North Shore-LIJ Health System officials said Friday that researchers at the Feinstein Institute in Manhasset have received a federal patent for a device that could help monitor traumatic brain injuries sustained in combat.

Feinstein officials and researchers at the University of Cincinnati received a $5 million grant from the U.S. Department of Defense in 2010 to develop the device, which health system officials call the “smart sensor” for its ability to improve the conditions of veterans severely injured in battle.

“This U.S. patent approval is a major step forward towards the improved monitoring of patients suffering from severe brain injury,” said Dr. Raj K. Narayan, the chair of neurosurgery at North Shore University Hospital and Long Island Jewish Medical center who alongside researcher Chunyan Li and colleagues at the University of Cincinnati helped develop the device.

Officials said that unlike other tools that measure intracranial pressure and brain oxygen levels, the smart sensor will monitor changes within the brain that are often more difficult to track.

Narayan said the smart sensor’s catheter system is packed with multiple miniaturized sensors allowing for the continuous monitoring of biochemical and physiological parameters in real time, like brain glucose, blood flow, temperature, and electrical activity.

“This information can be critically important in deciding how to treat TBI patients,” Narayan said. “The more information the neurocritical care team has, the better we can help patients recover.”

Officials said the smart sensor is still in the developmental phase and should be ready for clinical use in three or four years.
