By combining a canned-motor with a magnetically levitated pump impeller, Switzerland's Levitronix GmbH has achieved a centrifugal pump with neither shaft seals nor impeller bearings. This has many advantages for the handling of a range of sterile, sh

Objective Mechanical support of a failing heart is typically performed with rotary blood pumps running at constant speed, which results in a limited control on cardiac workload and nonpulsatile hemodynamics. A potential solution to overcome these lim

The promise of expanded indications for left ventricular assist devices in the future for very long-term applications (10+ years) prompts sealed (i.e. fully implanted) systems and less-obtrusive and more reliable implanted components than their exter

In order to reduce the costs, radial active magnetic bearings have been proposed which consist of only three electromagnets. Unfortunately it is not possible to operate the three coils with a 3-phase power converter, since the sum of the coil current
