A woven tubing for use in a stent type blood vascular prosthesis which
contains a multifilament formed of two five single filaments 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.
