ASTM F2477 In Vitro Pulsatile Endurance Test of Vascular Stents

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM F2477 testing. This standard covers the determination of the durability of a vascular stent by exposing it to physiologically relevant diametrical stress levels through hydrodynamic pulsatile loading.

ASTM F2477 In Vitro Pulsatile Endurance Test of Vascular Stents

This test is performed on a test specimen of a stent placed in a sham (simulated elastic) vessel. The typical duration of this test is the equivalent of 10 years of use (72 beats per minute), or at least 380 million cycles.

These test methods are applicable to balloon-expanding and self-expanding stents made of metals and metal alloys. It does not specifically address any properties inherent to coated stents, polymeric stents, or biodegradable stents, but this test method does not preclude application to these products.

These test methods do not include recommendations for endovascular grafts ("stent-grafts") or other canal products commonly used to treat aneurysm disease or peripheral vascular trauma or to provide vascular access, although some of the information contained herein may apply to these devices.

These test methods are applicable to determine stent failure due to typical cyclic blood vessel diametrical stretching. These test methods do not address other failure modes such as dynamic bending, torsion, elongation, crushing or wear.

These test methods do not address test conditions for curved mock cups. These test methods do not address test conditions for overlapping stents.

Values ​​stated in SI units should be accepted as standard. No other units of measurement are included in this standard.

This standard does not purport to address all safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
