Microprocessor controlled ambulatory medical apparatus with hand held communication device

A medical system, comprising:

• a) an ambulatory medical device (MD) configured to provide a treatment to a body of a patient having a housing, the MD further including within the housing:
• (1) a reservoir capable of containing a drug, (2) a pumping mechanism for transferring the drug from the reservoir to the body of a patient, (3) MD electronic control circuitry that further comprises at least one MD telemetry system and at least one MD processor that controls, at least in part, operation of the MD telemetry system and operation of the MD, including, at least in part, operation of the pumping mechanism, wherein a first portion of the MD telemetry system is incorporated into the MD processor and a second portion of the MD telemetry system is external to the MD processor, and (4) a memory for storing a delivery profile containing a plurality of preprogrammed basal rates, each preprogrammed basal rate corresponding to a predefined time period during which the drug is continuously delivered at the preprogrammed basal rate to the body of the patient;
• and
• b) a communication device (CD) comprising CD electronic control circuitry that further comprises at least one CD telemetry system and at least one CD processor that controls, at least in part, operation of the CD telemetry system and operation of the CD, wherein the CD telemetry system sends messages to or receives messages from the MD telemetry system,
• wherein the communication device is capable of being programmed with at least two quantities relating to at least two amounts of drug delivery,
• wherein a first quantity of the at least two quantities is the preprogrammed basal rate derived from the delivery profile with the corresponding predefined time period that corresponds to a current time,
• wherein a second quantity of the at least two quantities is a temporary basal rate at which the drug is continuously delivered, the temporary basal rate being programmed on the communication device and sent to the medical device without changing the delivery profile stored on the medical device,
• wherein a third quantity of the at least two quantities is a temporary basal rate duration during which the drug is delivered at the temporary basal rate instead of the preprogrammed basal rate,
• wherein a fourth quantity of the at least two quantities is a bolus amount of the drug to be delivered, and
• wherein the medical device is configured to deliver a net amount of the drug to the body of the patient that is equal to a sum of the preprogrammed basal rate and the bolus amount if no temporary basal rate is programmed for the current time, and to deliver a net amount of the drug that is equal to a sum of the temporary basal rate and the bolus amount if a temporary basal rate is programmed for the current time.
