Ablation Zone Dimensions
The below table depicts the ablation zone sizes for each device:
Ablation Zone Dimensions
5│10 SpineSTAR Ablation Instrument
(Note: All lengths have a tolerance of ±1mm)
10│15 SpineSTAR Ablation Instrument
(Note: All lengths have a tolerance of ±1mm)

Caution
:
Excessive ablation may create heat within the spine and adjacent neural tissue.
STAR Tumor Ablation Procedure
By pressing the BLUE button on the hand switch, the user can start ablation when the SpineSTAR
Ablation Instrument is properly placed:
1.
Both thermocouple temperatures are displayed in amber (≥ 30°C). Note, temperatures
are displayed in blue when temperature is <30°C.
2.
Electrode is extended to the desired location (impedance is within range).
During RF delivery, a RF Enable tone will sound. If the temperature for proximal TC is greater than
45°C, High Temperature tone will replace the normal RF tone.
The user can stop RF delivery by pressing the Blue button on the hand switch again.
RF will also automatically turn off if any of the following criteria are met:
1.
RF Cycle Time reaches 00:00.
2.
Maximum tissue impedance (1000Ω) is achieved.
