A method and implantable medical device system capable of being anchored in a head or spinal cord of a patient. During implant, the dura of the patient is partially removed and the medical device component is placed on one side of the dura. The medical device component contains one or more anchors that mate with one or more nuts placed on the other side of the dura. The medical device component is thereby attached to the dura in a substantially fixed position relative to the head or spinal cord.
