Abstract: An implantable cranial medical device includes a housing configured to be positioned on a skull of a subject such that at least a portion of the housing covers a burr hole of the skull. The medical device also includes a brain catheter connector extending from the housing and configured to extend within the skull. The brain catheter connector includes a first connector and a second connector. The second connector extends farther away from the housing than the first connector. Additionally, the medical device includes a first fluid path extending through the housing and the first connector, and a second fluid path extending through the housing and the second connector. The first and second fluid paths are not in fluid communication with one another within the housing.
