The implantable medical device may include a housing that hermetically encloses electronic components of the implantable medical device and a fixation mechanism that affixes the implantable medical device to a target location, such as a wall of a vessel. The fixation mechanism functions as a radiating element of an antenna of the implantable medical device. The housing of the implantable medical device may include a conductive loop that electrically couples to a telemetry module and magnetically couples to the fixation mechanism. The telemetry module may provide signals to be transmitted to the inner loop and those signals are magnetically coupled between the inner loop and the fixation mechanism, which radiates the signals.

摘要： An implantable medical device (IMD) and methods of fabricating the same are provided. An IMD can include a housing and a cofire ceramic module (CCM) coupled to the housing. The CCM can include an antenna cofire-integrated in the CCM. The antenna can include a plate composed of conductive material, and conductive antenna elements that are annular substrates having perimeters substantially coextensive with the perimeter of the plate. The antenna can also include interconnections. A first set of interconnections can be coupled between the plate and one of the conductive antenna elements, and a second set of interconnections can be coupled between the conductive antenna elements. The antenna can also include a feed line conductively coupled to the plate. In some embodiments, the feed line can be substantially serpentine-shaped to adjust impedance in the CCM.

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： The disclosure describes examples of antennas used for communication with an implantable medical device (IMD). As one example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing, and a planar antenna, having a curved structure, that is stacked on an external side of the housing and coupled to the communication circuitry. As another example, the IMD includes a housing configured to house communication circuitry within an internal side of the housing and an antenna having a curved structure formed on an external side of the housing and coupled to the communication circuitry. A resonant frequency of the antenna is based on a dielectric constant of tissue surrounding the antenna when the IMD is implanted, and a current distribution of the antenna is in-phase in opposite sides of the antenna.

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.
