Vagal nerve stimulators, or vagus nerve stimulators (VNS), are implantable devices used to treat a number of conditions, although the mechanism of action has not been completely elucidated.
Vagal nerve stimulators are indicated in patients with 1-3:
The internal pulse generator is typically inserted below the left clavicle and the leads traverse towards the vagus nerve, typically the left, in the lower neck.
The differential is that of other implantable devices in the chest (however the lead course should be obvious) such as:
