Product Code: LFB FDA unclassified

Button, Nasal Septal

Unknown

View full classification →

A nasal septal button is a device inserted into a perforation of the nasal septum to occlude the opening and restore the structural integrity of the septum, often used in patients with septal perforations caused by trauma, surgery, or disease. This device is currently unclassified by the FDA, meaning it has not been placed into a formal device class through the standard classification procedure. It carries product code LFB and no regulation number or medical specialty has been assigned. This device is flagged as an implant, indicating it is placed into the body.

What is a Predicate Device?

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.

Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.

Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
