Abstract
An artificial blood vessel comprising a tube of a porous synthetic polymer on a surface of which a protein or a peptide having cell adhesion and growth functions is covalently bonded through hydroxyl groups, carboxyl groups, epoxy groups or amino groups. Its surface is uniformly composited stably with the material having the tissue induction function by the covalent bond without deforming a shape of the porous synthetic polymer material. Therefore, no initial thrombus is induced, and the intima is quickly formed and remains stably for a long time.
