ASTM F2942 – Standard guide for in vitro axial, bending, and torsional durability testing of vascular stents

This standard includes three separate cyclic deformation durability guides related to vascular stents. It applies to balloon-expandable and self-expanding stents fabricated from metals and metal alloys. Endovascular grafts (“stent grafts”) and other products used to treat aneurismal disease, peripheral vessel trauma or to provide vascular access are also included. This standard provides an in vitro modeling of stent durability from non-radial arterial motions.

Test methods included are:

• Axial durability of vascular stents
• Bending durability of vascular stents: column buckling guide
• Bending durability of vascular stents: bending on a mandrel
• Bending durability of vascular stents: bend in an arc without a mandrel
• Torsional durability of vascular stents
