Nov 21, 2019 · This indies that radial mechanical strength and elastic recoil on expansion should be an important parameter for a stent product, though they are closely related to the yield strength and elongation to failure [74, 75]. ASTM B939–15 and ASTM F2079–09 are the corresponding standards to specifically evaluate these two properties.

(c) Recoil (ASTM F207909): Minimal stent recoil is a desirable feature of a stent because it minimizes the maximum diameter to which a stent must be expanded to achieve its final relaxed diameter. Practically excessive expansion of the artery into which the stent is to be implanted may cause tissue damage resulting in a poor immediate or long ...
