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.

Abstract: An apparatus for fixing a cardiac lead in place within the vasculature of the heart includes a coil having a normal helical shape and a stylet for holding the coil straight during insertion of the coil through a lumen of the lead. Upon retraction of the stylet, the coil returns to its helical shape along with the lead, forcing portions of the lead into contact with the vessel wall.
