US Patent 9393401 Wearable transdermal neurostimulator having cantilevered attachment

Neurostimulator apparatuses for applying transdermal electrical stimulation that may be comfortably and securely worn on a variety of head shapes and sizes. The apparatuses and methods of using them described herein may be lightweight and wearable and configured to be attached at one end of a patient-facing surface of the apparatus by a cantilevered attachment so that an opposite end of the surface is free to float relative to the user's head. The cantilevered attachment may include two or more connectors spaced apart along an edge region of the patient-facing surface in an optimal arrangement to secure the neurostimulator in place. The neurostimulator apparatuses described herein may be secured to a separate or integral electrode assembly that may adhesively secure to the subject's head. The patient-facing surface of the neurostimulator may also be curved and twisted specifically for use at the temple/forehead region of a diverse population of potential users.
