System and device for visualization of an enclosed space

1. A stylet comprising:

a) an elongated stylet having a malleable rod removably housed within the stylet, the stylet having an opening in a manually operable actuator at a proximal end of the stylet for insertion and removal of the malleable rod, the stylet further comprising:

i) a flexible proximal portion having a predetermined shape defined by the malleable rod when inserted in the stylet; and

ii) a distal tip, the distal tip being capable of deflection when the malleable rod is inserted in the flexible proximal portion of the stylet; and

b) the manually operable actuator configured to receive a force from a user at the proximal end of the stylet to control a deflection angle of the distal tip when the malleable rod is inserted in the flexible proximal portion of the stylet,

wherein the stylet and the malleable rod are configured to engage each other upon insertion of the malleable rod into the flexible proximal portion of the stylet, and

wherein, the stylet and the malleable rod are configured such that upon withdrawal of the malleable rod from the flexible proximal portion of the stylet, the malleable rod traverses a cross sectional plane of the actuator that is perpendicular to the malleable rod.

2. The stylet of claim 1 , wherein the stylet further comprises an image acquisition element, an illumination source, or combination thereof.

3. The stylet of claim 2 , wherein the stylet comprises an image acquisition element and an illumination source.

4. The stylet of claim 3 , wherein the stylet further comprises a display monitor in electronic communication with the image acquisition element.

5. The stylet of claim 1 , further comprising an endotracheal tube operably coupled to the stylet.

6. A method of intubating a patient comprising intubating the patient with the stylet of claim 1 , in combination with an endotracheal tube.
