Abstract: A control apparatus for an implantable heart pump is provided, which comprises an implantable first control unit, which is electrically connected to the heart pump in a main operating state for controlling operating parameters of the heart pump. The control apparatus also comprises an interface, which is electrically connected to the first control unit and is intended to wirelessly transcutaneously transmit data and/or to wirelessly transcutaneously transmit energy between the first control unit and a further control unit provided for extracorporeal use. The control apparatus also comprises an implantable second control unit, which is electrically connected to the heart pump in an auxiliary operating state for controlling operating parameters of the heart pump, and an implantable switch, which is electrically connected to the first control unit and the second control unit. The switch is set up to change over between the main operating state and the auxiliary operating state.

Abstract: A pump is provided for conveying body fluids, in particular blood, wherein the pump has a pump housing and a rotor mounted in the pump housing. The rotor comprises at least one sensor for detecting flow and/or movement parameters. Also provided is a method for operating the pump.

Abstract: The present application relates to an outlet graft for a blood pump as well as to a system comprising a blood pump and an outlet graft that is connected to an outlet of the blood pump. The outlet graft includes a first end opposite a second end such that a longitudinal axis is formed between the first and second ends. The second end is connectable to a blood vessel and a lumen with a closed cover. A first strip included in the cover extends parallel to the longitudinal axis and is made of a material that is of a higher contrast under x-rays than the cover.

Abstract: Methods for operating a pump are provided, the pump comprising a rotor for conveying fluids, wherein the volume flow rate through the pump and the pressure difference across the pump is determined, wherein at least one first operating parameter and in particular a second operating parameter of a first group of operating parameters are detected and, depending on the value of the first and in particular also the value of a second operating parameter of the first group, the volume flow rate through the pump and the pressure difference across the pump is determined from detected values of the operating parameters, either from the first group of operating parameters, or values of another set of operating parameters, in particular at least one additional operating parameter, are taken into consideration in order to determine the volume flow rate and the pressure difference across the pump.

Abstract: A heart pump device may be provided with an implantable heart pump, which has at least one sensor, wherein at least one of the sensors is a sensor for a rotor of the heart pump, and with a control device, which is connected to the heart pump by means of a transcutaneous line, characterised by a signal processing device, which on the one hand is connected by means of the transcutaneous line to the control device, and which on the other hand is connected to at least one sensor of the heart pump and transmits signals of at least one sensor via the transcutaneous line to the control unit. The signal processing device may be for a pre-processing of the sensor data for more efficient transmission via the transcutaneous line.

Abstract: A heart pump and a method for operating a VAD (ventricular assist device) heart pump, in which method a time-dependent pressure of the blood to be delivered is measured directly by means of at least one pressure sensor arranged on the pump inlet and/or on the pump outlet. A temperature of the blood is additionally detected. By evaluating the measured pressure profiles and/or corresponding rates of change of the measured pressure, it is possible for delivery parameters of the pump, and physiological values of the heart assisted by the pump, to be determined in a convenient and reliable manner.
