Channel button – Identifies the active channel(s)�
> Advanced Channel Controls: Pressing and holding the Channel button provides options to change
the needle type selected for that channel, link two adjacent channels together for simultaneous
operation, and program freeze – thaw cycles�
Channel labeled ALL – Allows testing, freezing, and thawing on ALL active channels simultaneously�
Press the button for the desired function (Test, Freeze, or Thaw) on this channel to activate that
function on all needles simultaneously�
Test button – Begins the Needle Integrity and Functionality Testing that is required prior to using any
cryoablation needle� No other controls are enabled until needle testing is complete�
Tested button - Following completion of Needle Integrity and Functionality Testing, the button
displays a check mark and the remaining control buttons on the channel become active�
Freeze button – Begins a Freeze phase at the selected freeze intensity�
Freeze Intensity drop-down menu – Provides an option to adjust the freeze intensity from 100 % to 5 %
or to select "Stick" intensity�
NOTE: The Visual-ICE Cryoablation System controls freeze intensity by adjusting the duration of argon flow
over each 10 second block of time (e�g�, 30 % freeze intensity freezes for 3 seconds and idles for 7 seconds)�
Thaw button – Begins a Thaw phase�
> Advanced Thaw Controls: Pressing and holding the Thaw button provides an option for enabling
FastThaw and an option for enabling track ablation via the Cautery Function button� The FastThaw
Function and cautery function are available only on CX-type cryoablation needles�
FastThaw Function button – Begins a FastThaw phase�
> Advanced Thaw Controls: Pressing and holding the FastThaw Function button provides an option to
