Patent ID: 7324851

Claim:
A method of managing epilepsy, the method comprising: measuring one or more electrical signals from a patient's brain with one or more intracranial electrodes; receiving the one or more electrical signals in a unit that is implanted intracranially in the patient; extracting parameters from the one or more electrical signals that are indicative of a seizure or predictive of a future seizure, the extracted parameters comprising at least one of a peak-to-valley times, valley-to-peak times, positive phase amplitudes, and negative phase amplitudes; delivering one or more bursts of charge-balanced biphasic stimulus pulses to a patient's brain when the extracted parameters are indicative of undesirable electrical activity in the patient's brain; monitoring the parameters after delivering the one or more bursts of charge-balanced biphasic stimulus pulses; and delivering one or more subsequent bursts of charge-balanced biphasic stimulus pulses to the patient's brain if the monitored parameters indicate that the patient still has undesirable electrical activity in the patient's brain.
