Abstract
Abstract An endotracheal device includes an outer inflatable cuff and an inner furled cuff for use in emergency conditions. The secondary or furled cuff is formed from a resilient, stretchable polymeric material which allows the cuff to be quickly inflated during use and after use, upon release of the air pressure within, quickly reverts to its tightly wrapped position around the endotracheal tube whereby the endotracheal device can be easily and conveniently removed from the patient. Fluid conduits are provided to inflate both the primary and secondary cuffs independently.
