Medtronic's Endovascular Therapies R&D team applied Abaqus finite element analysis and Isight probabilistic simulation to evaluate stent graft behavior under real-world conditions. The study incorporated manufacturing tolerances, patient-specific anatomy, and pulsatile fatigue loading to assess crimp strain, radial force, and long-term durability. Results were validated against bench testing and aligned with ISO and regulatory requirements for 10-year device performance.

Key takeaways

Abaqus FEA modeled Nitinol stent rings under crimp, deployment, and fatigue loading conditions

Isight automated DOE and probabilistic sampling across manufacturing tolerances and anatomical variability

Wire diameter and stent height identified as primary drivers of crimp strain and radial force

Simulation results matched physical bench testing for radial force and 10-year fatigue performance

Design cycle time reduced by an order of magnitude through virtual iteration before prototyping
