    Abstract: Various “contactless” bearing mechanisms including hydrodynamic and magnetic bearings are provided for a rotary pump as alternatives to mechanical contact bearings. In one embodiment, a pump apparatus includes a pump housing defining a pumping chamber. The housing has a spindle extending into the pumping chamber. A spindle magnet assembly includes first and second magnets disposed within the spindle. The first and second magnets are arranged proximate each other with their respective magnetic vectors opposing each other. The lack of mechanical contact bearings enables longer life pump operation and less damage to working fluids such as blood.

    Abstract: A heart assist device comprising a rotary pump housing having a cylindrical bore, a pumping chamber and a motor stator including an electrically conductive coil located within the housing and surrounding a portion of the cylindrical bore. A rotor has a cylindrical shaft, at least one impeller appended to one end of the shaft, and a plurality of magnets located within the shaft. The rotor shaft is positioned within the housing bore with the magnets opposite the motor stator, and the impeller is positioned within the pumping chamber. The housing bore is closely fitted to the outer surface of the shaft forming a hydrodynamic journal bearing, with the pumping chamber and journal bearing connected by a leak path of blood flow between the pumping chamber and the journal bearing. A backiron of the motor stator attracts the rotor magnets to resist longitudinal displacement of the rotor within the housing during operation. The relative orientation of positions of the inflow, outflow, and leakage flow paths may be varied within the pump, such as to accommodate different intended methods for implantation and/or use.

    Abstract: The catheter device comprises a motor located at the proximal end of the catheter device and a drive shaft, extending from the proximal end section to the distal end section of the catheter device, for driving a rotating element located at the distal end of the catheter device. The catheter device also comprises a hose-like catheter body which encompasses the drive shaft and extends from the proximal end section to the distal end section of the catheter device. At the proximal end of the catheter device, the drive shaft is connected to a motor by a clutch. The clutch is a magnetic clutch with a proximal and a distal magnet unit. The proximal magnet unit is connected to the motor and the distal magnet unit to the drive shaft. The distal magnet unit is mounted fluid-tight in a clutch housing. The proximal end of the catheter body makes a fluid-tight connection with the clutch housing.

    Abstract: The invention relates to an integrated centrifugal blood pump-oxygenator (1) comprising a housing (2) with a top (3) having a blood inlet (4), a blood outlet (5) and a gas inlet (6), and a bottom (7) having a rotational body (8) being rotatably arranged in a rotor-housing (9) of the bottom (7). The integrated centrifugal blood pump-oxygenator (1) further comprises an oxygenator membrane (10) provided in an interior (11) of the housing (2), wherein in the operation state oxygen (12) is transferred from the gas inlet (6) through the oxygenator membrane (10) to an gas outlet (13) and a blood (14) is brought in direct contact with the oxygenator membrane (10) by pumping the blood (14) by the rotational body (8) from the blood inlet (4) to the blood outlet (5). According to the invention, the rotational body (8) is magnetically journalled in a contact free manner with respect to the rotor-housing (9). The invention is also related to an extracorporeal life support system (1000) and a method of de-bubbling and priming a extracorporeal life support system (1000) in accordance with the present invention.

    Abstract: An intracardiac rotary pump (10) is provided with a pressure differential sensor (18) for supporting the pumping heart. The pressure differential sensor measures the pressure differential between aorta (AO) and left ventricle (LV). This pressure differential must correspond to certain desired values at different speed stages. If the pressure differential deviates to too large an extent, the deviation is recognized as a drift of the pressure sensor, and a correction value is determined in dependence on the drift, the subsequently measured pressure values being corrected with the aid of this correction value. In this manner it is possible to carry out a drift correction on the sensor with the pump arranged in the heart and even with the pump in operation.

    Abstract translation: 心内旋转泵（10）设置有用于支撑泵送心脏的压差传感器（18）。 压差传感器测量主动脉（AO）和左心室（LV）之间的压差。 该压力差必须对应于不同速度级的某些所需值。 如果压力差偏离到太大程度，则将偏差识别为压力传感器的漂移，并且根据漂移确定校正值，随后测量的压力值借助该校正值被校正。 以这种方式，可以在传感器上进行漂移校正，其中泵布置在心脏中，甚至泵在运行中。
