About
S.T. Stent, also known as STS Medical Ltd., is an Israeli startup that has developed a self-expanding, removable nasal implant called ArchSinus. This stent is designed to be inserted into the nasal passage after functional endoscopic sinus surgery (FESS) to prevent common post-surgical complications like inflammation and scarring, which can lead to surgical failure. The stent, made of nitinol, keeps the sinus cavity open for up to 28 days, promoting faster healing and reducing the need for revision surgeries. The device received FDA clearance in 2018.
