On the lumen aspect of the artificial vascular

摘要

PURPOSE:To provide an artificial blood vessel capable of exhibiting high operability over a long period even with a small bore immobilizing elastin to the inside cavity surface of the artificial blood vessel in such a manner that the elastin suppresses the clotting activity of blood on the material surface and simultaneously suppresses the excess growth of cells and tissues so as to suppress the thickening of the internal membrane of an anastomosis part. CONSTITUTION:The water-soluble elastin is coacervated directly on the inside cavity surface of an artificial blood vessel base material consisting of a synthetic resin after gelation or collagen is applied thereon and is fixed by a cross-linking agent and thereafter this elastic is fixed by a cross-linking agent.
