FREQUENTLY ASKED QUESTIONS
Q:
DO I NEED TO USE A GROUNDING PAD WHEN LESIONING IN
DUAL-ELECTRODE MODE?
A: A grounding pad is still required for the initial Sensory and Motor stimulation, but not when creating
the dual lesion. When creating a lesion using the Dual-Electrode setting, one of the electrodes is the
set temperature electrode (controlling electrode) while the other electrode is passive and serves to
complete the circuit.
Q:
WHILE LESIONING IN DUAL-ELECTRODE MODE AT A SET TEMPERATURE OF
90 °C, SOME CHANNELS DO NOT REACH THE SET TEMPERATURE. WHY?
EXAMPLE (TWO DUAL LESIONS): PORT 1 IS AT 85 °C, PORT 2 IS AT 90 °C.
PORT 3 IS AT 75 °C AND PORT 4 IS AT 90 °C.
A: One electrode can be warmer than the other. The NT2000iX™ RF generator will automatically
select the electrode with the higher temperature to be the controlling, or active electrode. The active
electrode will achieve set temp while the passive electrode will often be lower than set temp due to
factors such as proximity to bone, blood vessels or other fluid (e.g., lidocaine).
Q:
WHAT IS THE DIFFERENCE BETWEEN BIPOLAR AND DUAL-ELECTRODE
ON ABBOTT RF UNITS?
A: Duel-electrode refers to two electrodes and two needles. Bipolar refers to a special needle with two
electrodes on the shaft.
Q:
WHEN PERFORMING SENSORY AND MOTOR STIMULATION USING ABBOTT
RF NEEDLES, IS THE CURRENT CARRIED BY THE ENTIRE ACTIVE TIP (E.G.,
10 MM) OR JUST THE VERY TIP OF THE NEEDLE?
A: The entire active tip.
