Woven tubing for stent type blood vascular prosthesis and stent type blood vascular prosthesis using the tubing

摘要

A woven tubing (80) for use in a stent type blood vascular prosthesis which contains a multifilament formed of two-five single filaments (11) in at least part of warps and has the single filaments disposed in single lines, and a stent type blood vascular prosthesis using the woven tubing are described. The prosthesis combines a shape retaining property that is capable of maintaining its tubular shape without being crushed by the flow of blood with a high liquid tightness that is capable of reducing the leakage of blood to the exterior when implanted at the site of a lesion and allows prevention of the inflow of blood into the site of a lesion.
