Controls and Displays
6-9
To select the proper control mode, follow these steps:
1.
Ensure that the Controller is in the READY mode.
"
Note
The control mode can only be changed when the Controller is in the
READY mode.
2.
Press the CONTROL Button to select the appropriate control mode. The CONTROL
Indicator LEDs display the selected mode.
Selecting the Power Output
To deliver RF power, it is necessary to select a Controller power output. This is true for
both Temperature Control mode and Power Control mode.
"
Note
Use Lower Power First - When first delivering RF energy, begin by using a low
power setting (i.e., 50W). If the created lesion is unsuccessful or inadequate,
incrementally increase the power output with successive ablation attempts to minimize
the potential for thrombus formation and/or inadvertent damage to cardiac tissues.
Controller in Temperature Control Mode - Catheter(T°) Connected
The Controller is automatically entered into the Temperature Control mode and the RF
power setpoint is the maximum amount of power that the Controller can access to achieve
the desired catheter tip temperature. If the RF power setpoint is equal to or greater than the
amount of power necessary to achieve the desired catheter tip temperature, then the
Controller supplies the appropriate amount of power to achieve the temperature setpoint.
The Controller only supplies as much RF power as necessary to achieve the desired catheter
tip temperature.
If the RF power setpoint is less than the amount of power required to achieve the desired
catheter tip temperature, then the Controller may not be capable of achieving the desired
catheter tip temperature and thus the measured temperature is less than the desired catheter
tip temperature.
Controller in Power Control Mode - Catheter(Non-T) or Catheter(T°) Connected
If a Catheter(Non-T) or Catheter(T°) is connected, the Controller is manually placed into
the Power Control mode, then the RF power setpoint corresponds to the actual amount of
power that is delivered to the tissue, unless the upper temperature limit is exceeded, in
which case, the Controller reduces and/or ceases delivery of set power.
Controller in Power Control Mode - Catheter(T°) Connected
If using a Catheter(T°) with the Controller in the Power Control mode, the
TEMPERATURE Display shows 85
o
C when the Controller is in the READY mode and
displays measured temperature when the Controller is in the ON, CALIBRATE, and DONE
operational modes.
