摘要： A telemetry antenna for an implantable medical device includes one or more portions having a non-linear configuration. In some embodiments, the non-linear configuration provides an antenna having a greater antenna length than the linear lengthwise dimension of the antenna structure. In some embodiments, the non-linear configuration is a serpentine pattern.

摘要： An automated identification and configuration system for use with an implantable medical device (IMD) is disclosed. The system includes a first communication circuit that is attached to, or otherwise carried by, a detachable component associated with the IMD such as a medical lead. The communication circuit stores data such as model numbers, serial numbers, technical data, and/or calibration information that describes the additional component. This information may be transferred by the first communications circuit to a second communications circuit that is external to the additional component. This transferred data can be used to automatically configure the internal circuitry and connection functions of the IMD to properly interface with, and support, the additional component. For example, the data can be used to automatically adjust amplifier gains or other sensor circuitry, or to configure a connector block to properly couple to the component. The data may further be entered into a patient record on an external programmer, or may be transferred to a central storage location to be generally accessible to health care providers. In one embodiment, the first communication circuit is a passive RF transponder. This first communication circuit may include a receiver as well as a transmitter to allow the circuit to programmably receive data at the time of component manufacture.

摘要： Implantable medical devices (IMDs) having sense amplifiers for sensing physiologic signals and parameters, RF telemetry capabilities for uplink transmitting patient data and downlink receiving programming and interrogation commands to and from an external programmer or other medical device are disclosed. At least one IC chip and discrete components have a volume and dimensions that are optimally minimized to reduce its volumetric form factor. Miniaturization techniques include forming notch filters of MEMS structures or forming discrete circuit notch filters by one or more of: (1) IC fabricating inductors into one or more IC chips mounted to the RF module substrate; (2) mounting each IC chip into a well of the RF module substrate and using short bonding wires to electrically connect bond pads of the RF module substrate and the IC chip; and (3) surface mounting discrete capacitors over IC chips to reduce space taken up on the RF module substrate. The IC fabricated inductors are preferably fabricated as planar spiral wound conductive traces formed of high conductive metals to reduce trace height and width while maintaining low resistance, thereby reducing parasitic capacitances between adjacent trace side walls and with a ground plane of the IC chip. The spiral winding preferably is square or rectangular, but having truncated turns to eliminate 90° angles that cause point-to-point parasitic capacitances. The planar spiral wound conductive traces are further preferably suspended over the ground plane of the IC chip substrate by micromachining underlying substrate material away to thereby reduce parasitic capacitances.

摘要： A telemetry receiver for an implantable medical device such as a cardiac pacemaker has an RF antenna coupled to a telemetry circuit that includes an out-of-band rejection filter comprising a microelectromechanical filter. The telemetry circuit further includes an amplifier coupled to the microelectromechanical filter and a demodulator coupled to the amplifier. The filter, amplifier and demodulator are all fabricated on a common integrated circuit die. A multichannel telemetry receiver for an implantable medical device has a plurality of microelectromechanical bandpass filters defining individual channels. A multiplexing circuit selects the signal of an individual bandpass filter channel for application to a demodulator circuit that recovers programming data from a modulated RF transmission from a programming unit. Identification of a preferred data transmission channel for communication of programming data to the implanted medical device is determined by obtaining samples of the signals being passed by each of a plurality of microelectromechanical bandpass filters that define individual channels and evaluating the samples to determine the noise level for each channel. The implantable medical device may be programmed to receive downlink telemetry communications from a programming unit on the channel identified as being the preferred data transmission channel having the lowest noise level.

摘要： A microstrip RF telemetry antenna is formed on or within the exterior surface of an implantable medical device housing that is formed either of a conductive metal or of a non-conductive dielectric material. The microstrip antenna is formed of an electrically conductive radiator patch layer that is laminated upon an exterior facing side of a dielectric substrate layer of relatively constant thickness. A conductive ground plane layer is formed on the opposite side of the dielectric substrate layer to extend parallel to and at least coextensively with the radiator patch layer. The radiator patch layer is coupled to the transceiver circuitry within the implantable medical device housing by a feedthrough extending through the dielectric substrate layer, the ground plane layer and the implantable medical device housing side wall. If the implantable medical device housing is conductive it may form the ground plane layer over which the dielectric substrate layer and the radiator patch layer are formed through deposition or other techniques. If the implantable medical device housing is formed of a suitable non-conductive dielectric material, the ground plane layer is formed on an interior surface thereof and the radiator patch layer is formed on an exterior housing surface thereof, preferably by deposition techniques. The ground plane layer may be recessed to form a cavity backed ground plane that receives the dielectric layer and radiator patch layer within the cavity. The exterior surfaces of the radiator patch layer, the dielectric layer and any exposed surface of the ground plane layer may be electrically insulated by a radome layer.

摘要： A system and method for communicating with a medical device implanted in an ambulatory patient and for locating the patient in order to selectively monitor device function, alter device operating parameters and modes and provide emergency assistance to and communications with a patient. The implanted device includes a telemetry transceiver for communicating data and operating instructions between the implanted device and an external patient communications control device that is either worn by or located in proximity to the patient within the implanted device transceiving range. The control device preferably includes a communication link with a remote medical support network, a global positioning satellite receiver for receiving positioning data identifying the global position of the control device, and a patient activated link for permitting patient initiated personal communication with the medical support network. A system controller in the control device controls data and voice communications for selectively transmitting patient initiated personal communications and global positioning data to the medical support network, for initiating telemetry out of data and operating commands from the implanted device and transmission of the same to the medical support network, and for receiving and initiating re-programming of the implanted device operating modes and parameters in response to instructions received from the medical support network. The communications link between the medical support network and the patient communications control device may comprise a world wide satellite network, hard-wired telephone network, a cellular telephone network or other personal communications system.
