WARNING. Warn operating room personnel prior to venting the Visual-ICE™ MRI System to
avoid startling them.
1. If you did not choose to automatically vent the Visual-ICE MRI Cryoablation System after pressing
End Procedure on the touch screen interface, perform these steps to manually vent the system:
NOTE: Reference Section 5.2, Step 13 for information on selecting the automatic venting option
at the end of the cryoablation procedure.
a. Turn the shutoff valve on the gas cylinders clockwise to close the gas cylinders.
b. Turn the Manual Vent Valve on the Visual-ICE MRI System to the OPEN position to release
the high-pressure gas from the system.
c. Turn the Manual Vent Valve to the CLOSED position after gas venting completes.
2. Disconnect the high-pressure gas supply lines from the Visual-ICE MRI System and from the gas
cylinders. Store the gas supply lines and gauge assemblies in the storage compartment provided
on the system (Figure 2-2).
CAUTION. Do not use excessive force to disconnect the gas supply lines from the system.
The connectors will not disconnect if any gas pressure remains in the system. Vent the system
completely using the Manual Vent Valve and then try to disconnect the supply lines again.
3. Cover the helium and argon inlets with the humidity plugs.
