Ambulatory medical apparatus and method having telemetry modifiable control software
First Claim
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 the medical device further comprises an MD memory for holding an MD program that controls, at least in part, operation of the medical device. wherein the medical device is capable of executing a first type of software that allows communication with the communication device and also allows medically significant operations to occur, wherein the medical device is capable of executing a second type of software that allows communication with a communication device but does not allow medically significant operations to occur.

Abstract
An implanted medical device (e.g. infusion pump) and handheld communication device wherein the implantable device is capable of operating under control of different software programs, wherein a first program operates after resetting the implantable device and is not capable of providing significant medical functionality but is capable of selected telemetry operations including telemetry operations that allow replacement software to be downloaded, and wherein a second program may be caused to take control of the device and is capable of significant medical functionality and selected telemetry operations but is incapable of receiving replacement software. A software image may be received in multiple messages where each message is provided with its own validation code and wherein a validation code for the whole image is provided and wherein each provided validation code must compared to a derived validation code prior to accepting the validity of the replacement software.
