The latest patent filing from Cranius LLC describes a reservoir for its implanted drug delivery devices which is shaped and formed to empty and fill reliably without any concern for neighboring organ impingement or compression, and which can precisely control and monitor exactly just how much of a medicine is being delivered.

Recent years have seen progress in treating brain disease, but one major challenge remains: getting therapeutic treatments across the blood-brain barrier. Now, Cranius LLC has raised $19.4 million to advance a device designed to bypass the blood-brain barrier and deliver medicines directly and continuously to the brain.
