Vagus Nerve Stimulator

A vagus nerve stimulator is a medical device that delivers electrical impulses to the vagus nerve. It is surgically implanted under the skin in the chest and connected to the vagus nerve in the neck. The device is used to treat various conditions by modulating brain activity through nerve stimulation.

This device is primarily used for individuals with epilepsy who have not responded to medication, and for those with treatment-resistant depression. It is also being investigated for other conditions such as cluster headaches and inflammatory bowel disease. The stimulation parameters can be adjusted by a healthcare professional to suit individual patient needs.
