Animal data support maglev pump feasibility; leaves open clinical translation pending human trials.
Demonstrates the feasibility of achieving stable equilibrium in permanent maglev rotary artificial heart blood pumps using passive magnetic bearings.
Qian et al. (2005) studied this question. Permanent maglev rotary artificial heart blood pumps was evaluated on Stable equilibrium and levitation of the rotor. Two stable permanent maglev impeller blood pumps were developed, demonstrating that a rotating magnetic levitator can maintain stability using passive magnetic bearings and hydrodynamic forces.
