o
When the temperature gets to 95°, a tone will sound signifying that target temp has been reached. The the timer
will begin to count up.
o
When it reaches the correct time, a “Finished” tone will be heard.
o
Once the tone is heard, press the foot pedal (yellow) to stop the RF energy.
•
To shut off RF energy, depress the foot pedal (yellow).
•
The most important predictor of the completeness of the ablation is having reached the desired target temperature for
the prescribed amount of time at set deployments of the electrodes of the Handpiece. For more information and
guidance, see §11 and §12.
•
Retract the Handpiece’s electrode arrays and move to the next fibroid. Continue until all the fibroids have been treated.
•
Immediately following a completed ablation, the user is ready to cauterize the Handpiece tract.
•
When the Handpiece is removed, perform Coag as described in §9.6.
10.12.
Operation of System During Coag
•
Retract the Handpiece’s electrode arrays completely by sliding the electrode array knob to its mechanical stop.
•
Depressing the right foot pedal (blue) activates the Ready Coag. The settings allow for 1-20 (power level), and default
is always set to 12 or the last setting chosen.
•
The Handpiece tip should be allowed to cool for 60 seconds after the ablation has stopped prior to removing it from
the target tissue
•
When ready to Coag, turn the RF energy on by pressing and holding the foot pedal (blue). The user judges proper
coagulation by visual observation and experience.
•
Observe the Coag on the laparoscope and pull back the device slowly until the tip is visible.
•
Turn off RF power when track coagulation is completed by releasing the foot pedal (blue).
•
Note: During Coag mode the user may experience char on the tip. A sterile disposable wipe moistened with 70/30
isopropyl alcohol may be used to clean the trocar tip. Dry the Trocar or allow it to evaporate before use. Before
Handpiece insertion into peritoneal cavity, deploy electrode arrays and inspect.
10.13.
After the Procedure
•
Disposable items should be disposed of according to normal hospital practices. Additionally, follow local governing
ordinances and recycling plans regarding disposal or recycling of disposable items.
•
Clean the non-disposable Acessa components according to the directions in §6 or in their Instructions for Use.
10.14.
Shutting Down the System
•
To shut down the system, press the On/Standby button for approximately 4 seconds. Then turn the switch on the rear
panel to Off (O).
WARNING: Always verify that the electrode arrays are retracted fully before withdrawing the
Handpiece to avoid patient injury!
