Systems and methods for direct suppression of nerve cells
The present technology provides systems and methods for directly suppressing nerve cells by delivering electrical stimulation having relatively long pulse widths and at amplitudes below an activation threshold of the nerve cells. For example, some embodiments include delivering a therapy signal having individual pulses with pulse widths of between about 5 ms and 100 ms. Directly suppressing the nerve cells is expected to reduce the transmission of pain signals.
Systems and methods for automated deep brain stimulation programming
The systems and methods can automatically determine a patient-specific set of stimulation parameters using optimization for exploring and/or programming a neurostimulation device, e.g., deep brain stimulation (DBS). In one implementation, the method may include receiving patient data and set of stimulation parameters associated stimulation delivered to a patient by a neurostimulation device. The method may include determining one or more objective metrics using the patient data for each set of stimulation parameters. The one or more objective metrics may be a quantitative value that represents a rating or score of tremor severity and/or side effect severity. The method may further include generating a patient specific response model using the one or more objective metrics and the associated set of stimulation parameters. The method may also include applying an optimization algorithm to the generated response model to determine a candidate set of one or more stimulation parameters.
SYSTEMS AND METHODS FOR DETECTING EVOKED COMPOUND ACTION POTENTIAL (ECAP) FEATURES IN RESPONSE TO NEUROSTIMULATION
Systems and methods are disclosed for conducting spinal cord stimulation or other neurostimulation and sensing evoked compound action potential (ECAP) signals. The sensed signals may be processed to isolate ECAP features from noise and/or interfering signals. The isolated ECAP features may be used to control neurostimulation therapy for the patient and/or guide an implant procedure.

Electrode movement detection
Devices, systems, and techniques are disclosed for managing electrical stimulation therapy and/or sensing of physiological signals such as brain signals. For example, a system may assist a clinician in identifying one or more electrode combinations for sensing a brain signal. In another example, a user interface may display brain signal information and values of a stimulation parameter at least partially defining electrical stimulation delivered to a patient when the brain signal information was sensed.

In one example, a system may include processing circuitry configured to control a medical device to deliver a first electrical stimulation according to a first value of a first stimulation parameter of the plurality of stimulation parameters and a first value of a second parameter of the plurality of stimulation parameters, receive an input representative of an efficacy of the first electrical stimulation delivered to the patient according to the first value of the first stimulation parameter and the first value of the second parameter, select, based on the input and the relationship between the plurality of stimulation parameters, a second value of at least one of the first stimulation parameter or the second stimulation parameter, and control the medical device to deliver a second electrical stimulation according to the second value.
Device and method to selectively and reversibly modulate a nervous system structure to inhibit pain
The present disclosure is directed to a system and method for selectively and reversibly modulating targeted neural and non-neural tissue of a nervous system for the treatment of pain. An electrical stimulation is delivered to the treatment site that selectively and reversibly modulates the targeted neural- and non-neural tissue of the nervous structure, inhibiting pain while preserving other sensory and motor function, and proprioception.
ACHIEVING SMOOTH BREATHING BY MODIFIED BILATERAL PHRENIC NERVE PACING
A system for stimulating phrenic nerves to provide smooth breathing patterns is provided. More specifically, by identifying contraction threshold voltages for muscles associated with each of the left and right portions of a patient's diaphragm, a phrenic nerve pacing signal customized for each phrenic nerve may be provided to a patient. More specifically, a voltage of a pacing voltage provided to a first phrenic nerve may be less than the contraction threshold while a voltage of a pacing voltage provided to a second phrenic nerve may be greater than the contraction threshold.
Systems and methods of detecting and treating obstructive sleep apnea
A method of providing a sleep apnea nerve stimulation therapy to a subject may include detecting a respiratory waveform of the subject with a sensor. The sensor may be configured for coupling to the subject. The respiratory waveform may include a plurality of respiratory cycles each corresponding to at least one of a breath and an attempted breath of the subject. The method may also include identifying a breathing pattern within the respiratory waveform over a period of time. The breathing pattern may include a repeating pattern of a plurality of respiratory cycles followed by at least one respiratory cycle corresponding to a disordered breathing event. The method may also include generating a series of stimulation pulses with an implantable nerve stimulator configured for coupling to a hypoglossal nerve of the subject. The series of stimulation pulses may be coordinated with the breathing pattern.
METHOD AND APPARATUS FOR DETERMINING TOLERANCE THRESHOLDS FOR NEUROSTIMULATION
An example of a system for delivering neurostimulation using a stimulation device and controlling the delivery of the neurostimulation may include a programming control circuit and a stimulation control circuit. The programming control circuit may be configured to program the stimulation device for delivering the neurostimulation according to a pattern of neurostimulation pulses defined by one or more stimulation waveforms. The stimulation control circuit may be configured to determine the pattern of neurostimulation pulses with the one or more stimulation waveforms constrained by one or more thresholds, and may include threshold circuitry that may be configured to receive one or more known values of the one or more thresholds and to determine needed values of the one or more thresholds by executing an algorithm allowing for prediction of the needed values of the one or more thresholds based on the one or more known values.
