The Post-Approval Study (PAS) is a prospective multi-center, non-randomized, single arm,
controlled,unblinded clinical study designed to provide long-term safety and effectiveness of
the Arctic Front® Cardiac CryoAblation System.

Safety and effectiveness will be evaluated against pre-specified performance criteria as
determined by the sponsor and FDA. The criteria set in this study have been previously used
to demonstrate safety and effectiveness in cryoablation and radio-frequency ablation for the
treatment of paroxysmal atrial fibrillation.

The analyses of the primary effectiveness objective will take place once all the subjects
with a study cryoablation procedure attempt have reached 36 months of follow-up
post-cryoablation procedure. The analysis of the primary safety objective will take place
once all the subjects with a study cryoablation procedure attempt have reached 12 months of
follow-up post-cryoablation procedure. The analyses for the secondary objectives will take
place once all subjects with a study cryoablation attempt have reached 36 months of follow-up
post-cryoablation procedure.
