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