Techniques for treating epilepsy by brain stimulation and drug infusion
First Claim
1. A method of using at least one drug and electrical stimulation to treat a neurological disorder producing a condition resulting from an onset of a seizure in a body by means of an implantable pump and a catheter having a proximal end coupled to said pump and a discharge portion for infusing therapeutic dosages of said at least one drug and by means of an implantable signal generator and at least one electrode, said method comprising the steps of:
- surgically implanting said catheter in a brain so that the discharge portion lies adjacent a predetermined infusion site in the brain;
implanting said signal generator in said body;
implanting said at least one electrode adjacent said predetermined infusion site;
coupling said at least one electrode to said signal generator;
generating stimulation pulses with said signal generator; and
operating said pump to discharge a predetermined dosage of said at least one drug through said discharge portion of said catheter into said infusion site, whereby said neurological disorder is treated by drug infusion and said stimulation pulses.

Abstract
Techniques using one or more drugs and electrical stimulation for treating a neurological disorder, including epilepsy, by means of an implantable signal generator and electrode and an implantable pump and catheter. A sensor is used to detect a seizure or symptoms resulting from the onset of a seizure. A microprocessor algorithm analyzes the output from the sensor in order to regulate the stimulation and drug dosage delivered to the neural tissue.
