Abstract:
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 having a wavy line pattern and connection elements that connect the annular bodies. The wavy line pattern is formed by V-shaped elements, in which two leg parts are joined by an apex part, being connected in a state where the apex parts alternately face opposite directions in an axial direction. A bending direction of one end part of the connection element and a bending direction of another end part thereof are opposite to one another. The end part of the connection element is connected to a portion other than the apex part of the V-shaped element of the adjacent annular body with the end part of the connection element being extended in a direction different from the direction in which the leg part extends. When viewed in a radial direction (RD), the direction in which an intermediate part of the connection element extends is oblique to the axial direction (LD). One of the two leg parts extends along the intermediate part of the connection element.
