DALLAS (1080 KRLD) - The University of Texas at Dallas is developing a new device to help stroke victims.

The wireless device is a tiny piece of glass that sits on the vagus nerve in the neck. It helps release chemicals in the brain that can help the person recover faster.

Dr. Robert Rennaker, professor of engineering and neuroscience and the Texas Instruments Distinguished Chair in Bioengineering, helped create the device.

Dr. Rennaker says, "You get about a three to four times improvement in recovery with this device. While you are doing rehabilitation, we are stimulating the nerve at very specific points."

He says around 150 patients have tried it.

A $1.4 million grant will be used from the National Institutes of Health for final testing of the device before it goes to the Food and Drug Administration for approval.
