Abstract

A stent (10) includes a plurality of annular expanding members (11) arranged a predetermined distance apart from each other in the axial direction of the stent (10) and each formed of a waved element (111), and a plurality of waved connecting members (12) connecting the ridges (M) and/or bottoms (V) of the waved elements (111) of adjacent annular expanding members (11). The plural annular expanding members (12) are arranged in the axial direction of the stent (10) such that no substantial phase difference exists between the waves of the waved element (11). Each waved connecting member (12) has a plurality of waves including a wave positioned in the clearance between the adjacent annular expanding members (11) and having an amplitude larger than that of the other wave. Also disclosed is a stent in which the expanding member is formed of a waved element arranged to surround spirally the longitudinal axis of the stent.
