Abstract
Abstract The artificial blood vessel A comprises a front end wire ring 10 1 , a rear end wire ring 10 2 arranged facing to the front end wire ring 10 1 , a tubular cover 7 which connects the end wire rings 10 1 , 10 2 , and a plurality of intermediate wire rings 12 arranged spaced apart from each other between the front end wire ring 10 1 and the rear end wire ring 10 2 . Each of the front end wire ring 10 1 , the rear end wire ring 10 2 and the intermediate wire rings 12 are given flexibly foldable elasticity. The circumference of the front end wire ring 10 1 is equally divided into four by dividing points 41 1 , 42 1 , 43 1 , 44 1 . Hooking means 13 are formed for a front pull string to be passed through at the dividing points 41 1 , 43 1 . The circumference of the intermediate wire ring 12 is fixed to the tubular cover 7 by suturing or with adhesive at the positions 51 3 , 52 3 , 53 3 , 54 3 which correspond to the midpoint 51 1 between the dividing points 41 1 , 42 1 , the midpoint 52 1 between the dividing points 42 1 , 43 1 , the midpoint 53 1 between the dividing points 43 1 , 44 1 , and the midpoint 54 1 between the dividing points 44 1 , 41 1 .
