Overview

We are a novel ablation company committed to health innovation using our patented Nano-pulse Stimulation (“NPS”) technology, a revolutionary energy modality that delivers nanosecond-duration pulses of electrical energy, each less than a millionth of a second long, to nonthermally clear or kill targeted cells. NPS technology, also referred to as Nanosecond Pulsed-Field Ablation (“nsPFA”) technology when used to ablate cellular tissue, can be used to treat a variety of medical conditions for which an optimal solution remains unfulfilled. We developed our proprietary nPulse System (formerly known as CellFX), a novel nsPFA delivery platform, and commercialized the initial application of its nsPFA technology to treat benign lesions of the skin and in parallel, designed a variety of applicators, or disposables, to explore the potential use of the nPulse platform in other medical specialties. Based on our preclinical experience and the potential to significantly improve outcomes for patients in a large and growing market, we decided to focus our primary efforts on the use of nsPFA energy and the nPulse platform in the treatment of atrial fibrillation (“AF”), where approximately 1.9 million patients in the United States are diagnosed annually. This potentially represents a greater than $3.0 billion addressable market within electrophysiology alone combined with long-term double-digit growth. Additionally, we are also pursuing the treatment of atrial fibrillation via a surgical approach as well as select other markets where nsPFA technology could have a profound positive impact on healthcare for both patients and providers, such as surgical soft tissue ablation.

In March 2026, we announced a strategic realignment (“the 2026 Realignment”) to prioritize and accelerate the development of our nsPFA electrophysiology catheters and other cardiac devices for the treatment of AF. This initiative followed the release of our positive clinical data in February 2026 from our first in human feasibility study of our proprietary nPulse Cardiac Catheter System in patients with paroxysmal AF. In connection with the 2026 Realignment, we adjusted our capital allocation to prioritize the electrophysiology market development program and will reduce short term market development investments in cardiac surgery and reduce investments in sales and marketing for the Vybrance Percutaneous Electrode System to focus on additional market development, including generating clinical data for both expanded reimbursement coverage and regulatory label claims.

Our Cardiac Program

Atrial fibrillation is a type of heart arrythmia, or irregular heartbeat, caused by faulty electrical signals in the heart. AF is a highly prevalent condition and is growing significantly with an ageing population. It is estimated that 43 million people worldwide are affected by AF. Treatment requires the precise and safe ablation of heart tissue to block or otherwise prevent these faulty electrical signals from causing the irregular heartbeat, and we believe nsPFA energy is uniquely suited to perform an integral role in the treatment of AF and that it will prove to be highly differentiated from other energy modalities in use today.

The results of preclinical and clinical testing of our most advanced nPulse cardiac products, namely our endocardial ablation catheter and surgical ablation clamp, have exceeded our expectations and initial data have been presented at physician and industry conferences. While these devices serve different physicians, the application of nsPFA energy to safely and effectively ablate cardiac tissue to treat AF are the same, and we believe there will be important synergies realized through their contemporaneous development. The Company’s cardiac endocardial ablation catheter and cardiac surgical ablation clamp both generate our proprietary nsPFA pulses of electrical energy. Recently, we initiated pivotal studies to test both these devices for the treatment of AF and we discuss each of these clinical-stage products in more detail below.

nPulse Cardiac Catheter System

Our nPulse Cardiac Catheter System is uniquely designed to provide a circumferential, or circular, ablation in a single treatment cycle. We believe this will enable faster treatment times compared to what is currently performed with thermal modalities, especially when ablating around the pulmonary veins, a common treatment approach for AF.

In recent years, Pulsed Field Ablation (“PFA”) has gained attention in electrophysiology for the treatment of AF because of its safety profile and speed. However, current clinical products employing PFA in AF treatment differ from nsPFA technology in that the pulse widths are longer, typically in the microsecond domain. We believe nsPFA technology, which delivers pulses of electrical energy that are each less than a millionth of a second long, can offer similar safety advantages as PFA and may provide improved efficacy advantages based on the circumferential design of our catheter and because it appears nsPFA technology can create deeper ablations. We believe these advantages will be important to electrophysiologists, so we are working with leaders in the field to develop this technology quickly.

Our proprietary catheter has been in development for several years and we have been working with leaders in the electrophysiology field to test the catheter in preclinical studies. After seeing encouraging preclinical results, in December 2023, we initiated a first-in-human clinical study in Prague, Czech Republic, to test our nPulse Cardiac Catheter System in patients with AF and both the acute data and initial remapping data from this study were compelling. We therefore expanded the initial clinical protocol in 2024 to include participation by two additional sites, including a clinical site in Rome, Italy, with Dr. Andrea Natale M.D., F.A.C.C., F.H.R.S., F.E.S.C., a world recognized leader in the electrophysiology field and the current Executive Director at the Texas Cardiac Arrhythmia Institute. To date, seven clinical investigators at these European sites, including Dr. Natale and Dr. Vivek Reddy, Director of Cardiac Arrhythmia Services at the Mount Sinai Fuster Heart Hospital in New York, have enrolled and treated more than 175 patients in this first-in-human study. In February 2026, at the AF Symposium, Dr. Reddy presented 6- and 12-month follow up data for the first 150 patients from this study. These data show 96% procedural success of evaluable patients at one year as well as early indications of the disruptive market potential for our nPulse catheter, such as total procedure times in the study of approximately 65 minutes per patient. This long-term data was further reinforced at the 2026 Heart Rhythm meeting with data from a total of 177 patients. The 5 second Cohort (n=141) showed 96.2% procedural success by 24-hour holter at one year in addition to 90% Kaplan-Meier estimated freedom from all atrial arrhythmias at one year.

Given the compelling data seen in the first-in-human study of our nPulse Cardiac Catheter, in 2025 we submitted an Investigational Device Exemption (IDE) application for review by the FDA to conduct a single-arm, multicenter, prospective study designed to demonstrate primary safety and effectiveness of the nsPFA Cardiac Catheter System for the treatment of recurrent drug-resistant symptomatic paroxysmal AF. In December 2025, the FDA approved our IDE submission, and the first patients were treated in April 2026 at St. Bernards Medical Center in Jonesboro, Arkansas, under the leadership of Devi Nair, MD, Principal Investigator of the Arrhythmia Research Group. This IDE study is expected to enroll at least 164 evaluable pivotal patients at up to 30 sites, including sites outside the United States, and has enrolled more than half of its evaluable patients to date. We continue to believe we will need PMA approval from the FDA to market and sell our catheter with an AF indication in the United States. Upon PMA approval, we would expect to commercialize the nPulse Cardiac Catheter Sys

nPulse Vybrance Percutaneous Electrode System

Our first product for soft tissue ablation in a surgical setting, the Vybrance Percutaneous Electrode System, consists of a disposable, percutaneous, needle electrode for use with our proprietary nPulse Console. This novel electrode is designed to harness and deliver the key advantages of nsPFA energy, enabling precise nonthermal removal of cellular tissue without inducing thermal necrosis.

After years of preclinical development and testing, in June 2023, we initiated a first-in-human study using our proprietary nsPFA-enabled percutaneous electrode. This study was conducted by Professor Stefano Spiezia at the Ospedale del Mare in Naples, Italy, to help us better understand and confirm the mechanism of action and tissue response of nsPFA energy in internal organs such as the thyroid. Thirty study subjects were treated, all of whom tolerated the procedure well with no reported serious side effects. Ultrasound images post procedure showed treated portions of the benign thyroid nodules were mostly resorbed with no sign of scarring or fibrosis, which can be a side effect of other ablation modalities using thermal energies.

In parallel, in November 2023, we filed a premarket notification 510(k) with the FDA for clearance to commercialize our novel Vybrance Percutaneous Electrode System in the United States. In March 2024, we received FDA 510(k) clearance for our Vybrance Percutaneous Electrode System for use in the ablation of soft tissue in percutaneous and intraoperative surgical procedures. More recently, in August 2024, we received FDA 510(k) clearance for a second size of the percutaneous electrode needle, which we believe will provide our customers with an additional treatment option for their patients.

Since securing 510(k) clearance to market and sell the Vybrance Percutaneous Electrode System in the United States, we have engaged with experts in the field of soft tissue ablation to gather information to help shape our commercial endeavors (our “Pilot Program”). To date, we have placed our nPulse System at sites in the United States under either short-term evaluation, consulting or other early commercial agreements pursuant to which the sites have been performing initial patient treatments and evaluating the nPulse System as well as providing valuable feedback and support for our first launch of an nsPFA-enabled surgical product.

More recently, in September 2025, we commenced a clinical trial (PRECISE BTN) to generate clinical evidence to demonstrate the safety and effectiveness of this less-invasive thyroid-preserving procedure and support commercialization of the Vybrance Percutaneous Electrode System in the United States. In this study, benign thyroid nodule soft tissue ablation procedures will be performed on up to 50 patients at up to four sites. Study endpoints evaluated during the follow-up timepoints will include safety, targeted nodule volume reduction, symptom reduction, and improvements in quality of life and cosmesis over various follow-up periods. The pace of enrollment is encouraging and we expect enrollment to complete in the next few months. To date, these clinicians, together with those in the Pilot Program as well as our first commercial accounts, have completed more than 300 patient procedures. We expect to pursue more clinical evidenced-based milestones in connection with the limited market release of our percutaneous electrodes.

Our Cardiac Surgical Program

Atrial fibrillation (“AF”) is a type of heart arrythmia, or irregular heartbeat, caused by faulty electrical signals in the heart. AF is a highly prevalent condition and is growing significantly with an ageing population. It is estimated that 43 million people worldwide are affected by AF. Treatment requires the precise and safe ablation of heart tissue to block or otherwise prevent these faulty electrical signals from causing the irregular heartbeat, and we believe nsPFA energy is uniquely suited to perform an integral role for this application and that it will prove to be highly differentiated from other energy modalities in use today.

The Company’s cardiac surgical ablation clamp and cardiac endocardial ablation catheter both generate our proprietary nsPFA pulses of electrical energy. We discuss each of these products under development in more detail below.

nPulse Cardiac Surgical Clamp

Our surgical cardiac ablation clamp is designed for use by cardiac surgeons during the surgical treatment of AF. The standard of care surgical procedure for the treatment of AF is performed by cardiac surgeons and called the Cox-Maze procedure. The Cox-Maze procedure typically uses thermal ablation technologies, such as heat with radiofrequency ablation or cold with cryoablation, to create specific ablation lines in the heart muscle. These ablation lines block the conduction of electrical impulses and can cure patients of their AF.

We believe our nsPFA energy can provide important advantages over today’s thermal modalities in creating these ablation lines. For example, surgeons using the nPulse System should be able to deliver faster ablations and through thicker tissue than thermal modalities because of the nonthermal mechanism of action that nsPFA employs, which is not affected by heatsinks such as blood in the heart. In preclinical and clinical studies, our nsPFA Cardiac Clamp has consistently achieved transmural ablations in less than three seconds, independent of tissue type or thickness. Moreover, thermal modalities can cause char formation on electrode surfaces which can ca
