REsponse to Combined SuPra-orbital and Occipital Nerve Stimulation in Chronic Cluster headachE With the PRIMUS System, a First in Human Study

The purpose of this study is to demonstrate the safe use of the PRIMUS System in subjects with chronic cluster headache. This is a single-centre, open label, prospective, first in human study to collect initial clinical data on the PRIMUS system for the treatment of chronic cluster headache.
