ABSTRACT:
Apparatus for performing a medical procedure on a tissue within a body of a subject includes a wireless tag which is fixed to the tissue and includes a first sensor coil. A second sensor coil is fixed to a medical device for use in performing the procedure. An integral processing and display unit includes a plurality of radiator coils, along with processing circuitry and a display. The radiator coils generate electromagnetic fields in a vicinity of the tissue, thereby causing currents to flow in the sensor coils. The processing circuitry processes the currents so as to determine coordinates of the tag relative to the medical device. The display is driven by the processing circuitry so as to present a visual indication to an operator of the medical device of an orientation of the device relative to the tag.
