Crushing Test For Stents Instron

Apr 26, 2021

In crush fatigue testing of vena cava filters, a custom compression waveform is applied in displacement control at approximately 20 Hz test frequency to mimic normal respiration and excursions to routine respiratory motions that arise from exertion. Vena cava stent crush resistance is assessed by compression between flat plates as

    Abstract Aims: Although provisional stenting with a single drug-eluting stent has proven clinical efficacy in the treatment of bifurcation stenosis, some patients may require two stents. We propose a novel technique, called “nano-crush”, which is easy to perform and can be used in all bifurcation angles.
