Abstract
A biocompatible and biodegradable barrier material is applied to a tissue region, e.g., to seal a vascular puncture site. The barrier material comprises a compound, which is chemically cross-linked without use of an enzyme to form a non-liquid mechanical matrix. The compound preferably includes a protein comprising recombinant or natural serum albumin, which is mixed with a polymer that comprises poly(ethylene) glycol (PEG), and, most preferably, a multi-armed PEG polymer.
