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.
Claims19
A woven tubing for use in a stent blood vascular prosthesis, comprising:
- a multifilament warp element formed of only two to five single filaments;
- and
- a weft element;
- wherein the warp element and weft element are woven in such a manner that all of the single filaments forming the multifilament warp element are disposed in a single line.
A woven tubing for use in a stent blood vascular prosthesis, comprising:
- a plurality of woven warp elements and weft elements;
- at least apart-of one of the warp elements being a multifilament warp element formed of at least two single filaments and not more than five single filaments;
- and
- the warp elements and the weft elements being woven in such a manner that all of the single filaments of the at least one multifilament warp element are disposed in a single line between the weft elements.
