Document Type and Number:
WIPO Patent Application WO/2023/149582
Kind Code:
A1
Abstract:
An artificial blood vessel according to the present invention has: warp filaments 1 which extend in the axial direction and in which ridge sections M and valley sections V are alternately formed in the axial direction; and weft filaments 2 which extend in the circumferential direction of an artificial blood vessel VE. The warp filaments 1 have a structure in which peak sections Mt1, Mt2 of a pair of neighboring ridge sections M in the axial direction are aligned at positions in the circumferential direction, and positions at bottom section Vb of the valley section V between the pair of the ridge sections M extend in an undulating manner if the artificial blood vessel VE is viewed in the radial direction so as to be offset in the circumferential direction with respect to the positions of the peak sections Mt1, Mt2 of the pair of the ridge sections M. By having this structure, an artificial blood vessel which does not readily fray when the artificial blood vessel is cut can be provided.
