Assessment and Adjustment of Time-Varying Pulse Patterns in a Spinal Cord Stimulator System
Methods, system, and computer-implementable algorithms are disclosed for determining time-varying pulses for a patient having an implantable stimulator device (ISD). At least one time-invariant tonic stimulation pulse parameter (e.g., amplitude, pulse width, or frequency) is modified by a modulation function to produce time-varying pulses (TVPs), and one or more measurements are taken to determine the effectiveness of the TVP. The measurements may be objective and taken from the patient, and/or subjective and determined based on feedback from the patient. In one example, objective measurements may comprise one or more features determined from an electrospinogram (ESG) signal detected by the ISD, which may include evoked compound action potentials The one or more measurements are used to determine a score for the TVP, which is useful in selecting a best TVP for use with the patient, or for adjusting the modulation function applied to the tonic stimulation parameters.
Implant holder and suture guide
A delivery system is disclosed having an implant retainer configured to releasably hold an implant unit and maintain the implant unit in a fixation location relative to target tissue in a subject's body during an implantation procedure. A first suture guide portion may be disposed on a first side of the implant retainer and configured to guide a suture needle during the implantation procedure. A second suture guide portion may be disposed on a second side of the implant retainer, opposite the first side, and configured to guide the suture needle after the suture needle exits the first suture guide portion.
SELF-CALIBRATING SYSTEM FOR PRODUCING ELECTRICAL SIGNAL OUTPUT
One or more systems, computer-implemented methods and/or computer program products to facilitate a process to produce a specified electrical output are provided. A system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise an inverse modeling component that can generate an entity-based model and can determine updated one or more electrostatics parameters based on feedback relative to application of an electrical stimulation therapy employing an initial one or more electrostatics parameters on the entity. In one or more embodiments, a configuration component can determine the initial one or more electrostatics parameters based on an initial physical-based model based on an ideal entity, the configuration component can generate an initial physical-based model based on an ideal entity, and/or the inverse modeling component can update the initial model to generate the entity-based model.
Techniques to Allow Patient Control of the Location in an Electrode Array at Which Sub-Perception Stimulation is Provided to Spinal Neural Tissue of a Patient
A patient external controller is provided for controlling sub-perception stimulation provided by a patients implantable stimulator device having an electrode array. Control circuitry in the controller renders a graphical user interface (GUI), including a location at which the sub-perception stimulation is provided within the electrode array, and a pre-defined region in which the location can be moved. The pre-defined region may be constrained to less than the entire electrode array. The control circuitry receives one or more first inputs to move the location of the sub-perception stimulation within the region and to program the stimulator to move the sub-perception stimulation to the moved location in the electrode array. The control circuitry can enable adjustment of an amplitude of the sub-perception stimulation to a value that is less than or equal to a perception threshold. Once moved, the sub-perception stimulation an be stored as a second stimulation program.
Neural modulation of autonomic nervous system to alter memory and plasticity of the autonomic network
The present invention provides systems and methods for modulating the plasticity and/or memory of the autonomic nervous system.
Adaptive electrical neurostimulation treatment to reduce pain perception
Systems and techniques are disclosed to establish programming of an implantable electrical neurostimulation device for treating chronic pain of a human subject, through the use of a dynamic model adapted to determine pain treatment parameters for a human patient and identify a new device operational program to implement the pain treatment parameters to address the chronic pain condition. In an example, the system to establish programming of the neurostimulation device performs operations that: obtain state data indicating a measured value that is correlated to pain experienced by the human subject; determine neurostimulation programming parameters, using a dynamic model, for pain treatment in the human subject, as the dynamic model is used to identify values of the neurostimulation programming parameters that predict an improvement to the measured value; and indicate a neurostimulation program for the neurostimulation device, that includes the neurostimulation programming parameters for the implantable electrical neurostimulation device.

Systems and methods for treating a patient having a blood glucose abnormality, such as type 2 diabetes (T2D), using an electrical signal are disclosed. A representative method for treating a patient includes, based at least in part on a patient indication of a blood glucose abnormality, positioning at least one implantable signal delivery device proximate to a target location at the patient's spinal cord within a vertebral range of from about C8 to about T12. The method further includes directing an electrical signal to the target location via the implantable signal delivery device, wherein the electrical signal has a frequency in a frequency range of from 1.2 kHz to 100 kHz.
ELECTRODE POSITION DETECTION
Devices, systems, and techniques are disclosed for determining spatial relationships between electrodes implanted within a patient. In one example, a medical device delivers, via a first electrode, an electrical stimulus and senses, for each other electrode, a respective electrical signal indicative of the electrical stimulus. The medical device determines, for each other electrode, a respective value for each respective electrical signal. The medical device determines, based on the respective values for each respective electrical signal and values of tissue conductivity of tissues of the patient interposed between the first electrode and the other electrodes, spatial relationships between the first electrode and each other electrode of the plurality of electrodes.
Methods and devices for activating brown adipose tissue using electrical energy
Methods and devices are provided for activating brown adipose tissue (BAT) using electrical energy. In general, the methods and devices can facilitate activation of BAT to increase thermogenesis. The BAT can be activated by applying an electrical signal thereto that can be configured to target sympathetic nerves that can directly innervate the BAT. The electrical signal can be configured to target the sympathetic nerves using fiber diameter selectivity. In other words, the electrical signal can be configured to activate nerve fibers having a first diameter without activating nerve fibers having diameters different than the first diameter. Sympathetic nerves include postganglionic unmyelinated, small diameter fibers, while parasympathetic nerves that can directly innervate BAT include preganglionic myelinated, larger diameter fibers. The electrical signal can be configured to target and activate the postganglionic unmyelinated, small diameter fibers without activating the preganglionic myelinated, larger diameter fibers.
