Figure 9. Locking Needle into Channel
5� To allow for easier identification of the needle when multiple cryoablation needles are used during a cryoablation
procedure, it is recommended to place a Needle Channel ID sticker on the needle tubing�
NOTE: Contact Boston Scientific Technical Assistance Center to order Needle Channel ID sticker for the cryoablation
needles�
6� Repeat Steps 2 through 5 for each cryoablation needle that will be tested�
CAUTION: Boston Scientific recommends that only needles of the same type be placed together in a single channel�
Do not combine i-Thaw Function capable needles with non-i-Thaw Function capable needles in the same channel�
Additionally, using needles of differing types in a channel may affect the accuracy of the Gas Indicator�
CAUTION: If the Visual-ICE Cryoablation System detects that helium gas is connected, the system defaults to helium
thaw mode and i-Thaw Function, FastThaw Function, and cautery function capabilities are disabled�
NOTE: The Visual-ICE Cryoablation System displays a message if one or more needles without i-Thaw Function
capability are connected and helium gas is not connected to the system� Ensure helium gas is connected to the
system to use active thaw without i-Thaw Function�
