PROBLEM TO BE SOLVED: To provide a stent having a novel structure, capable of achieving in a higher degree, a characteristic required for the stent, by providing partially an over-deformation region.SOLUTION: In a stent including such a self-extension area 56 that skeletons 52, 54 are deformed into a shape set beforehand by super elasticity, a part deviated to the axial direction from the self-extension area 56 in the skeletons 52, 54 is used as an over-deformation region 58 deformable larger than the self-extension area 56, and thereby a deformed shape can be set with a larger degree of freedom.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2020,JPO&INPIT【課題】一部に過変形領域を設けることで、ステントに要求される特性をより高度に実現し得る、新規な構造のステントを提供すること。【解決手段】骨格５２，５４が超弾性によって予め設定された形状に変形する自己拡張領域５６を備えると共に、骨格５２，５４における自己拡張領域５６を軸方向に外れた部分が、自己拡張領域５６よりも大きく変形可能とされた過変形領域５８とすることで、変形後の形状をより大きな自由度で設定することができる。【選択図】図６
