Researchers at the Massachusetts Institute of Technology are developing a pump to deliver drugs directly to the brain. The team’s pump prototype is attached to a needle, enabling targeted drug delivery. The main researcher focused his efforts on keeping the pump’s multiple parts as static as possible. At the heart of the team’s design strategy is an attempt to make the drug pump as small as possible. The lab hopes that eventually their technology could be used to diagnose and treat brain disorders, like anxiety and depression.
