1-8 User Manual
•
Position the Visual-ICE System in a manner to avoid draping needle tubing across the patient.
Needle tubing may become extremely cold when conducting freeze cycles during a cryoablation
procedure. It is important that a patient’s skin is protected from direct contact with needle tubing
to avoid the potential for thermal injury to the patient. Ensure an appropriate insulating barrier is
placed as needed (such as towels) or other method is employed to prevent needle tubing from
touching a patient’s skin.
•
Active thawing produces heat along the distal needle shaft. Use care to avoid thermal injury to
non-targeted tissues.
• Track ablation produces heat along the distal needle shaft and may warm the needle handle.
Use care to avoid thermal injury to non-targeted tissues. When conducting FastThaw or when
conducting Cautery for Track Ablation, be alert for the Active Zone Indicator as the needle is
withdrawn to prevent unintended tissue damage from the hot needle.
• If a needle appears to be blocked, press the
Thaw
button to thaw the needle for at least one
minute to clear the blockage.
•
Take precautions to avoid potential electrostatic discharge. If an electrostatic discharge occurs
after touching the monitor, the screen may flicker and MTS temperature readings may be
inaccurate for a few seconds. The system will remain functional and the monitor will refresh
momentarily.
1.7.4 After Use
• Depressurize the system after the cryoablation procedure is completed (reference Section 4.4).
•
Warn people near the system about loud noise before manually depressurizing the system.
•
Cut the needle and MTS tubing and dispose of used needle and MTS in a biohazard container in
accordance with hospital and safety regulations.
• Clean the Visual-ICE System per the instructions in Section 6.2. Do not use cleaning agents such
as Betadine or bleach solution, which may damage the touch screen.
• To avoid confusion at the beginning of a new procedure, ensure that the
o Manual Vent Valve is closed
o
Argon Shutoff Valve is in the GAS ON position
