    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： Tissue stimulation systems generally include a pulse generating device for generating electrical stimulation pulses, at least one implanted electrode for delivering the electrical stimulation pulses generated by the pulse generating device, and a programmer capable of communicating with the pulse generating device. Stimulation pulses may be defined by several parameters, such as pulse width and amplitude. In methods of stimulating the tissue with the stimulation system, a user may adjust one of the parameters such as pulse width. The programmer may automatically adjust the pulse amplitude in response to the change in pulse width in order to maintain a substantially constant effect of the stimulation pulses.

    摘要： A method for treating a patient having discogenic pain includes implanting a neurostimulation lead within an anterior portion of the epidural space adjacent to the posterior longitudinal ligament. A plurality of electrodes is attached to the lead and the lead is implanted with at least a portion of the electrodes facing the posterior longitudinal ligament. The lead may be implanted in the lumbar region of the patient's spine, posterior and parallel to the posterior longitudinal ligament. Electrical stimulation energy applied to the patient through the electrode lead implanted in this manner inhibits the pain signals traveling within the posterior longitudinal ligament. Thus, the applied electrical stimulation energy has an anesthetic effect on the pain fibers adjacent to the posterior longitudinal ligament.

    摘要： A method for using spinal cord stimulation to treat symptoms of motor disorders includes implanting a stimulation lead within a ventral portion of the epidural space. The lead is implanted with at least a portion of the electrodes facing the spinal cord. In a method for providing therapy to a patient suffering from a motor disorder, electrical stimulation energy is applied to at least one ventral column nerve fiber through the implanted stimulation lead. A peripheral region of the patient's body exhibits the symptoms of the motor disorder, and the ventral column nerve fiber to which the stimulation is applied innervates that peripheral region.
