Functional and Advisory Limits
Functional Limits:
The ClosureRFG radiofrequency generator measures catheter and
treatment parameters (temperature, impedance, RF power, and time) before and during
RF treatment. These measured values must be within functional limits that are set to detect
a catheter or generator malfunction before RF treatment can start or continue. The
parameters are specific to the type of catheter attached.
If a value violates functional limits:
• RF treatment is prevented or stopped.
• An alarm tone (for high-temperature and high-power parameter functional limits) or
an informational tone (for all other parameter conditions) sounds.
• During RF treatment, the gauge related to that parameter turns gray.
• An alarm message is displayed indicating the problem. The operator can press the
Green Check Mark button, or allow it to clear itself in 30 seconds.
• Medium-priority errors also show the special icon
and sound a tone.
The operator must take some action (for example, acknowledge a prompt, replace the
catheter) to clear the functional-limit violation.
Advisory Limits:
If parameters are measured outside the advisory limits, but within the
functional limits, a descriptive message appears and a tone sounds. Since these
measurements are within the range of functional limits, treatment is still allowed.
Caution
Operation of the ClosureRFG generator during an advisory limits warning may cause suboptimal
RF treatment. The ClosureRFG generator may not allow treatment to continue if the cause of the
advisory message is allowed to persist.
• Advisory messages automatically clear when conditions causing the messages are
gone.
