Method for the detection and treatment of aberrant neural-electric activity
First Claim
1. A method for detecting and treating aberrant neural-electric activity (ANEA) in a brain of a patient causing an epileptic pre-seizure event or a seizure event, the method comprising:
- positioning, at least partially in the brain or skull, three electrode members, wherein each electrode member defines a different orthogonal axis of a Cartesian coordinate system;
detecting, from inside the brain or skull, an electric field caused by ANEA in the brain wherein the electric field is detected using the Cartesian coordinate system defined by the three electrode members;
determining an electric field vector characteristic from the detected electric field;
interpreting the electric field vector characteristic as being a marker to the epileptic pre-seizure event or seizure event; and
delivering a dose of anti-seizure medication to the patient'"'"'s brain in response to the interpreted marker to the epileptic pre-seizure event or seizure event.

Abstract
An apparatus for detection of ANEA comprising an introducer having at least one lumen. The introducer is introduced into brain tissue through an opening in the skull. A reference electrode is positioned at an introducer distal portion. A plurality of electrode members are advanceable within the at least one lumen with each member having an insulated portion and an exposed distal portion. The members have a non-deployed state in the introducer and a deployed state when outwardly advanced out of the introducer. In the deployed state, the members are substantially orthogonal to each other with the exposed distal portions defining a detection volume capable of determining an electric field vector produced by the ANEA and the direction of foci of the ANEA.
