  • Magnetically actuated positive displacement pump
    Patent number: 5302929
    Abstract: A positive displacement pump is provided which is especially suited to be used as a left ventricle assist device (LVAD). The pump is electromagnetically actuated. An electromagnet produces a pulse which repels a magnet mounted in a diaphragm which forms one wall of a pumping chamber. The pumping chamber thereby constricts and fluid is expelled. The electromagnet has a reverse taper core and core cup magnet which produce a bipolar field effect upon a diaphragm magnet to cause the return of the diaphragm to its starting position, without the application of external power.
    Type: Grant
    Filed: January 28, 1991
    Date of Patent: April 12, 1994
    Assignee: University of South Florida
