The cost to bring a medical device from concept to market, when exploring a large number of design parameters, continues to increase and often requires animal and clinical trials. Major advances in computational tools and visualization have paved the way to simulation-based design of a wide array of medical devices. As models for structural and fluid mechanics simulations improve, the next step is to couple fluid and structural simulations for a solution that can better capture the overall dynamics of a device. This talk reports on current progress and lessons learned by our interdisciplinary team, which is creating an "as accurate as possible" fluid-structure interaction (FSI) model for simulating the dynamics of the right atrium (RA) of a real heart, with and without an implanted pacemaker wire. This model-development project fits into a larger program of research on virtual prototyping of medical devices by coupling supercomputer-based simulation with interactive visual design tools and big data. This presentation will also present our ultimate goal which is to develop a computational model that fits appropriately into a simulation-based design workflow such that, with a robust computational model in hand, different parameters (e.g., lead wire geometry, mechanical properties) and scenarios (e.g., patient-specific anatomy) can be explored and visualized using innovative interactive design tools. Preliminary results will be presented.
