Artificial blood vessel

摘要

An artificial blood vessel made of a tube formed from expanded polytetrafluoroethylene comprising fibrils and nodes connecting fibrils, in which the inner surface of said tube and the surfaces of pores in a layer portion extending from the inner surface of said tube to a depth of at least 5 % in a radial direction from said inner surface are made hydrophilic, and a tissue-inducing substance which is immobilized on said inner surface and said surfaces of pores which are made hydrophilic, which has a good patency ratio for a long time.
