  • Patent number: 10695567
    Abstract: A neurostimulation paddle lead, method of neurostimulation, and neurostimulation system are provided. The neurostimulation paddle lead carries a plurality of electrodes comprising at least four columns of electrodes having a spacing between two inner electrode columns less than a spacing between the inner electrode columns and adjacent outer electrode columns. The inner electrode columns may also be longitudinally offset from the outer electrode columns. The methods and neurostimulation systems steer current between the electrodes to modify a medial-lateral electrical field created adjacent spinal cord tissue.

  • Publication number: 20200197704
    Abstract: Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which active electrodes are selected for the patient. This allows sweet spot searching to occur much more quickly and without the need to wash in the various electrode combinations that are tried. After selecting electrodes using supra-perception therapy, therapy is titrated to sub-perception levels using the selected electrodes. Such sub-perception therapy has been investigated using pulses at or below 10 kHz, and it has been determined that a statistically significant correlation exists between pulse width (PW) and frequency (F) in this frequency range at which SCS patients experience significant reduction in symptoms such as back pain.

  • Patent number: 10653885
    Abstract: A system for a neurostimulator coupled to electrodes, and a method of providing therapy to a patient using the electrodes implanted within the patient. A target multipole relative to the electrodes is defined. The target multipole is emulated by defining an initial electrical current distribution for the electrodes, such that a first set of active electrodes respectively has electrical current values of a first polarity. Each of the electrical current values of the first polarity is compared to a first threshold value, and at least one of the electrodes in the first active electrode set is zeroed-out based on the comparison. The electrical current value of each of the zeroed-out electrode(s) is redistributed to remaining ones of the electrodes to define a new electrical current distribution for the electrodes. Electrical current is conveyed to the electrodes in accordance with the new electrical current distribution, thereby providing the therapy.

  • Publication number: 20200147391
    Abstract: A neuromodulation system for use with electrodes to modulate a volume of neural tissue may include a waveform generator and a controller. The waveform generator may be configured to be electrically connected to the electrodes and provide an electrical waveform through at least some of the electrodes to provide a neuromodulation therapy. The controller may be configured to use a program to control the waveform generator to deliver a neuromodulation therapy by delivering both a fast-acting sub-perception neuromodulation and a slow-acting sub-perception neuromodulation. The fast-acting neuromodulation has a wash-in transition period less than a first time duration, and the slow-acting sub-perception neuromodulation has a wash-in transition period more than a second time duration, the second time duration being longer than the first time duration.

  • Publication number: 20200147390
    Abstract: New waveforms for use in an implantable pulse generator or external trial stimulator are disclosed which mimic actively-driven biphasic pulses, and which are particularly useful for providing sub-perception Spinal Cord Stimulation therapy using low frequency pulses. The waveforms comprise anodic and cathodic pulses which are effectively monophasic in nature, although low-level, non-therapeutic charge recovery can also be used.

Embodiments of the system include an implantable stimulator and an external controller configured to control the implantable stimulator. A clinician can prescribe a set amount of stimulation therapy to a patient. The external controller is programmed with the prescription.

  • Publication number: 20200061380
    Abstract: Disclosed are systems and methods for providing stimulation using waveforms with long duration phases in a spinal cord stimulator. Simulation shows the effectiveness of using phase durations of greater than 2.0 ms, or even 2.6 ms or greater, in recruiting inhibitory interneurons in the dorsal horn of the spinal cord, or in recruiting dorsal column axons of the dorsal column, both of which promote pain suppression in spinal cord stimulation (SCS) patients. Traditional SCS devices may not allow the programming of phase durations of such lengths, and so examples of how long phase durations can be effectively created is shown by way of a non-limiting example, preferably in a single timing channel. The waveforms preferably have at least two phases of opposite polarities, at least one of which is long, although phases may be split into sub-phases. The waveforms may be charge balanced at each electrode.

    Abstract: A method is disclosed for programming a patient's stimulator device using an external device. The method obtains information such as a model at the external device, wherein the information is specific to the patient, wherein the information comprises a range or volume of stimulation parameters determined based on testing of the patient that preferably provide sub-perception therapy; and providing from the external device instructions for execution at the stimulator device, the instructions specifying an amplitude, a pulse width, and a frequency of stimulation pulses to be provided at one of more of electrodes in an electrode array of the patient's stimulator device, wherein the instructions vary over time at least one of the amplitude, pulse width, and frequency within the range or volume. Varying at least one of these parameters helps in preventing the patient's neural tissue from become habituated when compared to stimulation that is provided without variance.
