Experimental: TactiCath Quartz
TactiCath Quartz treatment
Device: TactiCath Quartz treatment
Catheter ablation for the treatment of paroxysmal atrial fibrillation

Primary Outcome Measures :
  1. Electrical isolation of all 4 PVs, or in the event of a common PV, the clinical equivalent of all PVs, by the end of index procedure [ Time Frame: 30 min post ablation ]
  2. Acute procedural success and freedom from recurrence of symptomatic AF, AFL, and AT lasting longer than 30 seconds through 9 months of follow-up after a 3 month blanking period. Re-treatment for AF with ablation after 3 months is a failure [ Time Frame: 12 months post ablation ]
  3. Device-related early onset primary SAEs occurring within 7 days of the index procedure [ Time Frame: 7 days post ablation ]
