ClosureRFG Radiofrequency Generator

12-1

Glossary of Terms

Advisory Limits

- Limits on parameters, such as temperature, impedance, RF power, time,

or a combination of these, outside of which RF treatment is not optimal and corrective
action is suggested.

Alarm Tone

- The alarm tone sounds when the unit detects an alarm condition for the

connected catheter.

Catheter

- An approved Covidien RF delivery or RF powered accessory that can be

attached to the ClosureRFG radiofrequency generator.

Default

- A value for a setting that is assigned automatically by the ClosureRFG generator.

Default values remain in effect unless altered in the ClosureRFG Generator Settings screen.

Device

- The term used in generator messages to refer to catheters and stylets.

EMC

- Electromagnetic Compliance.

EMI

- Electromagnetic Interference.

Functional Limits

- Limits on parameters, such as temperature, impedance, RF power,

time, or a combination of these, outside of which RF delivery will not start, or stops
immediately.

Impedance

- The effective resistance of the Covidien ClosureFast endovenous

radiofrequency catheter heater, or the Covidien ClosureRFS endovenous radiofrequency
stylet electrodes, expressed in ohms.

Informational Tone

- The informational tone sounds if the unit detects that a parameter

is between the advisory and functional limits for the connected catheter. It is also used
during RF treatment and for button presses.

LCD

- Liquid-Crystal Display, the touch screen.

Parameter

- The measured quantities that govern the RF treatment algorithm—

temperature, impedance, RF power, and/or time.

Persistent Settings

- Operator-adjustable settings that retain their value when the

ClosureRFG generator is turned off, such as screen brightness and tone volume settings.

POST

- Power-On Self-Test.

Power Limit

- Maximum RF power that the catheter can deliver.

Power Measurement

- Current RF power being delivered.

Power Set Point

- The desired RF power.

Procedure

- All the cycles of an RF treatment at one site.
