    摘要: A telemetry system provides a selectable encoding protocol, including, for example, a plurality of redundancy levels, where the encoding protocol is selected based on a measure of transmission efficiency. For example, later messages are transmitted using an increased redundancy if a prior message exhibits a low signal to noise ratio. A communication session is initiated using a first level of redundancy and the level is adjusted based on a channel characteristic or a measured parameter.

    摘要: An implantable medical device system includes an implanted device communicating with an external device via telemetry. The implanted device and the external device each have a telemetry module connected to an antenna system to support a radio-frequency (RF) telemetry link. The antenna system of the external device has a manually or automatically controllable directionality. The controllable directionality is achieved, for example, by using two or more directional antennas, one non-directional antenna and one or more directional antennas, or an electronically steerable phased-array directional antenna.

    摘要: 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.

    摘要: Systems, methods and devices facilitating wireless communication with a medical device employ an antenna that provides for increased efficiency, broader bandwidth, and/or improved impedance matching characteristics. In some cases, this antenna is an inverted-f antenna, and in one particular case, the antenna is a non-planar inverted-f antenna. In some cases, the antenna is disposed within a dielectric housing extending along a portion of the side of the medical device.
