Microprocessor controlled ambulatory medical apparatus with hand held communication device
First Claim
1. A communication system for a medical device, the system comprising:
- 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) a 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, and 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 MD memory; and
a communication device (CD) comprising;
at least one CD telemetry system configured to send messages to or receive messages from the MD telemetry system;
at least one CD memory; 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 MD is configured to selectively disable a MD component or activity of a MD component for transmission or reception of messages by the MD telemetry system, further wherein the MD is configured to selectively enable and disable the MD telemetry system; and
wherein the MD is configured to disable the MD component or activity of the MD component when the MD telemetry system is enabled.

Abstract
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.
