Eustachian catheter, reusable

Definition

A long, flexible tube used for middle ear drainage and/or temporary equalization of the pressure on both sides of the eardrum via insufflation. The distal tip is passed along the floor of the nose and guided into the Eustachian tube; air may be blown from an external bag through the device and into the middle ear. It is typically made of soft metals [e.g., silver (Ag) coated brass], and has a curved distal end with a slightly bulbous tip and a wider funnel-like proximal end with a finger ring to aid manipulation. This is a reusable device.
