S.T. Stent develops a composite, removable sinus stent designed to be placed in the ethmoid sinus following functional endoscopic sinus surgery to keep the cavity open for up to 28 days. The stent improves patient outcomes and reduces the probability of revision surgeries.

The S.T. Stent adapts to the patients anatomy and does not irritate the tissue or migrate. It provides strong, stable support for the sinus walls and is made from biocompatible materials. The stent can be easily removed at any time in a minimally invasive procedure performed in the doctors office without the need for anesthesia.

In 2018 the company was awarded FDA clearance for its sinus stent. S.T. Stent is part of the Trendlines Medical portfolio.
