Abstract (en)
[origin: WO9934847A2] A sealless implantable rotary blood pump including a number of features which improve its performance over the prior art. Such features include a fully floating shaft on magnetic bearings to avoid thrombus formation, a split blood flow path allowing for improved motor efficiency, a brushless motor operating in the left ventricle independently from the pump impeller, an axial/radial flow impeller coaxially mounted with the motor and operating within a portion of the housing placed outside the heart and means for imparting pulsatility to the output of a rotary pump.
