SHORT TITLE OF 
STUDY: 
PersAFOne II 
(pronounced per-'se-fa-nē 2) 
PROTOCOL NUMBER: 
CS1335, Revision B 
OBJECTIVE: 
The objective of this safety and feasibility study is to assess 
whether the endocardial creation of electrically nonconductive 
lesions via PEF catheter ablation applied using the FARAPULSE 
Cardiac Ablation System Plus is a feasible and safe treatment for 
PersAF and associated AFL 
CLINICAL HYPOTHESIS: 
Endocardial creation of electrically nonconductive lesions in 
cardiac tissue via PEF catheter ablation using the FARAPULSE 
Cardiac Ablation System Plus is a feasible and safe treatment for 
PersAF. 
NAME OF 
INVESTIGATIONAL 
DEVICES: 
FARAPULSE Cardiac Ablation System Plus 
• FARAWAVE™ Pulsed Field Ablation Catheters 
• FARAPOINT Pulsed Field Ablation Catheter 
• FARASTAR™ Pulsed Field Generator (and accessories) 
• FARADRIVE™ Steerable Sheath 
STUDY OVERVIEW: 
This is a prospective, multi-center safety and feasibility study in 
subjects with persistent AF. Subjects will undergo percutaneous 
PEF ablation for pulmonary vein isolation as well as cavotricuspid 
isthmus interruption and other left atrial ablations at the 
investigator’s discretion. Subjects will then be followed at 30 
days, 60 ± 15 days, 6 months and 12 months for adverse events, 
recurrence of arrhythmia after a 90 day blanking period and other 
relevant outcome measures. 
STUDY POPULATION 
Subjects with documented symptomatic persistent AF (AF 
duration 7 – 365 days) and a 24-hour Holter monitor showing 
continuous AF within 90 days prior to the enrollment date; who 
are refractory or intolerant to at least one Class I/III antiarrhythmic 
agent. 
PLANNED 
ENROLLMENT: 
Up to 60 subjects 
CLINICAL SITES: 
Up to 4 clinical sites in Europe

DURATION OF 
PARTICIPATION: 
Subjects will be followed at 30 days, 60 days, 6 months and 12 
months with a 90-day Blanking Period for recurrent atrial 
fibrillation, atrial flutter or atrial tachycardia following the Index 
Procedure. 
Reablation with the study device(s) during the Blanking Period is 
permitted but does not extend either the Blanking Period or the total 
follow-up interval. 
The enrollment period is estimated to take 9 months and subjects 
will be followed for up to 12 months. The total study duration will 
be approximately 21 months. 
PLANNED PROCEDURE: 
Index Procedure: 
• Subjects will undergo an attempt to isolate all pulmonary 
veins or their anatomic equivalent. 
• Subjects with a past history of atrial flutter, who are at risk 
of atrial flutter, who present with atrial flutter during the 
Index Procedure or who have inducible cavotricuspid 
isthmus-mediated (typical) flutter may undergo ablation of 
the cavo-tricuspid isthmus at the discretion of the 
investigator. 
• Additional left atrial lesions may be made at the discretion 
of the investigator including focal sites, electrical gaps and 
lines of isolation. 
60-Day Remap Procedure: 
• Subjects will undergo a remapping procedure at 60 ± 15 
days to assess the durability of the ablation lesions 
performed during the Index Procedure. 
• During this procedure, additional ablations may be made at 
the discretion of the investigator to optimize patient 
outcomes.

Atrio-esophageal fistula 
SECONDARY SAFETY 
ENDPOINTS: 
1. The Primary Safety Endpoint assessed at 7 days 
2. The proportion of subjects with a device- or procedure- 
related SAE

PRIMARY FEASIBILITY 
ENDPOINT: 
The proportion of subjects that achieve Acute Procedural Success 
(APS) defined as the percutaneous endocardial creation of a 
complete, electrically isolating set of lesions around the ostia of 
the pulmonary veins (PVI) using the FARAPULSE Cardiac 
Ablation System Plus during the Index Procedure, as clinically 
assessed by entrance and/or exit block performed ≥ 20 minutes 
after the last PVI lesion is made.

SECONDARY 
FEASIBILITY 
ENDPOINTS: 
1. The proportion of subjects who undergo the protocol- 
specified 60-Day Remapping Procedure and achieve Chronic 
Procedural Success (CPS) defined as persistent electrical 
isolation of all initially ablated pulmonary veins. Chronic 
Procedural Success will be subdivided by Index Procedure 
only CPS and Reablated CPS subjects. 
2. The proportion of attempted subjects that achieve Acute CTI 
Success, defined as the creation of bi-directional electrical 
block across the cavotricuspid isthmus using the 
investigational devices using the FARAPULSE Cardiac 
Ablation System Plus during the Index Procedure. 
3. Durability of the CTI and/or other extra-PV lesion set(s), 
when applicable. Durability is defined as unaltered integrity 
of each such lesion assessed at the Remapping Procedure. 
4. The proportion of subjects that achieve Therapeutic Success, 
defined as freedom from: 
a. Post Blanking Period through assessment: occurrence of 
AF, AFL or AT or ablation for AF/AFL/AT using the 
study device 
b. At any time: ablation for AF/AFL/AT with a 
nonstudydevice 
Therapeutic Success will be assessed from the end of the 90- 
day Blanking Period through Months 6 and 12 and will be 
subdivided by on / off AFDs(Atrial Fibrillation Drugs) post- 
Blanking Period. 
ADDITIONAL 
ASSESSMENTS: 
1. Proportion of subjects with early recurrence of atrial 
fibrillation (ERAF) by 90 days after the Index Procedure.

1. Introduction 
1.1 
Background and Rationale 
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, affecting 
approximately 2.2 million people in the United States and 4.5 million in the European 
Union.1,2. The incidence increases with advancing age, affecting 6% of the population 
over age 60 and 10% of the population over age 803,4. Age-adjusted population 
trending projects 16 million people in the United States will have AF by 20505. Atrial 
fibrillation remains a significant cause of morbidity and mortality in industrialized 
societies. The annual risk of AF related stroke is 5% per year and one of every six 
strokes diagnosed occurs in the presence of AF.6 Therefore, patients with AF require 
long-term anticoagulation to prevent embolic events. Failure to manage AF may also 
lead to anatomic and electrical remodeling of the left atrium, tachycardia-induced 
cardiomyopathy, and reduced left ventricular function (heart failure). AF remains an 
extremely costly public health burden, with annual per patient cost of care approaching 
€3000 (approximately U.S. $3200).7 
The Heart Rhythm Society (HRS) 2017 Consensus Statement on Catheter and Surgical 
Ablation of Atrial Fibrillation8defines several different stages of atrial fibrillation. 
• Paroxysmal AF (PAF): AF that terminates spontaneously or with intervention 
within 7 days of onset. 
• Persistent AF (PersAF):continuous AF that is sustained beyond 7 days. 
o Long-standing persistent AF: continuous AF of greater than 12 months’ 
duration. 
o Permanent AF: the presence of [persistent] AF that is accepted by the 
patient and physician, and for which no further attempts to restore or 
maintain sinus rhythm will be undertaken. 
Catheter ablation for the treatment of PAF is increasingly being performed as first line 
therapy for PAF and clinical evidence is accruing that this may well become an 
accepted first line treatment. 
Catheter ablation for the treatment of PersAF is complicated by the heterogeneity of the 
underlying pathophysiologic mechanisms and the generally reduced efficacy of 
ablation for continuous AF states. A small study of catheter ablation vs. antiarrhythmic 
drug treatment of PersAF found a significant advantage of ablation over AFDs.9 While 
no catheter system has received FDA or CE Mark to date for the treatment of PersAF, 
several single arm clinical investigations seeking device approvals for this indication 
are under way. 
1.2 
Irreversible Electroporation (IRE) 
Al-Sakere 200710described irreversible electroporation as a non-thermal tissue ablation 
technique in which intense short duration electrical fields are used to permanently open 
pores in cell membranes, thus producing non-thermal tissue ablation. Their study, 
using a mouse model, showed complete regression in 92% of treated tumors. IRE 
ablation has a tissue specific mechanism of ablation. The tissue injury from IRE

ablation occurs at the cellular level with loss of homeostasis leading to necrosis or 
apoptosis.11121314IRE ablation typically spares the extracellular matrix, which facilitates 
rapid wound healing.15,16,17,18,19 
Thomson 201120reported a case-series study (N=38) assessing the safety of IRE for 
treating liver, kidney or lung cancers in humans. The first four patients showed signs 
of transient ventricular arrhythmia, so subsequent patients were all treated using 
electrocardiogram (ECG)-synchronized deliver of electroporation pulses. There were 
two further arrhythmias, and two cases of inadvertent damage to neighboring organs. 
68% of tumors were completely ablated. The authors concluded that IRE is safe for 
clinical use, provided ECG-synchronized delivery is used. 
A research group led by FHMWittkampf in Utrecht has been investigating the potential 
effectiveness and safety of epicardial electroporation in AF ablation procedures using 
porcine models. Wittkampf 201121 (N=10) used a circular ablation catheter and 
showed that PVI was achieved in all animals, with no sign of stenosis at 3-week follow 
up. Van Driel 201422 (N=6) confirmed this result out to 3-month follow up. Neven 
201423 (N=5) showed that electroporation lesion depth depended on the level of 
electrical energy applied, reaching 8mm at 300 joules. 
Van Driel 2015 (N=20) showed that electroporation could create deep lesions close to 
the phrenic nerve without damage to the nerve. Neven 2014 similarly showed that 
neighboring coronary arteries were undamaged by electroporation (N= 5). These 
animal studies suggest that irreversible electroporation can safely create deep lesions in 
heart tissue when applied epicardially without harming adjacent tissues.

Summary of FARAPULSE Clinical Studies 
1.3.1 
Endocardial Ablation Studies–The IMPULSE Study 
FARAPULSE, Inc. initiated a safety and feasibility study at Na Homolce Hospital in 
Prague, Czech Republic and HopitalCardiologique du Haut-Leveque in Pessac, 
France under the “IMPULSE” Protocol, CS0188. This study is being conducted 
using the FARAPULSE Endocardial Ablation System. Forty (40) patients were 
enrolled between January and December of 2018. Thirty (30) patients were enrolled 
in Prague and ten (10) were enrolled in Bordeaux. All patients were discharged in 
good condition. One patient was treated for tamponade at the conclusion of the Index 
Procedure and the event was resolved. Three patients were re-hospitalized for atrial 
arrhythmia and all of these events were resolved. One patient experienced a 
prolonged index hospitalization due to an arteriovenous groin fistula which was 
resolved. At the conclusion of the index Procedure, all (100%) pulmonary veins 
(PVs) were isolated using the FARAPULSE Endocardial Ablation System. Thirty- 
five (35) patients have returned for the protocol-defined 3-month remapping 
procedure to assess durable PV isolation. In these patients, 70% of PVs remained 
isolated. All PVs in fourteen (14) patients remained isolated. These results support 
the safety and performance of the system.

1.3.2 
Endocardial Ablation Studies – The PEFCAT Study 
FARAPULSE, Inc. has also initiated a safety and feasibility study at Na Homolce 
Hospital in Prague, Czech Republic and HopitalCardiologique du Haut-Leveque in 
Pessac, Franceunder the “PEFCAT” Protocol, CS0267. This study is being conducted 
using the FARAPULSE Endocardial Ablation System. Seventy-one (71) patients 
have been enrolled between October 2018 and February 2020. Fifty (50) patients 
were enrolled in Prague and twenty-one (21) were enrolled in Bordeaux. All patients 
were discharged in good condition. One patient was treated for an air embolism 
during the index Procedure and the event was resolved. Five (5) patients were re- 
hospitalized for atrial arrhythmia and all of these events were resolved. One patient 
was hospitalized for chest pain and the event was resolved. Two (2) patients 
experienced a prolonged index hospitalization due to an arteriovenous groin fistula 
which was resolved. One patient that was treated with the FARAPULSE Endocardial 
Ablation System during the remap procedure had a pericardial effusion that presented 
hours after the procedure and was treated with a pericardiocentesis and resolved. Two 
patients surgery for inguinal hernias during the course of follow up. At the conclusion 
of the index procedure, all pulmonary veins (PVs) in all patients were isolated using 
the FARAPULSE Endocardial Ablation System. Sixty-five (65) patients have 
returned for the protocol-defined 75-day remapping procedure to assess durable PV 
isolation. In these patients, 91.3% of PVs remained isolated. All PVs in forty-nine 
(49) patients undergoing reassessment remained isolated. These results support the 
safety and performance of the system. 
1.3.3 
Endocardial Ablation Studies - The PEFCAT II Study 
FARAPULSE, Inc. has also initiated a safety and feasibility study at Na Homolce 
Hospital in Prague, Czech Republic and KBC Split in Split, Croatia, under the 
“PECAT II” Protocol, CS0571.This study is being conducted using the FARAPULSE 
Endocardial Alablation System, including both the FARAWAVE and FARAFLEX 
ablation catheters. Ten (10) patients were enrolled in October 2019. Five (5) patients 
were enrolled in Prague and five (5) were enrolled in Split. All patients were 
discharged in good condition. 
 
No patients experienced a serious adverse event during the study. 
 
At the conclusion of the index procedure, all pulmonary veins (PVs) in all patients 
were isolated using the FARAPULSE Endocardial Ablation System. Four (4) patients 
received successful ablation of the cavotricuspid isthmus with the FARAFLEX 
Ablation Catheter for associated atrial flutter during the index procedure. 
 
Nine (9) patients have returned for the protocol-defined 75-Day remapping procedure 
to assess durable PV isolation and durable cavotricuspid isthmus ablation, when 
applicable. In these patients 94.1% of PVs remained isolated. Two (2) out of three (3) 
patients that received cavotricuspid isthmus ablation at index and returned for their 
remapping procedure had durable cavotricuspid isthmus ablation. Six (6) out of nine 
(9%) patients that returned for a remapping procedure had durable PVI and

performance of the system. 
1.3.4 
Endocardial Ablation Studies – The PersAFOne Study 
FARAPULSE, Inc. has also initiated a safety and feasibility study at Na Homolce 
Hospital in Prague, Czech Republic and KBC Split in Split, Croatia, under the 
“PersAFOne” Protocol, CS0607. This study is being conducted using the 
FARAPULSE Endocardial Ablation System, including both the FARAWAVE and 
FARAFLEX Ablation Catheters, for the treatment of Persistent Atrial Fibrillation. 
Twenty-eight (28) patients were enrolled between October 2019 and July 2020. Sixteen 
(16) patients were enrolled in Prague and twelve (12) patients were enrolled in Split. 
All patients were discharged in good condition. 
 
One patient was hospitalized during follow up due to eye trauma and hospitalized again 
for a surgical operation to treat the eye trauma. One patient was hospitalized after they 
fell off of a roof. One patient was hospitalized for tonsillitis. One patient experienced a 
pericardial effusion after the protocol-defined remapping procedure, although no 
FARAPULSE devices were used during the remap procedure. All events have 
resolved. 
 
At the conclusion of the index procedure, all pulmonary veins (PVs) in all patients 
were isolated using the FARAPULSE Endocardial Ablation System. Thirteen (13) 
patients had successful ablation of their cavotricuspid isthmus for treatment of 
associated atrial flutter utilizing the FARAFLEX Ablation Catheter. Twenty-five (25) 
patients had successful ablation of the left atrial posterior wall performed with the 
FARAPULSE Endocardial Ablation System. Two (2) patients had successful mitral 
isthmus ablation with the FARAFLEX Ablation Catheter at the index procedure. 
 
Twenty-five (25) patients have returned for the protocol-defined 75-Day remapping 
procedure to assess the durability of the index lesion set. 87.6% of veins remapped 
remained isolated. 19/25 patients had all of their veins isolated at the remap procedure. 
9/12 patients that received ablation of the cavotricuspid isthmus had durable lesions at 
the remap. 18/22 patients that had left atrial posterior wall ablation performed at index 
had durable isolation at the remapping procedure. Both patients that had mitral isthmus 
ablation at the index procedure did not have durable lesions. These results support the 
safety and performance of the system. 
1.3.5

At the conclusion of the index procedure, all pulmonary veins in all patients were 
successfully ablated with the FARAPULSE Ablation System Plus. Prospective 
remapping was not required for this study. All fifteen (15) patients remain in follow up. 
 
1.4 
Rationale for Conducting This Feasibility Study 
Catheter ablation for PAF with a variety of energy sources and catheter configurations 
has been demonstrated to be a safe and effective procedure. The FARAPULSE Cardiac 
Ablation System Plus, with the exception of the FARAPOINT Pulsed Field Ablation 
Catheter which is currently undergoing preclinical testing, has undergone preclinical 
and clinical testing to demonstrate that it can isolate pulmonary veins and posterior left 
atrium quickly and with minimal complications, using a standard catheter-based 
endocardial procedure. Ongoing clinical follow-up demonstrates durable lesions at 75- 
90 day remapping procedures. 
This study will investigate the use of the the FARAPULSE Cardiac Ablation System 
Plus in the treatment of patients with PersAF. The availability of the FARAWAVE 
Ablation Catheter and the FARAPOINT Ablation Catheter allow the delivery of PEF 
ablation in the same locations as existing treatment such as RF ablation, and thus 
permit treatment of PersAF. The addition of the 8Fr focal FARAPOINT Ablation 
Catheter will provide flexible PEF lesion creation via a low-profile (8Fr diameter) form 
factor with maneuvering capabilities similar to those of widely marketed 8Fr RF 
ablation catheters. Enhanced maneuverability may make the creation of technically 
challenging lesion sets, such as those focal atrial triggers at the mitral isthmus or 
posterior wall, easier thus reducing procedure times and related complications. Further, 
both remap and long-term clinical follow-up data using existing approved devices for 
complex lesion sets in PersAF have shown mixed results24. The highly durable PEF 
lesions demonstrated to date in other FARAPULSE studies, especially for PVI, 
indicates that focal ablation using the same energy modality in the FARAPOINT 
catheter may improve these outcomes. 
Potential Risks: Based on the growing experience with the FARAPULSE Endocardial 
Ablation System, the risks associated with this small feasibility study are not expected 
to differ from those products that are approved and available on the market for catheter- 
based or surgical ablation procedures. In addition, verification and validation testing of 
the FARAPULSE Cardiac Ablation System Plus will ensure device safety and 
performance during the clinical investigation as well as compliance with the applicable 
parts of the Medical Device Directive 93/42/EEC. FARAPULSE will ensure through its 
Risk Management processes that the residual risks have been reduced to a level that is 
as low as possible. 
 
Potential Benefits: A study of up to 60 patients for assessment in this protocol will have 
the following potential benefits: 
• To provide treatment to subjects with PersAF using an investigational device 
which has demonstrated the ability to isolate pulmonary veins and the posterior

Catheter 
(Provided in 31mm and 35mm Deployed Diameters) 
 
The FARAWAVE Pulsed Field Ablation Catheter is a multi-electrode catheter that 
connects electrically to the FARASTAR Pulsed Field Ablation Generator. It consists 
of a multi-electrode ablation catheter with electrodes arranged on splines. The 
Ablation Catheter consists of a distal section with five splines that deploy into a 
basket-shaped configuration or flower-shaped configuration with five petals (Figure 
3), a shaft section, and a proximal handle with a manually operated deployment 
control. Each spline has a single electrode that is separately wired to facilitate 
connection to a mapping or recording system (this is an optional feature offered to the 
user). The handle includes a flush port for saline infusion, a deployment control knob 
with a guidewire lumen hub that can be connected to a hemostasis valve, and a cable 
with connectors. The FARAWAVE Catheter connects to the FARASTAR 
Connection Cable (included with the FARAWAVE Catheter) which connects to the 
FARASTAR Pulsed Field Ablatin Generator. The Pulsed Electric Field energy is 
delivered via the FARASTAR Pulsed Field Ablation Generator over the set of 
ablation catheter electrodes. The FARASTAR Connection Cable is single-use, sterile 
and provides the required length to connect to the FARASTAR Pulsed Field 
Ablation Generator. 
 
Additional details are provided in the IFU LBL1262 for the specific use and 
procedural steps of the FARAWAVE Pulsed Field Ablation Catheter.

FARAPOINT Pulsed Field Ablation Catheter 
The FARAPOINT Pulsed Field Ablation Catheter is a multi-electrode unidirectional, 
deflectable percutaneous catheter that connects to the FARASTAR Pulsed Field 
Ablation Generator and is designed to deliver PEF energy from the Pulsed Field 
Ablation Generator for cardiac tissue ablation. The FARAPOINT Pulsed Field 
Ablation Catheter is an adjunctive catheter designed to create smaller focal-type 
lesions for the following indications for use: 
• Gap ablation to complete electrical isolation of the pulmonary veins, 
• Focal ablation of cardiac arrhythmias, and 
• Creation of ablation line between the inferior vena cava and the tricuspid valve. 
 
The catheter consists of the following major sections: 1) a deflectable distal section 
with three electrodes, 2) an 8F catheter shaft, and 3) a proximal handle with a 
manually operated deflection control and a connector for attachment to the 
FARASTAR Generator (Figure 5).

The FARAPOINT Catheter is an 8F device with a uni-directional deflectable section 
length of 7.5cm and a usable length of 115cm measured from the catheter strain relief 
to the catheter tip when in the undeflected state. Two pairs of 2mm and 1.5mm length 
eelctrodes enable bipolar delivery of PFA energy. These electrodes attach to the 
FARASTAR generator through one FARASTAR Connection Cable. The 
FARAPOINT Catheter can be used with the FARADRIVE Steerable Sheath, the 
Abott Agilis 8.5Fr NxT Steerable Introducer, or the Boston Scientific Zurpaz 8.5Fr 
Steerable Sheath. 
 
Additional details are provided in the IFU LBL0840 for the specific use and 
procedural steps of the FARAPOINT Pulsed Field Ablation Catheter. 
 
 
2.4.3 
FARASTAR Pulsed Field Ablation Generator and Recording System Module 
The FARASTAR Pulsed Field Ablation Generator consists of the following 
components: FARASTAR Pulsed Field Ablation Generator, Recording System 
Module, EGM Input Module, ECG Output Module, and accessory cables for system 
connections. The Pulsed Field Ablation Generator System is designed to deliver Pulsed 
Electric Field (PEF) energy to endocardial sites in the heart via the FARAWAVE and 
FARAPOINT Pulsed Field Ablation Catheters and other compatible devices. Refer to 
IFU LBL1262, IFU LBL0565, and IFU0840 for the specific use and procedural steps of 
the Pulsed Field Ablation Catheters, respectively, IFU LBL1062 for the FARADRIVE 
Steerable Sheath and User Manual LBL1260 for the FARASTAR Pulsed Field 
Ablation Generator. 
 
The FARASTAR Pulsed Field Ablation Generator is a 12-channel output unit that 
generates a pulsed voltage waveform that can be delivered to the ablation catheter 
electrodes. The FARASTAR Generator currently allows ablation energy in discrete 
user-selectable voltage settings between 1800V and 2100V, depending on the catheter 
used. 
 
The FARASTAR Pulsed Field Ablation Generator may be used in either Asynchronous 
Mode or Synchronous Mode. Asynchronous Mode delivers therapy without regard to 
the intrinsic cardiac cycle, whereas Synchronous Mode includes pacing output from an 
internal stimulator integrated into the Generator which captures the heart in 
synchronization with the delivered therapeutic pulses.

The Recording System Module is an accessory component to the FARASTAR 
Generator. This component’s primary function is to disconnect the inputs of the EP 
Lab Recording System (non-FARAPULSE third party device) from being connected to 
the patient during Pulsed Field Ablation delivery. The inputs include diagnostic 
catheters and surface ECGs. This action reduces the risk of interference to the 
recording system inputs during an ablation. The Recording System Module resides 
between the patient and the EP Lab Recording System. Its functionality is implemented 
by a set of relays that are controlled automatically by the FARASTAR Generator. 
 
Details regarding use of the FARASTAR Generator and the Recording System Module 
are provided in the FARASTAR Pulsed Field Ablation Generator User Manual 
LBL1260 and the FARASTAR Recording System Module User Manual LBL1261 
respectively.

3.11 Procedures 
3.11.1 
Index Procedure 
The investigator will confirm that the following have been achieved: 
• For women of childbearing potential – a negative pregnancy test 
• Baseline NIHSS score 
• The patient is not on amiodarone 
FARAPULSE Pulsed Field Ablation procedure patients will undergo anesthesia 
according to institutional protocol. They will then be prepared in conventional sterile 
fashion for a cardiac catheterization procedure. Femoral vein access will be obtained 
via Seldinger technique. Transseptal access to the left atrium will then be obtained 
using either a FARADRIVE Steerable sheath or a commercially approved sheath and 
Brockenbrough needle. The transseptal sheath will then be withdrawn, leaving 
guidewire access to the left atrium. The FARADRIVE Steerable Sheath, or a 
commercial equivalent as described above inTable 2,will then be prepared and 
advanced via guidewire to the left atrium. Commercially approved multielectrode 
pacing catheters will then be placed via conventional technique at the investigator’s 
discretion. A baseline electrophysiological assessment of pulmonary vein connection 
to the left atrium will be made and documented via FARAWAVE or a commercially 
approved diagnostic catheter placedin each addressable pulmonary vein. A baseline 
3D electroanatomical map may also be made at the investigator’s discretion. The 
diagnostic catheter will then be removed from the FARADRIVE Steerable Sheath or 
commercial equivalent. 
The FARAWAVE Pulsed Field Ablation Catheter will then be prepared and 
advanced over the guidewire to the left atrium through the sheath. The guidewire will 
be advanced into a target pulmonary vein, the catheter splines will be deployed to suit 
target anatomy by retracting the deployment knob, and the deployed catheter will be 
advanced to the ostium of the target pulmonary vein. At the investigator’s discretion, 
contrast venography may be performed to verify placement of the catheter at the 
ostium. Cardiac pacing capture from the external cardiac stimulator will be obtained 
via connection to a diagnostic catheter. Once pacing capture is confirmed, ablation 
will be performed. Ablation dose will be selected at the investigator’s discretion in 
accordance with LBL0198, FARASTAR Generator User Manual. 
Ablation with the FARAWAVE Pulsed Field Ablation Catheter may be repeated at 
the same site or at another target site at the physician’s discretion using deployment 
configurations to suit target anatomy. Each addressable pulmonary vein will be 
ablated in turn beginning with placement of the guidewire, deployment of the ablation 
catheter, confirmation of pacing capture, and ablation. The effect of the ablation(s) 
may be checked post-procedure by pacing maneuvers, ECG recordings, 3D 
electroanatomic mapping, or by using the mapping electrodes on the ablation catheter 
splines. Ablation using the FARAPOINT Pulsed Field Ablation Catheter may be 
performed to close gaps in electrical isolation of pulmonary veins, focally ablate 
cardiac arrhythmias, or create a line of ablation at the cavo-tricuspid isthmus (CTI).

Blanking Period 
The Blanking Period consists of Day 0 (the date of Index Procedure) through and 
including Day 90. 
During the Blanking Period, any recurrence of AF will be documented; however, 
recurrences of AF, AFL or AT during this time will not be consideredTherapeutic 
Failures. 
Subjects may undergo one repeat ablation during the Blanking Period without 
creating a Therapeutic Failure, following the procedure detailed in the preceding 
sections. This may occur during the Remap Procedure or at another procedure as 
clinically indicated. 
If a second repeat ablation procedure is performed during this time, or any nonstudy 
device is used for cardiac ablation, the subjects will be considered a Therapeutic 
Failure but will remain in the study. 
Towards the end of the Blanking Period, any AFD treatment will be discontinued 
unless the Investigator deems the withdrawal of AFD treatment not to be in the best 
interests of the patient. 
3.11.4 
Arrhythmia Core Lab 
An Arrhythmia Core Lab will oversee the provision, collection and analysis of data 
from the Event Monitors and Holter Monitors specified in this protocol. 
• An Event Monitor will be provided at the 60-Day Remap to be used through the 
remainder of the 12-month follow-up interval for weekly scheduled and ad hoc 
symptomatic monitoring. Investigational sites will be provided with the Event 
Monitor and instructions for its use by the Arrhythmia Core Lab. The 
investigational sites will then provide the device and instructions for use to the 
subject. The Event Monitor will be returned to the Arrhythmia Core Lab at the 
time of the subject’s exit from the study. ECG data from the Event Monitor will 
be analyzed by the Arrhythmia Core Lab. 
• A 24-hour continuous ECG monitor will be provided at the 6 and 12-Month 
Visits. Investigational sites will be provided with the continuous ECG monitor

4. Benefit Risk Assessment 
The Sponsor has conducted an analysis of the benefits and risks of the 
FARAPULSE Cardiac Ablation System Plus and ablation procedure as described 
below. The conclusion of this review is that the subject investigation is justified 
because the overallpotential benefit to the population outweighs the risks. 
4.1

4.2 
Potential Risks 
As detailed in Section 1.4, Summary of FARAPULSE Clinical Studies, the risk 
profile associated with the FARAPULSE Cardiac Ablation System Plus and the 
ablation procedure is expected to be consistent with similar devices currently in 
clinical use for percutaneous cardiac ablation for treatment of persistent atrial 
fibrillation. 
The FARAPULSE Cardiac Ablation System Plus is a Pulsed Electric Field (PEF) 
ablation system that produces continuous transmural cardiac lesions to treat atrial 
fibrillation using an ablation procedure that is similar to other commercially 
available percutaneous ablation catheters. More specifically: 
• The device system is used during percutaneous endocardial ablation procedures 
like other commercially approved catheter systems. 
• The device system is composed of similar biocompatible materials. 
• The device system is a non-thermal ablation technology with targeted cardiac 
tissue specific mechanism of ablation. 
• The device uses the standard percutaneous techniques for ablation procedures. 
• The device utilizes a standard irreversible electroporation generator to deliver 
energy in the form of ablation dose. 
 
A fundamental difference between the FARAPULSE Cardiac Ablation System Plus 
and other commercially approved atrial fibrillation ablation systems is that the 
Pulsed Electric Field or irreversible electroporation energy is delivered through

electrodes embedded in the endocardial ablation catheter for delivery of such 
energy in the pulmonary veins. 
As such, the potential risks are roughly equivalent to those associated with 
commercially released systems being used for percutaneous cardiac ablation 
procedures. Currently, the complication rates for commercially available catheters 
are low and have declined as physicians have continued to learn more about cardiac 
ablation techniques. Furthermore, FARAPULSE, Inc. has conducted bench and in- 
vivo testing to ensure safe use of the device during clinical investigation and is in 
compliance with the applicable requirements of the Medical Device Directive 
93/42/EEC. 
4.3 
Potential Benefits 
There are no guaranteed benefits from participation in this study. Information 
gained from the conduct of this study may also be of benefit to other persons with 
the same medical condition. 
A study of up to 60 patients for assessment in this protocol will have the following 
potential benefits: 
• To provide treatment to subjects with PersAF using an investigational 
device which has demonstrated the ability to isolate pulmonary veins and 
reduce the subsequent occurrence of symptomatic atrial fibrillation in a 
small number of patients treated for PAF (see Section 1.4, Summary of 
FARAPULSE Clinical Studies); 
• To generate additional data demonstrating that the endocardial creation of 
electrically isolating lesions via Pulsed Electric Field (PEF) catheter ablation 
applied using the FARAPULSE Cardiac Ablation System Plus is a safe and 
potentially effective treatment for drug-resistant, recurrent, 
symptomaticpersistent atrial fibrillation (PersAF); 
• To assess the feasibility and safety of the FARAPOINT Pulsed Field 
Ablation Catheter for focal ablation in accordance with its proposed 
indication for use; 
• To assess the protocol elements and design for subsequent use in an 
expanded multi-center European CE Mark Trial.

5. Statistical Analysis and Reporting 
A Statistical Analysis Plan (SAP) will be prepared that governs the collection, 
analysis and reporting of the data from this investigation. This section summarizes 
the essential elements of that plan. 
5.1 
General Statistical Considerations 
All statistical analyses will be performed using validated statistical software. 
Continuous variables will be summarized using standard quantitative statistics: 
number of available observations, mean, standard deviation, median, quartiles and 
range (minimum and maximum observed values). The number of missing 
observations will also be specified. 
Categorical variables will be summarized using classical frequency statistics: 
number of available observations and percentages by categories. Percentages will 
be calculated on the number of available observations. The number of missing 
observations will also be specified. 
When applicable, bilateral asymptotic or exact confidence intervals for binomial 
distributions will be calculated at the 95% level. 
A full data listing will be prepared. Data will be pooled from all study sites. 
All related and resulting reports, documents and data will be produced and 
maintained in such a way as to ensure their control and the protection of subject 
privacy as far as is reasonably practicable. Data files and analytic reports will be 
archived according to requisite regulatory standards. 
5.2 
Control of Systematic Error and Bias 
Subjects are not randomized in this single arm study and therefore masking is not 
achievable. Error and bias are being controlled by several means, including a 
comprehensive set of study procedures as defined in the protocol to ensure 
consistent management and outcome measure assessment. Follow-up Holter 
monitoring and event monitoring data, and all MRI/CT dimensions of PVs, will be 
assessed objectively by third parties according to standard clinical protocols. 
Primary effectiveness and safety outcomes will be reviewed by an independent 
Clinical Events – Data Monitoring Committee (CEDMC). A complete Study 
Report will allow scientific and clinical reviewers to independently assess potential 
error and bias. 
Study outcomes will be reviewed and adjudicated by an independent Clinical 
Events and Data Monitoring Committee (CEDMC) more fully described in Section 
9.10, Clinical Events and Data Monitoring Committee. 
5.3 
Sample Size Justification 
This investigation is the next phase of ongoing feasibility studies to allow the 
controlled introduction of a new cardiac ablation catheter (FARAPOINT Pulsed 
Field Ablation Catheter). This is a feasibility study with no formal hypothesis 
testing and therefore no required sample size. Study results will be presented using

descriptive statistics. Results from this study will be used to inform and design 
additional clinical studies. 
Sixty (60) subjects at up to four sites will allow the assessment of the modified 
devices and the initial experience and training of investigators and study staff at a 
new investigational site. 
5.4 
Subject Disposition 
The disposition of all subjects enrolled in the study will be described in tables and 
diagrams, including numbers screened, treated and assessed at each scheduled 
follow-up interval. Subjects who do not complete the study will be enumerated and 
the reason(s) for their discontinuation will be described. 
5.5 
Imputation for Missing Data 
Imputations for missing data in (e.g., withdrawn subjects, loss to follow-up, missing 
data) will not be performed. Analyses will be performed with all available data 
only. 
5.6 
Populations for Analysis 
Enrolled Population: all subjects who provided their informed consent. 
Safety Subjects/Intent to Treat Subjects: all enrolled subjects except those who 
terminate their participation prior to the beginning of the Index Procedure. 
Per Protocol Subjects: Intent-to-treatsubjects for whom the Index Procedure is 
finished without interfering investigational device deficiency or malfunction. 
Reasons for exclusion from the populations will be given, and a summary of 
adverse events for these subjects, if any, will be provided. 
5.7 
Final Clinical Report 
A final clinical report including these analyseswill be prepared at the conclusion of 
the study or at such time as the study may be prematurely terminated. Copies of the 
final report will be provided to the investigator and their EC and to the CA as 
applicable.

Composite Safety Endpoint Definitions 
 
Adverse Event 
Description/Criteria 
Death 
Death 
Myocardial infarction (MI) 
Myocardial infarction will be demonstrated by any one of the 
following: 
1) detection of ECG changes indicative of new ischemia (new 
ST-T wave changes or new LBB) that persist for more than 1 
hour. 
2) development of new pathological Q waves on an ECG 
3) imaging evidence of new loss of viable myocardium or new 
regional wall motion abnormality 
Persistent diaphragmatic 
paralysis 
Diaphragmatic paralysis: Change from baseline diaphragmatic 
function as demonstrated radiographically by elevation of the 
diaphragm above the normal range but not due to a pulmonary 
process such as atelectasis. 
Permanent: not resolved by completion of study follow-up 
Stroke or transient ischemic 
attack (TIA) 
Stroke is an acute symptomatic episode of neurological 
dysfunction attributed to a vascular cause (ischemia or 
hemorrhage) in which symptoms last more than 24 hours, or if 
symptoms last less than 24 hours, a brain imaging study 
demonstrates infarction. 
Transient ischemic attack is a new focal neurological deficit 
with rapid symptom resolution always within 24 hours.

Adverse Event 
Description/Criteria 
Peripheral or organ 
thromboembolism 
Formation in a blood vessel of a clot (thrombus) that results 
from the breaking loose of all or part of an existing thrombus, 
which is then carried by the blood to lodge in/occlude a more 
distal vascular site. 
Pericarditis 
Inflammation of the pericardial space that results in an effusion 
that leads to hemodynamic compromise or required 
pericardiocentesis, prolongs hospitalization by more than 48 
hours, requires hospitalization, or persists for more than 30 days 
following the ablation procedure. 
Cardiac 
tamponade/perforation 
The development of a significant pericardial effusion during or 
within 30 days of undergoing the index AF ablation procedure. 
A significant pericardial effusion is one which results in 
hemodynamic compromised (<80mmHg systolic bp), requires 
elective or urgent pericardiocentesis, or results in a 1cm or more 
pericardial effusion as documented by echocardiography. 
Vascular access 
complications requiring 
intervention 
Vascular access complication (e.g. groin hematoma, AV fistula, 
pseudoaneurysm) requiring intervention (e.g. surgical repair, 
blood transfusion). 
Heart block 
Impairment of AV conduction requiring permanent pacing 
intervention, if resulting from inappropriate ablation application. 
Pulmonary vein (PV) 
stenosis 
>70% diameter reduction of pulmonary vein from baseline 
CT/MRA scan. 
Atrio-esophageal fistula 
Connection between the atrium and the lumen of the esophagus 
as evidenced by documentation of esophageal erosion combined 
with evidence of a fistulous connection to the atrium.

7.7 
Causality Relationship (definitions from MDCG 2020-10/1) 
The investigator will assess the causality of all adverse events in relation to the 
investigational device or any other study-related procedures according to four 
different levels of causality: 
1) Not related: relationship to the device, comparator or procedures can be excluded 
when: 
- 
the event has no temporal relationship with the use of the investigational 
device or the procedures related to application of the investigational device ; 
- 
the serious advserse event does not follow a known response pattern to the 
medical device (if the response pattern is previously known) and is 
biologically implausible; 
- 
the discontinuation of medical device application or the reduction of the 
level of activation/exposure - when clinically feasible – and reintroduction 
of its use (or increase of the level of activation/exposure), do not impact on 
the serious event; 
- 
the event involves a body-site or an organ not expected to be affected by the 
device or procedure; 
- 
the serious event can be attributed to another cause (e.g. an underlying or 
concurrent illness/ clinical condition, an effect of another device, drug, 
treatment or other risk factors); 
- 
the event does not depend on a false result given by the investigational 
device used for diagnosis, when applicable; 
In order to establish the non-relatedness, not all the criteria listed above might be 
met at the same time, depending on the type of device/procedures and the serious 
event. 
 
3) Possible: the relationship with the use of the investigational device or 
comparator, or the relationship with procedure is weak but cannot be ruled out 
completely. Alternative causes are also possible (e.g. an underlying or concurrent 
illness/ clinical condition or/and an effect of another device, drug or treatment). 
Cases were relatedness cannot be assessed or no information has been obtained 
should also be classified as possible.

4) Probable: the relationship with the use of the investigational device or 
comparator, or the relationship with procedures, seems relevant and/or the event 
cannot reasonably have explained by another cause. 
5) Causal relationship: the serious event is associated with the investigational 
device, comparator or or with procedures beyond reasonable doubt when: 
- 
the event is a known side effect of the product category the device belongs 
to or of similar devices and procedures; 
- 
the event has a temporal relationship with investigational device 
use/application or procedures; 
- 
the event involves a body-site or organ that 
▪ 
the investigational device or procedures are applied to; 
▪ 
the investigational device or procedures have an effect on; 
- 
the serious adverse event follows a known response pattern to the medical 
device (if the response pattern is previously known); 
- 
the discontinuation of medical device application (or reduction of the level 
of activation/exposure) and reintroduction of its use (or increase of the level 
of activation/exposure), impact on the serious event (when clinically 
feasible); 
- 
other possible causes (e.g. an underlying or concurrent illness/ clinical 
condition or/and an effect of another device, drug or treatment) have been 
adequately ruled out; 
- 
harm to the subject is due to error in use; 
In order to establish the relatedness, not all the criteria listed above might be met 
at the same time, depending on the type of device/procedures and the serious event.

CRF Instructions, and study procedures; communicate regularly with site personnel 
via mail, email, telephone, and/or fax; and make periodic monitoring visits to the 
site. During those visits, the Sponsor or its representatives will monitor the subject 
data recorded in the CRFs against the source documents at the site for all enrolled 
subjects. 
9.10 Clinical Events and Data Monitoring Committee 
The Sponsor has established an external group of expert physicians who are not 
investigators to serve as the Clinical Events and Data Monitoring Committee 
(CEDMC). This group will consist of a panel of 3 experienced, independent 
physicians who are not investigators and who will be supported by the Medical 
Monitor and Study Statistician. A combined CEDMC procedure is an appropriate 
structure for a 60 subject feasibility study. 
The CEDMC will review and approve a Charter. The CEDMC will convene during 
the study to screen, classify and adjudicate all adverse events reported in the subject 
investigation as well as major study outcomes.The CEDMC will be provided with 
case summaries,relevant source documents and any other information required to 
evaluate and adjudicate the adverse events and study outcomes. 
The CEDMC will alsoconvene to review safety data and trends during the conduct 
of the study. This formal assessment will occurat a minimumafter the enrollment of 
20 and then 60 subjects. The CEDMC will recommend to the Sponsor whether a 
study pause or termination is required if it identifies a trend that indicates a danger 
to patient safety. 
9.11 Data Management 
Data management procedures will be included in the Study Management Plan. 
CRFs will be made available to the participating site. Investigators are responsible 
for the accurate completion of patient CRFs during the study. The Investigator will 
ensure that complete, accurate and timely data on CRFs are completed, that 
protocol requirements are followed and that complications, adverse events and 
adverse device effects are correctly reported and investigated, as appropriate. The 
Investigator is expected to maintain all source documents as required by the CIP, 
including laboratory results, supporting medical records, and signed ICFs. The 
source documents will be used during the regular monitoring visits to verify 
information from the database against data contained on the completed CRFs. 
After CRF Monitoring has been complete and deficiencies / discrepancies resolved, 
CRFs will be provided to the Sponsor or CRO, and data from the study will be 
entered from the CRFs into a central database. CRF data will be reviewed to 
identify any inconsistent or missing data and any adverse events. Any data issues 
are to be promptly addressed with the Investigator by the CRO. 
9.12 Study Suspension or Early Termination 
The study can be discontinuedat any siteat the discretion of the Investigator or study 
Sponsor for reasons including, but not limited to, the following:

inform the clinical investigator/ investigational center of the termination or 
suspension and the reason(s) for discontinuation / suspension. The national and 
local regulatory authorities shall also be informed promptly and provided with the 
reason(s) for the termination or suspension by the Sponsor, CRO or by the clinical 
investigator/ investigation center. Further, if the study is discontinued or suspended 
prematurely, patients enrolled to that point will continue to be followed for safety 
through the 12-month timepoint. 
9.13 Criteria for Suspending/ Terminating a Study Center 
Sponsor reserves the right to stop the screening of subjects at the study center at any 
time after the study initiation visit if no subjects have been enrolled or if the center 
has multiple or severe protocol violations without justification or fails to follow 
remedial actions. 
Possible reasons for suspending/ terminating the study center include, but are not 
limited to: 
• Repeated failure to complete CRFsprior to scheduled monitoring visits; 
• Failure to obtain written informed consent using the EC-approved ICF; 
• Failure to report SAEs/ USADEs to Sponsor within 24 hours of knowledge; 
• Loss of (or unaccounted for) investigational product inventory or repeated failure 
of device accountability. 
9.14 Deviations from the Clinical Investigation Plan
