<P>PROBLEM TO BE SOLVED: To reliably fix a stent to a lumen. <P>SOLUTION: A stent system 1 includes: the stent 2 with holes; and at least one anchor 3 with arms 33. The stent 2 has a cylindrical shape obtained by rolling up a sheet, where the multiple holes 13 are punctured. Grip parts 33A at the distal ends of the arms 33 in the anchor 3 are inserted to the holes 13. The grip force X of the clip 3 and reactive force R to be shown by the holes of the stent 2 to be gripped has the relation of X>R. Thus, the clip 3 deforms the stent 2, easily grips the stent 2 and a tissue, and then, performs fixing. <P>COPYRIGHT: (C)2009,JPO&INPIT |
