FDA approves device intended to reduce traumatic brain injuries

By the numbers: The National Institute of Neurological Disorders and Stroke estimates there are between 1.6 million and 3.8 million sports- and recreation-related TBIs in the country each year.

How it works: The Q-Collar, authorized for athletes 13 and older, adds compressive force to the jugular veins when worn around the neck.

• The force increases the blood volume in the skull’s blood vessels, creating a tighter fit of the brain inside the skull.
• That reduces the brain's ability to move unrestrained in the skull, which may protect the organ from the effects of head impacts, the FDA said.

What they're saying: “Today’s action provides an additional piece of protective equipment athletes can wear when playing sports to help protect their brains from the effects of repetitive head impacts while still wearing the personal protective equipment associated with the sport,” said Christopher Loftus, acting director of the FDA's Office of Neurological and Physical Medicine Devices.
