    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： An implantable, self-contained, user-attachable or detachable telemetry module plugs into an implantable medical device to provide or supplement one or more telemetry functions needed by a patient having certain health conditions. A user-attachable or detachable telemetry module allows a user, such as a physician or other care provider, to select a telemetry module and attach it to a medical device. Various types of telemetry are implemented as various user-attachable or detachable telemetry modules, each providing one or more telemetry functions suitable for a particular patient whose condition imposes a particular demand on telemetry. A care provider selects a user-attachable or detachable telemetry module most suited for the particular patient, which improves healthcare cost efficiency. One example of user-attachable or detachable telemetry module includes a radio-frequency (RF) transmitter-receiver circuit module and a lead carrying an antenna. In one example, the circuit module is away from the implantable medical device and coupled to the implantable medical device through the lead. In another example, the circuit module directly attaches to the implantable medical device.

    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 apparatus and method for enabling an implanted fractal antenna for radio frequency communications between an implantable medical device and an external device. The fractal antenna may be disposed within or outside of a header assembly of the device housing. Various examples include a three dimensional patterned cylinder usable as a tissue anchor or stent. In another embodiment the antenna may be cast, molded, stamped, punched, milled, laser cut, etched or other methods to form a fractal pattern in conductive media. In another embodiment the antenna may be formed of a printed circuit board (PCB) either with or without an included ground reference plane. In another embodiment the antenna may be formed in a fractal pattern and then wrapped around a part of the implantable device.
