A system for the extracorporeal elimination of carbon monoxide, includes at least one pump and a gas exchange chamber, wherein the at least one pump can be connected to the blood circulatory system of a person by way of a first tube section connectable to a cannula and is connected to a gas exchange chamber via a second tube section, wherein the system is configured to transfer blood, via the first tube section, from the blood circulatory system of the person by way of at least one pump into the gas exchange chamber, and to return the blood from the gas exchange chamber to the blood circulatory system of the person via the same first tube section.

System for the extracorporeal elimination of carbon monoxide

The invention relates to a rotary piston pump, in particular for pumping blood, comprising a piston rotor () which has particularly two or three faces when seen in cross-section, which is mounted in a piston chamber () and eccentrically rotates, the piston rotor () having in its interior a plurality of magnetically interacting elements (), in particular permanent magnets and/or coils, and being driven by the magnetic interaction of these elements () with at least one moving magnetic field.

Rotary-piston pump

An oxygenator module for gas exchange between blood and a gas in an extracorporeal lung support system, with several layers of semipermeable, gas-perfusable hollow fibers, wherein the hollow fibers of one of the layers are oriented at an angle of rotation about a central longitudinal axis of the oxygenator module with respect to the hollow fibers of another one of the layers, and with a potting which extends along the central longitudinal axis and in which the hollow fibers are fixed, wherein the potting defines a cavity that extends along the central longitudinal axis and in which the hollow fibers are arranged and which is blood-perfusable in the direction of the central longitudinal axis, wherein the potting has an essentially circular inner sheath surface that limits the cavity radially outward; as well as a method for producing the oxygenator module.

Oxygenator module, oxygenator and production method

The invention relates to a method of controlling the speed of a ventricular assist device, in particular the rotational speed of a rotary blood pump, wherein at least temporarily the speed of the device is modulated around a mean speed and a response of the native heart to this modulation is measured to determine the ventricular function/contractile state of the heart, in particular to determine whether the aortic valve opens and closes at the instant mean speed, and the mean speed is set, in particular a new mean speed is set in dependence of the measured response. The invention furthermore relates to a device performing the method.

Ventricular assist device and method of controlling same

The invention relates to an impeller () of a centrifugal pump apparatus, in particular of a blood pump apparatus, comprising a discoidal body () rotatable around an axis () of rotation, the body () comprising an upper surface (), a lower surface (), a central channel () extending in the direction of the axis () of rotation between the upper and lower surface () for guiding fluid, in particular blood through the body () in axial direction when the body () is rotated in a pump chamber of a pump and several blades () supported by the upper surface () for pumping fluid, in particular blood, when the body () is rotated in a pump chamber of a pump, several spiral grooves () in the lower surface (), each groove () having a bottom () and two sidewalls () and being open in an axial direction, merging into a circumferential surface () of the body () and extending from this circumferential surface () to the central channel () at least for providing a pumping action of fluid, in particular blood, from the circumferential surface () to the central channel () when the body () is rotated within a pump chamber of a pump, permanent magnets () integrated in the body () for driving the impeller by means of a magnetic field wherein each groove () is also merging into the central channel (), one of the sidewalls () of each groove () being higher above the bottom () than the other sidewall (), in particular the leading sidewall () with respect to the regular direction (R) of rotation being higher than the trailing sidewall (), a respective surface area () being disposed between each two neighboring grooves () and connecting the leading sidewall and the trailing sidewall of neighboring grooves, in particular thus forming a tilted pad area between each pair of neighboring grooves. The invention furthermore relates to a centrifugal blood pump apparatus comprising such an impeller.

The invention relates to a blood cannula for discharging blood into a vessel, in particular aortic cannula for discharging blood into an aortic arch during heart-bypass surgery, comprising a tubular body (), the tubular body having a straight part at the proximal end () and a bent part at the distal end () leading into an outlet opening (), wherein the distal end (), in particular the bent part has an increasing cross section in the direction of blood flow (B).

Blood cannula

An axial-flow blood pump has a rotatable impeller assembly rotatable about an axis and itself having a radially projecting blade and permanent magnets, A stationary stator assembly has stator windings interacting with the permanent magnets and a bearing system supporting the rotatable impeller assembly for rotation about the axis relative to the stator assembly. A stent implantable into a blood vessel is connected to ends of supports for coaxially mounting the stator assembly carrying the impeller assembly in the stent.

Axial-flow blood pump

A cardiac function variation evaluation apparatus includes: a continuous flow type auxiliary artificial heartconnected to a ventricle (A); a pressure sensorfor detecting ventricle (A) internal pressure; and means (a personal computer) for evaluating contractile variation of the ventricle, to which the auxiliary artificial heartis connected, based on internal area APMp of a closed-loop of a relationship between the ventricle internal pressure detected by the pressure sensorand a consumption power of the auxiliary artificial heart. Thus, the contractile variation of the ventricle, to which an auxiliary artificial heart is connected, can be continuously evaluated not by use of an ultrasonic echo apparatus or a conductance catheter but by use of a non-invasive method.

Cardiac function change evaluating device

The invention relates to an electrical linear drive, in particular for a pump system of an artificial heart, with a movable part and a stationary part, wherein the stationary part is formed by a permanent magnet arrangement and the movable part is formed by a coil arrangement, or vice versa, and wherein the coil arrangement and the permanent magnet arrangement can be moved to and fro relative to each other in an axial direction by means of current passed through the coil arrangement. The invention further relates to an electrical linear drive of this kind in which the permanent magnet arrangement is designed as a stack of frame-shaped, in particular ring-shaped magnets, which are magnetized alternately radially and axially in the axial direction, such that the magnetic field is strengthened on one side of the frame.
