| 摘要 |
An easy-to-produce and mechanically strong tube of an implantable graft prosthesis has been developed which is manufactured in any desired length, wall thickness, or diameter. The construct produced by t he method of the invention may be used as grafts for arteries, vein, ureters, urethras, shunts, or in any application where a compliant, tissue-compatible tube is needed. The manufacture of the graft prosthesis generally involves wrapping multiple sheets of a purified, collag en- based matrix structure around a mandrel, compressing and drying the tissue on the mandrel before removing the construct for eventual use. |
