A Study For Treatment of Paroxysmal Atrial Fibrillation (PAF) With the OMNYPULSE Catheter and the TRUPULSE Generator

Inclusion Criteria: * Diagnosed with Symptomatic paroxysmal atrial fibrillation (PAF) defined as as atrial fibrillation (AF) that terminates spontaneously or with intervention within 7 days of onset. This PAF is considered to be symptomatic if symptoms related to AF are experienced by the participant * Selected for AF ablation procedure by pulmonary vein isolation (PVI) * Willing and capable of providing consent * Able and willing to comply with all pre-, post- and follow-up testing and requirements Exclusion Criteria: * Previously known AF secondary to electrolyte imbalance, thyroid disease, or reversible or non-cardiac cause (example, documented obstructive sleep apnea, acute alcohol toxicity, morbid obesity \[body mass index greater than {\>} 40 kilograms per meter square {kg/m\^2}\]), renal insufficiency (with an estimated creatinine clearance less than (\<) 30 milliliters per minute per 1.73 meter square \[mL/min/1.73 m\^2\]) * Previous left atrium (LA) ablation or surgery * Participants known to require ablation outside the PV region (example, atrioventricular reentrant tachycardia, atrioventricular nodal re-entry tachycardia, atrial tachycardia, ventricular tachycardia and Wolff-Parkinson-White) * Previously diagnosed with persistent AF (\> 7 days in duration) * Severe dilatation of the left atrium (LA) (left anterior descending artery \[LAD\] \>50 millimeter \[mm\] antero-posterior diameter in case of transthoracic echocardiography \[TTE\]) * Presence of LA thrombus * Severely compromised left ventricular ejection fraction (left ventricular ejection fraction \[LVEF\] \<40 percentage \[%\]) * Uncontrolled heart failure or New York Heart Association (NYHA) Class III or IV * History of blood clotting, bleeding abnormalities or contraindication to anticoagulation (heparin, warfarin, or dabigatran) * History of a documented thromboembolic event (including transient ischemic attack \[TIA\]) within the past 6 months * Previous percutaneous coronary intervention (PCI) / myocardial infarction (MI) within the past 2 months * Previous coronary artery bypass grafting (CABG) in conjunction with valvular surgery, cardiac surgery (example, ventriculotomy, atriotomy) or valvular cardiac (surgical or percutaneous) procedure * Unstable angina pectoris within the past 6 months * Anticipated cardiac transplantation, cardiac surgery, or other major surgery within the next 12 months * Significant pulmonary disease (example, restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces severe chronic symptoms * Known significant pulmonary vein (PV) anomaly that in the opinion of the investigator would preclude enrollment in this study * Prior diagnosis of pulmonary vein stenosis * Pre-existing hemi diaphragmatic paralysis * Acute illness, active systemic infection, or sepsis * Presence of intracardiac thrombus, myxoma, tumor, interatrial baffle or patch or other abnormality that precludes catheter introduction or manipulation * Severe mitral regurgitation * Presence of implanted pacemaker or implantable cardioverter-defibrillator (ICD) or other implanted metal cardiac device that may interfere with the pulsed electric field energy * Presence of a condition that precludes vascular access (such as Inferior Vena Cava \[IVC\] filter) * Significant congenital anomaly or a medical problem that in the opinion of the investigator would preclude enrollment in this study * Categorized as vulnerable population and requires special treatment with respect to safeguards of well-being * Current enrollment in an investigational study evaluating another device or drug * Women who are pregnant (as evidenced by pregnancy test if pre-menopausal), lactating, or who are of child-bearing age and plan on becoming pregnant during the course of the clinical investigation * Life expectancy less than 12 months * Presenting contra-indications for the devices used in the study, as indicated in the respective Instructions For Use (IFU) * Known contraindication for magnetic resonance imaging (MRI) such as use of contrast agents due to advanced renal disease, claustrophobia etcetra. (at principle investigator \[PI\] discretion) * Presence of iron-containing metal fragments in the body * Known unresolved pre-existing neurological deficit * Known uncontrolled significant gastroesophageal reflux disease (GERD)
