A method of tissue repair is provided using a biocompatible nonimmunogenic adhesive composition. The adhesive composition comprises collagen and a plurality of crosslinkable components having reactive functional groups thereon, with the functional groups selected so as to enable inter-reaction between the components, i.e., crosslinking. Kits for use in carrying out the method of the invention are also provided, as are pretreated surgically acceptable patches that have been coated with the aforementioned adhesive composition.

1. A mesh for use in the repair of herniated tissue comprising a mesh and a coating composition including: (a) a naturally occurring hydrophilic polymer selected from proteins, polysaccharides, and glycosaminoglycans, wherein the naturally occurring hydrophilic polymer is not methylated collagen;(b) a first synthetic polymer having m nucleophilic groups, wherein m≧2;(c) a second synthetic polymer having n electrophilic groups capable of reaction with the m nucleophilic groups to form covalent bonds, wherein n≧2; andwherein each of the first synthetic polymer and the second synthetic polymer is poly (alkylene oxide) and crosslinking of the coating composition results in a biocompatible, crosslinked matrix. 2. The mesh of claim 1, wherein the first synthetic polymer and the second synthetic polymer are hydrophilic. 3. The mesh of claim 1, wherein m+n is 5 or more. 4. The mesh of claim 1, wherein each of the first synthetic polymer and the second synthetic polymer is nonimmunogenic. 5. The mesh of claim 1, wherein the naturally occurring hydrophilic polymer is selected from nonfibrillar collagen, succinylated collagen, fibrillar collagen, denatured collagen and combinations thereof. 6. The mesh of claim 5, wherein the nonfibrillar collagen is selected from type IV collagen, type VI collagen, and type VII collagen. 7. The mesh of claim 2, wherein the first synthetic polymer and the second synthetic polymer are polyalkylene oxides. 8. The mesh of claim 7, wherein the first synthetic polymer and the second synthetic polymer are polyethylene glycol. 9. The mesh of claim 1, wherein the nucleophilic groups of the first synthetic polymer can be the same or different and are —NH2, —SH, —OH, —PH2, or —CO—NH—NH2. 10. The mesh of claim 1, wherein the coating composition further comprises a biologically active agent. 11. The mesh of claim 1, wherein the electrophilic groups are a succinimidyl ester group, a succinimidyl carbonate group, and a maleimidyl group, —COOH, —CHO, —N═C═O or —SO2CH—CH2.
