摘要：
A device and method for dilating a Eustachian tube of a patient is disclosed. The device includes a guide catheter and a balloon dilation catheter. The balloon dilation catheter has an actuator that prevents injury to the middle ear. The balloon dilation catheter is slidably coupled with the guide catheter through the guide catheter lumen and is fully inserted into the guide catheter lumen when the distal side of the actuator is adjacent to the proximal end of the guide catheter. The method involves advancing the guide catheter and balloon dilation catheter through a nasal passage of the patient to dilate a portion of the Eustachian tube.
