Abstract: The present disclosure relates to control units for an extracorporeal circulatory support as well as systems comprising such a control unit and corresponding methods. Accordingly, a control unit for an extracorporeal circulatory support is suggested, which is configured to receive a measurement of an ECG signal of a supported patient over a predefined period of time, wherein the ECG signal comprises multiple data points for each time point within a cardiac cycle. The control unit comprises an evaluation unit, which is configured to evaluate the data points for at least one time point spatially and/or temporally and to determine at least one amplitude change within the cardiac cycle from the evaluated data points. The control unit is further configured to output a control signal for an extracorporeal circulatory support at a predefined time point after the at least one amplitude change.

Abstract: The present disclosure pertains to control units for non-occlusive blood pumps of an extracorporeal circulatory support as well as systems comprising such a control unit and corresponding methods. Accordingly, a control unit for a non-occlusive blood pump of an extracorporeal circulatory support is configured to receive a flow value of the extracorporeal circulatory support, to receive a measurement of an arterial pressure and an ECG signal of a supported patient over a predetermined period of time, to determine a mean arterial pressure of the extracorporeal circulatory support or of the supported patient from the measurement of the arterial pressure and an energy equivalent pressure from the flow value and the arterial pressure.

Abstract: The invention relates to a cannula comprising a tip and an outlet, the cannula having a reduction in the internal diameter, which reduction is designed as a conically tapering tip the end of which has a length that is shorter than the internal diameter of the adjoining portion of the cannula.

Abstract: An extracorporeal cardiac assistance system, comprising a pump being configured to create a fluid flow from a suction line to a pressure line of the system; further comprising a control device configured to control the pump and/or an adjustable flow limiter to provide an adjustable flow rate and/or a pressure, wherein the control device is configured to execute a support mode with a plurality of consecutive support flow rate pulses and/or support pressure pulses interposed on the fluid flow and to execute a weaning mode with a plurality of such pulses, wherein an amount of energy provided to the fluid flow with each pulse is lower in the weaning mode than in the support mode.

Abstract: An assembly for an extracorporeal life support system with a suction line that features a venous cannula and a pressure line that features an arterial cannula furthermore includes a pump that is arranged between the suction line and the pressure line. This assembly has a discharge line with a discharge cannula, wherein the discharge cannula is longer than the arterial cannula, and wherein the discharge line is connected to the suction line or the pressure line.

Abstract: In a system for extracorporeal membrane oxygenation including a blood pump and an oxygenator, the oxygenator includes fibrous mats stacked in a housing and arranged parallel to one another, and the blood pump includes a control unit that provides for a continuous variation of the volume of flow over time.
