• Connect the opposite end of the auxiliary gas supply line to the second argon cylinder by securing the end of
the auxiliary line to the cylinder connection.
• Open the primary cylinder valve first and use this cylinder until depleted. Do not open the cylinder valve on the
second cylinder until the initial cylinder has been depleted.
• Reference the Changing Gas Cylinders during a Procedure Section for instructions on changing the gas
cylinder during a procedure, if the second cylinder is also depleted during the procedure.

WARNING: Have sufficient argon gas available to conduct the planned cryoablation procedure: the number and
type of needles, gas cylinder size, pressure and rate of gas flow affect the required gas volume (reference the
External Gas Supply Section for gas purity requirements). At least one full spare cylinder should be available for
each treatment.
3. Ensure the Gas Indicator (Screen 9) displays the minimum working pressure before initiating a procedure
(Table 7). The Gas Indicator should indicate the pressure to be in the green range. If the system detects that
the pressure reading for either gas cylinder is less than 50 psi (3.4 bar, 0.344 MPa), a message displays on the
Navigation Tool Bar (Screen 9). Connect the gas cylinders to the Visual-ICE MRI Cryoablation System.
