摘要： A tissue stimulation system and computer software and method of operating the system is provided. An array of electrodes is placed contact with tissue of a patient (e.g., neural tissue), and electrical current is conveyed within the electrode array, thereby creating a stimulation region in the tissue. Electrical current is shifted between cathodes of the electrode array in incremental steps over a range, thereby causing displacement of the stimulation region at substantially uniform distances over the incremental steps. The electrical current may be shifted between the cathodes in accordance with a sigmoid-like function of a position of the stimulation region. A navigation table containing a series of states and corresponding gradually and non-uniformly changing electrical current values can be accessed, in which case, the electrical current may be shifted between the cathodes by incrementing through the states of the navigation table.

摘要： A tissue stimulation system and computer software and method of monitoring a neurostimulation lead having a plurality of electrodes implanted within a patient (e.g., adjacent the spinal cord) is provided. Neurostimulation lead models are provided, each of which includes estimated electrical parameter data (e.g., electrical field potential data) corresponding to a predetermined position of the neurostimulation lead. Electrical energy is transmitted to or from the electrodes, and electrical parameter data (e.g., electrical field potential data) is measured in response to the transmitted electrical energy. The measured electrical parameter data is compared with the estimated electrical parameter data of each of the neurostimulation lead models, and a position of the neurostimulation lead is determined based on the comparison.

摘要： 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.

摘要： Neurostimulators and methods of using neurostimulators are provided. The neurostimulator is implanted within a tissue pocket of a patient, and electrical energy is conveyed from the neurostimulator to stimulate a target tissue site remote from the tissue pocket. The neurostimulator has a case with which one or more electrodes are associated. The electrical energy is returned to the electrode(s) in a manner that prevents, or at least reduces, pocket stimulation that may otherwise occur due to the return of electrical energy to the case of the neurostimulator.
