About Micro Transponder

Micro Transponder, Inc. is dedicated to transforming the lives of stroke survivors through its innovative neurostimulation technology. The company's flagship product, the FDA‑approved Vivistim® Paired VNS™ System, enhances stroke rehabilitation by pairing vagus nerve stimulation (VNS) with physical and occupational therapy. This approach leverages the brain's neuroplasticity to improve upper limb function, offering new hope to those with chronic arm and hand impairments following an ischemic stroke.

By integrating this therapy into rehabilitation programs, Micro Transponder aims to help stroke survivors regain independence in daily activities and enhance their quality of life. The company's commitment to advancing stroke recovery is evident in its ongoing research and collaboration with healthcare providers to make this therapy accessible to more patients.
