    摘要: A method and external control device for providing therapy to a patient using first and second electrodes implanted within the patient is provided. A train of electrical multi-phasic pulses is generated. A first electrical current is sourced from the second electrode and at least a portion of the first electrical current is sunk to the first electrode during a stimulation phase of each multi-phasic pulse, thereby therapeutically stimulating a first tissue region adjacent the first electrode. A second electrical current is sourced from the first electrode and at least a portion of the second electrical current is sunk to the second electrode during a charge recovery phase of each multi-phasic pulse, thereby recovering at least a portion of the charge that had been injected into the patient during the stimulation phase of each multi-phasic pulse, and therapeutically stimulating a second tissue region adjacent the second electrode.

    摘要: A method and neurostimulator for providing therapy to a patient is provided. In one technique, an electrical pulsed waveform is conveyed between a caudal electrode and spinal cord tissue, thereby evoking action potentials that are orthodromically propagated along dorsal column fibers and evoking action potentials that are antidromically propagated along the DC fibers. Electrical energy is conveyed between a rostral electrode and the spinal cord tissue, thereby modulating times that the action potentials orthodromically propagated along the DC fibers arrive at the brain. In another technique, an electrical pulsed waveform is conveyed through a first electrode, thereby evoking action potentials that are propagated along a neural axon, and electrical energy is conveyed through the second electrode. The electrical energy has a frequency that is greater than a pulse rate of the electrical pulsed waveform, such that the action potentials propagated along the neural axon are blocked by the electrical energy.

    摘要: 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.

    摘要: A method of providing therapy to a patient having a disorder using an electrode located adjacent a peripheral target neural region. The method comprises conveying electrical stimulation energy from the electrode that stimulates a first set of nerve endings in the peripheral target neural region. The method further comprises increasing an activation threshold of a second set of nerve endings in the peripheral target neural region, thereby rendering the second set of nerve endings less excitable to the electrical stimulation energy. The first set of nerve endings are relatively far from the electrode and the second set of nerve endings are relatively near the electrode.

The system comprises a user-controlled input device configured for generating control signals, and at least one processor configured for generating a plurality of stimulation parameter sets in response to the control signals that, when applied to the electrodes, will shift electrical current between electrodes to modify a region of tissue activation. The processor(s) is further configured for computing an estimate of the region of tissue activation, and for generating display signals capable of prompting a monitor to display an animated graphical representation of the computed estimate of the region of tissue activation.
