    Abstract

    The use of nitinol stents in the superficial femoral artery (SFA) is becoming commonplace. The SFA is a tortuous biomechanical environment that has challenged the durability of these devices. A thorough understanding of the biomechanical loading environment is necessary to design and evaluate new stents. This paper reports recent methods for use of bench testing as a tool to predict fatigue fracture of stents for complex multimode duty cycles.
