Abstract
Abstract A collagen-coated impregnated vascular graft is made by treating a porous synthetic vascular graft substrate (formed e.g. by knitting or weaving) at least three times with collagen fibrils, cross-linking e.g. by exposure to formaldhyde vapor) and drying. Treatment is by an aqueous slurry containing 0.5-5% collagen fibrils and 4-12% of a biocompatible plasticiser.
