Pulsatile radial fatigue tests are performed to radially load stents and graft specimens repetitively to evaluate the fatigue resistance of the device. MDT has performed many radial pulsatile fatigue tests and has developed a wide range of test configurations for different specimen geometries. Some of the tests we have performed are highlighted below.
In this test devices are placed in straight mock arteries mounted to a stent/graft tester and subjected to cyclical pressure pulses. The pulses create a dynamic radial strain in the mock artery which simulates the strains found in vivo. The test is designed to simulate the device radial fatigue due to expansion and contraction of the surrounding vessel.
In this test devices are placed in curved mock arteries mounted to a stent/graft tester and subjected to cyclical pressure pulses. The pulses create a dynamic radial strain in the mock artery which simulates the strains found in vivo. Typical indications for the devices tested would include peripheral, neuro and some coronary locations.
This test is designed to simulate the AAA device radial fatigue due to expansion and contraction of the surrounding Aortic and Iliac vessels and the Aortoiliac junction. The test is conducted under simulated physiological conditions with saline at 37°C.If you don't see the pulsatile fatigue test you are looking for chances are we have already performed the test but have not listed it here. Contact us with your testing requirements and we will provide an estimate for creating the pulsatile fatigue test you are looking for.
