Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 6:
7. A neuromodulator for providing therapy to a target neural tissue of a patient, the neuromodulator comprising:
a first input source operative to generate a first input waveform;
a second input source operative to generate a second input waveform;
a first and a second pair of electrodes attachable at respective locations relative to the target neural tissue of the patient, wherein the respective locations are determined based on interrogating a temporal interference (TI) pattern database having a plurality of TI patterns for different combinations of electrode placement configurations, number of electrode pairs, a range of amplitudes corresponding respectively to a first input waveform and a second input waveform, and a range of frequencies corresponding respectively to the first input waveform and the second input waveform; and
a controller configured to control the first and second input sources for:
applying the first input waveform to the first pair of the electrodes, the first input waveform having a first amplitude and a first frequency; and
applying the second input waveform to the second pair of the electrodes, the second input waveform having a second amplitude and a second frequency, wherein the second frequency is configured to be different from the first frequency such that the first and second input waveforms combine, when substantially simultaneously applied, to generate a beat waveform having a beat frequency due to interference, the beat waveform causing a temporal interference (TI) electric field having an interference region at least partially overlapping the target neural tissue of the patient, wherein the beat frequency is of a value operative to impart a therapeutic effect to the target neural tissue.
