StimRelieve

StimRelieve was a private U.S. medical device company focused on minimally invasive wireless neuromodulation for chronic migraine and craniofacial pain. Its core technology used miniature, wirelessly powered implantable neurostimulators delivered through a needle-based procedure, with an external transmitter providing power instead of an implanted battery pack. The company advanced at least two named systems: the Halo CFNS System for refractory craniofacial neuropathic pain and the Halo Migraine System for chronic migraine. StimRelieve obtained FDA Investigational Device Exemption approvals and initiated clinical studies, but available business records indicate the company later became inactive/out of business. The company appears to have operated as a small, privately backed medtech venture rather than a commercial-stage biotech or pharma company.
