Described is an endovascular cannula (L1b, L2b) for defining a border of a transport volume (TrV) for an in-vivo fluid transport, the cannula (L1b, L2b) comprising:—a lumen portion (LP) that extends between a proximal end of the cannula (L1b, L2b) and a distal end of the cannula (L1b, L2b), the lumen portion (LP) defining an inner lumen, and—an expandable arrangement that has a non-expanded state and an expanded state, wherein the expandable arrangement can be switched from the non-expanded state to the expanded state, wherein in the expanded state the expandable arrangement is adapted to define at least one border of the transport volume (TrV), and wherein the border is configured to separate the transport volume from a body fluid circuit (BC).

A holder for a curved duct portion of a tube pump. The holder includes a supply-side connector which includes a first cavity and a first plate connected together, the first cavity being adapted for receiving an end of the curved duct portion, and a discharge-side connector including a second cavity and a second plate connected together, the second cavity being adapted for receiving another end of the curved duct portion, where the connectors are movable the one with respect to the other between a storage configuration, in which the supply-side connector is positioned away to the discharge-side connector, and an operating configuration, in which the supply-side connector is close to the discharge-side connector and in which the first and second plate are engaged together substantially on a same plane.

A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

Described is a cannula (110, O1 to O3, I1 to I3) comprising: —a lumen portion (LP) that extends axially between a proximal part of the cannula (110, O1 to O3, I1 to I3) and at least one distal part of the cannula (110, O1 to O3, I1 to I3), and —an expandable arrangement (114) at the at least one distal part of the lumen portion, wherein the expandable arrangement (114) is adapted to have an expanded state and a non-expanded state, wherein in the expanded state a volume defined by the expandable arrangement (114) is greater than the volume defined by the expandable arrangement (114) in the non-expanded state.

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.

An extracorporeal circulation management device pumps blood in synchronization with heartbeats of a patient based on measurements of blood flow. Maximum and minimum blood flow measurement samples are compared with upper and lower threshold values to identify candidate timing for a systolic phase and diastolic phase of the heartbeat. During pulsatile pumping of the blood using the candidate timing, differences in the pulsatile flow measurements are determined. Based on the size of the difference, a final correction may be made to identification of the systolic and diastolic phases, and the corrected phase information is used to start and stop the motor unit.
