3.1.2 Technology Overview The CentriMag and PediVAS Blood Pumps are electronically driven, centrifugal Pumps based on bearingless motor technology. The centrifugal Pump allows pumping without mechanical bearings and seals. The basic bearingless centrifugal principle is shown in Figure 8. An impeller is floating and rotating in the magnetic fields of a stator without mechanical contact. A compact digital signal processor system with a servo amplifier allows precise regulation of the impeller location and speed.

Figure 8: Schematic depicting the basic principle of the bearingless centrifugal Pump and Motor External position sensors actively control the radial impeller position. Processor-controlled electronics regulate the magnetic fields so that the impeller is always centered. The electronics control precise regulation of the radial impeller position and the speed. Axial position and tilting of the impeller are passively stabilized (Figure 9). The non-contacting impeller is levitated by magnetic fields through the walls of the Blood Pump, and floats in the center of the Pump.

3.1.3 Mag Monitor The 2nd Generation CentriMag Primary Console is designed to be used with a Mag Monitor (Figure 4 and Figure 5). The Mag Monitor may be used with one or two 2nd Generation CentriMag Primary Consoles when a patient is supported in either a univentricular or biventricular support mode. The Mag Monitor permits the user to redundantly display data pertaining to System performance and status along with the Console display. When activated, the user is able to view System data directly on the Console display or the Mag Monitor. A second function of the Mag Monitor is to provide a redundant user interface to control Motor and Pump function. For detailed information regarding the Mag Monitor, refer to the appropriate section in this manual entitled “Mag Monitor Description and Connections” (Section 5.23). The Mag Monitor is designed for use only with the 2nd Generation CentriMag Primary Console. The Mag Monitor can be used when the System is stationary and powered on AC. In combination with the 2nd Generation CentriMag Primary Console Version 2 the Mag Monitor can be powered on battery as well. The runtime of the battery will shorten, if the Mag Monitor is used when the System is operated on battery. The Mag Monitor is not intended for use with the 1st Generation CentriMag Primary Console. In the biventricular mode, one Mag Monitor is connected to two 2nd Generation CentriMag Primary Consoles. The display on the Mag Monitor then displays data from both of the Consoles. The data from the Console used to support the left side of the heart is displayed in red, whereas the data from the Console used to support the right side of the heart is displayed in blue. Should the Mag Monitor be disconnected or fail, the 2nd Generation CentriMag Primary Console may be operated independently with the relevant operational data displayed on the Console display. When the Mag Monitor is active, control of Motor and Pump function may be accomplished using either the Mag Monitor or the Console. If a Mag Monitor is unavailable, the Pump and Motor can be controlled via the 2nd Generation CentriMag Primary Console. When operated in this manner, a number of features that can only be accessed via the Mag Monitor will not be available. These include; stopwatch function (Section 5.14), graphical displays of the pressure, as well as flow and alarm limits (Sections 5.11 through 5.13). In the absence of the Mag Monitor, the data log function is not accessible. In addition, data recording will be limited to the previous 16 hours of data. If a Mag Monitor is connected to the 2nd Generation CentriMag Primary Console it will be able to display the previous 16 hours of data collected by the System. Table 4 summarizes the differences between the System with and without the Mag Monitor.

CAUTION The Mag Monitor is intended for use only with the 2nd Generation CentriMag Primary Console. The Mag Monitor will not function with the 1ST Generation CentriMag Primary Console or any other Console.
WARNING The Mag Monitor can only be operated when it is connected to the 2nd Generation CentriMag Primary Console. The Console may be operational on AC or, in combination with the 2nd Generation CentriMag Primary Console Version 2, on battery. Operating the Mag Monitor while the Console runs on battery shortens the battery runtime. Refer to the individual RVAD or LVAD Console display for all operational data and audio/visual alarm messages.
WARNING Only USB-compatible Memory Sticks may be used to connect to the USB Port of the Mag Monitor. No other USB device may be used with the USB port (e.g. printer).
3.1.4 2nd Generation CentriMag Primary Console The 2nd Generation CentriMag Primary Console uses single phase AC power when used with the CentriMag Blood Pump. The 2nd Generation CentriMag System is capable of a flow rate of up to 10.0 LPM or maximum pressure head of 600 mmHg. Flows up to 1.7 LPM or a maximum pressure head of 540 mmHg may be generated with the PediVAS Blood Pump and circuit. In addition, each 2nd Generation CentriMag Primary Console contains a rechargeable internal battery that is capable of maintaining Console functionality in the event of a loss of AC power.
3.1.4.1 2nd Generation CentriMag Primary Console Front Panel The 2nd Generation CentriMag Primary Console (Figure 12 and Figure 13) is a microprocessor-based device. The microprocessors generate the primary Motor control signal, Mag Monitor System sensors, generate front display outputs and provide alarm functions.
