Abstract
An artificial heart for use in a human recipient includes a housing within which a quartet of turbine pump segments are operative. The quartet of turbine pump segments is configured to provide a pair of redundant input and output turbine pump segment pairs each input and output pair being coupled by a curved passage providing a redundancy which, in turn, enhances the safety factor provided by the artificial heart. Each turbine pump segment includes an impeller forwarded for rotation and having a plurality of impeller blades together with a static deswirler positioned within the impeller output flow to reduce the swirling turbulence of the blood flow induced by the rotating impeller.
