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.

Claims (6)

1 . A cover stent comprising:

a mesh tube knitted into a tube shape by a wire, the wire including a first bending portion protruding toward a first end portion in a longitudinal direction of the tube shape and a second bending portion protruding toward a second end portion opposite to the first end portion in the longitudinal direction, the first bending portion and the second bending portion intersecting each other at an intersection of the first bending portion and the second bending portion by being twisted once;

a cover that covers outside or inside of the mesh tube; and

at least one restricting member connected to the cover with a space, the wire in at least one of the first bending portion and the second bending portion being movably inserted into the space along a surface of the cover,

wherein, the first bending portion is closer to the cover than the second bending portion at the intersection; and

the restricting member is disposed in a vicinity of the intersection where the first bending portion and the second bending portion intersect with each other, and the restricting member is only disposed on the first bending portion located closer to the cover among the first and second bending portions located at the intersection.
