Abstract: A cover stent includes: a mesh tube knitted into a tube by a wire including a first bending portion protruding toward a first end portion in a longitudinal direction of the tube and a second bending portion protruding toward a second end portion opposite to the first end portion in the longitudinal direction, the first and second bending portions intersecting each other by being twisted once; a cover covering outside or inside of the mesh tube; and a restricting member connected to the cover with a space, the wire in at least one of the first and second bending portions being movably inserted into the space along a surface of the cover. The mesh tube is connected to the cover by the restricting member so that the first and second bending portions can move relative to each other along the surface in the longitudinal direction.

Abstract: A stent includes a first tubular unit that has a cylindrical tubular shape and a mesh circumferential surface; and a second tubular unit that has a cylindrical tubular shape and a mesh circumferential surface, and is connected to the first tubular unit in a longitudinal axis direction of the stent. The first tubular unit has a first-first direction bent portion which is bent to be convex toward the first direction side that is one side of the longitudinal axis direction, the second tubular unit has a second-second direction bent portion which is bent to be convex toward the second direction side that is the other side of the longitudinal axis direction, and the first-first direction bent portion and the second-second direction bent portion form a first connecting portion that is connected so as to be relatively movable.

Abstract: Provided is a covered stent manufacturing method including: disposing an inner cover inside a stent body having a mesh structure formed by knitting wires, the stent body having engagement portions, each of which is formed by hooking two bent portions of the wires with each other; disposing an outer cover outside the stent body; forming a slack portion that expands in a radial direction of the stent body in at least one of the covers, the slack portion creating slack that allows movements of the two bent portions in a longitudinal direction and the radial direction of the stent body in at least one of the covers; and joining the covers with each other in regions on an inner side of the mesh of the mesh structure.
