A surgical system comprising: a bronchoscope having a working channel; an extended working channel sized for insertion into the working channel of the bronchoscope and to receive one or more instruments therethrough; a magnetic field generator; a locatable guide for insertion into the extended working channel, the guide including an electromagnetic sensor for sensing the magnetic field generated by the magnetic field generator and lockable into position such that the sensor extends a desired distance beyond the distal tip of the extended working channel; a handle, connected to and forming a proximal end of the extended working channel, that can be manipulated to steer the extended working channel and the locatable guide; a tracking system for tracking the sensor; a workstation (80, 72) including a display and operably connected to the sensor and to the tracking system, the workstation having a computer readable recording medium storing a computer program comprising instructions which, when executed by the workstation, cause the workstation to carry out the steps of: a) presenting the location of the tracked sensor on the display and b) generating one or more images including one or more fields for presentation on the display; and a remote control handle releasably connected to the handle for steering the extended working channel and the locatable guide, the remote control handle being in communication with the workstation and enabling a clinician to manipulate the one or more fields generated by the program and presented on the display. a bronchoscope having a working channel; an extended working channel sized for insertion into the working channel of the bronchoscope and to receive one or more instruments therethrough; a magnetic field generator; a locatable guide for insertion into the extended working channel, the guide including an electromagnetic sensor for sensing the magnetic field generated by the magnetic field generator and lockable into position such that the sensor extends a desired distance beyond the distal tip of the extended working channel; a handle, connected to and forming a proximal end of the extended working channel, that can be manipulated to steer the extended working channel and the locatable guide; a tracking system for tracking the sensor; a workstation (80, 72) including a display and operably connected to the sensor and to the tracking system, the workstation having a computer readable recording medium storing a computer program comprising instructions which, when executed by the workstation, cause the workstation to carry out the steps of: a) presenting the location of the tracked sensor on the display and b) generating one or more images including one or more fields for presentation on the display; and a) presenting the location of the tracked sensor on the display and b) generating one or more images including one or more fields for presentation on the display; and a remote control handle releasably connected to the handle for steering the extended working channel and the locatable guide, the remote control handle being in communication with the workstation and enabling a clinician to manipulate the one or more fields generated by the program and presented on the display.
