<p><P>PROBLEM TO BE SOLVED: To provide a flexible stent, gentle to lumens, etc. with excellent follow-up property to the lumens, etc., capable of easily forming a tunnel and evenly inflating without being shortened substantially. <P>SOLUTION: The stent comprises a plurality of annular members 1 inflatable in the radial direction, disposed in the longitudinal direction, and one or a plurality of connection elements 2 connecting adjacent annular members 1 and 1 in the longitudinal direction. The annular member 1 is continued in the circumferential direction with a plurality of loop-shaped elements 11, facing in the same direction with free ends 111 and 112 at both ends, connected by connection elements 12. The loop-shaped elements 11 are arranged in the vertical direction so that a straight line passing the free ends 111 and 112 orthogonally crosses the longitudinal axis. Adjacent loop-shaped elements 11 and 11 are connected by the nearest free ends 111 and 112, and the adjacent annular members 1 and 1 are connected by parts of the nearest connection elements 12 and 12. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
