PROBLEM TO BE SOLVED: To make it possible to surely maintain an expanded state without a change in the length of an axial length in spite of expansion and without expansion to the size larger than a prescribed size in spite of action of more than necessary expansion force. SOLUTION: Wire-shaped members 32 are formed to a corrugated shape consisting of bent parts of a U shape continuous with each other and are provided with detaining parts 33, 34 consisting of small curved parts in respective angle parts. At least >=3 pieces of such wire-shaped members 32 are arrayed in parallel and the corresponding bent parts of the U shape adjacent to each other are entangled with each other to form a net-like body 35. The netlike body 35 is bent to a cylindrical shape and both end edges are connected, by which the stent 31 is constituted. |
