Biological tissue adhesion

Abstract

The invention provides a method for the application of gelatin-resorcinol aldehyde glue to a surface, wherein a solution of gelatin-resorcinol is applied to the surface to obtain a gelatin-resorcinol coated surface. Subsequently, a solution of an aldehyde is aerosolized onto the gelatin-resorcinol coated surface. The mixture of gelatin-resorcinol and the aldehyde is then allowed to polymerize on the surface. The methods of the invention may be conveniently and efficiently used to apply gelatin-resorcinol aldehyde glue to high porosity vascular prostheses, either before or after implantation, to provide improved hemostasis. The aldehydes that may be utilized according to the methods of the invention may include formaldehyde, glutaraldehyde, or a combination thereof In one embodiment of the invention, the gelatin-resorcinol aldehyde glue may be conveniently provided in a kit that includes (a) a first container of a gelatin-resorcinol solution and (b) a second container of a solution of an aldehyde, the second container including means for aerosolizing the aldehyde solution. The methods of the invention may be used for the application of gelatin-resorcinol aldehyde glue in a wide variety of surgical procedures.
