The Charge Section controls the voltage on the capacitors and displays the accumulated
energy for ablation. The Capacitor Status Indictor displays the level of the capacitor charge
and shows, in Volts the voltage present on capacitors.
5.1.6 Ablation Delivery
After the probes have been placed and ablation parameters have been set, the User can
initiate an ablation.
NOTE: The User should observe and review messages displayed in the
Status
Panel/Message Box
for instructions.
To deliver ablation, the User must first press the
"Deliver Test Pulse"
button.
The Generator prepares for the test pulse as soon as the
Pulse Generation
screen is
accessed. When the Generator’s capacitors have accumulated the energy
required for the test pulse, the following message appears in the status panel:
"Click 'Deliver test pulse' to start."
Click the
Deliver Test Pulse
button and the Generator will deliver the test pulse,
Figure 5-44.
Figure 5-44: Deliver Test Pulse
Successful Test Pulse − If the test pulse is successful, the Generator automatically
charges the capacitors to the required voltage. The
Charge
section indicates the status of
the
Voltage
on the capacitors by progressively filling the bar Blue, from bottom to top. This
might require up to 30-40 seconds. When the capacitors are fully charged the status panel
displays "Device ready. Click arm button to ARM the device."
Unsuccessful Test Pulse − If the test pulse is unsuccessful, the system will indicate a fault
condition. The fault condition will guide the User to check the probe connections to ensure
that the probes are connected to the Generator.
If the fault condition indicates impedance is too low, the User will be instructed to check the
probe placement in the tissue to ensure that the probes are placed appropriately and that
the probes are not touching.
