| contents | This research aims to develop a method to reduce the time cost and complexity of balloon expandable stent simulations in cardiovascular stenting procedures for Peripheral Artery Disease. The study uses stereoscopic images to construct a cardiovascular stent and validate its mechanical response through Finite Element testing. A 3D model of the curved common femoral artery was constructed using Computed Tomography of a patient with Critical Limb Ischemia. The fatigue life cycles of the stent were estimated considering sinusoidal cyclic loading. The crimping process has a negligible influence on the mechanical response, with recoil and foreshortening percentages remaining static with increasing stent rings. The numerical results indicate the biomechanical influence of stent placement in a realistic vessel and compare it with literature. |
