Abbott Improves Medical Implantable Devices with Multiphysics Simulation
Freddy Hansen, Abbott, CA, USA
At Abbott, Freddy Hansen uses multiphysics simulation to model left ventricular assist devices (LVADs) to improve the outlook and quality of life for patients with heart failure. Numerical simulations spanning fluid dynamics, power supply, and thermal management allow him to characterize this complex device before experimental studies.
Development efforts at Abbott are centered on improving biocompatibility, hemocompatibility, and immunocompatibility to avoid an adverse response from the body. Hansen used the rotating machinery modeling technology available in the COMSOL Multiphysics® software to model a magnetically levitated rotor and turbulent blood flow. He also used the software to perform preliminary investigations into transferring power wirelessly to the device as well as evaluate the structural integrity of the external controller of the LVAD.
