STENT

摘要

PROBLEM TO BE SOLVED: To provide a stent uniformly expandable axially and radially, being pertinently used even for a curved blood vessel. SOLUTION: A stent 1 formed approximately like a tubular body and radially stretchable from the inside of the tubular body is constructed so that an approximately corrugated constituent 6 long in the axial direction of the stent 1 and having a center opening is connected to both sides of an approximately circular constituent 7 having a center opening for forming a constituent 2 and a plurality of the constituents 2 are arranged so as to surround the center axis of the stent 1. The adjacent parts of the constituents 7 are connected via a connecting part 3 for forming an annular unit 4 and a plurality of annular units 4 are extended along the axial direction of the stent 1. The annular units 4 are connected to each other at least at one position via a connecting part 5 and at least one of the approximately circular constituents 7 to constitute the annular unit 4 is connected to another approximately circular constituent 7 via a pair of a connecting parts 8.
