Abstract
A method of production of a tissue sealing patch is disclosed. The method comprises casting a polymer film from a biocompatible polyethylene glycol-caprolactone-lactide triblock copolymer (PECALA); softening the polymer film; placing a powdered tissue sealant material on a surface of said polymer film; and, pressing said polymer film to at least partially incorporate the sealant material into said surface of said polymer film. In some embodiments of the invention, the polymer film is created by heating and evacuating a work surface; applying a solution of PECALA to said work surface; adjusting a polymer blade to a predetermined height above said work surface; spreading said solution of PECALA over said work surface with said polymer blade; and evaporating said solvent. The PECALA preferably comprises PEG-CL-LA units connected by urethane linkages, PEG having a molecular weight of between 3000 and 3500 amu, and a CL:LA:PEG ratio of 34:2:1.
