1. A dual pump artificial heart blood pump apparatus for use in a mammalian cardiovascular system comprising:

  • a first pump, having an input and an output connectable to said cardiovascular system;

    means for sensing pressure at the output of said first pump;

    means for sensing pressure at the input of said first pump;

    means for sensing flow rate through said first pump;

    a second pump, having an input and an output connectable to said cardiovascular system;

    means for sensing pressure at the output of said second pump;

    means for sensing pressure at the input of said second pump;

    means for sensing flow rate through said second pump; and

    means for controlling the speed of said first and second pumps based on the pressures and flow rates detected by said sensing means.
