Compliant tissue sealants
First Claim
1. A compliant polymeric material on a surface, wherein the material is formed by the polymerization of an aqueous solution or suspension of a polymerizable monomer in contact with the surface,wherein the polymerization reaction occurs between at least one first reactant selected from the group consisting of an amine, an alcohol, and a thiol and at least one second reactant selected from the group consisting of an isocyanate, an isothiolcyanate, an aldehyde, an epoxide, an oxirane, and a cyclic amine, wherein at least one reactant is covalently attached to the monomer, and wherein the compliant polymeric material has an adherence to the surface of at least 20 grams per square centimeter.

Abstract
An improved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, the system is compliant, in that it is capable of conforming to the three dimensional structure of a tissue surface as the tissue bends and deforms during healing processes. The barrier or drug delivery systems is formed as a polymeric coating on tissue surfaces by applied a polymerizable monomer to the surface, and then polymerizing the monomer. The polymerized compliant coating preferably is biodegradable and biocompatible, and can be designed with selected properties of compliancy and elasticity for different surgical and therapeutic applications.
