Abstract
A collapsible artificial blood vessel A comprises a flexible front end wire ring 101, a flexible rear end wire ring 102 arranged facing to the front end wire ring, a tubular cover 7 which connects the end wire rings, and a plurality of intermediate wire rings 12 arranged spaced apart from each other between the front end wire ring and the rear end wire ring. The circumference of the front end wire ring is equally divided into four segments by dividing points 411, 421, 431, 441. Hooks 13 are formed for a front pull string to be passed through at the dividing points 411, 431. The circumference of the intermediate wire rings are fixed to the tubular cover 7 by suturing or with adhesive at the positions 513, 523, 533 and 543. The device is collapsed for use by folding the wire rings and insertion of the device into a funnel tube.
