BTG Visual-ICE - Cautery Control for 2.1 CX Needles

4-24 User Manual
• When the cautery function has terminated, the timer indicates the status as Stopped and the
temperature display indicates that the needle is Cooling.
5. If desired, press the Start button to re-initiate track ablation on additional sections of the needle
track.
6. After completing track ablation, carefully remove the needle.
CAUTION. Do not remove the needle from the patient until needle cooling is complete.
Removing the needle while it is still hot presents a risk of injury to adjacent tissue and/or organs.
• If needle sticking is experienced, use a slight, gentle twist of the needle followed by slow
withdrawal.
• During needle removal, watch for the 10 mm wide Active Zone Indicator on the needle to
guide needle withdrawal. The Active Zone Indicator is a marked band along the needle shaft,
located 20 mm distal to the heating portion of the needle.
