A method and system are provided to deliver nested stimulation to brain tissue of interest. The method and system set first parameters that define a carrier waveform. The method and system set second parameters that define a high frequency waveform, wherein at least one of the carrier waveform and high frequency waveform are defined to correspond to physiologic neural oscillations associated with the brain tissue of interest. The method and system operates a pulse generator to generate a nested stimulation waveform that combines the carrier waveform and high frequency waveform. The nested stimulation waveform has a plurality of pulse bursts. The method and system deliver the nested stimulation waveform through one or more electrodes to the brain tissue of interest.

A method for multi-carrier processing in an auditory prosthetic device comprises receiving an audio signal comprising multiple signals, each produced by an independent source, and identifying at least a first signal and a second signal in the received audio signal. The method also comprises adjusting an amplitude of a first carrier signal based on a first signal or a signal envelope associated with the first signal, and adjusting an amplitude of a second carrier signal based on a second signal or a signal envelope associated with the second signal. The amplitude-adjusted first and second signals are delivered to one or more stimulation devices associated with an auditory prosthetic.

Electrical stimulation therapy is provided to a patient in order to induce a patient sensation. The patient sensation may be selected from a number of patient sensations. A set of therapy parameter values are associated with each of the number of patient sensations. A user interface allows a user to adjust one or more characteristics of the patient sensation.

A neurostimulation system comprises a user input device configured for receiving input from a user, and processing circuitry configured for (a) selecting a first electrode configuration in response to receiving the user input, (b) predicting a neural response induced by electrical energy theoretically conveyed by the first electrode configuration at a specified amplitude, (c) deriving a metric value from the predicted neural response, (d) comparing the metric value to a reference threshold value, (e) adjusting the specified amplitude of the electrical energy if the metric value is not in a specified range relative to the reference threshold value, (f) repeating steps (b)-(e) using the adjusted amplitude as the specified amplitude until the metric value is in the specific range relative to the reference threshold value, and (g) instructing a neurostimulation device to deliver the electrical energy at the adjusted amplitude via the first electrode configuration to stimulate the patient.

The disclosure describes a method and system that allows a user to configure electrical stimulation therapy by defining a three-dimensional (3D) stimulation field. After a stimulation lead is implanted in a patient, a clinician manipulates the 3D stimulation field in a 3D environment to encompass desired anatomical regions of the patient. In this manner, the clinician determines which anatomical regions to stimulate, and the system generates the necessary stimulation parameters. In some cases, a lead icon representing the implanted lead is displayed to show the clinician where the lead is relative to the 3D anatomical regions of the patient.

Apparatus and methods for managing pain uses separate varying electromagnetic fields, with a variety of temporal and amplitude characteristics, which are applied to a particular neural structure to modulate glial and neuronal interactions as a mechanism for relieving chronic pain. In another embodiment, a single composite modulation/stimulation signal which has rhythmically varying characteristics is used to achieve the same results as separate varying electromagnetic fields. Also, disclosed is an apparatus and method for modulating the expression of genes involved in diverse pathways including inflammatory/immune system mediators, ion channels and neurotransmitters, in both the Spinal Cord (SC) and Dorsal Root Ganglion (DRG) where such expression modulation is caused by spinal cord stimulation or peripheral nerve stimulation using the disclosed apparatus and techniques. In one embodiment of multimodal modulation therapy, the prime signal may be monophasic, or biphasic, in which the polarity of the first phase of the biphasic prime signal may be either cathodic or anodic while the tonic signal may be either monophasic, or biphasic, with the polarity of the first phase of the biphasic tonic signal being either cathodic or anodic.

The cranial electrostimulation devices described herein are suitable for use in detoxification from and amelioration of the symptoms of acute and chronic withdrawal from simultaneous multiple addictive substances by transcutaneous electric nerve stimulation. A plurality of time-division multiplexed analog waveforms is applied to the mastoid process of a person in need thereof, thereby treating symptoms of withdrawal from addictive substances. The invention also provides a protocol for encoding a plurality of different waveforms combined sequentially or simultaneously, as well as an improved cranial electrostimulation apparatus having a stable output waveform signal over the useful service life of the power supply, e.g., the battery.
