Two Neurosurgically Implanted Devices Recently Approved YORK, Pa., Jan. 20 /PRNewswire/ -- The U.S. Food and Drug Administration recently approved two neurosurgically implanted devices. For Parkinson's Disease and essential tremor, Activa Tremor Control Therapy utilizes mild electrical stimulation to block the brain signals that cause tremor. The therapy stimulates target nuclei in the thalamus via an insulated wire lead with electrodes that are surgically implanted to the brain and connected to a pulse generator. For epilepsy, the NeuroCybenetic Prosthesis (NCP) System is used for the treatment of medically refractory partial onset seizures. The NCP consists of a generator and a nerve stimulator electrode which transmits antiepileptic electrical signals to the brain through the vagus nerve. It is indicated as an adjunctive treatment for adults and adolescents over 12 years of age. These interventional therapies are now available at York (Pa.) Hospital through York Neurosurgical Associates. SOURCE York Health System CONTACT: Barry Sparks of York Health System, 717-851-3151 ©1997 PR Newswire. All rights reserved.
