A system and method for navigating to a target site in a patient is provided. The system includes an extended working channel (116) and a tool (100) usable with an electromagnetic navigation system (130). In particular, the extended working channel (116) and the tool (100) contain an electromagnetic sensor (120) configured to provide location information within a patient of the extended working channel (116) and the tool (100) to the electromagnetic navigation system (130). The distance from the tool (100) and the target site can then be determined and displayed to a clinician on a display device.
