The arterial vessel is made of a microporous membrane having pores which are filled with a permeable gel or which are closed over by a thin porous layer. A monolayer of endothelial cells is provided on the internal surface for exposure to the blood flow and smooth muscle cells are layered on the outer surface for increasing the viability of the live cells on the membrane and to impart elasticity. A support structure formed of a braided construction of monofilaments of inert material can be provided to limit dilation of the vessel.

Artificial vessel

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.
