Abstract
A tracheal tube (40) or laryngeal mask has a sealing cuff (41, 2) with a surface covered by a brush-like material (44, 24) provided by closely-packed fibers (25) between 1 mm and 5 mm in length. The brush-like surface (44, 24) may be provided by coating the surface with an adhesive and using an electrostatic charge to draw fibers (25) to adhere to the adhesive.
