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.

Abstract: The present disclosure provides for an endoscopic apparatus. The apparatus may include a sheath. The sheath may include a first tube concentrically nested within a second tube. The apparatus may further include a laser fiber disposed in the sheath and movable therein along a longitudinal axis of the sheath. The sheath may be actuable to form a first bend by relative axial translation between the first tube and the second tube. Advancing movements of the laser fiber may cause a distal tip of the laser fiber to project out of a distal end of the sheath; and retreating movements of the laser fiber may cause the distal tip of the laser fiber to retract towards the distal end of the sheath.

Abstract: The present disclosure provides for an endoscopic apparatus and methods. The apparatus may include a steerable sheath, a control wire disposed within the steerable sheath, and a basket disposed on the control wire. The steerable sheath may be actuated to form a bend, advancing movements of the control wire may cause the basket to project out of the steerable sheath and expand, and retreating movements of the control wire may cause the basket to retract into the steerable sheath and contract.
