Abstract
A cranial bolt secured to a skull of a patient includes a threaded portion and a lumen portion. Threaded portion has an inner surface forming a central passageway which extends throughout the threaded portion. The inner surface includes a connector mating with the lumen portion. The lumen portion includes a stem portion that enters the central passageway and engages the mating connector. A fluid tight seal is formed between the inner surface of the threaded portion and the stem portion. At least two lumens are disposed through the stem portion and the base portion. The lumens have a proximal end opening outside the skull and a distal end opening inside the skull. One embodiment includes sensor lumens diverging from the centerline and another allows the lumen portion to rotate independent of the threaded portion.
