Claim:
1. A medical device identifier, comprising: a coil; a computer subsystem comprising a processor and memory, the memory holding instructions executable by the processor and also holding a plurality of digitized waveforms; a digital-to-analog converter coupled to the processor; drive circuitry coupled to the coil and the digital-to-analog converter; and receiver circuitry coupled to the coil and the computer subsystem; wherein the instructions, when executed by the processor, cause the medical device identifier to: sequentially excite the coil, via the digital-to-analog converter and the drive circuitry, to generate electromagnetic waveforms corresponding to one or more of the digitized waveforms; receive and digitize, via the coil and the receiver circuitry, a returned electromagnetic waveform transmitted from a medical device in response to the electromagnetic waveforms generated by the medical device identifier; and identify the medical device based on the digitized returned electromagnetic waveform, wherein the memory further holds a plurality of digital templates corresponding to different medical devices, and wherein the instructions, when executed by the processor, cause the medical device identifier to identify the medical device based on a comparison of the digitized returned electromagnetic waveform with the plurality of digital templates.
