The present invention is directed to techniques and apparatus for infusing drugs into the brain to treat movement disorders resulting in abnormal motor behavior. The invention employs an implantable pump and a catheter, the catheter having a proximal end coupled to the pump and a discharge portion for placement adjacent a predetermined infusion site in the brain for infusing therapeutic dosages of the one or more drugs into the brain. The pump is operated to discharge a predetermined dosage of the one or more drugs through the discharge portion of the catheter into the infusion site. A sensor may be used in combination with the implantable pump and catheter, whereby the sensor generates a signal relating to the extent of the abnormal motor behavior. The therapeutic dosage is regulated so that the dosage is adjusted in response to an increase in the abnormal behavior to decrease the abnormal motor behavior.
A method of using one or more drugs to treat a movement disorder resulting in abnormal motor behavior 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 comprising the steps of:
