ABSTRACT:
A collagen impregnated synthetic vascular graft including a synthetic vascular graft substrate and cross-linked collagen fibril is formed by depositing an aqueous slurry of collagen fibrils in the lumen of the graft and massaging to insure intimate mixing of the fibrils into the porous structure of the substrate. After massaging, the collagen is dried and cross-linked. Repeated applications and massaging and drying further reduce porosity of the graft.
