Abstract:
An apparatus having a distal end, the apparatus sized and configured for introducing a catheter instrument through a vessel puncture site and introducing a closure composition to seal the vessel puncture site after removal of the catheter instrument, the apparatus comprisinga unitary elongated body adapted for passage through a tissue puncture and having an end region defining the distal end of the apparatus and adapted to occupy a position adjacent the vessel puncture site, the body including a circumferential wall having an inner surface and an outer surface, a first lumen in the elongated body, the first lumen being defined by the inner surface of the circumferential wall and accommodating passage of a catheter instrument through the vessel puncture site and removal of the catheter instrument from the vessel puncture site, a closure composition comprising a combination of closure components which, when combined, react to form the closure composition, a second lumen in the elongated body separate from the first lumen and being defined by a bore within the circumferential wall between the inner and outer surfaces, the second lumen having a fluid delivery port located at a fixed distance from the distal end of the apparatus, the second lumen being adapted for introducing the closure composition to seal the vessel puncture site after removal of the catheter instrument, and one or more dispensers in fluid communication with the second lumen for dispensing the closure components as a combination that reacts in situ to form the closure composition adjacent the vessel puncture site, the first and second lumens being at least partially free of communication with each other.
