Implant, Intragastric For Morbid Obesity
Unknown
The Intragastric Implant for Morbid Obesity is a device surgically or endoscopically placed within the stomach to occupy space and reduce the effective gastric volume, thereby promoting satiety and limiting food intake as a treatment for morbid obesity. It is classified as a Class 3 (highest risk) device under FDA regulations, requiring Premarket Approval (PMA) due to the risks of gastric injury, obstruction, and other serious complications associated with long-term intragastric placement. The product code is LTI; no regulation number or specific medical specialty code is on file. This device carries the implant flag, as it is placed within the body for an extended period.

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.
