Understanding Epilepsy

Empowering Epilepsy Management: Beyond Medication and Surgery with tVNS®

Epilepsy is a neurological condition that affects millions worldwide, characterized by the tendency to have recurrent seizures. These seizures are the result of sudden, excessive electrical discharges in a group of brain cells. Different parts of the brain can be the source of these seizures, which can vary in frequency and intensity, profoundly impacting an individual’s quality of life.

The Challenge of Epilepsy Medication

Traditionally, epilepsy is managed with antiepileptic drugs (AEDs) aimed at controlling or reducing the frequency of seizures. While medication is effective for many, it’s not without its challenges. A significant number of patients continue to experience seizures despite medication, and side effects of AEDs can be substantial. These can range from mild inconveniences like fatigue and dizziness to more severe impacts on mood, cognitive function, and physical health.

Invasive VNS: A Historical Overview

For those whose seizures are not well-controlled by medication, invasive Vagus Nerve Stimulation (VNS) has been a treatment option for decades. This approach requires surgical implantation of a device that sends regular, mild pulses of electrical energy to the brain via the vagus nerve. While effective for some, the invasive nature of the procedure entails risks and potential complications, from infection to vocal cord paralysis, making it a less appealing option for others.

Introducing Non-Invasive tVNS®

Our device represents a groundbreaking advancement in the treatment of epilepsy: a non-invasive form of VNS that eliminates the need for surgery. By stimulating the vagus nerve through the skin at the cymba concha—an area of the ear with direct connections to the vagus nerve—tVNS® offers a safe and user-friendly alternative. This innovative approach harnesses the therapeutic potential of VNS while significantly reducing the risk of side effects and complications associated with invasive procedures.

With tVNS®, patients have access to a novel form of epilepsy management that is both effective and minimally intrusive, reflecting our commitment to improving the lives of those living with this challenging condition.

What is tVNS®?

Non-invasive vagus nerve stimulation for the treatment of epilepsy

Transcutaneous Vagus Nerve Stimulation (tVNS®) is an innovative approach to epilepsy management that offers a non-invasive, drug-free alternative to traditional treatments.

The vagus nerve, central to our body’s nervous system, plays a critical role in maintaining homeostasis. tVNS® 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 seizure frequency in epilepsy patients, 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.

The Science Behind tVNS®

The vagus nerve plays a pivotal role in regulating several bodily functions, including the brain’s electrical excitability. By targeting the auricular branch of the vagus nerve, specifically at the cymba concha region of the ear, tVNS® delivers electrical impulses that are believed to influence the brain’s seizure threshold. This targeted stimulation can help restore a balance to the nervous system’s activity, providing a new layer of control over epilepsy symptoms.

A Non-Invasive Solution

Unlike invasive Vagus Nerve Stimulation that requires surgical implantation of a device, tVNS® offers a significant advancement in treatment accessibility and patient comfort. The tVNS® device is externally applied, making it a convenient option for daily use without the risks or downtime associated with surgery. This ease of use empowers patients with epilepsy to incorporate tVNS® therapy into their regular routine, enhancing their overall quality of life and seizure management strategy.

Why tVNS® for Epilepsy?

For individuals living with epilepsy, especially those for whom medication is not sufficiently effective or who experience significant side effects from their current treatment plan, tVNS® presents a promising alternative. It opens the door to a more holistic approach to epilepsy management, focusing on the natural capabilities of the body’s nervous system to mitigate seizure activity.

In embracing tVNS®, patients and healthcare providers are accessing a cutting-edge tool in the fight against epilepsy, one that is backed by a growing body of clinical research and real-world evidence.

tVNS® offers a new hope for those seeking to reclaim their lives from the grip of seizures.

How does treatment with tVNS® work?

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

tVNS® harnesses the power of Transcutaneous Vagus Nerve Stimulation to offer an innovative, non-invasive therapy for epilepsy. This sophisticated treatment works by applying gentle electrical impulses to the auricular branch of the vagus nerve, accessible through the cymba concha area of the ear, a site with 100% vagus nerve innervation. Here’s a closer look at the mechanism and the benefits it brings to those living with epilepsy.

Targeted Neural Modulation

The essence of tVNS® lies in its ability to modulate the nervous system’s activity directly. By targeting the vagus nerve, tVNS® influences the brain’s neural circuits involved in seizure generation and propagation. The electrical impulses delivered by the device aim to reduce the excitability of these neural networks, decreasing the likelihood of seizure occurrence.

Restoring Balance

The vagus nerve plays a crucial role in maintaining the balance of the parasympathetic and sympathetic nervous systems. tVNS® stimulates this nerve to help restore equilibrium, reducing the frequency and intensity of epileptic seizures. This equilibrium not only impacts seizure control but also promotes a sense of overall well-being, as the vagus nerve is integral to functions like mood regulation and stress response.

A Convenient and Safe Therapy

Designed for daily use, tVNS® can be easily incorporated into the patient’s lifestyle without the need for invasive procedures or the risk of significant side effects associated with conventional epilepsy treatments. The device is applied externally, making it an ideal option for patients seeking a less invasive, more manageable approach to epilepsy care.

Clinically Supported

Emerging research and clinical trials underscore the potential of tVNS® as an effective adjunct therapy for epilepsy. With each study, we gain deeper insights into how this technology can be optimized to offer greater control over seizures, enhancing the quality of life for those with epilepsy.

Better days are ahead.

With its non-invasive approach, patient-friendly treatments, and minimal side effects, tVNS® offers a new horizon of hope and relief for those living with epilepsy. Embrace a future where each day holds the promise of greater comfort and enhanced quality of life.
