  • Publication number: 20070260293
    Abstract: A system including an external medical data telemetry device to communicate with an implantable medical device (IMD). The external medical data telemetry device includes a processor, a reconfigurable radio-frequency (RF) transceiver circuit, at least one far-field antenna, and a user interface. The reconfigurable RF transceiver circuit modulates an outgoing IMD data signal and demodulates an incoming IMD data signal using a modulation type that is selectable from a plurality of modulation types by the processor. The processor selects the modulation type using information entered by a user through the user interface.

  • Publication number: 20070185550
    Abstract: A telemetry system for radio-frequency communications between an implantable medical device and an external device providing improved noise immunity is disclosed. Multiple communications channels are used to enable establishment and re-establishment of communications between a particular pair of devices in a multiple device environment.

  • Publication number: 20070135865
    Abstract: A system and method for receiving telemetry data from implantable medical devices such as cardiac pacemakers with improved noise immunity is disclosed. Ambient noise levels and signal strength are monitored and used to adaptively adjust the detection sensitivity of the receiver. Filtering of the received signal is performed to remove both broadband and narrowband noise. Removal of narrowband noise is accomplished with notch filters that are dynamically adjusted in accordance with a detected noise spectrum.

  • Publication number: 20070118188
    Abstract: A method and system for enabling secure communications between an implantable medical device (IMD) and an external device (ED) over a telemetry channel. A telemetry interlock may be implemented which limits any communications between the ED and the IMD over the telemetry channel, where the telemetry interlock is released when the ED transmits an enable command to the IMD via a short-range communications channel requiring physical proximity to the IMD. As either an alternative or addition to the telemetry interlock, a data communications session between the IMD and ED over the telemetry channel may be allowed to occur only after the IMD and ED have been cryptographically authenticated to one other.

  • Publication number: 20060194615
    Abstract: A far-field radio frequency telemetry (RF) system for communicating with an implantable medical device includes a diversity antenna system. An antenna control circuit selects one or more antennas of the diversity antenna system for reducing potential data transmission errors associated with nulls encountered by the telemetry system due to environmental reflections of RF electromagnetic waves. In one embodiment, a different active antenna is selected when a transmission failure deemed to be associated with a null is detected. In another embodiment, a new antenna is selected on a regular basis to reduce the probability of encountering a null. In another embodiment, the telemetry system includes multiple processing paths each associated with one antenna of the diversity antenna system, and a different processing path is selected when the transmission failure deemed to be associated with a null is detected.

  • Publication number: 20060195161
    Abstract: A far-field radio frequency (RF) telemetry system for communicating with an implantable medical device includes a diversity antenna system. Multi-frame messages each including multiple outgoing data frames are transmitted to the implantable medical device. In response, the implantable medical device transmits response data frames each following one or more of the outgoing data frames, according to a predetermined communication protocol. An antenna control circuit selects an antenna of the diversity antenna system for transmitting the outgoing data frames and/or receiving the response data frames based the quality of signal reception associated with the response data frames.

  • Publication number: 20060142821
    Abstract: A system and method for removing narrowband noise from an input signal in which notch filters having notch frequencies corresponding to the noise are dynamically adjusted in accordance with a detected noise spectrum. The method may be applied to telemetry systems for implantable medical devices such as cardiac pacemakers to result in improved noise immunity.

  • Publication number: 20050288738
    Abstract: A telemetry system is presented for enabling radio-frequency (RF) communications between an implantable medical device and an external device in a manner which reduces the power requirements of the implantable device by duty cycling its RF circuitry. A wakeup scheme for the implantable device is provided in which the external device transmits a data segment containing a repeating sequence of special wakeup characters in order to establish a communications session with the implantable device. The wakeup scheme may be designed to operate in the context of a handshaking protocol for collision avoidance.
