Abstract:
An automatic drug therapy delivery system, capable of being implanted into a patient comprised of:a) at least one implantable reservoir of a drug to be administered to the patient; b) an implantable, programmable pump coupled to the implantable reservoir, for delivering from the implantable reservoir at least one drug from the reservoir to the patient; c) a programmable first memory module for storing a dose infusion characteristic; d) a first input port receiving a first input signal from a patient so as to cause the pump to administer a bolus of drug, the bolus limited by the dose infusion characteristic; e) a programmable microprocessor coupled to the programmable first memory module and to the first input port, the programmable microprocessor monitoring the amount of drug therapy administered to the patient according to instructions stored in the programmable first memory module and ensuring against overdosage or underdosage of the drug therapy; and f) a programming link coupled to the implanted programmable pump for receiving instructions for the implantable programmable pump from outside the patient's body and for programming the dose infusion characteristic, wherein the microprocessor performs the step selected from the group consisting of denying further activation requests, activating the smallest programmed dose when an activation request is made and prompting the patient to select the next lowest base rate, when an overdosage condition is detected.
