Design and finite element-based fatigue prediction of a new self-expandable percutaneous mitral valve stent
A novel nitinol design for percutaneous mitral valve replacement is presented. The design can address issues of valve migration and paravalvular leakage. Crimpability of the self-expandable stent was studied by the finite element method. Fatigue analysis has been simulated for the design under various cyclic loadings.
