摘要： PROBLEM TO BE SOLVED: To provide a rotary blood pump which can prevent problems of the related art requiring a seal member to prevent escape of blood from a pumping chamber as use of mechanical bearings necessitates protrusion of a shaft beyond the pumping chamber, which becomes a source of thrombosis and sometimes hemolysis as well as premature wear of an impeller.SOLUTION: A rotary blood pump includes one or more stators 32, 34 overlying exterior surfaces of a wall defining a pumping chamber. A rotatable impeller within the pumping chamber may have a hydrodynamic thrust bearing adapted to constrain a position of the impeller along an axis of rotation relative to the wall when the impeller is rotating about the axis of rotation. The impeller position may thus be constrained without requiring a constant magnetic pole magnetic force to be applied in the axial direction from a prescribed position of a housing.
摘要翻译：要解决的问题：提供一种旋转式血液泵，其可以防止需要密封构件的现有技术的问题，以防止使用机械轴承使血液从泵送室逸出，这需要将轴突出到泵送室之外，泵血栓形成的来源，有时溶血以及叶轮的过早磨损。旋转式血液泵包括一个或多个定子32,34，覆盖限定泵送室的壁的外表面。泵送室内的可旋转叶轮可以具有流体动力推力轴承，其适于当叶轮围绕旋转轴线旋转时，相对于壁沿着旋转轴线约束叶轮的位置。因此，可以限制叶轮位置，而不需要从壳体的规定位置沿轴向施加恒定的磁极磁力。

摘要： A ventricular assist device includes a pump such as an axial flow pump, an outflow cannula connected to the outlet of the pump, and an anchor element. The anchor element is physically connected to the pump, as by an elongate element. The pump is implanted within the left ventricle with the outflow cannula projecting through the aortic valve but desirably terminating short of the aortic arch. The anchor element is fixed to the wall of the heart near the apex of the heart so that the anchor element holds the pump and outflow cannula in position.
