A collagen impregnated vascular graft including drug materials complexed with the collagen to be released slowly from the graft following implant. The graft is a porous synthetic vascular graft substrate having collagen fixed to the graft substrate and cross-linking the collagen in situ to render th ...
A collagen-impregnated vascular graft includes a porous synthetic vascular graft substrate formed by knitting or weaving with at least three applications of dispersed collagen fibrils. Plasticizers are incorporated into the collagen slurry before application and the slurry is applied in separate tre ...
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 ...
