METHODS AND SYSTEMS FOR CHARGE BALANCING OF ELECTRICAL STIMULATION
An electrical stimulation system includes at least one electrical stimulation lead having stimulation electrodes; and a processor coupled to the at least one electrical stimulation lead to perform actions, including: directing delivery of at least one stimulation pulse to tissue of a patient during each charge injection phase, where each consecutive pair of the charge injection phases is separated by a charge recovery phase; and, for at least one stimulation pulse: during delivery of the stimulation pulse, directing application of at least one charge recovery pulse to interrupt the delivery of the stimulation pulse, where each one of the at least one charge recovery pulse has a relative amplitude that is larger in magnitude than an amplitude of the stimulation pulse; and, after application of the charge recovery pulse, directing resumption of delivery of the stimulation pulse at the amplitude of the stimulation pulse.
SYSTEMS AND METHODS UTILIZING PHASE-BASED BIOMARKER IN THE BRAIN
Embodiments of the present disclosure include a method for acquiring, with a device, a plurality of electrical signals from a brain of a subject, and determining whether a biomarker is present in the plurality of electrical signals. The biomarker comprises at least one phase metric associated with the electrical signal, and further includes adjusting at least one therapy parameter based on biomarker assessment.
Treatment of type 1 diabetes
Modulation of neural signaling of a pancreas-related sympathetic nerve is capable of improving glycaemic control by inhibiting T cell activation or migration to the pancreas, and hence providing a way of treating or preventing type 1 diabetes.
Method and apparatus for clinical effects-based targeting of neurostimulation
An example of a system for delivering neurostimulation may include a programming control circuit and a stimulation control circuit. The programming control circuit may be configured to generate stimulation parameters controlling delivery of the neurostimulation according to a stimulation configuration. The stimulation control circuit may be configured to specify the stimulation configuration, and may include volume definition circuitry and stimulation configuration circuitry. The volume definition circuitry may be configured to determine one or more test volumes, determine a clinical effect resulting from the one or more test volumes each being activated by the neurostimulation, and determine a target volume using the determined clinical effect. The stimulation configuration circuitry may be configured to generate the specified stimulation configuration for activating the target volume.
System for planning and/or providing neuromodulation
The present invention relates to systems and methods for planning and/or providing neuromodulation. An example system includes a first data input module for stimulation related basic data, a second data input module for stimulation related response data, a transfer module configured and arranged such that the stimulation related basic data received by the data input module are linked and/or translated into and/or with the response data and/or artificial response data created by the transfer module, wherein the data generated by the transfer module are transfer data, the transfer data comprising link data and/or translation data and/or artificial response data, and a mapping module configured and arranged such that based on the stimulation related basic data and stimulation related response data and the transfer data a digital characteristic map is generated, which describes an interrelation between the stimulation related basic data and the stimulation related response data and the transfer data.
MOTOR LEARNING AND VAGUS NERVE STIMULATION (VNS) PAIRED WITH MOTOR LEARNING TO TREAT DEMYELINATING DISEASES, CONDITIONS AND DISORDERS
Embodiments of the instant invention relate to applying motor learning to promote remyelination following demyelination in a subject having a condition or disease. In certain embodiments, applying motor learning alone or in combination with vagus nerve stimulation (VNS) induces the production of new and preserves surviving oligodendrocytes. In accordance with certain embodiments of the disclosure, motor learning, when properly timed, enhances oligodendrogenesis after injury and recruits mature oligodendrocytes to participate in remyelination through the generation of new myelin sheaths. In other aspects of the disclosure, VNS paired with motor learning enhances remyelination following demyelination.
Wireless neural stimulator with injectable
Neural stimulator systems with an external magnetic coil to produce changing magnetic fields is applied outside the body, in conjunction with one or more tiny injectable objects that concentrates the induced electric or magnetic field to a highly-targeted location. These systems include a driver circuit for the magnetic coil that allows for high voltage and fast pulses in the coil, while requiring low-voltage power supply that may be powered by a wearable or portable external device, along with the coil and driver circuit.
METHODS AND MATERIALS FOR TREATING NERVE INJURY AND/OR PROMOTING WOUND HEALING
This document relates to methods and materials for treating nerve injuries. For example, thermoresponsive compositions containing 4-aminopyridine (4-AP) and/or one or more derivatives of 4-AP as well as methods for using such thermoresponsive compositions as a delivery system for 4-AP and/or one or more derivatives of 4-AP (e.g., to treat nerve injury) are provided. This document also provides methods and materials for treating a wound (e.g., a skin wound). For example, compositions containing 4-AP and/or one or more derivatives of 4-AP can be administered (e.g., systemically administered) to a mammal having a wound (e.g., a skin wound) to treat the wound (e.g., to promote wound healing).
Electromyographic lead positioning and stimulation titration in a nerve stimulation system for treatment of overactive bladder
The present invention provides improved methods for positioning of an implantable lead in a patient with an integrated EMG and stimulation clinician programmer. The integrated clinician programmer is coupled to the implantable lead, wherein the implantable lead comprises at least four electrodes, and to at least one EMG sensing electrode minimally invasively positioned on a skin surface or within the patient. The method comprises delivering a test stimulation at a stimulation amplitude level from the integrated clinician programmer to a nerve tissue of the patient with a principal electrode of the implantable lead. Test stimulations are delivered at a same stimulation amplitude level for a same period of time sequentially to each of the four electrodes of the implantable lead. A stimulation-induced EMG motor response is recorded with the integrated clinician programmer for each test stimulation on each electrode of the implantable lead via the at least one pair of EMG sensing electrodes so as to facilitate initial positioning of the implantable lead at a target stimulation region.
SYSTEMS AND METHODS FOR RESTORING MUSCLE FUNCTION TO THE LUMBAR SPINE AND KITS FOR IMPLANTING THE SAME
A system for restoring muscle function to the lumbar spine to treat low back pain is provided. The system may include one or more electrode leads coupled to an implantable pulse generator (IPG) and a tunneler system for subcutaneously implanting a proximal portion of the lead(s). The system may also include a handheld activator configured to transfer a stimulation command to the IPG, and an external programmer configured to transfer programming data to the IPG. The stimulation command directs the programmable controller to stimulate the tissue in accordance with the programming data. The system may include a software-based programming system run on a computer such that the treating physician may program and adjust stimulation parameters.
