Abstract:
This paper presents the analysis of dependences between frame basic cell geometry parameters and function via finite element analysis. The simplified models of frame cell with varied strut width, thickness and quantity in a circle was researched to evaluate radial forces, maximum stress and strain, permanent residual strain and pinching load forces. The outcomes of this study might help in the development of new artificial heart valves and during the analysis of existing in-clinical TAVI prostheses.
