Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. A system for tracking a medical instrument, the system comprising:
a medical device configured to be inserted into a body, the medical device comprising:
a plurality of coordinated electromagnetic sensors configured to generate a virtual axis of travel for the medical instrument along a channel of the medical device through an opening of the medical device, the virtual axis of travel aligned with a tool insertion axis, wherein structure of each of the plurality of coordinated electromagnetic sensors and position of each of the plurality of coordinated electromagnetic sensors on the medical device are coordinated to generate a vector-sum of individual sensitivities of the plurality of the coordinated electromagnetic sensors that aligns with the tool insertion axis,
wherein the plurality of coordinated electromagnetic sensors comprises a first coil and a second coil, the first coil in concentric arrangement with a longitudinally-extending central axis of the medical device and the second coil in orthogonal arrangement to the first coil, the first coil and the second coil electrically connected in series; and

a tracking circuitry configured to track the plurality of coordinated electromagnetic sensors to determine a virtual axis position of the medical instrument along the generated virtual axis of travel in a tracking space.
