Appliance to be implanted and a device for handling the appliance to be implanted
First Claim
1. An appliance to be implanted comprising a front end wire ring, rear end wire rings arranged facing to the front end wire ring, a bifurcated tubular cover which connects the front end wire ring and the rear end wire rings, and an intermediate wire ring arranged between the front end rear end wire rings, in which each of the wire rings is given flexibly foldable elasticity, and characterized by that each of the wire rings can be folded into a wavy shape with forming forwardly directed peaks and the bottoms of forwardly directed valleys alternatively and repeatedly.

Abstract
The artificial blood vessel A comprises a front end wire ring 101, a rear end wire ring 102 arranged facing to the front end wire ring 101, a tubular cover 7 which connects the end wire rings 101, 102, and a plurality of intermediate wire rings 12 arranged spaced apart from each other between the front end wire ring 101 and the rear end wire ring 102. Each of the front end wire ring 101, the rear end wire ring 102 and the intermediate wire rings 12 are given flexibly foldable elasticity. The circumference of the front end wire ring 101 is equally divided into four by dividing points 411, 421, 431, 441. Hooking means 13 are formed for a front pull string to be passed through at the dividing points 411, 431. The circumference of the intermediate wire ring 12 is fixed to the tubular cover 7 by suturing or with adhesive at the positions 513, 523, 533, 543 which correspond to the midpoint 511 between the dividing points 411, 421, the midpoint 521 between the dividing points 421, 431, the midpoint 531 between the dividing points 431, 441, and the midpoint 541 between the dividing points 441, 411.
