DEVICE, SYSTEM, AND METHOD FOR DUAL PURPOSE TRACKING

Abstract: a device includes a main body having a major portion formed from a ferromagnetic material configured for a dual purpose. the ferromagnetic material serves both a primary functioning purpose (structural, sensing, tracking, or therapeutic) and a secondary electromagnetic tracking purpose. the ferromagnetic material permits determining location and orientation of the device by a sensing system without requiring dedicated tracking sensors or manufacturing changes. the wireless unpowered ferromagnetic material generates trackable electromagnetic signatures when exposed to the magnetic fields, enabling precise location and orientation tracking while maintaining original device functionality without additional specialized sensors. this permits for the leveraging of existing ferromagnetic components like catheter braids, stent structures, or device frames that are already integrated into medical devices for their primary purposes.
