  • Publication number: 20210228881
    Abstract: The present technology provides systems and methods for directly suppressing nerve cells by delivering electrical stimulation having relatively long pulse widths and at amplitudes below an activation threshold of the nerve cells. For example, some embodiments include delivering a therapy signal having individual pulses with pulse widths of between about 5 ms and 100 ms. Directly suppressing the nerve cells is expected to reduce the transmission of pain signals.

  • Patent number: 11064898
    Abstract: A method for implanting a neurostimulation lead within a patient includes measuring impedances of electrodes on the lead in order to correctly position the lead relative to a target tissue region. The electrodes are circumferentially segmented electrodes that are spaced from each other about the longitudinal axis of the lead. When the difference between the impedances of the electrodes exceeds a threshold value, the lead is in the correct position. In accordance with another embodiment, impedance measurements are used to select which one of the electrodes is closest to the target tissue region. By determining which electrode has the highest impedance and which electrode has the lowest impedance, the type of tissue adjacent to each electrode can be determined based on the conductivity properties of the tissue. The target tissue region may be a spinal cord, a posterior longitudinal ligament, white matter, or gray matter.

  • Patent number: 10780276
    Abstract: Systems and methods for selecting low-power, effective signal delivery parameters for an implanted pulse generator are disclosed. A representative system includes a signal generator and a computer-readable medium that, for first and second signals, increases and decreases an amplitude of the signal over multiple steps from a baseline amplitude at which the patient has a baseline response. At individual step increases and decreases, the system receives a pain score based on the patient's response. The instructions compare the pain scores for the two signals and determine one of the signals for additional therapy to the patient, based on the pain scores and an expected energy consumption of the signals.

  • Publication number: 20200023188
    Abstract: Tissue stimulation systems generally include a pulse generating device for generating electrical stimulation pulses, at least one implanted electrode for delivering the electrical stimulation pulses generated by the pulse generating device, and a programmer capable of communicating with the pulse generating device. Stimulation pulses may be defined by several parameters, such as pulse width and amplitude. In methods of stimulating the tissue with the stimulation system, a user may adjust one of the parameters such as pulse width. The programmer may automatically adjust the pulse amplitude in response to the change in pulse width in order to maintain a substantially constant effect of the stimulation pulses.

  • Patent number: 10537741
    Abstract: A method of selecting a subset of electrodes in a stimulator device implanted in a patient for further clinical evaluation is disclosed. The method comprises measuring at least first and second measurement for each of the plurality of electrodes that are indicative of the ability of the electrode if activated to provide useful therapy to the patient in which the stimulator device is implanted A weight is then determined for each of the measurements. The weight is then applied to each electrode measurement, which measurement may be normalized, and the weighted measurements for each electrode are preferably summed to arrive at a value which itself is indicative of a particular electrode's ability to provide useful therapy to the patient. These values can then be used to determine a subset of the electrodes useful for further clinical evaluation in the patient, which improved the accuracy and speeding determining appropriate patient therapy.
