As for sutento, each circumferential section has alternate apex and bottom, the plural corrugated circumferential sections The plural lengthwise expansion sections which connect the plural corrugated circumferential sections and, it has. Each of the plural lengthwise expansion sections includes the second lengthwise expansion support which slips in circumferential direction the first lengthwise expansion support, and vis-a-vis the first lengthwise expansion support. The first lengthwise expansion support and the second lengthwise expansion support is connected mutually by the terminal area. Just first distance has alienated the first lengthwise expansion support which it adjoins to circumferential direction in the lengthwise expansion section which it adjoins to the circumferential direction of pair in circumferential direction, just second distance has alienated the second lengthwise expansion support which it adjoins to circumferential direction in the lengthwise expansion section which it adjoins to the circumferential direction of pair in circumferential direction. First distance is larger than second distance. This sutento, while the gap and other problems from collision and tubular constitution (it is stated) beforehand preventing or lightening to this bill, has the balance whose adjusted characteristic and flexibiility are very desirable.< Selective figure > Figure 8ステントは、各円周部が交互の頂部および底部を備える、複数の波形円周部と;複数の波形円周部を接続する複数の縦方向伸長部と、を備える。複数の縦方向伸長部の各々は、第一縦方向伸長支柱、および第一縦方向伸長支柱に対して円周方向にずれた第二縦方向伸長支柱を含む。第一縦方向伸長支柱および第二縦方向伸長支柱は、接続部によって相互接続されている。一対の円周方向に隣接する縦方向伸長部において円周方向に隣接する第一縦方向伸長支柱は第一距離だけ円周方向に離間しており、一対の円周方向に隣接する縦方向伸長部において円周方向に隣接する第二縦方向伸長支柱は第二距離だけ円周方向に離間している。第一距離は第二距離よりも大きい。本ステントは、衝突、管状構成からのずれ、その他の問題(本明細書に記載される)を未然に防止または軽減しながら、順応性と可撓性との非常に望ましい均衡を有する。【選択図】 図8
