Abstract
The artificial vessel has a membrane of at least semi-permeable bio-inert synthetic material with a monolayer of endothelial cells on the internal surface and a layer of smooth elastic fiber-generating muscle cells on the outer surface. The membrane may be made pore-less or may be made with a network of opened micropores filled with an aqueous gel to provide a smooth internal surface on which the endothelial cells may be coated.
