Abstract
A system for determining orientation of a guide sheath introduced by a bronchoscope or similar device. An example system includes a display device, a scope device and a guide sheath. The guide sheath includes a window occupying a predefined circumferential sector of a distal end of the guide sheath and a plurality of markings configured to visually indicate location/orientation and/or distance of the window. The plurality of markings includes a plurality of first markings located along a longitudinal center axis of the window and a plurality of second markings located along one or more other longitudinal axes that are radially separated from the longitudinal center axis of the window by more than 45°
