    摘要: An implantable medical device communication system communicates information between an implantable medical device and at least one slave device by way of a two-wire bus. Slave devices may include remote sensors and other implantable medical devices. The implantable medical device includes a communication unit to combine data and power for transmission over the two-wire bus. The transmitted signal is selectively changeable between a first and second voltage. The slave device includes a recovery unit to recover data and power from the received signal. An extendable command set includes long commands to set up the system and shorter commands to conserve power. Selectively addressable multicast commands, and shortened quick trigger commands conserve power by lowering system current and increasing data throughput.

    摘要: Method and apparatus for detecting pressure waves caused by movement of a body organ, transmitted through a catheter (18) to an implanted medical device employing a pressure wave transducer (32) mounted in relation to the proximal end (40) of the catheter (18). The system may also include a reference transducer (34) having the same pressure wave response characteristics as the pressure wave transducer (32) but isolated from the proximal connector end (40) for providing a reference signal including common mode pressure wave noise that both transducers (32, 34) are simultaneously subjected to. The pressure wave signal and the reference signal are preferably amplified, bandpass filtered, stored, telemetered out or used to trigger a device operation. The pressure and reference wave transducers (32, 34) preferably are piezoelectric crystal transduces or accelerometers in direct or indirect mechanical contact with the proximal connector end (40) of the catheter and is encapsulated from the body within a device connector assembly (20). Cardiac pressure waves and respiration pressure waves are both transmitted proximally through the lead body (18) to the pressure wave transducer (32). Pressure wave signals may be derived in parallel to detect particular characteristic of the cardiac and/or respiratory cycle to provide timing signal(s) for controlling the device operations.

    摘要: An implantable medical device communication system communicates information between an implantable medical device and at least one slave device by way of a two-wire bus. Slave devices may include remote sensors, actuators and other implantable medical devices. The implantable medical device includes a communication unit to output commands and power pulses, and receive information from the slave devices over the two-wire bus. The implantable medical device and slaves communicate over the bus by selectively changing one of the lines of the bus between a first and second voltage, the second voltage substantially equal to a reference voltage of the second line, e.g., zero volts. In some embodiments, the power pulses take the form of bipolar pulse pairs. The slave device includes a recovery unit to recover power from the power pulses.
