Patent ID: 6949114

Claim:
An assembly for introducing a closure material to seal a puncture site in a blood vessel, the closure material comprising a mixture of first and second components which, upon mixing, react to form a solid closure material composition, the assembly comprising a catheter for passage through a tissue puncture track and having a distal end, at least one nozzle located adjacent the distal end, and a catheter lumen in the catheter to convey the first and second components for dispensing through the at least one nozzle, an introducer assembly adapted to communicate with the catheter lumen for dispensing the first and second components into the catheter lumen, the introducer assembly including a mixing chamber including an interior mixing structure to bring the first and second components into a mixed condition before entering the catheter lumen, and a structure carried by the catheter distal to the at least one nozzle and being arranged for expansion within the blood vessel to resist outward passage through the puncture site and to thereby located the at least one nozzle outside the blood vessel adjacent the puncture site.
