Abstract
Devices, systems and methods are provided for treating migraine headaches and other conditions by non-invasive electrical stimulation of nerves and other tissue. A hand-held device includes a housing with a controller having a signal generator, an electrode for delivering electrical signals, and a conductive surface configured as a return path for the electrical signals. In certain implementations, the electrode is repositionable with respect to the housing. The patient can self-apply the hand-held device by pressing it against areas in need of pain relief. The device may include a pressure-sensitive gating switch to control delivery of the stimulation therapy. In certain embodiments, the electrode is a rollerball electrode. The device may include a chamber for retaining and dispensing conductive gel to the therapy site. In certain approaches, the device includes an electrode support for coupling an electrical stimulation system to the head for hands-free electrical stimulation therapy.
