What Happens During Vagus Nerve Stimulation Treatment
Prep for surgery:
On the day of surgery, you’ll take an antibiotic to lower the risk of an incision-related infection.
Your neck and chest are cleaned for surgery. You may have the surgery performed under local anesthesia, with medication to numb the surgical areas. More commonly, you may be given general anesthesia to keep you asleep during the procedure.
Vagus nerve stimulation device:
The vagus nerve stimulation device consists of a vagus nerve stimulator (pulse generator) device and a wire lead (insulated wire) with electrodes at the end of the wire.
Device implantation:
Your surgeon begins by making two incisions (cuts), one on the left side of your neck to expose your vagus nerve and the other on your upper left chest. The coil electrodes at the end of the lead wire are gently wrapped around your left vagus nerve through the incision made in your neck. Your surgeon then guides the insulated lead wire extending from the electrodes from your neck and down to your chest at the chest incision. They then connect the end of the electrode to a battery. The battery is a little bigger than a silver dollar. It goes through the incision into your chest into a pocket made over your muscle.
Device initial testing:
Once the device, lead wire and electrodes are implanted, the system is tested. The device is usually turned on at the lowest setting for 30 seconds to 90 seconds to make sure it’s stimulating your vagus nerve. Your surgeon then tests the system. Finally, they sew the device to your pectoralis fascia (a thin collagen layer covering your pectoralis major muscle) with permanent stitches (sutures).
