Cross-band communications in an implantable device
First Claim
1. An implantable medical device to be implanted into a body of a patient, the implantable medical device comprising:
- a) one or more sensors configured to monitor physiological condition of the body of the patient;
b) sensor electronics configured to process a signal received from the one or more sensors;
c) a transceiver, wherein the transceiver is configured to;
i) receive incoming information from an external device in a first frequency band ranging from about 125 to about 134 kHz, andii) send outgoing information to the external device in a second frequency band in a range selected from 402 MHZ to 405 MHz and from about 902 to about 928 MHz; and
d) a power supply for powering the implantable medical device including the transceiver.

Abstract
An ambulatory monitoring device includes a sensor to monitor a physiological signal and a battery power source. The device also includes a wireless transceiver adapted to monitor a first frequency band having frequencies below 1 MHz and configured to detect and receive, using less than 10 micro-amps of current from the battery power source when operating, wireless communications within the first frequency band from a remote device at least one meter away. The wireless transceiver is further adapted to transmit—after receipt from the remote device of a first wireless communication within the first frequency band that includes an invitation for further communication—a second wireless communication in a second frequency band having frequencies above 10 MHz, the second wireless communication comprising data indicative of the physiological signal as sensed by the sensor.
