Abstract:
1. A method of delivering a drug dosage from a drug dispenser to receptors of the central nervous system of a patient's body to provide a prophylactic cardiac therapy, the method comprising the steps of: surgically implanting a drug infusion catheter with a distal drug delivery portion disposed at a predetermined central nervous system site; coupling a proximal end of the drug infusion catheter to a drug delivery pump; one of manually triggering and automatically operating the drug delivery pump to discharge a predetermined dosage of a sympatholytic cardiovascular agent to a central nervous system site to provide a prophylactic cardiac therapy to the patient; surgically implanting a physiologic sensor in the patient's body; operating the physiologic sensor to derive a physiologic parameter associated with one of: a myocardial ischemia condition, a cardiac arrthytmia condition, an episode of angina, a hypertension condition, and a relatively elevated sympathetic drive condition; and adjusting the dosage as a function of the monitored physiologic parameter.
