2026年8月26日 更新者: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.

実験的:FARAFLEX Mapping and Pulsed Field Ablation (PFA) System
Participants undergo a catheter procedure using the FARAFLEX Mapping and Pulsed Field Ablation (PFA) System to treat atrial fibrillation. The catheter is used to map the heart's electrical signals and deliver pulsed field ablation therapy.
Catheter used to perform cardiac electrophysiological mapping and deliver cardiac tissue ablation therapy for the treatment of Atrial Fibrillation.
