The addition of the new devices complement the previously FDA cleared Vent-Os device for maxillary sinus dilation.

The FDA clearance will enable the company to bring the simplicity, patient tolerability and long-term patency shown by the maxillary system to the treatment of frontal and sphenoid sinuses. The new devices will be immediately available in the USA.

“The Vent-Os system is easy to deploy and enables physicians to bring the benefits of minimally invasive sinus dilation to their patients in an office procedure that is highly tolerable under topical or local anesthesia,” said Ed Hepworth, MD, from the Denver Sinus Institute, Denver, Colorado.

“By adding devices for treatment of the frontal and sphenoid sinuses, an expanded group of patients will be able to benefit from this simple, gentle sinus dilation procedure that I plan to use for both early-stage chronic sinusitis patients who have failed medical therapy and patients suffering from recurrent acute sinusitis.”

In the most recent prospective, multi-center clinical study, the Vent-Os Sinus Dilation System demonstrated sustained patency rates out to three months comparable to, or better than, other available sinus dilation techniques.

Previously, in a prospective, multi-center clinical study, the Vent-Os Sinus Dilation System demonstrated the ability to maintain patent maxillary sinus ostia at 12 months in 93 percent of treated ostia.

Unlike balloon dilation devices that use rapid, high-pressure inflation, the Vent-Os Sinus Dilation System is a small, low-pressure, self-expanding insert designed to gently and gradually open the sinus ostia.

The Vent-Os System incorporates the Company’s proprietary osmotic technology, which utilizes the body’s natural mucosal fluids to expand the device before removal. In an office setting, patients are comfortably relocated to the waiting room between placement and removal of the device.

“Our proprietary low-pressure, self-expanding technology has the potential for broad application in sinus disease, and we are pleased that we can now provide ENTs and their patients with effective, long term solutions for several sinus anatomies” said SinuSys Chief Executive Officer Tom Schreck.
