COMPOSITE ARTIFICIAL BLOOD VESSEL.

摘要

An artificial blood vessel comprising a tube made from a porous synthetic polymer and, covalently bonded to the surface of the tube via a hydroxyl, carboxyl, epoxy or amino group, a protein or peptide having an activity of cell adhesion and growth. It is possible to form a stable composite of a substance having a tissue inducing activity uniformly on the surface of the porous polymer material through covalent bonds without deforming the material, to form the tunica intima rapidly without inducing primary thrombus, and to maintain the formed tunica stably for long.
