Patent ID: 7700147

Claim:
A method for treating polyester artificial prostheses, said method comprising: (i) a first step of preparing a polyester surface of said prostheses in a solvent consisting of hexane that does not cause the polyester surface to swell, and (ii) grafting one or more biologically active polymers or copolymers to the polyester surface of said prostheses prepared in step (i), wherein said grafting step consists of achieving peroxidation of the polymer surface by ozonation followed by a radical polymerisation of a solution of at least one monomer, wherein, said method achieves biomimetic functionalization so that the prostheses is adapted to mimic living materials and facilitate anchoring and development of fibroblasts after implantation of said prostheses, said method optionally comprises one or more washings with ethyl ether after the step of preparing in the solvent in step (i), and said polyester artificial prostheses comprises a polyethylene terephtalate material.
