  • Publication number: 20190167876
    Abstract: A centrifugal blood pump includes a housing that defines an inlet passage, a chamber, and an outlet passage. The pump includes an impeller rotatably positioned in the chamber to transfer blood from the inlet passage through the chamber and to the outlet passage and magnetic members embedded in the impeller such that the impeller and the magnetic members rotate together within the chamber. The pump includes a motor to control movement of the impeller in the chamber. The motor is adjacent the chamber and separated from the chamber by a partition member. The pump includes an inner annular magnetic member and an outer annular magnetic member embedded in a side of the housing opposite the partition member. A first net magnetic force between the inner annular magnetic member and the magnetic members exhibits greater attraction than a second net magnetic force between the outer annular member and the magnetic members.
