SYSTEM AND METHOD FOR CONTROLLING THE PROPAGATION DIRECTION OF ELECTRICAL STIMULATION ALONG A NERVE FIBER

摘要

A system and method for neuromodulation is provided. The system includes two or more microparticles implantable in a series along the length of a nerve fiber, and a central controller that is operatively coupled to the two or more microparticles. The central controller is configured to instruct at least one of the microparticles to deliver an electrical impulse to the nerve fiber to stimulate it. Each of the microparticles includes either a stimulation electrode configured to deliver the electrical impulse to the nerve fiber, or a sensor configured to monitor neural activity. In some implementations, at least one of the microparticles includes a stimulation electrode and a sensor. The central controller includes a power system configured to wirelessly deliver power to the microparticles, and a processing system configured to provide stimulation parameters to the microparticles that stimulate the nerve fiber. In some implementations, the processing system is configured to process any sensed neural activity and update the stimulation parameters accordingly.
