Abstract
Provided is a stent to be inserted into an in vivo organ having a tubular structure that allows a degree of freedom in design and excellent mechanical flexibility. A cylinder-shaped stent is inserted to be placed and used in the inner cavity of an in vivo tubular organ, wherein: the wall of the stent has a planar mesh pattern filled with a plurality of closed cells being adjacent to each other and having congruent shapes; the closed cells have point-symmetric parallel hexagonal shapes; all closed cells circumferentially adjacent to each other are congruent and similar in shape; two closed cells adjacent to each other sharing different sides form a substantially V-shaped member; and the vertex of each folded part in the substantially V-shaped member points to the circumferential direction.
