ABSTRACT:
A delivery device applies a biocompatible and biodegradable barrier material to a tissue region, e.g., to seal a vascular puncture site. The material comprises two liquid components, which are pre-packaged in individual dispensers. Upon mixing, the liquid components cross-link to create a barrier matrix. A holder attaches to the delivery device. The holder mutually supports the first and second dispensers while the protein solution and polymer solution are conveyed from the dispensers into a fluid delivery channel. The protein and polymer solutions mix as a result of flow through the channel.
