Methods and systems for stimulating a motor cortex of the brain to treat a medical condition
Methods of treating a medical condition include applying at least one stimulus to a motor cortex within a brain of a patient with an implanted system control unit in accordance with one or more stimulation parameters. Systems for treating a medical condition include a system control unit implanted within the patient that is configured to apply at least one stimulus to a motor cortex within a brain of a patient in accordance with one or more stimulation parameters.
1. A method of treating a patient with a medical condition, comprising
implanting a microstimulator within an opening extending completely through a skull of said patient, wherein the microstimulator resides within the opening, wherein said microstimulator comprises a capsule, and one or both of electrical circuitry and a drug pump contained within said capsule;
generating a stimulus in accordance with one or more stimulation parameters using said microstimulator; and
applying said stimulus to a portion of a motor cortex of said patient adjacent said opening, thereby treating said medical condition, wherein sad microstimulator comprises the electrical circuitry contained within said capsule, and a stimulation electrode disposed on an external surface of said capsule, wherein said stimulus is extradurally applied to said motor cortex
and wherein said microstimulator comprises an indifferent electrode disposed on said external surface of said capsule, and said microstimulator is implanted within said opening, such that said stimulation electrode is adjacent said motor cortex and said indifferent electrode is adjacent an outer surface of said skull.
