The Propel Contour sinus implant (formerly called the Nova implant) is a second-generation, bioabsorbable steroid-releasing sinus implant developed by the manufacturer of the FDA-approved Propel and Propel Mini steroid-releasing implants. The Propel Contour sinus implant is comprised of a bioabsorbable co-polymer, and contains 370 µg of mometasone furoate, an anti-inflammatory steroid. The implant is designed to accommodate the size and variability of the frontal or maxillary sinus ostium after surgical enlargement. The implant is inserted by a physician under endoscopic visualization using a proprietary delivery system to access the frontal or maxillary sinus ostium and deploy the implant.
