Popis: Endovascular aneurysm repair (EVAR) is an established alternative to abdominal aortic aneurysms (AAA) surgery. It consists in excluding the aneurysm sac from the blood flow by inserting a stent-graft (SG). However, secondary interventions after EVAR are frequent, mainly due to SG flexibility issues, especially when the device is deployed in a tortuous AAA. To avoid these complications, a new generation of more flexible SGs has been developed [Weale, 2010]. However, design strategies remain empirical. The aim of this study was to compare the mechanical performances of two multi-material models of first (FG) and last generation (LG) SGs by simulating their deployment within a tortuous AAA.
