Late-breaking HRX data advance Field Medical's "instantaneous ablation" workflow and expand the clinical evidence for high-voltage focal PFA with the FieldForce™ PFA System
ATLANTA and CARLSBAD, Calif., Sept. 20, 2026 /PRNewswire/ -- Field Medical, Inc., advancing high-voltage focal pulsed field ablation (PFA) for complex arrhythmias, today announced publication of 12-month results from the first-in-human Field PULSE trial in JACC: Clinical Electrophysiology. The findings were presented simultaneously as a Late-Breaking Clinical Trial at HRX Live 2026.
Field Medical developed the FieldForce™ PFA System around a high-voltage focal PFA architecture designed first for the ventricle, where depth, stability and control are among the most difficult challenges in ablation. Field PULSE extends that work into the atrium and evaluates a subsecond point-by-point workflow Field Medical terms "instantaneous ablation." In this study, the approach was associated with procedural efficiency, durable pulmonary vein isolation (PVI) and flexibility beyond the pulmonary veins, without the need for prolonged catheter stability.
Key Findings:
- Procedural efficiency with subsecond focal PFA: 13-minute median elapsed PVI ablation time, with a fastest time of 7.7 minutes
- Durable PVI with the optimized waveform: 94.2% per-vein durability reflecting progressive improvement with waveform evolution
- Flexible focal ablation: 49% of patients received non-PV ablation for additional atrial targets
- No primary safety events were observed
- 80% freedom from atrial arrhythmias at 12 months with the optimized waveform
"Field PULSE demonstrates the feasibility of truly instantaneous focal PFA," said Vivek Reddy, M.D., co-principal investigator, lead author and electrophysiologist at Mount Sinai Health System. "Delivering the full application in less than 200 milliseconds reduces the need for prolonged catheter stability while preserving the flexibility of point-by-point ablation. The procedural efficiency, safety and pulmonary vein durability observed with the optimized waveform support continued clinical development of this approach."
The publication builds on Field Medical's peer-reviewed clinical work in ventricular tachycardia. Six-month outcomes from the company's first-in-human VCAS trial were published in Circulation in 2025. Field PULSE now adds first-in-human, peer-reviewed atrial data evaluating the same high-voltage focal PFA architecture through a distinct focal workflow in a different cardiac substrate.
"We designed FieldForce to solve some of the hardest problems in focal cardiac ablation, beginning in the ventricle," said Mark A. Turco, M.D., president and chief executive officer of Field Medical. "Field PULSE demonstrates that the same high-voltage focal PFA architecture can support an 'instantaneous ablation' workflow in the atrium. This growing body of evidence reinforces the range of the platform: depth and focal control in the ventricle, speed and precision in the atrium, and the versatility to address very different cardiac substrates through a familiar point-by-point approach. These results add important clinical evidence as we continue to advance our differentiated PFA platform."
The study, "High-Voltage Focal PFA Catheter for 'Instant' Point-By-Point Ablation: The First-In-Human FIELD-PULSE Trial to Treat AF," was published online in JACC: Clinical Electrophysiology concurrent with the HRX presentation. DOI: 10.1016/j.jacep.2026.09.001.

Three Ways to Keep Students Asking
AiR NOVA is designed for K-12 students and integrates three core AI functions into a single app:
- Tutor answers questions with verified sources. For instance, if a student asks, "Are new dinosaurs still being discovered?" Tutor explains at their grade level how the Doolysaurus was named in 2026 as Korea's third new dinosaur species, and then displays the reference article.
- Socrates is a patent-pending Socratic-dialogue mode that replies with guiding questions instead of direct answers, encouraging students to reason their way to an explanation in their own words. Students can also upload their inquiry reports, prompting Socrates to ask questions that walk them back through their conclusion process.
- Coach sustains the inquiry process beyond the initial answer. Students work through missions tied to specific articles, which involve predicting, asking questions, checking sources, explaining and reflecting.
In the Classroom
Teachers can utilize Coach to structure lessons around articles that match their curriculum, build worksheets and missions, and track each student's participation and results via comprehensive reports. This significantly reduces the time required to prepare inquiry-based lessons.
At launch, AiR NOVA's science and math content will align with South Korea's national curriculum, the U.S. Next Generation Science Standards (NGSS), the Common Core State Standards for Mathematics (CCSSM), Cambridge International and the International Baccalaureate (IB). AiR NOVA will be available in January 2027 on web, iOS and Android platforms, requiring no dedicated device. Pricing details will be announced at a later date.
