried within the tubular member and having a predetermined shape and sized for delivery into the puncture, the carrier formed from material configured to expand upon exposure to an aqueous physiological environment to occlude the puncture and carrying at least one adherent layer component; a delivery device comprising at least one additional adherent component therein and configured for delivering the at least one additional adherent layer component to the carrier in situ; and wherein contact between the at least one adherent layer component and the at least one additional adherent layer component in situ causes them to react with one another to create an adherent layer on the carrier, wherein the carrier has a lumen extending between ends of the carrier, the system further comprising a positioning member extending through the carrier lumen and the cartridge, the positioning member comprising an expandable positioning element on a distal end thereof beyond the cartridge, the positioning element expandable from a contracted condition for advancement through the puncture into the blood vessel and an expanded condition for preventing the carrier from being deployed within the blood vessel.
