Systems and Methods for Monitoring Neural Activity A method of monitoring neural activity responsive to a stimulus in a brain or a subject under general anaesthetic, the method comprising: applying the stimulus to one or more of at least one electrode implanted in a target neural structure of the brain; detecting a resonant response from the target neural structure evoked by the stimulus at one or more of the at least one electrode in or near the target neural structure of the brain; and determining one or more waveform characteristics of the detected resonant response.

An apparatus and method for providing split stimulation currents in a pulse generator. In one embodiment, a current regulator of the pulse generator includes a digitally-programmable analog voltage generator coupled to a first input of an error amplifier that receives a second input controlled by a programmable resistor network configured to control a programmable total stimulation current output. A plurality of current splitting switches are operative to split the programmable total stimulation current output into a corresponding plurality of split current segments, which may be individually mapped to a selected set of lead electrodes across one or more implantable leads associated with the pulse generator.

The present disclosure provides systems and methods relating to neuromodulation. In particular, the present disclosure provides systems and methods for eliminating the onset response when blocking nerve conduction. The various embodiments disclosed herein include methods for designing waveforms that block nerve conduction without inducing an onset response, and systems for delivering treatment based on these waveforms to subjects with pathological neural activity.

A neuromodulation system and method with feedback optimized electrical field generation for stimulating target tissue of a patient to treat neurological and non-neurological conditions. The system generally includes implantable electrodes, implantable sensors, an implantable or external electrical signal generator, and an implantable or external controller. The controller controls the electrical signal generator to generate electrical noise stimulation signals that are delivered to the target tissue via the electrodes and that produce an optimized electric field having maximized voltage with low current density. The sensors produce temperature and impedance data for the target tissue and the controller automatically responds to values of the sensor data that indicate potential damage to the target tissue to reduce the strength of the electric field.

Systems for treating obstructive sleep apnea having an implanted stimulator with an internal sensor configured to generate sensory data corresponding to movement of the thoracic or abdominal cavity of a patient during respiration. The system includes a wireless communications link between the stimulator and at least one external sensor for sensing a patient's physiological parameter and is used to augment the sensory data from the internal sensor. The stimulator includes a stimulation system configured to deliver electrical stimulation to a nerve which innervates an upper airway muscle, such as the hypoglossal nerve to treat sleep apnea.

A method, apparatus, and system for controlling a deep brain stimulation system. Internal sensor data is received for a group of internal parameters that relate to an operation of the deep brain stimulation system. The internal sensor data is generated by an internal sensor system. External sensor data is received for a group of external parameters for an environment around the device. The external sensor data is generated by an external sensor system. The internal sensor data and the external sensor data are analyzed with aggregated internal sensor data and aggregated external sensor data for deep brain stimulation systems of a same class as the deep brain stimulation system to generate results. An operation of the device is controlled based on the results.

Systems and methods are provided for delivering neurostimulation therapies to patients. A titration process is used to gradually increase the stimulation intensity to a desired therapeutic level until a target T-wave alternans change from a baseline T-wave alternans is achieved.

Described herein are systems and methods for the treatment of pain using electrical nerve conduction block (ENCB). Contrary to other methods of pain treatment, the ENCB can establish a direct block of neural activity, thereby eliminating the pain. Additionally, the ENCB can be administered without causing electrochemical damage. An example method can include: placing at least one electrode contact in electrical communication with a region of a subject's spinal cord; applying an electrical nerve conduction block (ENCB) to a nerve in the region through the at least one electrode contact; and blocking neural activity with the ENCB to reduce the pain or other unwanted sensation in the subject.

Methods for electrical modulation of inflammation or serum TNF levels in a subject.

A method for remote programming a therapy device for neurostimulation comprises: generating a stimulation program for the therapy device by means of a clinician programmer; transferring the stimulation program to a patient programmer; loading the stimulation program on the therapy device from the patient programmer; and increasing a stimulation amplitude of the stimulation program by means of the patient programmer. An initial stimulation amplitude setting of the stimulation program is limited to a minimal dose amplitude.
