摘要：
A blood pump for pumping two blood streams, comprising: a housing (40, 50)； a stator (860) supported on the housing； and a rotor assembly comprising a rotor (880) supported in the housing for rotation relative to the stator (860) around an axis (852)； a first centrifugal pumping stage that includes a first impeller (34) functionally coupled to a first axial end of the rotor for rotation with the rotor around the shaft, and a second centrifugal pumping stage that includes a second impeller (36) functionally coupled to a second axial end of the rotor, opposite the first axial end, for rotation with the rotor around the axis, the stator (860) comprising a stator core (868)； a first lamination (862) wound around an axial part of the stator core and a second lamination (862) wound around a second axial part of the stator core (868), the first and second laminations (862) being spaced apart from each other. along the length of the stator core, and separated by a non-magnetic separator (864)； and the rotor (880) comprising a rotor core (882)； a first set of magnets (884) that extends around an axial part of the rotor core and a second set of magnets (884) that extends around a second axial part of the rotor core, the first and second assemblies being spaced of magnets (884) with each other along the length of the rotor (880), and separated by a non-magnetic separator (886).Una bomba de sangre para el bombeo de dos corrientes de sangre, que comprende: una carcasa (40, 50)； un estator (860) soportado en la carcasa； y un conjunto de rotor que comprende un rotor (880) soportado en la carcasa para su giro con relación al estator (860) alrededor de un eje (852)； una primera etapa de bombeo centrífugo que incluye un primer impulsor (34) funcionalmente acoplado a un primer extremo axial del rotor para su giro con el rotor alrededor del eje, y una segunda etapa de bombeo centrífugo que incluye un segundo impulsor (36) funcionalmente acoplado a un segundo extremo axial del rotor, op
