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.

The system of claim 3 wherein said transducers and said microphone are respectively oriented to avoid coupling sound energy from said transducers to said microphone. 5. The system of claim 3 including insulation material associated with said transducers for directing produced sound energy into said middle ear cavity and away from said microphone. 6. The system of claim 3 wherein said circuit means is hermetically sealed. 7. A system for aiding a patient to hear, said system comprising: a pair of spaced speakers; said speakers being implanted adjacent to said patient's middle ear cavity for directing phase offset sound energy into said cavity in response to phase offset electric drive signals individually applied to each of said speakers; a microphone responsive to sound energy incident thereon for producing electric output signals; and circuit means responsive to said electric output signals for producing said phase offset electric drive signals for individually driving each of said speakers. 8. The system of claim 7 wherein said speakers and said microphone are respectively positioned to prevent sound energy produced by said speakers from being coupled to said microphone. 9. The system of claim 8 wherein said microphone is mounted adjacent to said patient's outer ear. 10. The system of claim 8 wherein said speakers are mounted adjacent to the middle ear cavity of said patient's first ear and said microphone is mounted adjacent to said patient's second ear. 11. The system of claim 7 including insulation material for directing sound energy produced by said speakers into said middle ear cavity and away from said microphone. 12. The system of claim 7 wherein at least one of said speakers is oriented for directing sound energy to vibrate said patient's middle ear ossicles. 13. The system of claim 7 wherein said circuit means includes wires connecting said microphone to said speakers. 14. The system of claim 7 wherein said circuit means includes RF transmitter/receiver circuitry for wirelessly coupling said microphone to said speakers. 15. The system of claim 7 wherein said circuit means includes microphone circuitry and speaker circuitry; said microphone circuitry including analog-to-digital converter means for converting said microphone electric output signals and an RF transmitter for transmitting said converted output signals; and said speaker circuitry including an RF receiver for receiving said converted microphone output signals and first and second digital-to-analog converter means for converting said received signals to produce said phase offset drive signals for individually driving each of said speakers. 16. The system of claim 15 further including programmable sound processing circuitry in said microphone circuitry and/or said speaker circuitry for mitigating the particular hearing impairment of said patient. 17. The system of claim 7 including a rechargeable battery for powering said circuit means. 18. The system of claim 7 wherein said circuit means is hermetically sealed. 19. A method of enhancing a patient's hearing comprising: mounting a pair of spaced transducers adjacent to said patient's middle ear cavity; and supplying phase offset electric drive signals to each of said transducers for introducing sound energy into said middle ear cavity. 20. The method of claim 19 wherein at least one of said transducers is oriented to direct sound energy to vibrate said patient's middle ear ossicles. 21. The method of claim 19 further including providing a microphone for producing electric output signals representative of sound incident on said microphone; and further including the step of processing said microphone output signals to produce said phase offset electric drive signals.
