<p>A novel vascular graft comprises a flexible elongate tube of polymeric material having an internal porous surface and a network of interconnected interstitial pores below the surface in fluid flow communication with the surface pores. Tissue forms a smooth thin adherent coating of self-determining thickness on the porous surface making it resistant to the formation of the blood clots normally associated with the presence of foreign bodies in the bloodstream.</p> |
