On this page
A collagen silver dressing (also called a silver collagen dressing) is a sterile wound dressing that combines a collagen-based material with silver. It is searched for by clinic staff, buyers and students who need to know what the product class is, how the FDA records it, and what to check on a label. This page covers those points and does not cover treatment decisions. For the separate topics see types of collagen dressing and silver wound dressings.
What a collagen silver dressing is
It is a wound dressing in which a collagen-containing matrix is combined with silver in one product. Regulators and device databases do not use “collagen silver dressing” as a formal category. They record such products under broader names, so the same kind of item can appear as “collagen matrix with ORC and silver” in one record and “collagen microscaffold wound dressing” in another.
Who uses it: wound-care clinicians in the settings that stock it, and the buyers and materials staff who source it. The AccessGUDID record for Promogran Prisma MA123 marks that product as prescription use.
How it is built
The name describes two components. The collagen component is an animal-derived protein matrix. The Global Medical Device Nomenclature (GMDN) definition attached to the Promogran Prisma record describes this class as a bioabsorbable animal-derived protein matrix that may include additional compounds such as alginate, and that may be intended to be covered with a secondary dressing. The silver component is stated in the product description itself: the AccessGUDID description for that product reads “Collagen Matrix with ORC and Silver”, where ORC is oxidized regenerated cellulose. For background on collagen sources and forms, see types of collagen dressing; for how silver is carried in a dressing, see antimicrobial wound dressings.
Types and variants
Two FDA-recorded products show how the class is named. The table lists only what each record states.
| Example product | How the record describes it | Record facts |
|---|---|---|
| Puracol Plus Ag Collagen Microscaffold Wound Dressing (Medline Industries) | Collagen microscaffold dressing with silver (Ag) in the name | 510(k) K071552, decision date 04/25/2008, product code FRO |
| 3M Promogran Prisma, model MA123 (3M Deutschland GmbH) | Collagen matrix with ORC and silver | Sterile, single-use, 123 sq cm (19.1 sq in) hexagon, product code FRO, MR Unsafe, prescription use; GUDID record version dated July 21, 2025 |
Naming variants
“Collagen wound dressing with silver”, “silver collagen for wounds” and “silver collagen dressing” all describe the combination of components above. “Collagen foam dressing” is a different phrase: the FDA and GUDID records cited on this page do not define it, so do not assume a foam product contains silver. Check the product’s own label and instructions for use (IFU) for its actual composition.
How the FDA records this product class
Both example products sit under FDA product code FRO, named “Dressing, wound, drug”. The FDA product classification database lists FRO as device class “Unclassified” with the reason “Pre-Amendment”, submission type 510(k), and review panel General and Plastic Surgery. In practice the code name alone does not tell you the composition, so read the individual 510(k) record or GUDID entry.
How to read the record: label and IFU checks
The records cited above support these checks. Each points to a field you can look up rather than a purchasing rule.
- Product code and 510(k) number. Confirm the product appears in the FDA 510(k) database and note the product code (here, FRO).
- Sterile and single-use fields. The Promogran Prisma MA123 GUDID entry marks the device sterile and single-use, with no sterilization required before use.
- MR safety status. The MA123 record lists “MR Unsafe”. Check this field for the exact product in hand.
- Prescription flag. The MA123 record marks the device prescription use.
- Composition and warnings. Composition, indications and contraindications belong to the manufacturer’s IFU. Read them there rather than in a catalogue summary.
Safe use and handling basics
General points only: a dressing marked single-use is not reprocessed or reused, a sterile dressing is handled according to its package labelling, and some products in this class are intended to be covered with a secondary dressing, as the GMDN definition notes. Follow the IFU and the prescriber’s instructions for the individual patient. For wider context see what is a medical dressing and the hydrofiber dressing guide.
Common mistakes
- Treating “collagen foam dressing” and “collagen silver dressing” as interchangeable names.
- Reading product code FRO as a statement about composition; it is a regulatory grouping.
- Assuming one brand’s record (for example size or MR status) applies to another brand.
- Relying on a catalogue summary instead of the IFU for composition and warnings.
FAQ
What is a collagen silver dressing?
A sterile wound dressing that pairs a collagen-based matrix with silver. In FDA-recorded examples it appears as a collagen microscaffold dressing with silver (Puracol Plus Ag, K071552) or a collagen matrix with ORC and silver (Promogran Prisma).
Is a silver collagen dressing the same as a collagen foam dressing?
Not necessarily. “Silver collagen dressing” names the combination of components; “collagen foam dressing” is not defined in the FDA or GUDID records cited here, so the label must be checked.
How does the FDA classify it?
Both documented examples fall under product code FRO, “Dressing, wound, drug”, which the FDA lists as Unclassified (Pre-Amendment), submission type 510(k), General and Plastic Surgery panel.
Is it single-use?
The Promogran Prisma MA123 GUDID record marks it single-use and sterile. Check the record or IFU for any other product.
