Normothermic Preservation System For Transplantation Of Initially Unacceptable Donor Lungs
Unknown
The Normothermic Preservation System for Initially Unacceptable Donor Lungs is a device used to preserve donor lungs under normothermic conditions for transplantation, enabling the assessment and potential use of lungs that would otherwise be deemed unsuitable for transplant. It is an FDA Class 3 device, requiring Pre-Market Approval (PMA), reviewed by the Gastroenterology and Urology (GU) panel with no assigned regulation number or medical specialty. The product code is PHO, and it carries a life-sustaining flag given its role in organ transplantation. This device is not implanted in the patient.
No 510(k) clearances found for "PHO". Try a different K-number, product code, or device name.
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.
