Temporarily stiffened mesh prostheses
First Claim
1. A medical prosthesis comprising a porous surgical mesh with one or more biodegradable or resorbable polymer coatings, wherein said one or more biodegradable or resorbable polymer coatings have been applied to said mesh without substantially altering a porosity of said porous surgical mesh, and wherein said medical prosthesis ameliorates or mitigates a soft tissue defect,wherein said one or more biodegradable or resorbable polymer coatings comprise one or more tyrosine-derived dipghenol monomer units.

Abstract
The present invention relates to medical prostheses and methods of manufacturing those devices. In particular, the prostheses are temporarily stiffened meshes with particular coatings to provide initial stiffness and thereby permit easier surgical handling for treatment or reconstruction of soft tissue defects. Preferred embodiments include surgical meshes coated with one or more biodegradable polymers that can act as a stiffening agent by coating the filaments or fibers of the mesh to temporarily immobilize the contact points of those filaments or fibers and/or by increasing the stiffness of the mesh by at least 1.1 times its original stiffness. The devices of the invention can also provide relief from various post-operative complications associated with their implantation, insertion or surgical use. By including biologically active agents and/or drugs in the coating, the devices provide prophylaxis for and can alleviate side effects or complications associated with the surgery or use of prostheses in general.
