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: The present invention relates to a magnetic stimulation (MS) and preferably transcranial magnetic stimulation (TMS) coil arrangement designed for use as a placebo treatment. Accordingly, the purpose of the invention is to reduce or remove the effect of the magnetic field generated in use by a magnetic stimulation coil arrangement whilst the appearance presented remains as expected from a MS coil arrangement. The invention comprises a radially wound conductive element having a plurality of turns forming at least one winding. There is further provided at least one conductive magnetic field disrupting element at least partially positioned adjacent to the at least one winding for disrupting a magnetic field generated in operation by the at least one winding. The conductive magnetic field disruptive element accordingly attenuates the generated magnetic field beneath the coil arrangement.
