Abstract:
An artificial blood vessel is used that has, alternating in the extension direction D2 of a weft 2: a first region R1 in which a warp 1 and the weft 2 are woven in a plain weave; a second region R2 having a second-region-side first portion R21 in which the warp 1 crosses over a plurality of wefts 2, and a second-region-side second portion R22 in which the warp 1 extends over one weft 2; and a third region R3 having a third-region-side first portion R31 in which the warp 1 crosses over a plurality of wefts 2, and a third-region-side second portion R32 in which the warp 1 extends over one weft 2, the second-region-side first portion R21 adjoining the third-region-side second portion R32 in the extension direction D2 of the weft 2, the second-region-side second portion R22 adjoining the third-region-side first portion R31 in the extension direction D2 of the weft 2, and the warp 1 being configured from a multifilament thread, whereby it is possible to provide an artificial blood vessel that has a weave structure having as a part a plain weave region, in which fiber gaps occurring in the plain weave region are sealed and blood leakage resistance is improved.
