摘要： This disclosure describes antenna structures for use in an implantable medical device. The antenna structure may include an inner portion that is magnetically coupled to an outer portion. In one example, the inner and outer portions comprise conductive loops. In accordance with the techniques of this disclosure, a capacitive sensor is electrically coupled to one of the conductive loops of the antenna of the implantable medical device. As the capacitance of the capacitive sensor changes as a function of the sensed parameter, an impedance of the antenna varies with the output of the capacitive sensor. This variation in impedance of the antenna modulates a carrier signal with the measured parameter. In other words, the measured parameter is modulated onto the carrier signal as a change in amplitude caused by variation in impedance of antenna during radiation/transmission.

摘要： Medical devices are provided with multi-element antenna systems that may function to automatically tune the antenna as a function of the operating environment of the medical device. The tuning methodology may incorporate a multi-element antenna having a variable capacitive element on a first of the antenna elements with that antenna element being driven by a second of the antenna elements. In an embodiment, a multi-element antenna system may acquire measurements of predefined criteria and the antenna may be tuned as a function of the measured criteria to optimize operation of the antenna in both reception and transmission of signals. In so doing the antenna impedance can be matched to the transmission line impedance.

摘要： This disclosure is directed to a three-dimensional antenna that may be used for an implantable medical device (IMD). The antenna includes a first antenna portion that includes a plurality of segments arranged substantially parallel to one another in a first plane. The antenna further includes a second antenna portion that includes a plurality of segments arranged substantially parallel to one another in a second plane that is substantially parallel to the first plane. The antenna further includes a third antenna portion that includes a plurality of segments arranged substantially parallel to one another in a third plane. The plurality of segments of the third portion are coupled between segments of the first and second portions. The third plane is arranged substantially perpendicular to the first plane and the second plane.
