A tool for assisting a medical professional in inserting an endotracheal tube in the trachea of a patient comprises a relatively rigid rod in the shape of an offset spiral. The tool has a mandrel section, a curved arc section smoothly transitioning from the mandrel section, and a tip section smoothly transitioning from the arc section. The arc section is an arc of a three dimensional spiral, and angularly and spatially offsets the tip section with respect to the mandrel section.
