Treating inflammation, chronic pain and other disorders with neuromodulation
Some implementations provide a method of treating chronic pain or inflammation with neural modulation, the method including: placing a surgical instrument to reach into a torso section of a patient's body, the patient suffering from chronic pain or inflammation in a primary area in the torso section; placing a wireless device into an opening on the surgical instrument, the wireless device suitable to fit into the opening and configured to receive electromagnetic energy non-inductively from a source located outside the patient's body; through the opening on the surgical instrument, positioning the wireless electrode lead adjacent to or near excitable tissue in the primary area in the torso section of the patient; and causing electrical pulses to be delivered to one or more electrodes on the wireless device such that neural modulation is applied to the excitable tissue in the primary area in the torso section.
