摘要:
Provided is a flexible stent in which a free end strut does not tend to project outside when the stent is bent and shortening can be suppressed at the time of expansion of the stent. The flexible stent includes annular bodies (13) having a wavy line pattern and connection elements (15) that connect the annular bodies (13). The wavy line pattern is formed by V-shaped elements (17), in which two leg parts (171) are joined by an apex part (172), being connected in a state where the apex parts (172) alternately face opposite directions in an axial direction. A bending direction of one end part (151) of the connection element (15) and a bending direction of another end part (151) thereof are opposite to one another. The end part (151) of the connection element (15) is connected to a portion other than the apex part (172) of the V-shaped element (17) of the adjacent annular body (13) with the end part (151) of the connection element (15) being extended in a direction different from the direction in which the leg part (171) extends. When viewed in a radial direction (RD), the direction in which an intermediate part (152) of the connection element extends is oblique to the axial direction (LD). One of the two leg parts (171) extends along the intermediate part (152) of the connection element (15).
