Summary
The Post-Market Clinical Follow-Up trial is a prospective, multi-center, open-label, single-arm clinical follow-up study designed to provide long-term safety feasibility, effectiveness and performance of the FARAPULSE Pulsed Field Ablation System for the treatment of Paroxysmal Atrial Fibrillation (PAF).
