Abstract:
A method of using one or more drugs to therapeutically treat a neural disorder including a movement disorder over a predetermined time period 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 one or more drugs, as well as a signal generator and at least one implantable electrode having a proximal end and a stimulation portion, said method comprising the steps of:surgically implanting said electrode so that the stimulation portion lies adjacent a predetermined stimulation site in subdural neural tissue;surgically implanting said catheter so that the discharge portion lies adjacent a predetermined infusion site in subdural neural tissue;coupling said proximal end of said electrode to said signal generator;operating said signal generator to treat said neural disorder by stimulating said stimulation site during at least a portion of said predetermined time period;operating said pump to treat said neural disorder by discharging a predetermined dosage of said one or more drugs through said discharge portion of said catheter into said infusion site during at least a portion of said predetermined time period, whereby said neural disorder is treated.
