Abstract
A woven tubing for use in a stent type blood vascular prosthesis, using a monofilament having a flattening in the range of 1.2-5.0 and a size in the range of 11-250 dtex in at least part of the warp and a stent type blood vascular prosthesis using the tubing are disclosed. 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 and allows prevention of the inflow of blood into the lesion.
