Occipital Nerve Stimulation (ONS) therapy consists of applying mild electrical stimulation to the nerves via wires implanted just under the skin, near the occipital nerves at the base of the head. The wires are connected to an implanted battery that generates the stimulation, which interferes with pain signals and may evoke the sensation of tingling or paresthesia.

The AnkerStim™ lead is a new product that is CE mark approved for ONS for Intractable Chronic Cluster Headache (iCCH). ONS is intended to reduce the number of cluster headache attacks before they start and has shown promise as a therapy for iCCH – being able to reduce the frequency and intensity of attacks and medication use in some patients.
