First Claim
Patent Images
1. A method for dilating a Eustachian tube of a patient, the method comprising:
- advancing a guide catheter through a nasal passage of the patient to position a distal end of the guide catheter at or near an opening of the Eustachian tube of the patient, wherein a distal portion of the guide catheter includes a bend having an angle between 30 and 90 degrees, and wherein the distal portion is more flexible than a proximal portion of the guide catheter;
advancing a guidewire through the guide catheter such that a distal end of the guidewire enters the Eustachian tube;
advancing a dilation catheter over the guidewire to position a dilator of the dilation catheter within the Eustachian tube;
expanding the dilator to dilate the Eustachian tube; and
removing the dilation catheter and guidewire from the patient.

Abstract
Methods and systems for accessing a Eustachian tube of a patient are disclosed. The system includes a guide configured for passing into a nasal passage of the patient to position a distal tip of the catheter at or near a Eustachian tube, the guide having a distal tip with a bend having an angle between 30 and 90 degrees; and a guidewire configured to pass through the guide into the Eustachian tube. A device for providing therapy to the Eustachian tube is passed through the guide.
