An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. The pump exchanges messages with an external device via telemetry. Each processor controls a different part of the drug infusion mechanism such that both processors must agree on the appropriateness of drug delivery for infusion to occur. Delivery accumulators are incremented and decremented with delivery requests and with deliveries made. When accumulated amounts reach or exceed, quantized deliverable amounts, infusion is made to occur. The accumulators are capable of being incremented by two or more independent types of delivery requests. Operational modes of the infusion device are changed automatically in view of various system errors that are trapped, various system alarm conditions that are detected, and when excess periods of time lapse between pump and external device interactions.

1. A medical system, comprising:a) an ambulatory medical device (MD) comprising 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 medical device, wherein the medical device is configured to provide a treatment to a body of a patient or to monitor a selected state of the body; 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 communication device, wherein the CD telemetry system sends messages to or receives messages from the MD telemetry system, wherein at least one of the medical device and the communication device comprises a plurality of electronic modules, wherein at least one of the modules is at least a portion of the time switched from an active state to a power saving state when not in use and switched again to an active state when needed, and wherein the at least one MD processor applies power and clocking signals to the plurality of electronic modules on an as needed basis. 2. The system of claim 1 wherein at least one module is switched from an active state to an inactive state by operation of software.3. The system of claim 1 wherein at least one module is switched from a power saving state to an active state by operation of software.4. The system of claim 1 wherein at least one module is switched from an active state to an inactive state by operation of hardware.5. The system of claim 1 wherein at least one module is switched from a power saving state to an active state by operation of hardware.6. The system of claim 1 wherein at least one of the plurality of electronic modules is switched from an active state to a power saving state by withdrawing power from the module.7. The system of claim 1 wherein at least one of the plurality of electronic modules is switched from an active state to a power saving state by withdrawing a clock signal from the module.8. The system of claim 1 wherein the plurality of electronic modules comprise one or more of (1) a CPU, (2) ROM, (3) a RAM module, (4) a synchronous serial interface, (5) an audio alarm driver, (6) a pump driver, (7) a SEEPROM, (8) an analog-to-digital converter, (9) a telemetry system, (8) a bit map LCD, (9) a sensor driving circuit, (10) a voltage divider circuit, (11) a vibration alarm driver, or (12) a timer module.9. The system of claim 8 wherein at least four of the electronic modules are included in the system and at least four of the modules are switched.10. The system of claim 9 wherein at least eight of the electronic modules are included in the system and at least eight of the modules are switched.11. The system of claim 1 wherein the plurality of modules are located within a single application specific integrated circuit.12. The system of claim 1 wherein at least one MD processor comprises a CPU module and a plurality of other electronic modules.13. The system of claim 1 wherein at least one CD processor comprises a CPU module and a plurality of other electronic modules.14. The system of claim 1 wherein at least one MD processor comprises a single application specific integrated circuit.15. The system of claim 1 wherein at least one CD processor comprises a single application specific integrated circuit.16. The system of claim 1 wherein the medical device comprises at least one of (1) an implantable infusion pump for selectively dispensing a selected drug, (2) an implantable infusion pump for selectively dispensing insulin, (3) an implantable sensor for sensing a selected state of the body, (4) an implantable sensor for sensing glucose level, or (5) an implantable electrode for selectively stimulating a portion of the body of the patient.17. The system of claim 1, wherein operation protocols decrease the amount of time the plurality of electronic modules are in operation.18. The system of claim 19, wherein the MD includes program code that communicates with the CD prior to using an internal alarm process.19. The system of claim 1, wherein the MD includes program code that activates the at least one MD telemetry system for a short period of time on a periodic basis to listen for incoming messages.20. The system of claim 19, wherein the short period of time is about four milliseconds.21. The system of claim 19, wherein the periodic basis is about every two seconds.22. The system of claim 19, wherein the MD includes program code that deactivates the at least one MD telemetry system when no messages are incoming.
