Abstract

Abstract An artificial body vessel to be inserted into a human organ is collapsed and introduced into a catheter, which is brought to a required position in the human organ, where the artificial body vessel is released therefrom. A pair of foldable, elastic wire rings 10 are provided at the opposite ends of the artificial body vessel. A plurality of connecting wire rings bridge the end wire rings 10. A plurality of intermediate wire rings 12 bind and keep the connecting wire rings 11 transformed to a generally elliptical shape. The end wire rings 10, the intermediate wire rings 12 and the connecting wire rings 11 are folded thereby to collapse the artificial body vessel 7. The collapsed artificial body vessel 7 is inserted into a catheter. At the objective position of the blood vessel the artificial body vessel 7 is released, so that the resiliency of the end wire rings 10, the intermediate wire rings 12 and the connecting wire rings 11 restores the artificial body vessel 7 to its original tubular shape.
