Abstract
The stent has an expansive force 0.05 N/mm or less per unit length when it has a diameter equal to the lower limit diameter of the target blood vessel and is measured under the following conditions. A radial force testing system manufactured by Blockwise Engineering LLC is used as a tester. The test conditions include a temperature of 37° C.±2° C. in the chamber of the tester; a stent diameter of 0.5 mm for start of test, and a rate of increase of diameter of 0.5 mm/s in the tester. The test method includes radially compressing the stent disposed in the chamber; recording an expansive force while gradually increasing the diameter of the chamber at the rate of increase of diameter; and dividing the expansive force by the effective length of the stent to calculate an expansive force per unit length.
