  • Magnetically-levitated blood pump with optimization method enabling miniaturization
    Patent number: 10835652
    Abstract: A magnetically-levitated blood pump with an optimization method that enables miniaturization and supercritical operation. The blood pump includes an optimized annular blood gap that increases blood flow and also provides a reduction in bearing stiffness among the permanent magnet bearings. Sensors are configured and placed optimally to provide space savings for the motor and magnet sections of the blood pump. Rotor mass is increased by providing permanent magnet placement deep within the rotor enabled by a draw rod configuration.
    Type: Grant
    Filed: March 9, 2016
    Date of Patent: November 17, 2020
    Assignee: Worldheart Corporation
    Inventors: Michael R. Ricci, James F. Antaki, Josiah E. Verkaik, David B. Paden, Shaun T. Snyder, Bradley E. Paden, Jingchun Wu
