A multi-layer inflatable balloon cuff may be adapted to seal a patient's trachea when associated with an endotracheal tube. The outer layer and the inner layer of the balloon cuff may have different material properties that may enhance a cuff's mechanical pressure seal by reducing wrinkles or folds that may form against a patient's tracheal walls.
