  • Woven tubing for stent type blood vascular prosthesis and stent type blood vascular prosthesis using the tubing
    Patent number: 7063721
    Abstract: 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.
    Type: Grant
    Filed: March 18, 2003
    Date of Patent: June 20, 2006
    Assignees: Terumo Kabushiki Kaisha, Seiren Co., Ltd.

  • Woven tubing for stent type blood vascular prosthesis and stent type blood vascular prosthesis using the tubing
    Patent number: 7000649
    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.
