The purpose of this test is to determine the load required that causes clinically relevant buckling or a deflection equivalent to a diameter reduction of at least 50%, and the load required to permanently deform or fully collapse the stent. The purpose of this test is to also determine whether the stent recovers its original geometry after testing.
