Finite element & CFD analysis of Cardiovascular Implants
FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization
Enteknograte can develop FE models of various cardiovascular implants for evaluating design, manufacturing, and delivery procedures, along with clinical performance. Modeling experience includes the following:
- Cardiovascular and peripheral stents—self-expanding and balloon expanding
- Vena cava filters
- Abdominal aortic aneurysm (AAA) grafts
- Artificial heart valves and devices—percutaneous (TAVI/TAVR) and surgically placed
- Ventricular reconstruction modeling
- User-defined material models for shape memory alloys
- Device life predictions using implant-vessel interaction models
- Bridge to implant or destination therapy LVADs
FDA submissions require a comprehensive audit trail which includes:
- Records of all simulation data
- Revision management and control
- Correlation with physical test results
- Proven repeatable methods
- Software version tracking
To ensure confidence in the simulation and reliability of the analysis results, medical device manufacturers must ensure that the CAE analyst is using the most current CAD geometry, specify the correct material properties, and apply the appropriate environmental loading conditions. They must also create the proper mesh type and size, record the version of the analysis software, and correlate results with physical test data. These criteria must be preserved and managed for FDA compliance purposes and for the benefit of enhanced enterprise productivity.
Enteknograte offers a Virtual Engineering approach with CFD and FEA tools such as Ansys Fluent, StarCCM+ for flows simulation and FEA based Codes such as ABAQUS, Ansys, Nastran and LS-Dyna, encompassing the accurate prediction of in-service loads, the performance evaluation, and the integrity assessment including the influence of manufacturing the components.
