Abstract
The stent of the present invention is a tubular member comprising annular members 1 arranged in a longitudinal direction thereof for keeping a body lumen open, and one or more connecting elements 2 for connecting longitudinally adjoining two annular members 1, 1 with one another. Each annular member 1 comprises first annular member elements 11 and second annular member elements 12 which are alternately jointed together in the circumferential direction of the annular member 1. The annular members 1 are expandable in the radial direction thereof. The stent is flexible and excellent in trackability to lumens, thus making it possible to allow the stent to pass through the three-dimensionally meandering lumens. The stent is substantially free from shortening and makes it possible to provide the stent with a lateral hole.
