Abstract
The invention relates to a vessel prosthesis or patch, made from a biocompatible polymer with microporous, finely-fibrillated structure and a method for improving the e-modulus of said vessel prostheses or patches. According to the invention, the vessel prostheses or patches are subjected to a full stretching (extension) with a degree of extension between 30% and 250% and subsequent restoration.
Claims10
A method of making a vascular prosthesis or tissue web of biocompatible polyurethane, polyamide, polysulfone, polyester, isotactic polypropylene, polynitrile or polyvinylchloride, mixtures thereof or their copolymers, with a microporous finely fibular structure, characterized by a definitive stretching (extension) with a degree of extension between 30% and 150%, and subsequent relaxation.
