Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Irreversible Electroporation (IRE) System

Participants with symptomatic drug refractory paroxysmal atrial fibrillation (PAF) and indicated for catheter ablation will be treated with the IRE system which includes multi-electrode circular IRE catheter and the multi-channel IRE generator.

Group Type EXPERIMENTAL

Multi-Channel Irreversible Electroporation (IRE) Generator

Intervention Type DEVICE

The multi-channel IRE Generator is intended for use during cardiac Pulsed Field Ablation (PFA) therapy. This device is used in conjunction with a compatible ablation catheter to create a closed electrical circuit capable of delivering pulsed electrical field energy.

Multi-Channel Circular IRE Catheter

Intervention Type DEVICE

The multi-channel circular IRE Catheter is indicated for use in catheter-based cardiac electrophysiological mapping (stimulating and recording) and when used with an IRE Generator, for cardiac ablation.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Diagnosed with symptomatic paroxysmal atrial fibrillation (PAF) (Physician's note indicating recurrent self-terminating atrial fibrillation \[AF\]). At least one electrocardiographically documented AF episode within twelve (12) months prior to enrollment. Electrocardiographic documentation may include, but is not limited to, electrocardiogram (ECG), Holter monitor, or telemetry strip
* Failed at least one Class I or Class III antiarrhythmic drug (AAD) as evidenced by recurrent symptomatic AF, contraindicated or intolerable to both Class I and Class III AAD
* Able and willing to comply with all pre-procedure, post-procedure, and follow-up testing and visit requirements
* Willing and capable of providing consent

Exclusion Criteria

* AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause (Example, untreated documented obstructive sleep apnea and acute alcohol toxicity)
* Previous left atrium (LA) ablation or surgery
* Participants known to require ablation outside the pulmonary vein (PV) region (atrioventricular reentrant tachycardia, atrioventricular nodal reentry tachycardia, atrial tachycardia, atrial flutter of unknown origin, ventricular tachycardia and Wolff-Parkinson-White)
* Previously diagnosed with persistent AF (greater than \[\>\] 7 days in duration)
* Severe dilatation of the LA (documented LAD \>50 millimeters \[mm\] antero-posterior diameter by transthoracic echocardiography (TTE) within 6 month prior to enrollment)
