摘要： A circuit arrangement enables an implanted medical device (IMD) to distinguish between a radio frequency (RF) signal and noise that is transmitted by an external programming unit. In an example embodiment, the IMD includes a receiver circuit a counter circuit counts edges of the demodulated signal occurring within a selected time period. A decoder circuit of the receiver circuit decodes the demodulated signal and compares the number of edges counted with a valid signal before the decoded signal is transmitted to a telemetry processor of the IMD. The receiver circuit also includes a validation circuit that verifies the validity of the decoded signal before transmitting the decoded signal to the telemetry processor.

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.
