A stroke rehabilitation method invented at the University of Texas at Dallas recently received approval from the Food and Drug Administration. The system that treats chronic ischemic stroke survivors is the first of its kind, according to a UT Dallas press release. Most strokes (87%) are ischemic strokes, which are often caused by blood clots, according to the Centers for Disease Control and Prevention. An ischemic stroke happens when blood flow through the artery that supplies oxygen-filled blood to the brain becomes blocked. Read more

IT BEGAN IN early October 2017, when 108 stroke patients with significant arm and hand disabilities turned up for a peculiar clinical trial. The researchers would be surgically implanting a neurostimulator to their vagus nerve, the cranial nerve that runs along the groove in the front of the neck and is responsible for transmitting signals from the brain to other parts of the body. By the time the trial concluded, the subjects’ once limited limbs had begun to come back to life. Somehow, pulses to that nerve combined with rehab therapy had given the patients improved use of their disabled limb—and done so faster and more effectively than any treatment before it, even on those who had responded to nothing else.

For the 7 million American survivors of stroke, increasing the effectiveness of physical rehabilitation for mobility and motor skills could provide a transformative boost in quality of life.
Researchers from The University of Texas at Dallas’ Texas Biomedical Device Center (TxBDC) conceived a therapy to rewire circuits in the brain involving vagus nerve stimulation (VNS) more than a decade ago, and scientists have since been refining the technique to treat a variety of disorders, including stroke. On Aug. 27, the Food and Drug Administration (FDA) approved the rehabilitation system for chronic ischemic stroke survivors — the first such treatment of its kind. Read more

In August 2021, the MicroTransponder Vivistim Paired Vagus Nerve Stimulation (VNS) System was approved by the FDA for the treatment of moderate to severe upper extremity motor deficits associated with chronic ischemic stroke. Seth Hays, PhD, The University of Texas at Dallas, Dallas, TX, discusses the clinical trial data that led to the approval of the Vivistim System, a first of its kind, drug-free rehabilitation device.

The U.S. Food and Drug Administration today approved the MicroTransponder Vivistim Paired VNS System (Vivistim System), a first-of-its-kind, drug-free rehabilitation system intended to treat moderate to severe upper extremity motor deficits associated with chronic ischemic stroke—a stroke caused by a blockage of blood flow to the brain with long-lasting symptoms—using vagus nerve stimulation (VNS).

Collin County personnel asked UT Dallas officials about the possibility of lending a freezer. The Texas Biomedical Device Center at UT Dallas was able to assist. “The Texas Biomedical Device Center was founded by a U.S. Marine and an Eagle Scout, so service to our community comes naturally. We are happy to have had the opportunity to serve by sharing our equipment during this crisis,” said Dr. Michael Kilgard, the Margaret Fonde Jonsson Professor of neuroscience and interim executive director and chief science officer at the Texas Biomedical Device Center.

The Texas Biomedical Device Center (TxBDC) at The University of Texas at Dallas received FDA approval to proceed with two studies using the ReStore Vagus Nerve Stimulator. The first study will use ReStore to enhance recovery following a spinal cord injury. The second study will use ReStore to enhance prolonged exposure therapy for treating Post Traumatic Stress Disorder (PTSD). Read more
