摘要：
PROBLEM TO BE SOLVED: To provide a reinforcement member of an artificial blood vessel preventing the artificial blood vessel from being damaged by a blood flow pressure and from being occluded by kinking.SOLUTION: An artificial blood vessel 100 includes a reinforcement sheath 120 (a reinforcement member) formed by braiding (circular knitting) fibers composed of bioabsorbable materials into a cylindrical shape, at an outer peripheral side of a hollow cylindrical artificial blood vessel body 110 formed of bioabsorbable materials. The reinforcement sheath 120 includes a section line 122 formed by circularly knitting fibers into a cylindrical shape and extending along the longitudinal direction of the artificial blood vessel body 110 to the full length of the reinforcement sheath 120. The section line 122 is expanded in a direction of expanding the diameter of the artificial blood vessel body 110 so as to cover the artificial blood vessel body 110.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】血流の圧力によって人工血管が破損したりキンキングによって人工血管が閉塞したりすることのない人工血管の補強部材を提供する。【解決手段】人工血管100は、生体吸収性材料からなる中空円筒形状の人工血管本体110の外周側に、生体吸収性材料からなる繊維を円筒状に編成(丸編み)した補強シース120(補強部材)を備える。この補強シース120は、繊維を円筒状に丸編みして、人工血管本体110の長手方向に沿って補強シース120の全長に及ぶ切断線122を備え、人工血管本体110の径が広がる方向へ切断線122を拡張させて人工血管本体110を覆うように設けられる。【選択図】図1
