<p><P>PROBLEM TO BE SOLVED: To provide a stent which follows deformation in a contraction direction of a lumen in-vivo, such as pulsation, and deforms, blocks excessive diameter reduction of the lumen in-vivo, and maintains excellent expanded state of the lumen in-vivo after the stent is indwelling. <P>SOLUTION: In the stent 1, a plurality of ring bodies 2 provided with bending parts 4 and 5 for deforming when operating placement in-vivo and a linear part 7 which connects the bending parts and does not substantially deform when the placement in-vivo is operated are arranged and joined to one another. The linear part 7 is provided with a slidable part 6 provided in the middle of the linear part. The slidable part is provided with a proximal movement distance restriction function for permitting movements of linear parts 7a and 7b divided by the slidable part in the proximal direction, operating when the linear parts 7a and 7b divided by the slidable part 6 move in the proximal direction for a prescribed distance, and preventing further proximity. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
