Abstract
A medical system tracks the position of a medical instrument within a body of a patient. The medical instrument includes an elongated flexible printed circuit and an electromagnet structure having a conductive coil wound around a core. A control circuit applies an excitation signal across the conductive coil. Electrical current running through the conductive coil (wound around the core) generates a magnetic field. A plurality of sensors sense parameters of the magnetic field and output sensor signals. The control circuit calculates the position of the medical instrument based on the sensor signals.
