1. A magnetic signature imprinting system, comprising:
an imprinting apparatus configured to operatively engage a medical device, the imprinting apparatus comprising:
a frame;
a device engagement mechanism coupled with the frame, the device engagement mechanism configured to receive and position the medical device within an imprinting space of the frame, the medical device including one of a needle, a stylet, a guidewire, an obturator, a probe, a tunneller, a stent, a port, a balloon device, or a sheath; and
a number of electromagnets disposed within the imprinting space; and
a console coupled with the number of electromagnets, the console having a number of processors and a non-transitory computer-readable medium having logic stored thereon that, when executed by the number of processors, performs operations that include selectively activating one or more of the number of electromagnets to imprint a defined magnetic signature on the medical device to define an imprinted magnetic signature that includes a series of dipoles disposed along the medical device.
