The fast, gentle way to open your sinuses with a
simple, in-office procedure.

The Vent-Os Sinus Dilation System is a small, low-pressure, self-expanding insert designed to relieve symptoms of sinusitis with a simple procedure. The procedure uses a small capsule-shaped device that is gently placed in your sinus opening. In most patients, the device can be placed in the physician’s office, with local—and often topical—anesthesia. Once in position, it gradually absorbs moisture from the lining of your sinus passage and expands. After an hour, the device is removed and drainage is restored. At the conclusion of the procedure, you may return to normal activities immediately.

How the Vent-Os Sinus Dilation System opens blocked sinuses.


1 | Sinusitis occurs when sinus passages are blocked by swelling or inflammation.

2 | The Vent-Os Sinus Dilation System is a small, capsule-shaped device that your physician temporarily places into the blocked sinus opening.


3 | Once in position, the device absorbs moisture from the sinus passage lining and gradually expands.

4 | The device is then removed, thereby opening the passage, restoring sinus drainage and making it easier for you to breathe. Depending on the severity of your symptoms, your doctor may place and remove the capsule device during your sinus surgery procedure performed in the office.
