A guide for an endotracheal tube has an outer sheath of a flexible plastics within which is embedded a bendable rod. The rod is of a metal, such as a copper-plated, zinc-iron alloy and is crimped with a series of indentations along opposite sides so as to give it a preferential plane of bending including the center lines of the indentations. The sheath is a hollow tube opening at both ends through hollow plugs. |
