What Should Be Noted In The Fatigue Test And Study Of Intravascular Stent?

The fatigue test and study of the intravascular stent should evaluate the ability of the stent to maintain long-term structural integrity under the worst simulated physiological load conditions, and should evaluate the stent durability under all relevant fatigue load modes of the stent, which should be determined based on the intended clinical use (e.g., implantation site) and conditions (e.g., expansion ratio and stent overlap).
