Abstract: A blood pump includes an impeller; a drive shaft coupled to the impeller and configured to rotate with the impeller; a motor configured to drive the impeller; and a bearing assembly disposed adjacent the motor and configured to receive an end of the drive shaft. The bearing assembly includes a bearing, where the end of the drive shaft is at least partially rounded, and the where the bearing includes a concave depression defined in a first side of the bearing, where the depression is configured to receive the end of the drive shaft. The bearing assembly may include a lubricant chamber configured to hold a lubricant.

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.

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.
