Chronic sinusitis is constant inflammation of the sinus caused by infection or allergy and characterized by facial pain and pressure, nasal congestion, and headaches. When drug treatments fail, functional endoscopic sinus surgery (FESS) is performed to improve airflow within the nose and sinuses, improve drainage, and eliminate diseased tissue.
Unfortunately, up to 30% of sinus surgeries fail due to scarring and recurrent inflammation that closes the nasal openings and requires revision sinus surgery. The market seeks a safe and effective solution that will reduce the need for revision surgery.

The ArchSinus

The ArchSinus developed by STS Medical is designed for post FESS implantation into the ethmoid sinus. The stent  keeps the sinus cavity open up to 28 days, and promotes faster post-surgical healing.
