Embedded microwave system for monitoring of intracranial pressure

Intracranial pressure is of increasing interest in the management of patients who are suffering from various neurological disorders such as hydrocephalus, traumatic brain injury, and blast injury. Long-term monitoring of intracranial pressure may be desirable in these conditions to aid in determining the outcome of any treatment. A completely implantable microwave device for monitoring of intracranial pressure has been designed and characterized. The application of an embedded Planar Inverted-F antenna in this implant is also investigated.
