Abstract:
The invention is directed to a method including the steps of providing at least one layer of unlaminated elastin or unlaminated elastin-based materials or unlaminated tropoelastin materials. Then, the unlaminated elastin or unlaminated elastin-based materials or unlaminated tropoelastin materials is subjected to heating and pressing steps. The pressing step of the present invention is preferably conducted in the presence of steam. The laminated elastin or laminated elastin-based materials or laminated tropoelastin materials preferably comprises a multi-layer composite material. Typically, the step of adhering with an adhesive material the laminated elastin or laminated elastin-based materials or laminated tropoelastin materials is employed in order to achieve a water-tight engagement with the tissue substrate. A biogradable cyanocrylate glue is generally used in order to achieve quick and easy way to secure the patch in place and provide watertight fusion instantly. Preferably, the adhesive material comprises an alkoxy alkyl cyanoacrylate material.
