Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that may include a magnetic drive system of a blood pump. The magnetic drive system may include a drive shaft coupled to an impeller, a driven magnet assembly coupled to at least one of the drive shaft and the impeller, and a driving coil assembly configured to drive the driven magnet assembly.

Abstract: A bearing assembly is configured to retain an end of an impeller of a blood pump and includes a thrust plate having a distal-facing surface and an impeller bearing surface configured to be disposed adjacent the distal-facing surface such that a gap is defined between the distal-facing surface of the thrust plate and the impeller bearing surface. The impeller bearing surface includes at least one washout blade disposed thereon and configured to facilitate blood flow through the gap.

Abstract: An axial flux motor includes a housing; a drive shaft disposed within the housing; at least one rotor; and at least one stator. The at least one rotor includes a diametrically-magnetized single pole pair magnetic ring having a rotor aperture defined through the center of the magnetic ring, where the drive shaft extends through the rotor aperture and where the at least one rotor is fixed to the drive shaft. The at least one stator includes a number of conductive windings and a stator aperture, where the drive shaft extends through the stator aperture and where the drive shaft is rotatable within the aperture. The at least one stator is configured to generate an axial magnetic field that causes the at least one rotor to rotate, thereby rotating the drive shaft.

Abstract: Devices and methods for assisting blood flow are provided. The device includes a housing with an inlet and an outlet, and a fluid barrier separating the housing into a first section containing the inlet and outlet, and a second section. The device also includes an impeller shaft coupled to an impeller and a first magnet in the first section of the housing, and a drive shaft coupled to a second magnet in the second section of the housing. The first and second magnets are arranged such that rotation of the drive shaft rotates the second magnet causing rotation of the first magnet, which drives the impeller.
