Abstract: A Eustachian tube dilation device adapted for insertion via an ear canal and including a balloon catheter having a sheath and a balloon mounted proximate to a distal end of the sheath; and an introducer having a malleable distal portion and a more rigid proximal portion. The introducer defines a lumen that is capable of slidably receiving the balloon catheter within the introducer and has a distal opening through which the balloon can be extended from the introducer into the Eustachian tube. The Eustachian tube dilation device may further comprise an inflation device. The Eustachian tube dilation device may also incorporate imaging technology and endoscopy. A method of using the Eustachian tube dilation device for dilation of the Eustachian tube via the ear canal is also described.
