Abstract
Systems and methods introduce a closure material to seal a vessel puncture site. The system and methods provide a catheter adapted for passage through a tissue puncture and sized to occupy substantially all the tissue puncture. The catheter includes a lumen in fluid communication with a fluid delivery port adjacent the catheter distal end. One or more dispensers are in fluid communication with the catheter lumen for dispensing first and second fluid compositions in the catheter lumen. An actuator causes the first and second fluid compositions to be dispensed from the dispensers and mixed by flowing the first and second fluid compositions through a static mixer. The first and second fluid compositions are dispensed from the fluid delivery port as a fluid mixture that reacts in situ to form a nonfluent closure composition adjacent the vessel puncture site.
