Patent ID: RE42934

Claim:
A patient monitoring system comprising: a transceiver unit to be located in immediate proximity to a patient's body for communicating with a device implanted in the patient's body and with a telephone system outside the patient's body, the transceiver unit comprising, a GPS location system for receiving satellite transmitted information from a set of earth orbiting satellites, an IMD receiving telemetry circuit means for receiving telemetry from said implanted device, a memory circuit for storing data relating to data received from said implanted device and from said earth orbital satellite, telecommunications module for communication through wireless telephonic channels to said telephone system, real time clock circuit producing an output signal for a real time clock, transmission initiation processor for generating an automatic transmission over said telecommunications module through said wireless telephonic channels containing information related through said implantable device to said transceiver unit, said automatic transmission to occur at a set of periodically occurring fixed times, and real time clock circuit update processor for interpreting received satellite transmitted information and providing an update for the real time clock circuit based on said satellite transmitted information so that said transmission initiation processor can operate within an extremely accurately clocked time slice.
