5� Thaw thoroughly and stop all needle operation prior to removing needles to minimize the risk of tissue injury�
• If needle sticking is experienced, use a slight, gentle twist of the needle followed by slow withdrawal�
Cautery Control for Track Ablation
Needle track ablation is achieved using the cautery function in the Advanced Thaw Controls � The needle track is
ablated through the use of thermal energy� Each cautery function enabled needle (1�5 CX type needles and 2�1 CX-type
needles) is operated independently using the Cautery function button in the Advanced Thaw Controls for the channel
and port in which the needle is connected�
WARNING: Use image guidance to monitor needle location and position to avoid the risk of thermal injury/burn to
adjacent tissue/organs�
WARNING: Track ablation produces heat along the distal needle shaft� Use care to avoid thermal injury/burn to
adjacent tissue/organs�
WARNING: The needle handle may become warm during track ablation� Pay attention to the needle handle
position� Prolonged contact with warm portions of the needle handle could cause unintended thermal injury/burn
to the patient or clinician�
CAUTION: The cautery function should not be initiated if the Active Zone Indicator is visible outside the patient's skin�
NOTE: While the Visual-ICE Cryoablation System is in cautery function mode, freezing and thawing are not allowed
on any other channels�
NOTE: The cautery function is not available on the channel ALL�
Cautery Control for 1.5 CX Needles
