As catheter-based heart valve replacement procedures become more common, medical device companies are investing in technologies that can improve valve performance and durability. Medtronic, a medical technology company specializing in cardiovascular care, is using SIMULIA Abaqus finite element analysis software to study how transcatheter heart valves respond during compression, catheter delivery and expansion inside the heart. The simulations help engineers analyze mechanical stress, deformation and interaction between the valve frame, tissue leaflets and sutures under complex loading conditions. The digital models are being used to support device design, durability studies and engineering verification during the development of catheter-delivered heart valve technologies.
