Devices, systems, and methods are provided herein for identifying an anatomical location inside a lumen or a space in the body of a subject undergoing endoscopic surgery. A catheter includes a proximal end and a distal end. The distal end includes one or more light emission areas. The shape of the catheter can be determined based on light transmitted from the one or more light emission areas through a wall of a lumen or space within the body of a subject. Also disclosed herein are methods for conducting an endoscopic procedure using any one of the disclosed catheters. These methods facilitate identification of the anatomical location associated with the surgery to aid in the performance various operations, for example, removing anatomic structures or debris from the anatomical location, dilating the lumen or the space, and, for placing a second device. |
