Abstract
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.
