Caution: Continuous irrigation is not required for the
Prostiva RF procedure. Continuous irrigation can cool down
the needle temperatures, which may reduce the optimal lesion
effect.
Note: To keep the urethra cooled, irrigate with small flushes of
irrigation fluid (approximately 0.5-1.0 ml). It is recommended
that continuous flushing only be used during positioning and
visualization then turned off.
Note: To drain bladder, open stopcock connected to the
aspiration position.
13. When the lesion treatment is complete, confirm that the
"Lesion Complete" message appears on the screen display
(Figure 4-14), and fully retract the hand piece trigger
mechanism (Figure 4-13).
a. Move the trigger mechanism fully forward until it moves into
the fully retracted position; this fully retracts the needles
and the shields.
b. Confirm that the trigger mechanism is fully up and that the
needle retraction window shows solid white and no blue.
c. Remove or reposition the hand piece as you deem
appropriate.
Warning: Do not continue, reposition, or remove the
hand piece until you have confirmed that the trigger
mechanism is fully forward. Failure to place the trigger
mechanism into the needles-fully-retracted position can leave
the needles and shields partially deployed. This can result in
possible patient injury if the hand piece is repositioned or
removed from the urethra.
Note: If the telescope becomes damaged or otherwise
non-functional during a treatment, it is recommended that the
lesion be completed and the needles fully retracted prior to
removing the entire hand piece from the patient. If there is a
loss of illumination due to a light source or camera
malfunction, the hand piece does not require removal. A spare
telescope and fiber-optic light source/cable are
recommended.
