    Publication number: 20150217113
    Abstract: Systems and methods for managing pain in a patient using an electrical waveform that link the modulation of a waveform parameter for different areas of a patient. One embodiment in a system for managing pain in a patient comprises an electric device configured to be implanted into the patient and including a plurality of electrodes having at least a first electrode associated with a first area of the patient and a second electrode associated with a second area of the patient. The system further includes an implantable device configured to be coupled to the electrode device and having a computer-operable medium programmed to change the waveform parameter applied to the first electrode and automatically set the waveform parameter applied to the second electrode based on a relationship between a first therapy range and a second therapy range of the waveform parameter.

  • Systems and methods for adjusting electrical therapy based on impedance changes
    Patent number: 9061154
    Abstract: System and methods for adjusting electrical therapy based on impedance changes are disclosed herein. A method in accordance with a particular embodiment includes applying a therapeutic electrical signal to a patient via an implanted portion of a patient stimulation system that includes a signal delivery device in electrical communication with a target neural population of the patient. The electrical signal is delivered in accordance with a signal delivery parameter having a first value. Using the implanted portion of the patient stimulation system, a change in an impedance of an electrical circuit that includes the signal delivery device is detected. Based at least in part on the detected impedance change, the method can further include automatically adjusting the value of the signal delivery parameter from the first value to a second value different from the first, without human intervention.

  • SELECTIVE HIGH FREQUENCY SPINAL CORD MODULATION FOR INHIBITING PAIN WITH REDUCED SIDE EFFECTS, AND ASSOCIATED SYSTEMS AND METHODS
    Publication number: 20150142076
    Abstract: Selective high-frequency spinal chord modulation for inhibiting pain with reduced side affects and associated systems and methods are disclosed. In particular embodiments, high-frequency modulation in the range of from about 1.5 KHz to about 50 KHz may be applied to the patient's spinal chord region to address low back pain without creating unwanted sensory and/or motor side affects. In other embodiments, modulation in accordance with similar parameters can be applied to other spinal or peripheral locations to address other indications.

  • SYSTEMS AND METHODS FOR PRODUCING ASYNCHRONOUS NEURAL RESPONSES TO TREAT PAIN AND/OR OTHER PATIENT CONDITIONS
    Publication number: 20150105839
    Abstract: Systems and methods for producing asynchronous neural responses to treat pain and/or other patient conditions are disclosed. A method in accordance with a particular embodiment includes selecting a target stimulation frequency that is above a threshold frequency, with the threshold frequency corresponding to a refractory period for neurons of a target sensory neural population. The method can further include producing a patient sensation of paresthesia by directing an electrical signal to multiple sensory neurons of the target sensory neural population at the stimulation frequency, with individual neurons of the sensory neural population completing corresponding individual refractory periods at different times, resulting in an asynchronous sensory neuron response to the electrical signal.
