Feasibility Study on the FARAVIEW Technology

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to gather data regarding the utilization of the FARAVIEW™ feature of the RHYTHMIA HDx Mapping System when used in conjunction with the FARAWAVE NAV Pulsed Field Ablation catheter in subjects undergoing catheter-based endocardial mapping and catheter-based ablation treatment of Atrial Fibrillation.

Detailed Description
-----------------
The objective of this study is to obtain First-in-Human (FIH) experience with the FARAVIEW™ technology of the RHYTHMIA HDx™ Mapping System when it is used to visualize and track the FARAWAVE NAV™ Pulsed Field Ablation (PFA) catheter in the treatment of Atrial Fibrillation (AF). The study will collect FIH data on user experience and workflow using the FARAVIEW technology to visualize and track the FARAWAVE NAV PFA catheter (part of the FARAPULSE™ Pulsed Field Ablation System). Subjects with Paroxysmal and Persistent Atrial Fibrillation will be included in this study.
