SELF-EXPANDABLE INTERNAL PLACEMENT STENT

摘要

PROBLEM TO BE SOLVED: To provide a self-expandable in vivo indwelling stent which has the proper shape of a zigzag waveform annular body and by which a distortion is not concentrated in a connection part.

SOLUTION: The stent 1 includes: a plurality of annular bodies 2; and the connection parts 3 where the annular bodies 2 are connected in a state where the bodies 2 are arranged in the axial direction of the stent. The circular body 2 comprises: multiple supporter parts 21 to be nearly in parallel with the center axis of the stent when the diameter of the stent is reduced; and loop parts 22 for connecting the adjacent supporter parts. The connection parts 3 are generally circularly bent and the width (E) of the connection part is larger than the width (F) of the supporter part 21.
