Current management system for a stimulation output stage of an implantable neurostimulation system

摘要: A current management system for use in the stimulation output stage of a neurostimulation can be programmed to steer different amounts through electrodes vary how strongly tissue adjacent each electrode is stimulated during particular episode. An drive circuit associated with that available allows independent control flow electrode. reference provided source or sink as necessary balance currents going into and out patient, so no required serve purpose. More specifically, by configuring maintain constant potential at (e.g., approximately half way between top bottom voltage rail), will cause net patient equal flowing thus satisfying Kirchhoff's law.
