ABSTRACT:
A centrifugal blood pump and method of pumping blood to reduce the pressure in either the right or left ventricle in synchronism with the ventricular contractions of a failing heart. The pump is implanted in a parallel relationship with the ventricle to be assisted and is run at a constant speed. When the pressure in the ventricle reaches a predetermined value, blood will automatically start to flow through the pump thereby reducing the maximum allowable pressure in the ventricle being assisted.
