Repeat Ablation of Persistent Atrial Fibrillation, including Mitral Isthmus Catheter Ablation, with the FARAPULSE Pulsed Field Ablation System.

The FARAPULSE™ Pulsed Field Ablation System is indicated for the treatment of symptomatic atrial fibrillation.

The FARAWAVE Catheter is indicated for the isolation of pulmonary veins and posterior wall in the treatment of drug-refractory, recurrent, symptomatic paroxysmal and persistent atrial fibrillation. The FARAWAVE Catheter is also indicated for the for the isolation of pulmonary veins and posterior wall in the treatment of persistent atrial fibrillation as an alternative to anti-arrhythmic drug (AAD) therapy as an initial rhythm control strategy.

The FARAPOINT™ PFA Catheter is indicated for use as an adjunctive device for 1) the creation of an ablation line between the inferior vena cava and the tricuspid valve and/or 2) Mitral Isthmus, when the FARAWAVE Catheter is used in the endocardial treatment of persistent atrial fibrillation (episode duration no greater than 12 months).
