  • Centrifugal blood pump apparatus
    Patent number: 6443983
    Abstract: A centrifugal impeller-type pump for transporting blood has a new and improved design in the impeller, to allow for the elimination of stagnant flow areas, and a geometrical design that minimizes damage to the blood components. A system for controlling and stabilizing the speed of centrifugal-type pumps used in a human cardiovascular system is also provided. Further provided are methods of corrosion protection and enhancing thromboresistance, rejection of waste heat, and methods to connect the artificial heart to the cardiovascular system as a Left Ventricle Assist Device (LVAD) and as a Total Artificial Heart (TAH).
    Type: Grant
    Filed: December 17, 1999
    Date of Patent: September 3, 2002
    Inventors: Lorant Nagyszalanczy, Kurt H. Wieland, Dan Lemay, Norman E. Spicer, Jack Sternlieb
