Evaluation of the FARAFLEX Mapping and Pulsed Field Ablation System in Subjects With Atrial Fibrillation (FARADIGM)

26 de agosto de 2026 actualizado por: Boston Scientific Corporation

Evaluation of the FARAFLEX Mapping and Pulsed Field Ablation System in Subjects With Atrial Fibrillation - A Global Prospective Single Arm Study

The goal of this clinical trial is to learn if the FARAFLEX™ Mapping and pulsed field ablation (PFA) System can safely and effectively treat symptomatic, drug-refractory Paroxysmal atrial fibrillation (PAF) and Persistent atrial fibrillation (PersAF). The main question it aims to answer is:

Is the FARAFLEX Mapping and PFA System a safe and effective treatment for patients?

Participants will undergo an ablation procedure using the FARAFLEX Mapping and PFA System.
