Demonstrating Instantaneous Ablation Through High-Voltage Waveforms and Efficient Point-by-Point Pulsed Field Ablation
CARDIFF-BY-THE-SEA, Calif., Feb. 6, 2026 /PRNewswire/ -- Field Medical, Inc., a clinical-stage medical technology company advancing pulsed field ablation (PFA) solutions for complex cardiac arrhythmias, today announced the presentation of late breaking clinical trial data from the first-in-human Field PULSE study at the 31st Annual International AF Symposium 2026, held February 5–7 in Boston.
Field PULSE evaluates a novel high-voltage, sub-second pulsed field waveform delivered through Field Medical's FieldForce™ Ablation System and Catheter, a focal, contact-sensing catheter, enabling instantaneous ablation through point-by-point energy delivery without reliance on prolonged tissue-catheter contact. The study was selected for a Late Breaking Clinical Trial (LBCT) presentation.
"By eliminating the need for sustained tissue-catheter contact, sub-second pulsed field delivery enables both efficient point-by-point ablation and individualized lesion sets," said Vivek Y. Reddy, M.D., principal investigator of Field PULSE and electrophysiologist at Mount Sinai, New York. "This approach preserves the flexibility physicians expect from focal ablation while delivering the procedural efficiency associated with pulsed field technologies."
Study Highlights
- Instantaneous energy delivery: Lesions created in less than 200 milliseconds, enabling rapid point-by-point ablation
- Procedural efficiency: Median bilateral pulmonary vein isolation (PVI) time of 12.5 minutes, with the fastest case completed in 7.7 minutes
- PVI durability: Remapping demonstrated progressive improvement in PVI durability with the optimized waveform
- By vein: 94.2%
- By patient: 84.6%
- Safety outcomes:
- No device-related serious adverse events
- No acute kidney injury, reported phrenic nerve palsy or clinically relevant hemolysis
- Among patients evaluated by brain MRI (n=14), no silent cerebral lesions (DWI+/FLAIR+) were observed
These findings extend Field Medical's body of clinical evidence of its high-voltage focal PFA approach beyond ventricular arrhythmias and into the development of therapy for atrial fibrillation (AF). Together with previously reported six-month first-in-human ventricular tachycardia (VT) data, the results support the emergence of a versatile ablation platform for all chambers of the heart, designed to enable focal PFA across atrial and ventricular substrates while preserving procedural efficiency.
"The Field PULSE results reinforce our approach of deliberately architecting focal PFA to address the fundamental limitations of existing methods, then validating its application through data," said Steven Mickelsen, M.D., founder and chief technology officer of Field Medical. "By delivering each ablation point in a fraction of a second, we reduce dependence on prolonged catheter stability, limit the impact of cardiac motion and establish a platform approach for treating complex arrhythmias."
The Field PULSE data were presented during the Late Breaking Clinical Trials Session I at AF Symposium 2026. Field Medical will be featured on Friday, February 6, from 7:30–8:30 a.m. during a scientific session on the biophysics of PFA for AF, including a presentation titled Maximizing Lesion Depth Using High Voltage PFA Waveform by Kenneth Ellenbogen, M.D., and during Case Transmission Session 6 on Saturday, February 7, from 7:30–9:30 a.m., highlighting AF Ablation Using a High-Voltage Field Medical PFA Catheter, presented by Vivek Reddy, M.D., using the FieldForce Ablation System and FieldForce Ablation Catheter.

Announced alongside M Series Smart Assist Module launch on Kickstarter
NEW YORK, April 4, 2026 /PRNewswire/ -- Yarbo, a company focused on intelligent yard robotics, today announced the Yarbo Open Platform, a long-term initiative currently under development and planned for release in early 2027. Designed to expand Yarbo's modular yard robot system across both software and hardware, the platform is intended to support deeper customization, broader smart home connectivity, and new forms of user and developer-driven functionality over time. The announcement coincides with the launch of the Smart Assist Module (SAM) for the M Series on Kickstarter.
The Open Platform is not available today. Instead, it reflects Yarbo's roadmap for how its ecosystem may evolve over time, including a three-layer software architecture built around an Open API, SDK, and no-code Automation Editor, as well as a hardware expansion framework designed to support future user-built and developer-built modules.
A Structured Approach to Software Integration and Automation
The Yarbo Open Platform is structured to accommodate different levels of technical expertise, from everyday users to experienced developers. It is designed to provide multiple entry points into the Yarbo ecosystem, enabling both software-driven automation and hardware-level expansion.
On the software side, the platform consists of three layers:
- Yarbo Open API — intended to enable connectivity between Yarbo devices and external platforms, allowing them to participate in broader home automation scenarios.
- Yarbo SDK — a set of development tools, including code libraries and documentation, designed for developers building custom features or integrations.
- Yarbo Automation Editor — a visual, drag-and-drop interface within the Yarbo app that allows users to create automation workflows without writing code.
Together, these components are intended to make automation accessible to a wide range of users, while also supporting more advanced development use cases.
The platform is also designed to support compatibility with widely used smart home ecosystems, including Home Assistant, Google Home, and Amazon Alexa, enabling users to incorporate Yarbo into existing connected home setups.
Extending Capability Through Hardware
In addition to software capabilities, the Open Platform introduces a hardware expansion approach designed to extend Yarbo's functionality beyond its existing modules.
At the center of this is CoreBridge, a standardized hardware interface currently in development that is intended to provide access to Yarbo's mechanical mounting points, power system, and data connections. It is designed to support third-party development and user-built extensions, allowing new types of functionality beyond pre-defined modules.
One example of this extensibility is an electromagnet-based module, which can be attached via CoreBridge to enable Yarbo to latch onto and move objects such as garbage bins. In a potential use scenario, this could enable automated movement of a bin to the curb on collection day and its return afterward.
This combination of software and hardware openness reflects an effort to expand the role of outdoor robotics beyond fixed-function devices.
Smart Assist Module Launch on Kickstarter
Alongside the Open Platform announcement, Yarbo is launching the Smart Assist Module (SAM) for the M Series on Kickstarter.
The module introduces two primary features designed to expand how users interact with their yard robot in everyday use:
- Follow Me Mode — enabling Yarbo to move alongside the user while carrying tools or materials, reducing the need for manual transport during yard work.
- Patrol Mode — allowing Yarbo to move along customizable routes around the property, with features such as remote live view, app-based alerts, and optional audio notifications via its built-in speaker, providing an added layer of awareness and convenience for users managing outdoor spaces.
The Smart Assist Module is positioned as part of Yarbo's broader effort to extend the practical use cases of its modular system.
Looking Ahead
The Yarbo Open Platform is planned for release in early 2027 and is being developed to support both the Y Series and M Series. By introducing a framework that combines software integration, developer tools, and hardware extensibility, Yarbo aims to enable a broader range of applications while allowing users to define how the system evolves over time.
Further details will be shared as development progresses.
About Yarbo
Yarbo is defining a new category of outdoor robotics with its Modular Yard Robot. Known for its automated snow blower robots, Yarbo introduced a modular system designed for year-round use. Powered by a single intelligent core unit, the system supports interchangeable modules for mowing, leaf blowing, snow clearing, and more—creating a more efficient approach to outdoor maintenance for homeowners.
