    摘要： A blood pump has a hollow body in which an impeller with a spiral blading produces an axial propulsion of blood along the impeller, as well as an at least partly actively stabilized magnetic bearing device and a hydrodynamic bearing device for the impeller. The impeller may be set into a rotation about a rotation axis of the impeller with a motor stator located outside the hollow body. The hollow body has an inlet for the flow of blood into the hollow body in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow body in an outflow direction which is offset to the rotation axis of the impeller to produce a non-zero outflow angle (α) between the inflow direction and the outflow direction. A total artificial heart can be formed from two such blood pumps.

    摘要： The invention provides a device for the axial delivery of fluidal mediums, which outer diameter is not or only insignificantly larger than the diameter of the fluid carrying pipe, which reduces to a large extent a shearing and vortexing of the fluid. A device for the axial delivery of fluidal mediums, having a tubular hollow body arrangement, in which delivery area, an impeller (9) with a blading, which can be rotated, is arranged and also has a fluid directional means. A motor (2), at least one impeller (9) which can be rotated, and at least one motor mounting (14) are arranged in a tubular hollow body (1) of the hollow body arrangement. The impeller (9) is connected axially force-fittingly and/or form-fittingly to the motor (2).

    摘要： A rotational pump capable of running at a rotational speed (n) having a system for direct or indirect measurement of pressure difference or flow rate across the pump, wherein a control system is designed to calculate an index of pulsatility (PI) of the pressure difference or flow rate, estimating the gradient of PI with respect to the rotational speed (dPI/dn) and regulating the dPI/dn to a pre-defined set-point or regulating the pump in a way that the dPI/dn is minimal.
