Rise Above PTSD™

Andy's Story

The Evren Phoenix has not been approved by FDA

and its safety and effectiveness has not yet been established.


to treating PTSD

Evren Technologies has developed non-invasive bioelectronic medical devices that use vagus nerve stimulation (VNS) to lessen or alleviate symptoms of post-traumatic stress disorder (PTSD).


Caution: Investigational Device. Limited by Federal (or United States) Law to Investigational Use.

does PTSD matter?

PTSD is a devastating psychiatric disorder caused by exposure to a horrific or life-threatening trauma.  People with PTSD have difficulty sleeping, nightmares, persistent frightening flashbacks, sudden pathologically-intense outbursts of anger, violence, or anxiety, feel numb or detached, and avoid “triggers” (people or places that remind them of the trauma).

​The clinical, social, and financial burdens are enormous.  The annual cost to society is estimated at over $232 billion. In the VA alone more than 900,000 veterans receive PTSD disability compensation.

What is VNS?

Vagus nerve stimulation (VNS) is a type of neuromodulation, which is a treatment that alters the activity of nerves. Vagus nerve stimulation involves implanting a device that sends regular, mild pulses of electrical energy to your brainstem through your vagus nerve in your neck. After reaching your brainstem, the electrical charge is discharged to different areas of your brain to change the way brain cells work.

What is the Vagus nerve?

The vagus nerve, also known as the vagal nerves, are the main nerves of your parasympathetic nervous system. This system controls specific body functions such as your digestion, heart rate and immune system. These functions are involuntary, meaning you can’t consciously control them.

VNS Research

The vagus nerve is critical in many therapeutic areas. It's beneficial in restoring balance to sympathetic activity that is abnormally raised, or parasympathetic activity that is lowered.   


A sample of what researchers are investigating:

  • VNS mechanisms of action 

  • Restoration of autonomic balance

  • Laying new neural pathways during tasks

  • Reduction of symptoms and systemic inflammatory responses
