Abstract
Systems and methods convey a closure material into a catheter, e.g., to seal a puncture site in a blood vessel. The closure material comprises a mixture of first and second components, which, upon mixing, undergo a reaction to form solid closure material composition. The first component may be a lyophilized polyethylene glycol (PEG) material contained within a vial. The second component may be a buffered albumin solution plus water contained within a syringe. An applicator provides easy and effective mixing of the components and delivery of the mixture to the puncture site.
