11. If the Guide incorporates a snap
feature, refer to steps 13-14 for
instrument exchange.
12. If the Guide incorporates a press
feature, refer to steps 15-19 for
instrument exchange.
INSTRUMENT EXCHANGE (SNAP
GUIDE)
13. Prior to attaching the Guide to the
ISOLATOR, unclamp the proximal end
of the leader from the sterile drape.
14. While holding the Guide as shown, in
the illustration below, insert the
Instrument Attachment Pin (Figure 2)
into the ISOLATOR attachment tip
(Figure 1). Once Guide is attached, do
not attempt to remove by forcibly
pulling on Guide.
INSTRUMENT EXCHANGE (PRESS
GUIDE)
15. If using an AtriCure Instrument Press
Guide, attach the guide to the distal tip
of the ISOLATOR per standard
surgical technique.
16. Use the guide to facilitate the
placement of the ISOLATOR in the
previously created positioning plane.
17. Carefully remove the guide from the
distal jaw after ISOLATOR placement.
NOTE: The Press Guide is to be
removed prior to ablation. (Refer to
Step 28)

NOTE: The accessory ribbon allows
the surgeon to create a dissection
plane in one direction (inferior or
superior) and maneuver the tape and
leader through the dissection plane so
that an instrument (clamp) can be
used from the opposite direction.
18. If it is required to reverse the direction
of device placement, the accessory
ribbon is attached to the distal pocket
of the primary transfer tape.
19. After creation of the dissection plane,
pull the distal end of the primary tape
while providing counter traction on the
proximal end of the accessory ribbon
so that the leader is pulled through the
dissection plane.
ABLATION
NOTE: A minimum tissue incision of
12 mm is recommended for insertion
of the ISOLATOR.
20. Place the targeted tissue between the
Distal and Proximal Jaws.
21. Squeeze the Closure Lever to close
the Jaws. Ensure that no target tissue
extends beyond the Indicator Line on
either the Distal or Proximal Jaws or
into the Jaw Heel.
22. Activate the ASU by depressing the
footswitch.
When the ASU is activated, the ASU
will emit an audible tone indicating that
current is flowing between the Jaws of
the ISOLATOR.
When the continuous tone switches to
intermittent, release the footswitch.
