Abstract: The endoscope herein described has a unique steering capability allowing the highly flexible distal end of the shaft of the device to be moved to a full range angular positions without rotating the device on its long axis, thus enabling the device to be steered within the cavity of interest. The relative lengths of the control cables used to move the distal end of the bendable shaft can be changed whenever the flexible or malleable shaft is to be re-shaped to a new configuration thus preventing the distal end or the steering mechanism from assuming an undesired angular position. When used as an endotracheal device, a novel tongue retractor is described which forms an internal conduit, allowing passage of the bendable shaft of the endotracheal intubation device and an endotracheal tube therethrough. Methods for performing a tracheal intubation and changing the relative lengths of the cables are disclosed.
