Abstract
A telemetry system includes a remote monitoring station, a repeater worn externally by a patient and a quasi-passive transponder attached to a device implanted in the patient. The remote monitoring station communicates to the repeater to initiate an interrogation routine between the repeater and the transponder to extract patient condition information from the implanted device. When the repeater receives the condition information, it relays it to the remote monitoring station. The transponder is specially designed to operate with an extremely low level of power, less than 1 nW/baud, and to be compatible for attachment to existing implanted devices. The transponder can operate at a very high data rate, including a rate of about 100 kbps.
