Abstract: A method of operating an implantable blood pump having a first stator, a second stator, and an impeller movably disposed there between. The method includes applying a first voltage waveform at first phase to the first stator to generate a magnetic field to rotate the impeller. A second voltage waveform is applied at a second phase shifted from the first phase to the second stator to rotate the impeller, the second voltage waveform is asymmetric to the first voltage waveform.

Abstract: A blood pump including a housing defining a fluid flow path, an upstream end, a downstream end, and an outlet at the downstream end. A rotor is disposed within the housing and within the fluid flow path, the rotor being rotatable independent of the housing in a first direction and configured to pump blood downstream toward the outlet. The housing defines an inflow cannula at the upstream end, the inflow cannula defining a proximal end proximate the rotor and an opposite distal end. The inflow cannula defines a major longitudinal axis and minor longitudinal axis, the distal end of inflow cannula defines a plurality of slots radially disposed about the distal end, the plurality of slots being at least one from the group consisting of sloped in the first direction with respect to the major longitudinal axis and angled in the first direction with respect to the minor longitudinal axis.
