Abstract: The present disclosure provides an endoscopic apparatus and associated methods. The apparatus may include a steerable tool having a first flexible tube concentrically nested within a second flexible tube. The apparatus may include an end cap disposed on the steerable tool, an image sensor disposed on the end cap, and one or more light sources disposed on the end cap. The apparatus may be configured for accessing a region within a middle ear cavity of a patient. As such, the apparatus may further include a flexible tube, through which the steerable tool may extend, as well as a pre-curved rigid tube, through which the flexible tube may extend, thus allowing the apparatus to be deployed for middle ear access.
