Medical Device Telemetry Receiver Having Improved Noise Discrimination

US Patent:
6201993, Mar 13, 2001
Filed:
Dec 9, 1998
Appl. No.:
9/208883
Inventors:
John M. Kruse - New Brighton MN
David R. Jurek - Columbia Heights MN
Assignee:
Medtronic, Inc. - Minneapolis MN
International Classification:
A61N 136
US Classification:
607 30
Abstract:
A method and apparatus for detecting an RF signal transmitted between an implantable medical device (IMD) and an external medical device programmer in a telemetry session and discriminating the telemetry transmitted RF signal from transient and steady state noise corrupting it. The external programmer includes a programmer telemetry antenna tuned circuit adapted to be driven into oscillation to generate tuned circuit output signals in response to telemetry uplink transmissions of telemetry uplink signals from the IMD, wherein the tuned circuit output signals can exhibit noise artifacts due to contamination by electrical noise. An RF telemetry receiver section detects and demodulates the telemetry uplink signals from the tuned circuit output signals and provides a demodulated uplink signal having a demodulated uplink signal amplitude that varies with time as a function of telemetry uplink signal amplitudes and noise artifacts. The receiver section includes an adaptive comparator circuit for comparing the demodulated uplink signal amplitude with an adaptive threshold signal and providing a receiver output signal when the demodulated uplink signal amplitude exceeds the adaptive threshold amplitude of the adaptive threshold signal.
