Vent Cap for a Eustachian Tube Dilation System
First Claim
1. A system for use in dilating a Eustachian tube of a patient, the system comprising:
- a balloon dilation catheter for accessing and treating the Eustachian tube through the nose of a human patient, said the balloon dilation catheter comprising;
an elongate shaft, the elongate shaft having a proximal end and a distal end and an inflation lumen therebetween;
an inflatable balloon positioned at the distal end of said elongate shaft;
a proximal connecter positioned at the proximal end of said elongate shaft, said proximal connector comprising an inflation port in fluid communication with the inflation lumen of the elongate shaft and an in-line port; and
a vent cap attached to said in-line port.

Abstract
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.
