Abstract
A heart pump including a housing forming a cavity including at least one inlet and at least one outlet, an impeller provided within the cavity, the impeller including vanes for urging fluid from the inlet to the outlet upon rotation of the impeller, a drive that rotates the impeller within the cavity, a magnetic bearing including at least one bearing coil that controls an axial position of the impeller within the cavity and a controller. The controller includes an electronic processing device that monitors changes in a bearing indicator in response to a perturbation in blood flow, the bearing indicator being at least partially indicative of operation of the magnetic bearing and controls the drive to thereby selectively change a rotational speed of the impeller at least partially in accordance with changes in the bearing indicator.
