Abstract
A stent including a plurality of loop stents connected by struts so that it bends uniformly as a whole. A stent A including a plurality of loop stents 2 connected by a plurality of struts 3, the loop stents 2 each formed of a stent main wire 1 folded into a zigzag shape and joined at its ends, wherein the bending strength of each strut 3 is larger than the bending strength of the stent main wire 1.
Claims6
A stent comprising a plurality of loop stents connected via a plurality of struts, the loop stents each formed of a stent main wire folded into a zigzag shape and joined at its ends,
- wherein the difference between the bending strength of the strut and the bending strength of the stent main wire is in a range of 20 g·cm to 200 g·cm when expressed in bending torque, the bending torque of the strut is in a range of 350 g·cm to 450 g·cm, and the bending torque of the stent main wire is in a range of 150 g·cm to 430 g·cm, so that the stent has a uniform bending strength.
