The purpose of this test method is to quantify the stent diameter retraction rate from the expansion diameter of the stent on the balloon to the post-decompression diameter after the balloon is removed. This test method is suitable for stents made of materials whose diameter can be plastically deformed before and after deployment under the action of mechanical methods. This test method can be performed at room temperature, unless a material has special temperature requirements, the test temperature should be specified in the report. This standard does not cover all safety issues related to use. Users of this standard are responsible for determining its suitability by establishing appropriate safety and health evaluation mechanisms before use.
