The MicroTransponder® Vivistim® Paired VNS™ System is intended to be used to stimulate the vagus nerve during rehabilitation therapy in order to reduce upper extremity motor deficits and improve motor function in chronic ischemic stroke patients with moderate to severe arm impairment. Do not use if you have had a bilateral or left cervical vagotomy. Risks may include, but are not limited to pain after surgery, hoarseness, bruising, swelling, coughing and throat irritation. Infection leading to explant is a risk associated with any device surgery. For full safety information, please see Instructions for Use and our Safety Information. Individual results may vary.
