DELIVERY OF INDEPENDENT INTERLEAVED PROGRAMS TO PRODUCE HIGHER-FREQUENCY ELECTRICAL STIMULATION THERAPY

The techniques of the disclosure describe example medical devices, systems, and methods for interleaving a plurality of low-frequency electrical stimulation pulse trains delivered by a plurality of sets of electrodes of an implantable medical device (IMD) to effectively deliver a combined high-frequency electrical pulse train to a target tissue area. In one example, each set of the plurality of sets of electrodes has a unique anode and cathode. In another example, a clinician adjusts the size or shape of the target tissue area receiving the combined high-frequency electrical pulse train by selecting different combinations of the plurality of sets of electrodes.
