Cross-band communications in an implantable device
First Claim
1. An implantable medical device, comprising:
- a) a battery;
b) at least one sensor that is powered by the battery and configured to monitor a physiological condition of the body of a patient;
c) sensor electronics configured to process a signal received from the at least one sensor;
d) a wireless receiver that is configured to continuously draw less than 10 micro-amps of current from the battery when implanted, wherein the receiver is configured to receive a first wireless communication from an external device in a first frequency band of a range of frequencies less than 1 MHz; and
e) a wireless transmitter that is separate from the receiver,f) wherein after receipt by the receiver of a first wireless communication from the external device at the first frequency band, the wireless transmitter is configured to draw power from the battery and send at least one second wireless communication related to at least one physiological signal sensed by the at least one sensor to the external device using a second frequency in a range of frequencies above 10 MHz.

Abstract
An ambulatory monitoring device includes a sensor to monitor a physiological signal and a battery power source. The device also includes a wireless receiver 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 device further includes a wireless transmitter 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.
