Abstract
A variable size endotracheal tube (VSET) is described for use in intubation of a body lumen. The VSET includes a flexible, tubular member with a distal end and a proximal end. The proximal end includes a tube adapter configured to be coupled to a gas source. In one embodiment, a stent-like infrastructure runs substantially longitudinally along the length of the tubular member. The stent-like infrastructure is configured to variably expand a cross-section of the inner surface of the tubular member along substantially the full length of the tubular member. Furthermore, the stent-like infrastructure is arranged to maintain the variable expansion of the cross-section to substantially prevent stenosis of the body lumen, while the body is intubated.
