2.1
gammaCore (electroCore) is a non-invasive vagus nerve stimulator used to treat and prevent cluster headaches. It is self-administered by the person or their carer. After applying conductive gel, gammaCore is held against the neck (over the cervical branch of the vagus nerve) and delivers a small electric current for about 2 minutes. This stimulation should be repeated 3 times. The device is small and portable. gammaCore requires RFID (radio frequency identification) card activation which is renewed every 3 months (93 days). The RFID card activation allows gammaCore to deliver a maximum of 30 stimulations in each 24‑hour period. Conductive gel is provided with each new RFID card. Additional gel can be provided at no extra cost.
