  • Use gloves when setting up and operating the MAG
  • When transporting or handling the MAG, use caution and care to avoid product damage.
  • When used with products that require fluid cooling, set up the MAG so that it is not in proximity to the fluid cooling subsystem to protect the generator from any ingress of fluid.
  • To prevent patient burn at the neutral electrode site only use an adult Patient Return Electrode with Contact Quality Monitoring (CQM) or Return Electrode Monitoring (REM) Make sure there are no obstructions underneath or the rear of the MAG to provide sufficient air flow for cooling.
  • Only use as marked fuses to ensure the MAG is protected and functioning as intended.
  • To ensure correct operation the MAG should not be used adjacent or stacked with other equipment, except for intended stacking with Atri Cure’s equipment in accordance with the instructions. The MAG normal use configuration should be observed to verify normal operation.

CAUTION

  • The audible tone and indicator are important safety features. Do not obstruct the audible indicator. Ensure that the audible tone can be heard by personnel in the operating room prior to use. The audible tone alerts personnel when the Handpiece is active; refer to Table 5. Do not disable the audible tone.
  • The surface of the active electrode may remain hot enough to cause burns after the RF current is deactivated.
  • Inspect all products and packaging before use. If any breach in the packaging or damage to the product is found, the product should not be used.
  • To prevent device malfunction, do not install any other software on the MAG.
  • Standard care should be used to reduce the risk of tripping on the Footswitch cable.
  • To avoid interference place monitoring electrodes as far as possible from surgical electrodes when High Frequency (HF) surgical and physiological monitoring equipment used simultaneously on the same patient. Needle monitoring electrodes should not be used under any circumstances. Position patient leads in such a way that contact with the patient or other leads is avoided. Use monitoring systems incorporating HF current-limiting devices.

Operating Modes
The MAG operates in five modes: STANDBY, READY, RF ON, ERROR and FAULT.

MAG Operating Mode Function
STANDBY Mode STANDBY Mode is active after the MAG has been powered ON and

successfully passed the self-tests. In STANDBY Mode, the footswitch and the Handpiece may be connected. After the Handpiece has been connected, the MAG will switch to the READY Mode.
READY Mode| READY Mode is active after at least one Handpiece has been connected in the STANDBY Mode, or from the RF ON Mode after RF has been stopped. If the MAG detects that a Handpiece has been disconnected, the MAG will switch back to STANDBY Mode if no Handpieces are connected.
RF ON Mode| Caution: Ensure that the Handpiece is positioned on patient tissue before pressing RF ON.
To activate RF energy, use the touchscreen display, OR the footswitch. When the RF Activation is stopped, the RF output timer will be reset in preparation for the next ablation cycle—and the MAG will return to READY Mode.
If the MAG detects that no Handpieces are connected, the MAG will switch back to STANDBY Mode.
ERROR Mode| The MAG will enter the ERROR Mode if it detects any recoverable error conditions during any Mode except for the FAULT Mode (described below). The MAG displays the corresponding error message.
If the selected Handpiece is disconnected, the MAG will transition from Error Mode to STANDBY Mode or READY Mode if another Handpiece is connected.
FAULT Mode| The MAG will enter the FAULT Mode if a non-recoverable error condition is detected during any operating mode or as a result of failing a non-recoverable self-test.
The MAG is inoperable (and RF energy is disabled) in the FAULT mode. To clear the FAULT Mode, turn the MAG power OFF and then ON again.

TROUBLESHOOTING

Use the following sections to help troubleshoot possible problems with the MAG.

Display Problems

  • If the active device cannot be selected using the Touch Screen, disconnect all handpieces except the device that is required. At the physician’s discretion the lesion may be continued using default settings.
  • If RF activation or deactivation is not working via the Touch Screen, use the Footswitch to activate and de-activate RF.
  • If the display is not working, connect a Remote display using the HDMI cable.
  • If the Remote display (HDMI) is not working, disconnect then re-connect the HDMI cable to ensure that the connector is fully inserted.
  • If the Touch Screen or Remote display is not working use the power entry module ON/OFF switch to power off the generator, then power on again.
  • The default power settings may display 0W while in Sense Mode, move to Ablate Mode and verify the default settings are correct. If they need to be reset, press the default button in the settings menu.

Handpiece Not Functioning as Expected
Check for the following:

  • Ensure that only Handpieces, footswitch, and other products supplied by AtriCure and indicated for use with the MAG are used.
  • Check that the Handpiece is plugged into the appropriate receptacle on the MAG. Connectors for AtriCure Handpieces are not interchangeable. For example, a pen Handpiece connector will not fit into the receptacle for a clamp Handpiece.
  • After the Handpiece has been plugged in, check to see that the corresponding Handpiece is illuminated on the display screen. On some of the display screens, the name of the Handpiece (e.g., “Pen” or “Clamp”) is also displayed at the top of the screen.
  • If needed, review the Handpiece instructions for use to make sure that the Handpiece capability is consistent with the attempted use. For example, if bipolar electrodes are needed to perform ablation, make sure the Handpiece has this capability.
  • Check the Handpiece for any loose wires or damage.
  • In the event of an emergency, use the power entry module ON/OFF switch to power down the generator, unplug the handpiece, or remove the power cord from the power outlet.

ELECTROMAGNETIC OR OTHER INTERFERENCE

The MAG has been tested and found to comply with the limits for medical devices in IEC 60601-1-2. These limits are designed to provide reasonable protection against harmful interference in a typical medical installation.
The MAG generates and can radiate RF energy and, if not installed and used in accordance with the instructions, may cause harmful interference to other devices in the vicinity.
However, there is no guarantee that interference will not occur in a particular installation. If the MAG does cause harmful interference to other devices—which can be determined by turning the generator power off and then on again—try to correct the interference by one or more of the following measures:

  • Reorient or relocate the receiving device.
  • Increase the separation between the MAG and the other devices.
  • Connect the MAG into an outlet on a circuit different from that to which the other device(s) are connected.
  • Contact the AtriCure service representative for help.

Use the following sections to troubleshoot specific types of interference, including monitor (display) interference, neuromuscular stimulation, and pacemaker interference.

Monitor (Display) Interference
Continuous Interference

  1. Check the Power Cord connections for the MAG.

  2. Check all other electrical equipment in the operation room for defective ground conditions.

  3. If the electrical equipment is grounded to different objects, rather than a common ground, voltage differences can appear between the two grounded objects. The monitor may respond to these voltages. Some types of input amplifiers can be balanced to achieve optimum common mode rejection and may possibly correct the problem.
    Interference Only When MAG is Activated

  4. Check all connections to the MAG, and connections to the active handpiece, to look for possible metal-to-metal sparking.

  5. If interference continues when the MAG is activated and while the electrode is not in contact with the patient, the monitor is responding to radio frequencies. Some manufacturers offer RF choke filters for use in the monitor leads. These filters reduce interference while a generator is activated. RF filters minimize the potential for an electrosurgical burn at the site of the monitor electrode.

  6. Check that the ground wires in the operating room are electrically consistent. All ground wires must go to the same grounded metal with wires that are as short as possible.

  7. If the above steps do not remedy the situation, have the MAG checked by qualified service personnel.

PREVENTIVE MAINTENANCE

The MAG does not require preventative maintenance and does not have any serviceable parts. The MAG does not require preventative maintenance with regard to ELECTRICALMAGNETIC DISTURBANCE during the EXPECTED SERVICE LIFE.
