<p>This invention concerns systems and methods for locating an operative element (12) within an interior body space use a locating probe (14), which includes at least one transmitting element to transmit an electric waveform output within at least a portion of the space. The systems and methods also use a sensing element (16), which is adapted to be carried by the operative element to sense a local electric waveform within the space. A processing element coupled to the sensing element generates a processed output that locates the sensing element relative to the locating probe based, at least in part, upon a differential comparison of the waveform output and the sensed local waveform.</p> |
