Abstract: A navigation system for an airway of a lung includes a wire configured to be inserted into the airway of a patient. The wire may include at least one fiber optic cable with a bragg grating. The system may also include a processing system configured to display a map of at least a portion of the airway. The processing system may be operably coupled to the wire and may be configured to identify a location of the wire on the map.

Abstract: A medical tool includes an access tool and a dissecting obdurator that is placed within a lumen of the access tool. The dissecting obdurator comprises a body having a first edge, a second edge and a cross section, the cross section having a height dimension measured from the first edge to the second edge and a width dimension perpendicular to the height dimension, the height dimension is two or more times the width dimension. The tip of the dissecting obdurator is selectively flexible and coupled to a distal end of the body, the selectively flexible tip being more flexible bending in the axis of the width dimension than bending in the axis of the height dimension.
