And provides excellent mechanical flexibility has a degree of freedom in design, a stent for insertion into engine having a tubular structure of a living body. Used in interposed lumen of the tubular organ of a living body, there is provided a stent having a cylindrical shape, the wall of the stent mesh having a structure in which closed cells having a shape congruent adjacent a plurality of the tessellated and a pattern has a parallel hexagonal shape point-symmetrical, the shape of the closed cell adjacent in the circumferential direction on a similar and congruent all the closed cells, the two adjacent Share sides different closed cell has a substantially V-shape, the apex of the bent portion of the substantially V-shape is directed to the circumferential direction.設計の自由度を有し力学的柔軟性に優れた、生体の管状構造を有する機関に挿入するためのステントを提供する。生体の管状器官の内腔部に挿置して使用される、円筒形状を有するステントであって、該ステントの壁は複数の隣接する合同な形状のクローズドセルが平面充填された構造を有するメッシュパターンを有し、該クローズドセルは、点対称な平行六辺形状を有し、円周方向上に隣接するクローズドセルの形状はすべて合同かつ相似であり、異なる辺を共有して隣合う2つのクローズドセルが略V字型形状を有し、略V字型形状の折れ曲がり部分の頂点が円周方向を向いている。
