Essential Performance
The Visual-ICE Cryoablation System essential performance is defined as:
• The ability to turn on and turn off the flow of argon or helium to the connected cryoablation needles via
command inputs from the user interface
• The ability to maintain uninterrupted gas flow to user-selected needles when gas flow is turned on by the user
• The ability to uninterruptedly prevent gas flow to user-selected needles when gas flow is turned off by the user
• The ability to energize the electrical resistance heater on user-selected i-Thaw Function/cautery function
capable needles
• The ability to continuously monitor and display temperatures measured by user-selected thermal sensors
