Abstract: A stent comprises a wire that is woven into a tubular fence forming a stent body, a plurality of tubular units connected around a longitudinal center axis of the stent body, and a plurality of connecting locations configured to connect adjacent ones of the plurality of tubular units and arranged along a plurality of circumferences with respect to the longitudinal center axis of the stent body. The plurality of circumferences include a first circumference having a first radius and a second circumference having a second radius, and the first radius is different from the second radius in length.

Abstract: The stent having self-expandability, the stent including: a body part formed in a tubular shape by a wire; and a first locking part and a second locking part protruding outward in a radial direction of the body part and formed by the wire. A first angle formed by a protrusion direction of the first locking part and an axial direction of the body part is different from a second angle formed by a protrusion direction of the second locking part and the axial direction.
