NeuroStar TMS Therapy® is currently under review by the United States Food and Drug Administration (FDA) and is pending market clearance for the treatment of major depression. The NeuroStar TMS Therapy System® uses highly focused, very short, repetitive pulses of magnetic energy to penetrate the skull and stimulate nerve cells in brain regions believed to be linked to depression. NeuroStar TMS Therapy® is non-invasive and the amount of electricity generated in the brain cannot be felt so the patient does not require anesthesia or sedation and can resume normal activities immediately after treatment.
