Device for handling an 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.

- 2. An appliance to be implanted comprising two appliances, each of which comprises a front end wire ring, a rear end wire ring arranged facing to the front end wire ring, a tubular cover which connects the front and rear end wire rings and an intermediate wire ring arranged between the front an rear end wire rings, wherein each of the wire rings is given flexibly foldable elasticity, and characterized by that the front end wire ring of the appliance arranged downstream locates in front of the rear end wire ring of the appliance arranged upstream so that the appliances are connected with each other partially overlapped at an adjacent position.
- 4. A device for handling an appliance to be implanted comprising a guide pipe which has a valve at a base end thereof and a device for transporting an appliance which is at least twice as long as the guide pipe and which can urge the appliance to be implanted rearward with the front tip thereof engaging with a side of a rear end of the appliance to be implanted and characterized by that a front tip of the device for transporting the appliance is inserted into the guide pipe through a hole provided on the valve by being pushed to open the hole with making use of elasticity of the hole and the front tip thereof is introduced to be led out of the guide pipe from the front end thereof so as to be engaged with the appliance to be implanted, and a base end of the device for transporting the appliance is turned down and pushed to be inserted into the guide pipe through other hole provided on the valve so as to open the hole with resisting elasticity of the hole and introduced to be led out of the guide pipe from the front end thereof.
