This invention can be used in three different ways for patients who are lying down in bed or on the operating table. First it facilitates the endotracheal intubation, secondly it facilitates the spontaneous breathing of obese patients and thirdly it assists the spontaneous inspiration and expiration in a non-invasive way. This invention device is positioned under the patient before he is asleep without disturbing him. It allows a gradual elevation of the lower and or upper thorax, a gradual elevation of the head giving a flexion of the neck and a gradual hyperextension of the head. After intubation the position is returned to normal without need for removing the invention device. This invention elevates the spinal column and therefore the thorax is no more compressed and the ribs can move free. Inspiration requires less force and the patient can be breathing easier even when lying down. In this invention the spinal column elevation can also be inflated in a synchronized way with the respiration of the patient. During inspiration the spinal column is elevated, facilitating the inspiration. During expiration the elevation is lowered, facilitating the expiration. The work of breathing is reduced for the patient resulting in larger minute volume ventilation or less oxygen consumption.

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.

An oral airway includes a first component having a first guiding surface and a second component having a second guiding surface. The first component and the second component are adapted to be removably coupled together such that the first guiding surface and the second guiding surface collectively define and encompass an interior passage through the oral airway that is dimensioned to direct, for example, a fiber-optic scope or an endotracheal tube extending through the interior passage for tracheal intubation. The first and second components are configured to be decoupled and independently removed from a patient's mouth without disrupting an endotracheal tube that has been extended through the conduit for tracheal intubation. The first and second components may be maintained in coupled disposition by an interlocking mechanical structure. The first and second components also may be maintained in coupled disposition by magnetism.

The NaPier tube is a self-expanding port-access tube for insertion into body passages. A NaPier tube is typically used with an endoscope disposed within the lumen of an unactivated tube to enable visual navigation to place the tube in a passage. A NaPier tube comprises a shape-memory element, wall material, and a removable sheath. A tear-away, removable sheath maintains the shape-memory element in a compressed state. Upon placement of the distal end of a NaPier tube in the target location in a passage, the sheath is ruptured and removed through the port and the shape-memory element expands to its memorized geometries. Embodiments of the NaPier tube are adapted by length and memorized dimensions for endotracheal intubation and for port-access procedures, such as endoscopic surgery.
