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.
