Dynatek’s new Fatigue-to-Fracture Tester highlighted in a paper presented at a recent ASTM International Symposium.
The American Society for Testing and Materials (ASTM) International subcommittee on Endovascular Test Methods developed the new standard ASTM F3211 Standard Guide for Fatigue-to-Fracture (FTF) Methodology for Cardiovascular Medical Devices.
Dr. Matthias Froscher of Cortronik presented a paper at ASTM’s Fourth Symposium on Fatigue and Fracture of Metallic Medical Materials and Devices in May 2018. This was the culmination of three years of research and instrument development by Dynatek and Cortronik. The paper “A New Approach for Fatigue-to-Fracture Testing of Coronary Stents” presented a test methodology taking the new ASTM standard into account, which can subject cardiovascular stents to hyperphysiological loading. In combination with FEA analysis, it can help to understand how stents fracture, e.g., to optimize device designs or evaluate the criticality of manufacturing process changes with regard to fatigue without the need to test to high numbers of cycles.
This testing was run on Dynatek’s patented FTF extreme conditions radial fatigue tester. The instrument utilizes Dynatek’s more than 30 years of experience designing and manufacturing medical device testing instruments. It provides extreme loading conditions to stents, so that they can be radially stressed to a much greater degree than previously possible.
This paper has been chosen for publication in STP 1616 on Fourth Symposium and Fatigue of Metallic Medical Materials and Devices to be available at the ASTM STP in the near future.

Dynatek Labs attended the 2017 TCT
Dynatek Labs attended the 2017 TCT (Transcatheter Cardiovascular Therapeutics) show in Denver, held Oct 30 through Nov 2 this year.
Drs. James Conti and Elaine Strope, owners of Dynatek; Kendra Conti, Global Sales Manager; and Chris Conti, Sr. Engineer, attended for Dynatek. The Acute Particulate Tester (APT), and the M6 Heart Valve Durability Tester, were showcased at this year’s exhibit.
Still haven’t seen Dynatek’s Acute Particulate Tester?
Make plans now to attend TCT 2017 and stop by our booth 4002, Oct. 30- Nov. 1, 2017.
Also featured will be our M6 accelerated durability tester for surgical and catheter-delivered heart valves as well as vascular occluders.
We look forward to seeing you there to discuss how Dynatek Labs can help with your vascular device durability and particulate testing needs!

Acute Particulate Testing in our lab is growing fast
No one tests faster than we do!
Test at accelerated speeds? Yes!
Test at physiological speeds? Yes!
Test at high temperatures and expanded pH levels? Yes!
Verify stent deflection using high speed photography? Yes!
ISO, ASTM and FDA regulations require the testing of stents and stent grafts for at least 380 million cycles. At physiological speeds of 72 beats per minute (1.2 Hz), it would take one month for 3.1 million cycles of testing, or literally 10 years to meet the regulatory requirements. To meet the regulatory requirements of 380 million cycles, regulatory agencies allow testing at accelerated speeds, leading to shorter test periods, and significantly lower testing costs.
Dynatek’s testers feature proprietary Hyper Drive motors that are capable of over 60 Hz or 3,600 rpm, far in excess of physiological conditions. Assuming the intravascular device can tolerate such speeds, 380 million cycles can be completed in 10 weeks!
Dynatek can assist you in developing a test protocol that will offer you the fastest possible speed for accelerated durability testing of stents, stent grafts and intravascular devices.
In addition to accelerated speeds, some customers have chosen to test at higher temperatures and expanded pH levels, as part of their test-to-failure protocols. Contact us to find out more about such testing protocols.
Verification of stent deflection using high speed photography is the most accurate way to measure deflection. Dynatek routinely performs accelerated durability testing of intravascular devices using high speed photography.
