Chronic rhinosinusitis

A simple, easy way to treat Eustachian tube dysfunction

Clear the path. Relieve the pain.

Approximately 4.6% of adults in the United States suffer from patulous and obstructive Eustachian tube dysfunction (ETD).1 

Balloon dilation of the Eustachian tube (BDET) is considered a safe procedure and is proven effective in treating obstructive ETD.2

The NuVent™ Eustachian tube dilation balloon is designed specifically to treat persistent, obstructive ETD.3 With an atraumatic tip, a flexible balloon section, and a simple, easy design, the device is designed to be atraumatic during insertion into the Eustachian tube.3 The tip is designed not to pass through the bony isthmus.3

Learn about patient selection and how the NuVent balloon works to treat ETD.
