Abstract

Our previous work proposed a Hemocompatibility assessment platform (HAP) to quantify blood trauma from individual left ventricular assist devices (LVAD) components. We used magnetic levitation bearings to minimize mechanical wear and hemolysis caused by the platform. The magnetic levitation bearings consisted of passive radial bearings and active axial bearings. We used a computational fluid dynamic analysis of the axial bearing design and observed fluid stagnation. We modified our design to increase fluid flow around the axial bearing and created a computational electromagnetic field model of the new design to characterize the forces produced by the bearing. We manufactured the axial bearing and experimental measurements of the axial forces were in good agreement with the simulation.
