  • Patent number: 10413729
    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. In particular embodiments, aspects of the foregoing modulation therapies may be implemented by systems and devices that have simplified functionalities.

  • Patent number: 7853330
    Abstract: A method for determining whether the relative position of electrodes used by a neurostimulation system has changed within a patient comprises determining the amplitude of a field potential at each of at least one of the electrodes, determining if a change in each of the determined electric field amplitudes has occurred, and analyzing the change in each of the determined electric field amplitudes to determine whether a change in the relative position of the electrodes has occurred. Another method comprises measuring a first monopolar impedance between a first electrode and a reference electrode, measuring a second monopolar impedance between second electrode and the reference electrode, measuring a bipolar impedance between the first and second electrodes, and estimating an amplitude of a field potential at the second electrode based on the first and second monopolar impedances and the bipolar impedance.

  • Publication number: 20080021513
    Abstract: A system and method for rapidly switching stimulation parameters of a Spinal Cord Stimulation (SCS) system increases the number of stimulation parameter sets that may be tested during a fitting procedure, or alternatively, reduces the time required for the fitting procedure. The switching method comprises selecting a new stimulation parameter set, and setting the initial stimulation levels to levels at or just below an estimated perception threshold of the patient. The estimated perception level is based on previous stimulation results. The stimulation level is then increased to determine a minimum stimulation level for effective stimulation, and/or an optimal stimulation level, and/or a maximum stimulation level, based on patient perception.

  • Publication number: 20070293914
    Abstract: The invention is a system and method for detecting the status of a rechargeable battery included within an implantable medical device. The medical device can incorporate a status indicator which signals the user concerning the battery status, e.g., low battery level. The signal may be audible or it may arise from an electrical stimulation that is perceptually distinguished from the operative, therapeutic stimulation. The external programmer may also incorporate a second battery status indicator that is visual, audible, or physically felt. Battery status data may be conveyed on visual displays on the external programmer by uploading this information from the medical device using a bidirectional telemetry link. Such battery status data are helpful to the user to indicate when the battery should be recharged and to the clinician to monitor patient compliance and to determine end-of-useful life of the rechargeable battery.

  • Publication number: 20070265679
    Abstract: A method for selecting Spinal Cord Stimulation (SCS) stimulation parameter sets guides a clinician towards an effective set of stimulation parameters. The clinician first evaluates the effectiveness of a small number of trial stimulation parameters sets from a Measurement Table comprising for example, four stimulation parameter sets. Based on the patient's assessment, the trial stimulation parameter sets are ranked. Then the clinician selects a starting or benchmark row in a Steering Table corresponding to the highest ranked trial stimulation parameter set. The clinician moves either up or down form the starting row, testing consecutive parameter sets. The clinician continues as long as the patient indicates that the stimulation results are improving. When a local optimum is found, the clinician returns to the benchmark row, and tests in the opposite direction for another local optimum. If an acceptable set of stimulation parameters is found, the selection process is complete.

  • Publication number: 20070208394
    Abstract: A neural stimulation system automatically corrects or adjusts the stimulus magnitude (stimulation energy) in order to maintain a comfortable and effective stimulation therapy. Because the changes in impedance associated with the electrode-tissue interface can indicate obstruction of current flow and positional lead displacement, lead impedance can indicate the quantity of electrical stimulation energy that should be delivered to the target neural tissue to provide corrective adjustment. Hence, a change in impedance or morphology of an impedance curve may be used in a feedback loop to indicate that the stimulation energy needs to be adjusted and the system can effectively auto correct the magnitude of stimulation energy to maintain a desired therapeutic effect.

  • Publication number: 20060241722
    Abstract: A tissue stimulation system is provided that evaluates and/or scores stimulation sets based on both patient feedback and frequency of use. Stimulation sets and any associated scores and/or usage may be stored in a retrievable database. Upon subsequent stimulation sessions, a patient may select stimulation sets that have a high score and/or usage in order to effectively meet therapeutic objectives. Methods of determining patient satisfaction, which involve evaluating patient pain before and after stimulation pulses are applied, are also provided herein.

  • Publication number: 20060122654
    Abstract: Interelectrode impedance or electric field potential measurements are used to determine the relative orientation of one lead to other leads in the spinal column or other body/tissue location. Interelectrode impedance is determined by measuring impedance vectors. The value of the impedance vector is due primarily to the electrode-electrolyte interface, and the bulk impedance between the electrodes. The bulk impedance between the electrodes is, in turn, made up of (1) the impedance of the tissue adjacent to the electrodes, and (2) the impedance of the tissue between the electrodes. In one embodiment, the present invention makes both monopolar and bipolar impedance measurements, and then corrects the bipolar impedance measurements using the monopolar measurements to eliminate the effect of the impedance of the tissue adjacent the electrodes. The orientation and position of the leads may be inferred from the relative minima of the corrected bipolar impedance values.

  • Publication number: 20060036286
    Abstract: An implantable system control unit (SCU) includes means for measuring tissue impedance or other condition to determine allograft health, in order to predict or detect allograft rejection. The SCU also includes at least two electrodes coupled to means for delivering electrical stimulation to a patient within whom the device is implanted, and may also include a reservoir for holding one or more drugs and a driver means for delivering the drug(s) to the patient. In certain embodiments, the system is capable of open- and closed-loop operation. In closed-loop operation, at least one SCU includes a sensor, and the sensed condition is used to adjust stimulation parameters. Alternatively, this sensory “SCU” sounds an alarm, communicates an alarm to an external device, and/or is responsive to queries regarding sensed information, such as tissue impedance.

  • Publication number: 20050209655
    Abstract: Methods for selecting stimulation parameter sets guide a clinician towards an effective set(s) of stimulation parameters. The clinician first evaluates the effectiveness of a small number of trial stimulation parameters sets from a Measurement Table comprising for example, four stimulation parameter sets, measuring the perception threshold and maximum threshold levels. The maximum comfortable step size and desired field shift resolution are determined, and are used along with the measured threshold levels to determine an appropriate step size to use in the current steering process. In order to maintain paresthesia at a relatively constant level during the steering process, a Superposition Equalization (SEQ) algorithm is used to compensate for the physical characteristics of the lead array, i.e., electrode separation and size. A multiplier is determined and a modifying function is used to apply this multiplier to the electrode energy output during transition to maintain a relatively constant current density.
