Technology Overview
NEUROMARK is designed to consistently provide easy access and treatment coverage, including of the posterior regions of the lateral nasal wall.
More Posterior Placement
Flexible leaflets conform to patient anatomy, maximizing access to nerve-rich areas in the nasal cavity even in challenging anatomies.
Maximal Treatment Coverage
Numerous microablation sites spread over a wide treatment area disrupt posterior nasal nerve (PNN) pathways while maintaining mucosal and vascular integrity.¹⁻³
Real-Time Feedback
Real-time apposition confirmation helps guide leaflet placement with immediate visual feedback, while Smart Algorithms help prevent over- or under-treatment.
The NEUROMARK Experience in 3D
Neurent Medical is pioneering innovative treatments for chronic inflammatory sino-nasal diseases by targeting and safely disrupting hyperactive autonomic nerves that drive underlying inflammation, so patients can breathe better and live better.
Posterior Nasal Nerves and Chronic Rhinitis
A peripheral branch of the vidian nerve, the posterior nasal nerve (PNN) is the dominant source of the parasympathetic, sympathetic, and sensory fibers that innervate the nasal respiratory mucosa.⁴
Medications used to treat CR, such as intranasal saline, intranasal corticosteroids, oral or topical decongestants, and others may temporarily relieve symptoms; however, they fail to address the neural source of nasal hypersecretion and many patients do not receive benefit from medical management alone.⁵
PNN ablation may induce denervation of the nasal mucosa and suppress nasal hypersecretion by blocking autonomic vidian nerve fibers — similar to vidian neurectomy — as well as hypersensitivity by simultaneously blocking sensory nerve fibers to relieve nasal symptoms.⁴
NEUROMARK Mechanism of Action
The NEUROMARK System consists of a single-use, hand-held bipolar RF device and a reusable console with a graphical user interface (GUI).
The posterior nasal nerve network is diffuse and variable, and tissue characteristics can differ significantly from patient to patient. Neuromark is designed to account for that variability through impedance-controlled radiofrequency neurolysis. As energy is delivered, the system continuously measures tissue impedance across each treatment leaflet. Because impedance changes as tissue responds to therapy, Neuromark receives real-time biofeedback throughout the treatment cycle. Unlike fixed-time or temperature-controlled approaches that deliver energy for a predetermined amount of time, Neuromark adapts to the tissue response and automatically discontinues energy delivery when the intended treatment endpoint is reached. In shallower tissue that treatment endpoint is reached earlier than in deeper tissue. Three recommended placements provide broad coverage of the posterior nasal nerve network, while flexible leaflets conform to patient anatomy to access nerve-rich posterior regions. The result is patient-specific therapy guided by real-time tissue feedback, helping deliver sufficient treatment while minimizing the risk of under- or overtreatment. Not too little. Not too much. Just right.

The NEUROMARK System uses propriety ENTelligent technology™ to target the overactive posterior nasal nerves (PNN) that cause the symptoms of Chronic Rhinitis. NEUROMARK utilizes controlled low-energy radiofrequency (RF) to create precise micro-lesions at target sites.
The CLARITY clinical study shows statistically significant and clinically meaningful symptom improvements in patients who receive NEUROMARK, with an 80% responder rate for reflective Total Nasal Symptom Score (rTNSS) as defined by a 30% reduction from baseline at 12 months.
NEUROMARK is an option for both long-term and newly diagnosed allergic and nonallergic chronic rhinitis patients. In the PARAGON 6-month clinical study, both allergic and nonallergic subgroups experienced significant improvement in all study outcome measures (p<.001) with no significant differences between subgroups.¹⁰
Unlike medication, which requires compliance to a regular schedule¹¹, or surgery, which can be invasive and has a long recovery period, NEUROMARK treats symptoms directly at the source in a gentle, minimally invasive procedure.
Patients with common symptoms of Chronic Rhinitis such as excessive sneezing, rhinorrhea, postnasal drip, or frequent congestion may be good candidates for treatment. By recognizing these symptoms right away, you can help treat the source with NEUROMARK.
