Miniature wireless system for deep brain stimulation

An implantable system for performing deep brain stimulation, the system comprising:

• an implantable inductor on which a voltage is induced when subjected to an electromagnetic field;
• and
• an implantable device comprising a housing, conductive stimulating elements located and formed on an exterior surface of the housing, and electronics within the housing and electrically connected to the implantable inductor, the electronics producing a brain-stimulating current from the voltage induced on the implantable inductor and then delivering the brain-stimulating current to the stimulating elements;
• wherein the housing and the stimulating elements are configured for deep brain implantation together;
• wherein the stimulating elements are spaced apart at the exterior surface of the housing and comprise at least two two-dimensional structures located and formed on the exterior surface of the housing or at least two three-dimensional structures that protrude through the exterior surface of the housing;
• and
• wherein the implantable inductor is entirely outside the housing of the device and has a flat coil configuration that enables the implantable inductor to be implanted separate from the housing and the stimulating elements, between the skull and the scalp and lie flat against the skull.
