  • Patent number: 11951310
    Abstract: A system for restoring muscle function to the lumbar spine to treat low back pain is provided. The system may include electrodes coupled to an implantable pulse generator (IPG), 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.

  • Patent number: 11937847
    Abstract: Systems and methods for enhanced implantation of an electrode lead for neuromuscular electrical stimulation of tissue associated with control of the lumbar spine for treatment of back pain, in a midline-to-lateral manner are provided. The implanted lead may be secured within the patient and used to restore muscle function of local segmental muscles associated with the lumbar spine stabilization system without disruption of the electrode lead post-implantation due to anatomical structures.

  • Publication number: 20230398346
    Abstract: A lead for providing neuromuscular electrical stimulation that enhances fatigue-resistance, as well as methods of use thereof, and methods for manufacturing the same, are provided. The lead has a proximal region, a distal region, a fatigue-resistant zone disposed between the proximal region and the distal region, and one or more conductors comprising individual strands that extend from the distal region to the proximal region substantially parallel to a longitudinal axis of the electrostimulation lead outside of the fatigue-resistant zone. The individual strands of one or more conductors are wound in a coiled configuration within the fatigue-resistant zone to enhance fatigue-resistance. Moreover, the fatigue-resistant zone is configured to be disposed at a location within the patient that experiences fracture-inducing shear forces caused by movement of the patient's lower back muscles.

  • Patent number: 11786725
    Abstract: 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.

  • Publication number: 20230321438
    Abstract: Systems and methods for enhancing muscle function of skeletal muscles in connection with a planned spine surgery intervention in a patient's back are provided. The method includes implanting one or more electrodes in or adjacent to tissue associated with one or more skeletal muscles within a back of a patient, the one or more electrodes in electrical communication with a pulse generator programmed for enhancing muscle function of the one or more skeletal muscles. Electrical stimulation is delivered, according to the programming during a time period associated with the planned spine surgery intervention, from the pulse generator to the tissue associated with the one or more skeletal muscles via the one or more electrodes, thereby improving neuromuscular control system performance of the one or more spine stabilizing muscles in connection with the planned spine surgery intervention to reduce the patient's recovery time associated with the planned spine surgery intervention.

  • Publication number: 20230302274
    Abstract: Systems and methods are provided for extracting an implanted lead from a patient's body. The system may include a dilator and a trephine for extracting the electrode lead. A sheath may be included that is advanced over the proximal end of an electrode lead until the distal end of the sheath abuts a collar of the electrode lead coupled to proximal fixation elements. The dilator may be rotatably and axially advanced over the sheath until the distal end of the dilator collapses the proximal fixation elements within a lumen of the dilator. The trephine may then be rotatably and axially advanced over the dilator such that a cutting edge of the trephine cuts tissue surrounding distal fixation elements of the electrode lead to thereby dislodge the electrode lead.

  • Patent number: 11684774
    Abstract: Apparatus and methods for treating back pain are provided, in which an implantable stimulator is configured to communicate with an external control system, the implantable stimulator providing a neuromuscular electrical stimulation therapy designed to cause muscle contraction to rehabilitate the muscle, restore neural drive and restore spinal stability; the implantable stimulator further including one or more of a number of additional therapeutic modalities, including a module that provides analgesic stimulation; a module that monitors muscle performance and adjusts the muscle stimulation regime; and/or a module that provides longer term pain relief by selectively and repeatedly ablating nerve fibers. In an alternative embodiment, a standalone implantable RF ablation system is described.
