Abstract

For what is believed to be for the first time, the dynamic study of wireless intracranial pressure measurements in a swine model of traumatic brain injury is described. This achieves an extremely important milestone, since the measurements demonstrate the system's robustness, and the feasibility of acquiring wireless readings of the intracranial pressure resulting from non-impact rotational head injury in swine. The fully implanted device uses a capacitive pressure sensor modulating an RF oscillator, coupled to a planar inverted-F antenna. The results match well those obtained from a standard fibre-optic based (tethered) commercial intracranial pressure monitor, as well as published literature data, and may enable a future trend in the use of implantable wireless systems for research or clinical diagnoses.
