Vascular Stent Testing Standard is being developed by ASTM.

Press Release Summary:

Oct 04, 2013 - Medical device manufacturers and academics working with vascular stent testing are welcome to join in developing proposed new ASTM International standard ASTM WK23330, Guide for in Vitro Axial, Bending and Torsional Durability Testing of Vascular Stents. Testing described therein will be used to support acceptable fatigue resistance of stents for clinical use in vasculature as well as to enable regulatory bodies to better assess adequacy of testing conducted.

Proposed Vascular Stent Standard Being Developed by ASTM International Surgical Materials Committee

Press release date: Sep 26, 2013

W. CONSHOHOCKEN, Pa.—All interested parties are welcome to join in the development of a proposed new ASTM International standard that will provide guidance on how to conduct axial, bending and torsional fatigue testing of stents.

The proposed new standard, ASTM WK23330, Guide for in Vitro Axial, Bending and Torsional Durability Testing of Vascular Stents, is being developed by Subcommittee F04.30 on Cardiovascular Standards, part of ASTM International Committee F04 on Medical and Surgical Materials and Devices.

“Non-radial arterial motions of stents from musculoskeletal activities, such as walking and breathing, and cardiac motion, have been identified to be important in many arteries, for example, SFA, renal, carotid and coronary, however there are no standards on how to conduct such testing,” says Brian Choules, director, nonclinical testing, MED Institute Inc., and chair of F04.30.

According to Choules, the testing described in the ASTM WK23330 will be used to support the acceptable fatigue resistance of stents for clinical use in the vasculature. The standard will also enable regulatory bodies to make better assessment of the adequacy of the testing conducted.

Once approved, the proposed standard will be used by medical device manufacturers, testing laboratories and various regulatory bodies.

Subcommittee F04.30 is seeking participation from medical device manufacturers and academics working with vascular stent testing. The subcommittee’s standards developing activities include plans to work on guides for radial loading, sample size, fatigue to fracture and absorbable stents.

ASTM International welcomes participation in the development of its standards. For more information on becoming an ASTM member, visit www.astm.org/JOIN.

ASTM International is one of the largest international standards development and delivery systems in the world. ASTM International meets the World Trade Organization (WTO) principles for the development of international standards: coherence, consensus, development dimension, effectiveness, impartiality, openness, relevance and transparency. ASTM standards are accepted and used in research and development, product testing, quality systems and commercial transactions.
