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.

Abstract: At least one system and at least one method permit a clinician to view or hear power consumption data during a Spinal Cord Stimulation (SCS) system fitting procedure. For example, a clinician's programming computer includes a display of power consumption for each effective stimulation configuration under evaluation during fitting. A clinician performing the fitting procedure uses a programming computer to select various stimulation configurations. The power consumption of the SCS configuration(s) presently and/or previously exercised is displayed for the clinician. By comparing the power consumption for each configuration, the clinician may select a configuration consuming less power while providing effective therapy. Suggestions for low power configurations may be provided by the programming computer.

Abstract: A neural stimulation system automatically corrects or adjusts the stimulus magnitude in order to maintain a comfortable and effective stimulation therapy. Auto correction of the stimulus magnitude is linked to the measurement of pressure in the vicinity of the electrode-tissue interface. Because the pressure near the electrode-tissue interface can provide a measure of the electrode contacts' proximity to the neural tissue, and hence quantity of electrical energy delivered to the neural tissue, a change in the measured pressure or pressure morphology indicates that the stimulation energy may need to be adjusted. Hence, changes in pressure provide a feedback mechanism that permit the system to effectively auto correct the stimulus amplitude in order to maintain a desired therapeutic effect.

Abstract: 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 bi-directional 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.
