    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: The invention is directed to techniques for synchronizing the internal clocks of two devices, such as an implantable medical device and an external device, with reduced reliance on periodic polling. In one embodiment, the invention is directed to a technique in which one of the devices computes a time drift. The time drift may occur because the internal clock of one device may run more slowly than the internal clock of the other device. One device may poll the other as a function of the time drift. In another embodiment, a system of medical devices synchronizes internal clocks to a time signal generated by a time reference.
