N2 - Intracranial pressure (ICP) is the pressure exerted by the components of the cranial vault, which are the brain, cerebrospinal fluid (CSF), and blood. An elevation of ICP results in a reduction of blood flow to the brain [1]. The brain can cope with intracranial hypertension (ICH) to a certain extent, after which a slight increase in the cerebral volume results in a rapid rise of ICP [2]. A significant reason for death and long-term disability due to head injuries and pathological conditions is an elevation in ICP. An ICP > 20 mmHg is considered a significant threshold and demands an immediate control measure [3]. ICP monitoring can assist in the management of patients with a variety of brain diseases and injuries. The technique has proven valuable, indeed often lifesaving, in the acute care of traumatic brain injury (TBI) [4], hydrocephalus [5], drowning [6], inflammatory and related cerebral diseases such as Reye's syndrome [7], intracranial hemorrhage [8], and postoperative suboccipital brain tumors [9]. Most patients have headaches and other symptoms suggestive (but not always indicative) of raised ICP; continuous access to ICP levels would greatly facilitate their management. There is a conspicuous need for a wireless implantable ICP-monitoring system as several chronic diseases are associated with ICH. Accurate monitoring of the ICP following a neurosurgical procedure is a basic requirement for adequate treatment [10]-[12]. Since the intracranial contents exist within a rigid vault (the skull), direct ICP measurements require neurosurgical intervention, with its attendant risks. An implant placed during surgery, for the underlying cause of neural disorder, would be a useful adjunct to patient care.
