Ultrasound Implant Safely Opens Blood–Brain Barrier


The cells lining blood vessels in the brain form tight, tough-to-penetrate junctions that prevent toxic molecules from slipping into the brain.

Unfortunately, this blood-brain barrier also blocks cancer drugs from reaching tumor cells in the brain, creating a significant drug-delivery problem.

Now, preliminary results from a Phase I/II clinical trial suggest that a small implant that emits ultrasound waves can safely open the blood-brain barrier in people, potentially allowing drugs in.
