K210135 is an FDA 510(k) clearance for the PROMOGRAN PRISMA Matrix, Small Dressing, PROMOGRAN PRISMA Matrix, Large Dressing. Classified as Dressing, Wound, Drug (product code FRO).
Submitted by 3M Healthcare Business Group (Berkshire, Bracknell Forest, GB). The FDA issued a Cleared decision on February 24, 2022 after a review of 401 days - an unusually long review period, suggesting complex equivalence evaluation.
This device falls under the General & Plastic Surgery FDA review panel. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.
Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind General & Plastic Surgery submissions.
