Autonomix Medical, Inc. Granted Key U.S. Patent for Innovative Catheter-Based Platform Technology

Patent strengthens Autonomix’s intellectual property position in the nerve-mapping and denervation space, supporting the Company’s broader mission to advance minimally invasive, nerve-focused therapeutics

Company continues to expand its growing global patent portfolio with over 80 issued patents and 40 pending patent applications

THE WOODLANDS, TX, May 15, 2025 (GLOBE NEWSWIRE) --  (NASDAQ: AMIX) (“Autonomix” or the “Company”), a medical device company dedicated to advancing precision nerve-targeted treatments, today announced the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 12,257,071 (‘071 patent) titled Controlled sympathectomy and micro-ablation systems and methods. The newly issued ‘071 patent relates to, but is not necessarily limited to, advanced catheter-based systems that combine nerve mapping and radiofrequency (RF) ablation technologies, providing enhanced precision in treating nerve-related conditions. These systems allow for the identification and ablation of overactive nerves within the peripheral nervous system using a minimally invasive approach. The granted patent represents a significant step forward in Autonomix’s mission to improve patient outcomes by delivering more effective, less invasive treatments for neurological conditions such as chronic pain, hypertension and a myriad of other nerve-related disorders.

“We are excited to announce the issuance of this patent, marking a key milestone in our strategy to transform pain management and treat neurological disorders through minimally invasive, catheter-based denervation. This innovative technology enhances our intellectual property position in the rapidly growing nerve-focused therapeutics space, allowing us to protect our offerings and deliver improved solutions for both clinicians and patients. This patent is a vital addition to our expanding portfolio as we continue working toward our goal of revolutionizing the treatment of nerve-related conditions,” commented Brad Hauser, CEO of Autonomix.

In particular, the ‘071 patent covers key features of the technology including, but not necessarily limited to: Deployable microfingers with embedded sensors for real-time physiological monitoring; Ability to map, stimulate, ablate, and assess nerve activity in a single integrated system; Feedback-driven control of multiple types of procedures such as RF ablation, ultrasound, or chemical delivery; and Supports adaptive modulation to adjust therapeutic output in real-time based on inputs like EMG, MMG, and bioimpedance. The technology is designed to treat conditions influenced by sympathetic nerve activity, including renal denervation for hypertension, chronic pain syndromes, cardiac modulation and metabolic and neurological disorders.

Autonomix’s first-in-class technology platform utilizes a catheter-based microchip sensing array antenna that may have the ability to detect and differentiate neural signals with greater sensitivity than currently available technologies. Once target nerves are identified, Autonomix uses its proprietary RF ablation technology to kill targeted nerves, enabling a precision guided sense, treat and verify approach to addressing a number of disease categories from chronic pain management to hypertension and cardiology. Current approaches, primarily relying on opioids or invasive ethanol injections, can provide only limited relief and may lead to risky side effects.

The Company expects to submit an Investigational Device Exemption (IDE) and commence U.S. clinical trials in 2025 to support a labeling indication to commercialize the Autonomix Sensing and RF Ablation System in the U.S. as a treatment for pancreatic cancer pain.

About Autonomix Medical, Inc.

Autonomix is a medical device company focused on advancing innovative technologies to revolutionize how diseases involving the nervous system are diagnosed and treated. The Company’s first-in-class platform system technology includes a catheter-based microchip sensing array that may have the ability to detect and differentiate neural signals with greater sensitivity than currently available technologies. We believe this will enable, for the first time ever, transvascular diagnosis and treatment of diseases involving the peripheral nervous system virtually anywhere in the body.

We are initially developing this technology for the treatment of pain, with initial trials focused on pancreatic cancer, a condition that causes debilitating pain and is without a reliable solution. Our technology constitutes a platform to address dozens of potential indications, including cardiology, hypertension and chronic pain management, across a wide disease spectrum. Our technology is investigational and has not yet been cleared for marketing in the United States.
