Abstract
A prosthesis for replacing parts of arteries and other blood vessels preferably has an inner tube suitable for use as a vascular graft in combination with external longitudinal ribs and a surrounding wrap which provides radial and longitudinal strength and resistance to kinking. The ribs separate the wrap from the inner tube, providing spaces between the wrap and tube to allow the tube to expand and contact, thus promoting isocompliance of the prosthesis with natural blood vessels.
