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.
