What is tVNS®?

Elevating patient treatment options with non-invasive vagus nerve stimulation for the treatment of neurological diseases

When traditional pharmacological or invasive treatments fall short or present challenging side effects, tVNS® offers an effective and patient-friendly treatment option.

The vagus nerve, central to our body’s nervous system, plays a critical role in maintaining homeostasis. tVNS®, or Transcutaneous Vagus Nerve Stimulation, harnesses the therapeutic potential of this nerve through targeted stimulation of its auricular branch, accessible within the ear.

This innovative approach utilizes gentle electrical impulses to modulate the vagus nerve’s activity, encouraging a state of balance across the body’s systems. The result? A reduction in the symptoms of neurological diseases associated with sympathovagal imbalance, achieved through a method that avoids the invasiveness of surgery and the side effects associated with medication. Approved as a Class IIa medical device under the European Medical Device Regulation (MDR), tVNS® sets a new standard in the treatment of neurological conditions, offering a blend of efficacy, safety, and simplicity.

tVNS® is indicated to treat the following conditions:

How does treatment with tVNS® work?

Patients can use tVNS® anytime, anywhere. It's easy to use, portable, and discrete.

Treatment with tVNS® is characterized by its simplicity and adaptability to everyday life. At its core, tVNS® operates on the principle of neurostimulation, a process that engages the vagus nerve’s capacity to influence various bodily functions and systems. tVNS® stimulates the auricular branch of the vagus nerve (ABVN) through the skin with gentle and precise electrical impulses that propagate therapeutic signals to the brain, first to the brain stem and then to higher centers, aiming to correct dysregulation within the nervous system.

The application of tVNS® is designed with the patient in mind: it is easy, portable, and discreet, making it possible to incorporate treatment sessions into your schedule without interruption to your daily tasks. Whether you’re at home, in the office, or traveling, tVNS® provides a consistent and accessible means to manage symptoms of neurological disorders, including the reduction of seizure frequencies in epilepsy, among other conditions.

Each session with the tVNS® device is a step towards rebalancing the nervous system, leveraging the natural pathways of the body to foster healing and symptom relief. The device’s ease of use ensures that starting and maintaining a regimen with tVNS® is straightforward, empowering users to take control of their health in a non-intrusive, effective manner.
