1. A blood vessel prosthesis comprising a tubular support member of an at least partially non-resorbable material without adverse tissue reaction, and at least one inner wall member of a resorbable material without adverse tissue reaction supported by said tubular member and forming a substantially concentric inner wall structure thereto, said inner wall structure being sufficiently porous to permit the passage of blood cells, such as erythrocytes and thrombocytes, through the free inner surface and into at least a substantial part of the thickness thereof, thereby providing a support inside said tubular support member for the formation of a layer of thrombotic material whereby an endothelium coated muscle layer is formed on said tubular support member.
