Abstract: A stent formed by weaving a wire, includes: a plurality of straight line intersection portions at which straight line portions intersect with each other; and a plurality of engagement portions at which a mountain-shaped bent portion that is bent toward a side in a first direction, which is one side in an axial direction, and becomes convex, and a valley-shaped bent portion that is bent toward a side in a second direction, which is the other side in the axial direction, and becomes convex intersect with each other. The plurality of straight line intersection portions have a first straight line intersection portion and a second straight line intersection portion. The plurality of engagement portions have a first engagement portion, a second engagement portion, a third engagement portion, and a fifth engagement portion. The first engagement portion and the second engagement portion are disposed at different positions in the axial direction.

Abstract: A stent formed by weaving wires includes: a plurality of straight-line crossing portions, which are formed by crossing at least two straight-line portions of the wires and are arranged adjacent to each other in a circumferential direction of the stent; and a plurality of interlocking portions configured by intersecting a peak-shaped bent portion, in which the wire is bent in a first direction side which is one side of a longitudinal axis direction of the stent and becomes convex, and a valley-shaped bent portion, in which the wire is bent in a second direction side which is the other side of the longitudinal axis direction and becomes convex, and arranged so as to be adjacent to each other in the circumferential direction of the stent, wherein the interlocking portions and the straight-line crossing portions are arranged alternately in the longitudinal axis direction.

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.
