5. Connect the blue connector on one end of the 4-meter (12-foot) vacuum line to the vacuum canister.
Connect the male fitting of the three-way stopcock vacuum tube of the Probe handle. Turn the stopcock
to the off position with the "Off" indicator pointed in the direction of the vacuum source.
6. If using the Introducer, insert the stylet into the grey curved tubing to straighten it and provide pushability
for advancement.
7. Advance the Introducer to the desired anatomical location. By withdrawing the stylet the Introducer
tubing will advance in a preformed curve. The tubing will curve opposite the axial dark stripe.
8. Remove the stylet and couple the proximal magnetic fitting of the Introducer tubing to the distal
magnetic fitting of the Probe. Ensure that the dark stripe of the Introducer tubing is oriented opposite the
open side of the suction stabilizer.
9. If using the Magnetic Retriever, advance toward the Magnetic Introducer. Magnets at the distal end of
the Introducer and Retriever will couple automatically when in close proximity.
10. By pulling on the Retriever, the Introducer and connected Probe are brought into alignment with the
target tissue. Once in place, detach the Introducer from the Probe. The accessory Positioning devices
can then be coupled to the distal end of the Probe to aid in Probe manipulation and placement.
11. Turn vacuum regulator on to -500 mmHg to affix device to tissue. Turn vacuum control stopcock on to
vacuum source. Push stabilizer against tissue to complete seal. Allow vacuum to build up prior to
activating RF energy. Maintain manual pressure as required to ensure Probe/tissue contact and seal
integrity. Reduce tension on Fusion 150 around heart once suction has been applied.
12. Select the mode of ablation to enable or disable the integrated indifferent electrode. When ablating in
bipolar mode, indifferent electrode pads should be disconnected from the ESU receptacles.
= Monopolar;
13. Select up to 3 electrodes to be activated simultaneously on the ESU.
14. Activate selected electrodes by depressing the RF on/off switch on the ESU.
15. Radiofrequency energy may be discontinued by depressing the RF on/off switch on the ESU.
16. When the cycles are complete, turn vacuum control stopcock to off position prior to removing the
Stabilizer. Remove the device in the opposite direction it was advanced.
17. Upon completion of procedure, disconnect device from ESU and discard after use.
Directions for Use (Pacing/Recording Mode)
1. Inspect the System and all packaging materials carefully. Open the package using aseptic technique.
2. Connect the COBRA Fusion to the temporary external pacemaker using the non-sterile accessory
COBRA Fusion Pacing/Recording Adapter Cable. Connect the Cobra Fusion cable into the female
receptacle of the adaptor cable. Connect the two pins to the temporary external pacemaker or
recording device.
3. If required, attach 1-meter (3-foot) line from the vacuum canister to the vacuum regulator connection.
