elastic bougie

Several attempts to force the endotracheal tube over a gum elastic bougie were unsuccessful.

The Eschmann tracheal tube introducer (often incorrectly referred to as a "gum elastic bougie") is specialized type of stylet used to facilitate difficult intubation.

The material of Venn's design was different from that of a gum elastic bougie in that it had two layers: a core of tube woven from polyester threads and an outer resin layer.
