  • Patent number: 10716932
    Abstract: Improved stimulation circuitry for controlling the stimulation delivered by an implantable stimulator is disclosed. The stimulation circuitry includes memory circuitry that stores pulse programs that define pulse shapes, steering programs that define electrode configurations, and aggregate programs that link a selected pulse program with a selected steering program. Each steering program defines the stimulation polarity and the allocation of current of the specified stimulation polarity for each of the pulse generator's electrodes. Each pulse program includes one or more pulse instructions, where each instruction defines the parameters of a single phase of the pulse program. Pulse definition circuits in the stimulation circuitry execute aggregate programs to generate stimulation waveforms, which stimulation waveforms can be generated simultaneously by the different pulse definition circuits.

  • Patent number: 10682516
    Abstract: Methods for identifying responders to paresthesia-free stimulation therapy, and associated systems are disclosed. A representative method comprises implanting a pair of spinal cord signal delivery devices and connecting an external signal generator thereto. A plurality of the electrical contacts are simultaneously activated with a high frequency signal without causing paresthesia in the patient, wherein the electrical contacts would cause paresthesia in the patient if activated with a low frequency signal. The high frequency signal is in a range of from about 3 kHz to about 20 kHz and an amplitude of less than 4 mA. If the patient responds favorably, a signal generator is implanted in the patient. A second high frequency signal is then applied to fewer than the plurality of electrical contacts.

  • Patent number: 10668285
    Abstract: It has been discovered that pain felt in a given region of the body can be treated, not by motor point stimulation of muscle in the local region where pain is felt, but by stimulating muscle spaced from a “nerve of passage” in a region that is superior (i.e., cranial or upstream toward the spinal column) to the region where pain is felt. Spinal nerves such as the intercostal nerves or nerves passing through a nerve plexus, which comprise trunks that divide by divisions and/or cords into branches, comprise “nerves of passage.

  • Patent number: 10610690
    Abstract: A fully implantable trial neurostimulation system for implant within a patient is provided that includes one or more leads equipped to deliver neurostimulation to patient tissues under the control of a trial neurostimulation control device designed as a capsule for removable implant within the patient. The control capsule is provided with minimal components to power and control the delivery of neurostimulation during a trial evaluation period and is shaped and configured to facilitate removal from the patient following completion of the trial period. In some examples, both the lead and the trial control capsule are removed from the patient following the trial period for replacement with a chronic or long-term neurostimulation system (assuming further neurostimulation is warranted.) In other examples, the lead remains within the patient and the trial control capsule is replaced with a long-term neurostimulation controller device. Various minimally-intrusive implantation procedures are also described.

  • Patent number: 10569091
    Abstract: Methods and devices are provided for, under control of one or more processors within an implantable medical device (IMD), delivering cardiac resynchronization therapy (CRT) at one or more pacing sites. The processors obtain cardiac signals, associated with a candidate beat, from multi-site left ventricular (MSLV) electrodes distributed along a left ventricle and analyze the cardiac signals to collect at least one of a MSLV conduction pattern or a MSLV morphology. The processors compare at least one of the MSLV conduction pattern or MSLV morphology to one or more associated templates. The processors then label the candidate beat as a pseudo-fusion beat based on the comparing and adjust the CRT based on the labeling.

    Abstract: A method and external control device for providing therapy to a patient using first and second electrodes implanted within the patient is provided. A train of electrical multi-phasic pulses is generated. A first electrical current is sourced from the second electrode and at least a portion of the first electrical current is sunk to the first electrode during a stimulation phase of each multi-phasic pulse, thereby therapeutically stimulating a first tissue region adjacent the first electrode. A second electrical current is sourced from the first electrode and at least a portion of the second electrical current is sunk to the second electrode during a charge recovery phase of each multi-phasic pulse, thereby recovering at least a portion of the charge that had been injected into the patient during the stimulation phase of each multi-phasic pulse, and therapeutically stimulating a second tissue region adjacent the second electrode.

  • Patent number: 10456576
    Abstract: Devices, systems and methods for reducing migration of leads, catheters and similar devices are provided. In particular, devices, systems and methods are provided for creating a slack anchor which assists in maintaining the lead or catheter in a desired position. In some embodiments, the slack anchor is created within the epidural space. When targeting nerve anatomy within the spinal column or in the vicinity of the epidural space, anchoring within the epidural space allows the associated lead or catheter to be anchored as close to the target therapy site as desired or possible. By anchoring close to the target therapy site, the risk of movement or migration is significantly reduced or eliminated.

  • Patent number: 10434313
    Abstract: We disclose multi-electrode, energy-recycling, resonant stimulation circuits and strategies for energy-efficient blocking of action potentials in nerve. Our schemes increase the probability that most of the electrical stimulation is directed through the nerve rather than dissipated in ohmic extracellular solution alongside it via mechanical and electrical means; they use energy-recycling and resonant-amplification strategies that recycle and amplify capacitive nerve energy such that the nerve itself becomes an integral part of the circuit creating its oscillatory blocking waveform; they use traveling-wave strategies with distributed multi-electrode stimulation that alters the timing and intensity of stimulation at various points along the nerve to synchronize blocking stimulation with wave propagation in the nerve in an energy-efficient fashion.
