ASTM F 2079 (F-2079) quantifies the percentage by which the diameter of a stent decreases from its expanded diameter while still on the delivery balloon to its relaxed diameter after deflating the balloon. Practically, excessive expansion of the vessel into which the stent is to be implanted may cause tissue damage resulting in a poor immediate result or poor long-term outcome. Therefore measuring stent recoil is an essential part of evaluating the design. Related standards include: ASTM F2477.
