VARIABLE OPERATING POINT NEURAL ELECTROSTIMULATION SUCH AS TO TREAT RLS
Techniques to help improve efficiency or effectiveness of treating a disorder such as RLS or PLMD, such as by issuing neural electrostimulations to a particular patient, while varying one or more amplitude parameters (e.g., at least one of electrostimulation current amplitude, electrostimulation voltage amplitude, or electrostimulation pulsewidth duration). A corresponding patient-subjective or patient-objective response can be observed. A characteristic electrostimulation intensity relationship can be generated, for example, based on the determined respective at least one of RLS or PLMD response indication threshold amplitude parameters and the plurality of corresponding neural electrostimulation durations. Once this characteristic electrostimulation intensity relationship has been generated, it can then be used to control issuing subsequent neural electrostimulations to the particular patient according to (1) at least one goal and (2) a variable operating point based upon the generated characteristic electrostimulation intensity relationship.
Systems and methods for treating mental and neurological disorders involving abnormally high brain connectivity
A method of using deep brain stimulation (DBS) for treating mental disorders associated with high connectivity in brain circuits, such as cortico-striato-thalamo-cortical (CSTC) circuits, is provided. The method comprises providing a first electrical signal having a first frequency to a first electrode implanted at a first location within a brain circuit and providing a second electrical signal having a second frequency to a second electrode implanted at a second location within the brain circuit. The first frequency and the second frequency are unequal.
Neurostimulation induced medicine devices and related methods of use
Example neurostimulation induced medicine devices and methods of use are described herein. An example endotracheal device can include an elongate tubular member having a proximal end and a distal end, an inflatable cuff arranged between the proximal and distal ends of the elongate tubular member, and an electrode array disposed in proximity to an exterior surface of the inflatable cuff. The inflatable cuff can be configured to expand to contact a subject's tracheal wall. Additionally, the electrode array can include a plurality of flexible electrodes, where a set of the flexible electrodes anatomically align with a region of the subject's tracheal wall for selectively targeting vagus nerve activity.
AUTOMATIC ECAP ELECTRODE SELECTION AND MAINTENANCE
A system may include an implantable device and a controller. The implantable device may include sensing-capable electrodes. The controller may be configured to receive a trigger signal indicative of a trigger to evaluate sensing capabilities of the sensing capable electrodes, respond to the received trigger signal by evaluating the sensing capabilities of the sensing-capable electrodes to assess or reassess which of the sensing-capable electrodes are available to be activated for sensing ECAPs, activate at least one of the sensing-capable electrodes that are available to be activated based on the evaluating the sensing capabilities, and sense the ECAPs using the activated ones of the sensing-capable electrodes.
METHODS AND SYSTEMS FOR TARGET LOCALIZATION AND DBS THERAPY
Methods and systems are described for detecting if a stimulation lead implanted in a patient's brain has moved. Lead movement occurring between a first time and a second time may be determined by comparing features extracted from evoked potentials recorded at the two times. The disclosed methods and systems are particularly useful for determining if a stimulation lead has moved between the time it was implanted in the patient's brain and the time that stimulation parameters are being optimized. Lead movement during implantation, during parameter optimization, and during or between other lead optimization processes may be determined as well.
