  • Patent number: 11890473
    Abstract: An apparatus, system and technique selectively eliminates the noxious signal components in a neuronal signal by creating an interfering electrical signal that is tuned to a given frequency corresponding to the oscillatory pattern of the noxious signal, resulting in a modified neuronal signal that substantially reproduces a normal, no-pain neuronal signal. The disclosed system and technique of pain relief is based on the hypothesis that the temporal profile of pain signals encodes particular components that oscillate at unique and quantifiable frequencies, which are responsible for pain processing in the brain.

  • Patent number: 11850426
    Abstract: Software for providing a Graphical User Interface (GUI) for use in a clinician programmer for programming an implantable pulse generator (IPG) or external trial stimulator (ETS) is disclosed. A user may define in the GUI multiple pole configurations (e.g., monopoles, bipoles, etc.) which may be used independently to provide stimulation to a patient via the IPG or ETS's electrode array. Selected of the pole configurations can be linked or associated as a group in the GUI and used to concurrently provide stimulation. The pole configuration group may be steered or moved in the electrode array using a single movement instruction which moves all pole configurations in the group simultaneously. This allows the relative positions of the pole configurations in the group to remain constant as the group is moved.

    Abstract: An electrode system for neuromodulation and for recording of signals indicative of nerve activity is provided. The system can include a plurality of electrodes provided on a flexible, non-conductive substrate. The substrate can be rolled into a cuff for encircling a nerve bundle of a patient. The plurality of electrodes on the cuff can be interconnected using flexible conductors provided on the substrate. In one implementation, the electrodes can be interconnected using conductors that have spring-like configuration. Flexibility of the conductors allows the cuff to expand and contract with the nerve without causing excessive stress/strain at the nerve-cuff interface.

  • Patent number: 11833345
    Abstract: Implantable medical lead devices such as leads and lead extensions include conductors within the lead device body that interconnect proximal and distal electrical connectors and that have balanced clocked positions. The balanced clocked positions may be achieved by separating a first conductor from a second conductor by an adequate amount, where the first conductor has a length as measured from a given point along the lead to the end of the conductor that is most similar to the length of the second conductor as measured in the same manner. The balanced clocked position of conductor pairings based on similarity of length may provide benefits such as reducing the tendency of the lead to curve when one or more layers of the lead body are being injection molded around the conductors.

  • Patent number: 11826571
    Abstract: A closed loop control system automatically ensures that an output of a device is constant. The system can receive an input to set a fixed value for a variable (e.g., a current, a heart rate, a tissue perfusion, an ion level, etc.), and this variable can be delivered to a feedback component. The system can also include the device to deliver the variable to a load. The feedback component can be coupled to the delivery device to sample the output of the delivery device at different times. Based on the sampling, the feedback component can vary a property of the delivery device related to the delivery of the variable to the load to ensure that the variable remains constant at the fixed value. In some instances, the system can be implemented as a stimulator that delivers the constant current of a current source and has a low output impedance of a voltage source.

  • Patent number: 11813457
    Abstract: Systems, devices, and techniques are described for adjusting electrical stimulation based on detected ECAPs. In one example, a medical device includes processing circuitry configured to control stimulation circuitry to deliver a first electrical stimulation pulse and sensing circuitry to detect, after delivery of the first electrical stimulation pulse, an ECAP signal. The processing circuitry may be configured to determine a characteristic value of the ECAP signal, determine an ECAP differential value that indicates whether the characteristic value of the ECAP signal is one of greater than a selected ECAP characteristic value or less than the selected ECAP characteristic value, determine, based on the ECAP differential value, a gain value, determine, based on the gain value, a parameter value that at least partially defines a second electrical stimulation pulse, and control the stimulation circuitry to deliver the second electrical stimulation pulse according to the parameter value.
