Abstract: A cardiac pump includes a housing, a rotor extending along a rotational axis of the cardiac pump between first and second axial ends of the rotor, and a bearing assembly which supports the rotor within the cardiac pump housing for rotation about the rotational axis. The rotor includes a recess formed in an axial end face of the rotor. The housing includes a protruding portion extending axially into the recess. The bearing assembly includes: a first magnet assembly provided on a portion of the housing radially outward of the recess formed in the rotor, a second magnet assembly provided on a portion of the rotor radially outward of the protruding portion of the housing, and a third magnet assembly provided on the protruding portion of the housing. The first, second and third magnet assemblies at least partially overlap one another in a direction parallel with the rotational axis.

Abstract: A cardiac pump (1) comprising a cardiac pump housing (7), a cardiac pump rotor (8), and a bearing assembly (23), the bearing assembly (23) being configured to support the cardiac pump rotor (8) within the cardiac pump housing (7) for rotation about a rotational axis (A-A) of the rotor (8), wherein the cardiac pump rotor (8) comprises a tip profile having rotational variance about the rotational axis (A-A).

Abstract: A cardiac pump (1) includes a cardiac pump housing (7) having a blood inlet (9) that is offset from the longitudinal axis of the cardiac pump housing (7).
