Note: The orientation marker which is located on the Balloon Catheter shaft is not visible in the

endoscopic view but is always positioned opposite the central lumen "blind spot".
Note: Adjustment to the endoscopic image on the flat panel display is not essential but is

recommended as a guide prior to performing ablations in a particular vein.
8. Observe ICE and/or fluoroscopic images to ensure that the maximum diameter of the Balloon is antral to the
pulmonary vein ostium.
9. Phrenic nerve pacing is recommended to avoid injury to the phrenic nerve. One method for conducting pacing
is as follows: Pace from the superior vena cava (SVC) once the Balloon is inflated near the RSPV (and if desired,
RIPV) to assess the location of the phrenic nerve by observing any "capture" at the target energy delivery site. It
is recommended that pacing be conducted at high output to ensure capture of the phrenic nerve.
10. When pacing prior to energy delivery, the site of diaphragmatic stimulation (and therefore the approximate
phrenic nerve location) can be compared via fluoroscopy or ICE with the target energy delivery site. Do not
deliver energy to any area where there is phrenic nerve capture.
