Abstract
A method for modulating nerve tissue in a body of a patient includes implanting a wireless stimulation device in proximity to a dorsal root ganglion or an exiting nerve root such that an electrode, circuitry and a receiving antenna are positioned completely within the body of the patient. An input signal containing electrical energy and waveform parameters is transmitted to the receiving antenna(s) from a control device located outside of the patient'"'"'s body via radiative coupling. The circuitry within the stimulation device generates one or more electrical impulses and applies the electrical impulses to the dorsal root ganglion or the exiting nerve roots through the electrode.
