This invention regards tubular sutento which is planted in body tube intracavity. sutento (1500), it possesses the cylindrical condition which decides the length direction axis, the proximal helical section (1506) with, the distal (2036) helical section (1507) with, the intermediate stiffening ring section between those sections (1520) with, includes. Proximity and the distal (2036) helical section respectively, the plural support components which are directed to length direction (1513), and lap the plural hinge components which are directed to direction (1154) it possesses, the hinge component, lap connecting the support component which it adjoins to direction, forms the band, the band, in order to form the plural helical winding parts, substantially helically, is wound the length direction axis as the center the distal (2036) helical section, in the direction which is opposite to the proximal helical section, is wound the length direction axis as the center. As for the intermediate stiffening ring section, the plural support components which are directed to length direction, and lap the plural hinge components which are directed to direction are included, the hinge component, lap connecting the support component which it adjoins to direction, forms the non edge ring.本発明は、身体管腔内に植え込まれる管状ステントに関する。ステント(1500)は、長さ方向軸を定める円筒形状を有し、近位螺旋状セクション(1506)と、遠位螺旋状セクション(1507)と、それらセクション間の中間リングセクション(1520)と、を含む。近位および遠位螺旋状セクションはそれぞれ、長さ方向に向けられた複数の支柱部材(1513)、および周方向に向けられた複数のヒンジ部材(1154)を有し、ヒンジ部材は、周方向に隣接する支柱部材を接続してバンドを形成し、バンドは、複数の螺旋状巻き部分を形成するように、実質的に螺旋状に、長さ方向軸を中心として巻かれ、遠位螺旋状セクションは、近位螺旋状セクションとは反対の方向に、長さ方向軸を中心として巻かれる。中間リングセクションは、長さ方向に向けられた複数の支柱部材、および周方向に向けられた複数のヒンジ部材を含み、ヒンジ部材は、周方向に隣接する支柱部材を接続して無端リングを形成する。
