A method is provided for producing a bearing arrangement for an implantable blood pump. A bearing arrangement and an implantable blood pump are also provided. In the method, a rotor may be provided having one or more drive magnets. The rotor has a conveying element. In addition, a stator having stator windings is provided. Furthermore, the rotor is arranged in a flow channel formed by an inside wall of the stator. A rotor rotation is then driven. While the rotor rotation is driven, a deflection of the rotor is determined. In addition, the deflection of the rotor may be corrected by applying, removing, magnetizing and/or demagnetizing magnetically active material on the stator and/or on the rotor in a non-rotationally symmetrical manner.

A blood pump with a rotor can be driven to rotate about an axis of rotation for conveying blood. A control is being configured to operate the rotor successively in time, or alternately several times, in a first conveying mode and at least in one second conveying mode. In order to avoid dead water areas in the region of the rotor and possible thrombus formation the direction of rotation of the rotor is reversed in the second conveying mode compared to operation in the first conveying mode.

A system, such as a blood pump system, is provided for securing a releasable connection between two elements, in particular between two cables or between two hollow bodies, said system comprising: a first connector and a second connector that is releasably connectable to the first connector, a securing sleeve which, when the first connector is connected to the second connector, is movable, by displacement of the securing sleeve relative to the first connector and relative to the second connector into a securing position in which the securing sleeve completely or at least partially receives the first connector and the second connector, and a latching device with at least one latching element, wherein the latching device is configured to produce a latching connection between the securing sleeve in the securing position and the first connector and/or the second connector connected to the first connector.

Medical functional units and methods are disclosed. A medical functional unit may comprise an electrical energy supply system which includes one or more rechargeable sodium-ion batteries, where the energy supply system and the rechargeable sodium-ion batteries comprise fewer than six, fewer than five, fewer than four, fewer than three, or fewer than two of the following six protective devices: (a) charging current protection, (b) load current protection, (c) low-voltage protection, (d) overcharge protection, (e) high temperature protection, and (f) temperature-dependent load current limitation. A method for sterilizing a functional unit may comprise rechargeable sodium-ion batteries.

A pump system is provided for pumping a fluid and a method is provided for operating the pump system. The pump system comprises a first diaphragm fluid pump, a first inlet cannula connected to the first diaphragm fluid pump for supplying a fluid to the first diaphragm fluid pump, a first outlet cannula connected to the first diaphragm fluid pump for discharging the fluid out of the first diaphragm fluid pump, and a first service pump, which is connected via a first pressure line to the first diaphragm fluid pump and is confirmed to drive the first diaphragm fluid pump via the first pressure line. The pump system further comprises a first inlet flow sensor for detecting a first inlet flow of the fluid in the first inlet cannula and/or a first outlet flow sensor for detecting a first outlet flow of the fluid in the first outlet cannula.

A safety mechanism for locking and releasing an accumulator unit of a VAD system with a control unit of a VAD system may be provided. Safety mechanisms may comprise a latching hook having a latching lug, a latching opening, and an actuating element, and may have a rest position, a pre-release position, and a release position as described herein. An actuating element may be configured such that actuation of the actuating element moves the latching hook and/or the latching opening from a pre-release position into a release position.

A fluid pump is provided for delivering a fluid, particularly blood, comprising: a housing with a fluid inlet and a fluid outlet and a rotor, which is mounted in the housing such that it can rotate about an axis of rotation in order to deliver the fluid from the fluid inlet to the fluid outlet, the rotor being mounted in the housing by means of a mechanical bearing. A flow cross-section between the rotor and the housing has a local or partial flow cross-section minimum in the direction of the axis of rotation in the region of the mechanical bearing.

Control units for blood pumps and methods to operate such control units are disclosed. A control unit may comprise a blood pump port and include an energy storage unit and an energy supply unit. A charging interface may be configured to receive electrical energy from an external electrical energy source and a charge management unit may be configured to receive a charge level of the energy storage unit and to supply the energy storage unit with electrical charging power received via the charging interface to charge the energy storage unit. A control unit comprises at least one operating parameter detection unit configured to determine an operating parameter of the control unit. A charge management unit is designed to set a value of a charging voltage, a value of a charging current, an upper charging limit, and/or an alarm signal threshold value using at least one of the operating parameters.

A blood pump may be provided for supporting heart function. A method may be provided for producing a pump housing of the blood pump. The provided blood pump comprises an implantable pump housing. The blood pump additionally comprises a fiber optic sensor comprising an optical fiber. The optical fiber is at least partially accommodated in a housing part of the pump housing.

An assembly comprising a component for a blood pump and a plug, wherein the component has a plug socket for detachably receiving the plug in order to establish an electrical connection to the blood pump. The plug may have a coupling portion arranged at a tip of the plug and insertable into the plug socket. The plug socket may comprise an electrically insulating socket housing having a housing inlet and a housing interior adjoining the housing inlet for receiving the coupling portion, wherein an alignment from the housing inlet into the housing interior defines an insertion direction of the plug. The plug socket may comprise a locking unit configured to detachably lock the plug inserted into the plug socket and configured to lock the plug in the socket housing without restricting rotation of the plug in the socket housing about the insertion direction.
