AtriCure Announces the First Patients Treated with Novel Dual Energy Platform

Key Terms

pulsed field ablation medical

Pulsed field ablation is a heart procedure that uses very short, high-voltage electrical pulses to selectively disrupt abnormal heart tissue that causes irregular rhythms, rather than heating or freezing it. For investors, it matters because this approach can shorten procedure times, reduce damage to nearby structures, and potentially lower complication rates compared with traditional thermal methods, which can affect device adoption, hospital costs, and market demand for treatment tools.

advanced radiofrequency ablation medical

Advanced radiofrequency ablation is a minimally invasive medical procedure that uses controlled radiofrequency energy—like a tiny, precise heat knife—to destroy or remove unwanted tissue such as tumors or malfunctioning heart tissue. Investors care because it represents a growing market for specialized devices, software and disposable tools, and improvements in precision, recovery time and reimbursement can drive higher adoption, sales and recurring revenue for medical device companies.

atrial fibrillation medical

Atrial fibrillation is a common heart rhythm problem in which the heart’s upper chambers quiver instead of delivering steady, strong pumps, like a washing machine on an unbalanced cycle. It matters to investors because it increases use of medications, medical devices, hospital care and long‑term monitoring, drives demand for new treatments and diagnostics, and can affect healthcare costs, regulatory decisions and revenue prospects across drug, device and insurance markets.

left atrial appendage medical

The left atrial appendage is a small, pouch-like outcrop on the left upper chamber of the heart that can trap blood clots, especially when the heart beats irregularly. For investors, it matters because treatments that close, remove, or influence clot formation in this pouch — either with devices, procedures, or drugs — can drive demand, regulatory review, reimbursement decisions, and clinical trial outcomes tied to related medical products and services.

transmural ablation medical

Transmural ablation is a medical procedure that destroys tissue across the entire thickness of a heart wall to block abnormal electrical signals that cause arrhythmias. Investors should care because achieving a full-thickness lesion is tied to how well treatments work and the risk profile of devices or therapies—like ensuring a cut goes all the way through a loaf to stop a leak—so it affects procedure success rates, regulatory approval, and market adoption.

pulmonary veins medical

Pulmonary veins are the vessels that carry oxygen-rich blood from the lungs back into the heart so it can be pumped to the rest of the body. Investors watch them because diseases, procedures, or devices affecting these veins can drive clinical trial results, regulatory approvals, treatment costs, and market demand for medical products—think of them as the return pipes from a filter to a pump: if they fail or are altered, the whole system is impacted.

left atrial posterior wall medical

The left atrial posterior wall is the back portion of the left upper chamber of the heart, a specific area where the heart’s electrical signals and blood flow meet. Investors care because this small region is often targeted by treatments, devices, and clinical trials for irregular heart rhythms; success or setbacks in therapies focused here can affect regulatory approvals, market demand, and a company’s financial prospects, much like a critical junction in a utility grid.

radiofrequency ablation medical

A medical procedure that uses a thin probe to deliver controlled heat (radiofrequency energy) to destroy or disable problematic tissue, such as small tumors, overactive nerves, or abnormal heart pathways; think of it as applying a focused heat spot to stop a problem without large incisions. Investors care because the technique drives demand for specialized devices, affects treatment volumes, reimbursement rates, and regulatory approvals, all of which influence medical-device and healthcare company revenues.

New technology combines Pulsed Field Ablation (PFA) and Advanced Radiofrequency Ablation with AtriCure’s EnCompass^® clamp to reduce treatment time for surgical ablation patients

MASON, Ohio--(BUSINESS WIRE)-- AtriCure, Inc. (Nasdaq: ATRC), a leading innovator in surgical treatments and therapies for atrial fibrillation (Afib), left atrial appendage (LAA) management and post-operative pain management, today announced successful first-in-human treatments using its novel dual energy platform that integrates Pulsed Field Ablation (PFA) with Advanced Radiofrequency Ablation (Advanced RFA). The procedures were performed by Dr. Adrian Pick in collaboration with the site Principal Investigator Professor Jayme Bennetts, at Victorian Heart Hospital in Australia under approval from the Monash Health Human Research Ethics Committee (HREC).

The new platform delivers the benefits of both technologies—combining the proven safety and effectiveness of radiofrequency (RF) ablation with the efficiency of PFA. Advanced RFA reduces ablation time significantly, while PFA enables transmural ablation in seconds. In the first two patients treated, total procedural ablation time to create a box lesion simultaneously isolating the pulmonary veins and the left atrial posterior wall was less than 60 seconds. Each ablation was also tested to prove acute electrical isolation.

“For 25 years, we’ve been the leader in cardiac surgical ablation,” said Michael Carrel, President and CEO of AtriCure. “Our innovative EnCompass clamp technology was a significant step in streamlining cardiac surgery ablation procedures. Now, building on the proven performance of our EnCompass clamp, this platform offers the best of both worlds. By pairing Advanced RFA with PFA, we’re delivering unprecedented speed and flexibility for surgeons.”

The AtriCure Isolator^® Synergy™ ablation system has a long history of safety and clinical effectiveness, supported by extensive published data, including over 100 publications, and has been used to treat over 450,000 patients in the last 20 years. AtriCure began development of the dual energy platform with the goals of shortening RF ablation times and introducing PFA as a complementary energy source. The system allows surgeons to use either modality independently or in combination.

“This technology builds on AtriCure’s strong legacy in cardiac surgical ablation,” said Dr. Pick. “Reduced procedure times and trusted devices mean more patients can benefit, and combining the benefits of RF with PFA should further ensure durable results.”

The Advanced RFA and PFA technologies are not yet approved for use in any market. AtriCure expects to initiate a clinical trial in the coming year, marking a key milestone in its product development pipeline.
