esults were submitted to FDA per the methods described in ASTM F2077. Briefly,in each of these tests, devices are fixtured into a load frame and a static or dynamicaxial compression load, compression-shear load, or torque is applied. Static tests arerun until device failure, device-fixture interface failure, or test machine limits arereached. Dynamic tests are run until device failure occurs or the device reaches 5million cycles without failure
