Intended Use
DURAFIBER Ag is an effective antimicrobial dressing that is intended to provide a moist wound environment for use in the management of partial and full thickness wounds including first and second degree burns. Examples of wounds types which indicated are: - Chronic wounds including diabetic ulcers, leg ulcers, pressure ulcers and . sores (partial & full thickness); - surgical wounds left to heal by secondary intent; . - . traumatic wounds; - wounds that are prone to minor bleeding, such as wounds that have been . mechanically or surgically debrided.
Device Description
DURAFIBER Ag is a non woven dressing made of cellulose and cellulose ethyl sulphonate with silver. The product is an absorbent fibrous dressing that gels on contact with wound fluid. The device provides effective antimicrobial properties intended to reduce or inhibit microbial colonization of the device. The silver is present in the device in the form of silver chloride. Upon contact with wound fluid, silver ions are produced from the dissociation of silver and chloride atoms. The ionic form of silver is the active antimicrobial agent.
More Information

No
The 510(k) summary describes a passive wound dressing with antimicrobial properties based on silver ions. There is no mention of any computational or algorithmic components, let alone AI/ML.

No
The device is described as an antimicrobial dressing for wound management, not a therapeutic device that delivers therapy or treatment directly to a patient beyond wound care.

No

The device description and intended use clearly indicate that DURAFIBER Ag is a wound dressing designed to manage wounds and provide antimicrobial properties, not to diagnose a condition.

No

The device description clearly states it is a non-woven dressing made of cellulose and cellulose ethyl sulphonate with silver, which are physical materials, not software.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a dressing for managing wounds. This is a topical application for treatment, not a test performed on a sample taken from the body to diagnose or monitor a condition.
  • Device Description: The description details the physical composition and mechanism of action of a wound dressing. It doesn't mention any components or processes related to analyzing biological samples.
  • Lack of IVD Characteristics: The text does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing a sample (blood, urine, tissue, etc.)
    • Providing diagnostic information
    • Using reagents or assays
    • Measuring biomarkers

The device is a wound dressing with antimicrobial properties, which falls under the category of a medical device used for treatment and management of external wounds.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The biocompatibility of DURAFIBER Ag dressing has been demonstrated through assessment according to ISO 10993-1: 2003 and appropriate in vivo and in vitro tests have been conducted using product that has been packaged and sterilised. These include cytotoxicity, sensitization, irritation, subchronic toxicity, and genotoxicity. These studies indicated that DURAFIBER Ag dressings are safe for their intended use.

Additionally, the effects of the device on wound healing have been evaluated in an animal model, and it was demonstrated that the device had no deleterious clinical effects compared with standard treatment.

5. Device Classification and Panel

A final classification for "dressing" has not been implemented by the General and Plastic Surgery Devices Panel. At this time, however, classification code FRO is unclassified.

6. Predicate Device

Aquacel Ag (K080383)

The DURAFIBER Ag dressing that is the subject of this submission is substantially equivalent to other legally marketed burn and wound dressings. The DURAFIBER Ag dressing is substantial equivalent to Convatec, Aquacel Ag Wound Dressing (K080383). The subject device has all features and benefits associated with, a fibrous gelling dressing and the added benefit of an antimicrobial dressing.

7. Other Relevant Predicate Device

ACTICOAT Flex 7 (K083113)

The specified silver content of ACTICOAT Flex 7 (K083113) is similar to and slightly higher of that of the subject device DURAFIBER Ag and is used on similar wound types. The device is therefore substantially equivalent in terms of silver content.

8. Performance Standards

No applicable performance standards have been established under Section 514 of the FD&C Act. Biocompatibility tests were done in conformance with relevant requirements of AAMI/ISO-10993. Additional standards applicable to the device include the following: ISO 13485, AAMI/ISO 11137-1, and AAMI/ISO 11137-2.
