Worn daily or while sleeping, our earbud device will be used to reduce symptoms of PTSD, while promoting faster recovery from traumatic events by delivering neurostimulation that responds to your own body’s stress signals.

Our non-invasive platform technology (transcutaneous VNS or tVNS) will be scalable to treat other indications including mild cognitive impairment, depression, epilepsy, anxiety, ADHD, OCD, insomnia, and autism spectrum disorder.


The Phoenix

The Phoenix device is designed to fit discreetly in your ear to provide continuous therapy without bringing unwanted attention to your treatment or condition.

Proven Results 

Our initial product is based on transcutaneous vagal nerve stimulation (tVNS). Multiple pre-clinical and clinical studies have shown VNS to significantly reduce the symptoms of PTSD.

How VNS Works

Using your own body rhythms, the Evren device will provide personalized therapy that is continuously customized to your needs.

"The Phoenix is a potential game changer in the treatment of stress related disorders and PTSD.   The Phoenix incorporates state of the art neuroscience and technology in an innovative design that resembles an earbud.  Unlike other forms of vagal nerve stimulators, the Phoenix is a wearable with unique capabilities to  monitor, evaluate, and interpret the impact of stimulation on dynamic change in vagal efferent function.  By using the individual’s own vagal efferent pathways,  the Phoenix optimizes vagal nerve stimulation to improve positive outcomes including stress reduction, feeling of calmness, and better sleep profiles."
