The Vivistim Pre-Service Clearance Program is designed to support patients and their provider’s office in navigating the insurance process. Our program assists with securing prior authorization or pre-certification, ensuring that all necessary approvals are obtained before the start of Vivistim Therapy. This service helps to streamline the prior authorization process, minimize delays, and provide peace of mind to both patients and healthcare providers.

Paired Vagus Nerve Stimulation for Stroke Bibliography
The following bibliography is a list of peer-reviewed publications related to the clinical use of Paired VNS for the treatment of chronic stroke and its mechanisms of action. This bibliography is not intended to be a comprehensive list of every publication on the subject. This list does not include applications for Paired VNS that have been studied outside of stroke except where mechanism of action may overlap. The bibliography was compiled through PubMed and provides links to the journal articles referenced. Book chapters, abstracts, and posters are not included.
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.
