Abstract

Disclosed is an adapter assembly for accurately positioning a removable biosensor implanted in the cranium or skull cap. The assembly comprises an outer sleeve member insertable into a hole bored through the skull cap and an inner sleeve member coaxial with the outer sleeve. The sleeve members are constructed so as to permit slidable insertion and removal of the biosensor and to ensure accurate, tilt-free alignment thereof, thus enabling precise, error-free measurement.
