A probe or catheter, usable with a navigation system, includes a longitudinal lumen that curves outwardly through a sidewall prior to reaching a distal tip of the probe. The distal tip contains a position sensor as part of the navigation system. The lumen provides a working channel that guides a tool into a sidewall of a branched structure without requiring the distal end of the probe to be facing the branched structure.
