Abstract
An implantable medical device having an hermetically sealed enclosure housing electrical and electronic circuitry and a battery for powering such circuitry is connected to an intracranial lead or pigtail which measures or senses intracranial physiologic signals such as intracranial fluid pressure and/or temperature. The implantable medical device is preferably implanted subcutaneously beneath a patient's skin and telemeters stored data or real-time-sensed data to an external device which may be configured to combine barometric pressure data with intracranial pressure data to derive intracranial gage pressure. The implantable medical device and its associated lead reduce the risk of intracranial infections.
