Abstract
The present invention relates to an illuminated airway product that will allow visualization of the airway of a patient during intubation. The illuminated airway product includes a light source such as an LED disposed at its distal end. The LED shines axially, radially, or in both directions from the airway intubation device. The airway product includes an on-board voltage source. Hence, no additional or external voltage sources or components are necessary to light the device. The airway device may further include one or more lumens or tubes for delivering air, suctioning debris or fluids, delivering medicine, radio-opaqueness, etc. An inflatable cuff may be associated with the endotracheal tube such that collateral flow of air is prevented. An inflation lumen or tube is fluidly coupled to the inflatable cuff. The shape of the endotracheal tube may be adjusted either by use of a stylet or suction trocar made out of a malleable material such as aluminum or by inclusion of a malleable wire within the tube. Kits including a LED lighted endotracheal tube are also provided.
