An interface device between external equipment and at least a venous tube for transferring fluid to a patient, the interface device having at least a first port adapted to be connected to an outlet port of the external equipment; and a venous port carried by a stator of the interface device in order to inject the fluid into the venous tube. The interface device includes a third port, the first port and the third port being carried by a movable assembly that is movable relative to the stator, the interface device being arranged to pass from any one of its configurations to another one of its configurations by the movable assembly moving relative to the stator.

A dialysis system may include a blood circuit, a cassette, a subsystem having a processor, a sensor, and a blood pumping mechanism, a housing in which the subsystem is arranged, a movable support arranged in the housing and configured to hold the sensor and/or the blood pumping mechanism of the subsystem, a cassette holder configured to removably receive the cassette, and a loading system. The loading system may be configured to move the movable support, e.g. by an axial movement, to a first position and to a second position relatively to the housing while the cassette holder is fixedly arranged in the housing. The loading system may have an electric motor controlled by the processor, a drive assembly coupled to the electric motor, and a guiding assembly configured to cooperate with the drive assembly.

The present invention relates to a portable lung assist device. In one embodiment, the portable lung assist device comprises an integrated oxygenator, blood pump, and cannula. In one embodiment, the portable lung assist device of the present invention does not require an oxygen tank, but instead can provide oxygen to a subject's blood from ambient air. In one embodiment, at least a portion of the portable lung assist device, for example the cannula can be implantable. In one embodiment, the cannula of the device of the present invention can be inserted in to the subject's pulmonary artery. A method for providing portable lung assistance is also described.

A disposable fluid pump is provided with a housing including first and second faces, with a sidewall extending between the first and second faces. The housing defines a chamber, with an inlet and an outlet in fluid communication with the chamber. An impeller is rotatably mounted within the chamber and includes a plurality of flexible vanes. Such a pump may be incorporated into a disposable fluid flow circuit that is adapted to be mounted on a durable hardware for processing a fluid. In such a fluid flow circuit, the fluid pump may be integrated into a cassette of the circuit or, alternatively, the inlet and outlet of the fluid pump may be directly connected to fluid flow conduits of the circuit.

A dual lumen drainage cannula configured for use in a veno-arterial extracorporeal membrane oxygenation (VA ECMO) system includes a first drainage tube having a proximal end, a distal end, and at least one aperture defined proximate its distal end and in fluid communication with the lumen of the first drainage tube, and a second drainage tube having a proximal end, a distal end, and at least one aperture defined proximate its distal end and in fluid communication with the lumen of the second drainage tube. The dual lumen drainage cannula further includes a flow restrictor disposed within the lumen of at least one of the first and second drainage tubes, configured to adjust the flow distribution of blood flow through the lumens of the first and second drainage tubes.

The invention relates to a blood treatment device for carrying out an extracorporeal blood treatment in which blood is guided in a blood guidance device having a main blood line and at least one secondary line, the latter being fluidically connected to the main blood line and the main blood line having a dialyzer and, downstream from the dialyzer, a blood treatment element, wherein the blood treatment device has a control device; and a pump configuration, which is equipped for generating blood flows in the main blood line and also in the at least one secondary line, wherein the control device is designed to operate the pump configuration in such a way that a first blood flow rate in the dialyzer is decoupled from a second blood flow rate in the blood treatment element. Furthermore, the invention relates to a blood guidance device for cooperation with the blood treatment device as well as for a blood treatment system.

An extracorporeal blood treatment apparatus is provided comprising a filtration unit (2) connected to a blood circuit (17) and to a dialysate circuit (32), a preparation device (9) for preparing and regulating the composition of the dialysis fluid; a control unit (12) is configured for receiving a conductivity or sodium concentration set point for the dialysis fluid and for calculating a mass transport of a substance at an instant t of a treatment session based on said set value of the parameter for the dialysis fluid in the dialysis supply line (8).

The invention pertains to a medical device: an ECMO (extracorporeal membrane oxygenation) catheter which can be used during right heart and lung failure. It pertains to a dual lumen catheter with a single port of entry which when in place bypasses the right heart and lungs while completing the veno-arterial circuit.

A pump and valve arrangement (201), a dialysis system (10) comprising the pump and valve arrangement 201 and a method of operating a pump and valve arrangement (201). The pump and valve arrangement (201) has a dialyser having a semi-permeable membrane. The pump and valve arrangement (201) delivers dialysis fluid to and from the dialyser (12). The pump and valve arrangement (201) has a control system (450) configured to shuttle dialysis fluid between an inlet pump assembly and the dialyser (12) one or more times so as to agitate the surface of the semi-permeable membrane of the dialyser (12).
