GREFFE VASCULAIRE SYNTHETIQUE, PROCEDE DE PREPARATION D'UNE TELLE GREFFE ENDUITE DE COLLAGENE ET ETANCHE AU SANG ET BOUILLIE DE FIBRILLES DE COLLAGENE POUR SA PREPARATION

摘要

A collagen-coated vascular graft includes a porous synthetic vascular graft substrate formed by knitting or weaving with at least three layers of dispersed collagen fibrils. Plasticizers are incorporated into the collagen slurry before application and the slurry is applied in separate coatings by massage and flow through techniques, cross-linked by exposure to formaldhyde vapor and dried.
