temperatures in the ablation area at the set temperature (target temperature). See “Device
Temperatures Buttons and LEDs” for information on how to select or deselect a temperature
into the average algorithm.
• Once the target temperature is reached the buzzer beeps for 1 second and the timer
(“TIMER (min)”) will start counting down.
• If the target temperature is not reached within 10 minutes, the RF energy delivery
automatically stops.
• If the average temperature falls below the target temperature by more than 5 degrees for
more than 5 seconds, the timer will discontinue counting down. Once the target
temperature is reached again, the timer will resume counting down.
• When the timer counts down to 0.0 minutes and the ablation cycle is complete, the
system automatically goes to Cool Down mode for 30 seconds (see below).
6.6.1 ATC Mode for Dry Devices
This mode is used when using a dry electrode like the Starburst

XL.
6.6.2 ATC Mode for Infusion Devices
This mode is used when using an Infusion Device, which utilizes micro-infusion during the
ablation process. In this mode, the power delivery is automatically controlled based on the
average of all selected temperature readings. Infusion Mode is ablation size and device model
specific. This mode provides instructions to the user on the RF Generator LCD display and
changes default settings based on the stage of the ablation. The Starburst

XLi-e is an example
of an infusion device.
6.7 Cool Down Mode:
• Once the timer (“TIMER (min)”) counts down to 0.0 minutes, the system automatically
enters into the “COOL DOWN CYCLE” mode for 30 seconds as displayed on the LCD. The
temperatures are displayed in real time.
• At completion, “COOL DOWN CYCLE COMPLETE” is displayed on the LCD. Cool down is a
measure of how robust the ablation is. Watch the temperatures during the Cool Down
mode. If the average temperature of the ablation after 30 seconds is below 55°C then it is
more likely that the ablation is under sized than if the cool down temperature is over 55°C. If
one array is significantly below 55°C then that area of the ablation is likely to be under
developed and depending on the clinical need, additional ablation in that area is
recommended.
6.8 Track Ablation Mode:
This mode allows the user to ablate the Device needle’s track. Temperatures are displayed in
this mode (and the power delivery is based on highest of all temperatures with a temperature
set point of 80°C. Note that this set point is not displayed on the RF Generator and is not
adjustable). No time information is available. An audible tone is emitted intermittently in this
mode.
• Retract the array of electrodes (tines) of the Device completely.
• Press the “TRACK ABLATION ON/OFF” button.
