Device Description

Antimicrobial Gelling Fiber Dressing with PHMB, is a sterile, non-woven pad or rope composed of carboxymethylcellulose (CMC) fibers, Polyhexamethylene Biguanide (PHMB), Ethylenediaminetetraacetic acid (EDTA), and a reinforcement layer (nylon) for intact removal. The dressing is soft, conformable, and highly absorbent, making it ideal for use with moderate to heavily exuding chronic and acute wounds. As wound exudate containing microorganisms is absorbed and trapped within the dressing, a gel is formed that conforms to the wound bed and anatomical contours, and aids in maintaining a moist wound environment and removing non-viable tissue and slough (autolytic debridement). This is conducive to the natural healing process.
The dressing contains an active ingredient, PHMB. Based on in vitro performance data, the Antimicrobial Gelling Fiber Dressing with PHMB effectively reduces microbial colonization within the dressing for up to 7 days.
The device is presented in a range of both flat/pad (160 g/m 2 and 200 g/m 2 ) and rope (160 g/m 2 ) dressings. The dressings are manufactured consistently using the same raw materials, the same manufacturing lines, follow a similar manufacturing process and utilize the same sterilization route. The sterile dressings are supplied in a range of sizes between 4in 2 (25cm 2 ) to 96in 2 (600cm 2 ).

AI/ML Overview

This document describes a 510(k) premarket notification for a medical device called "Antimicrobial Gelling Fiber Dressing with PHMB." It asserts substantial equivalence to predicate devices, but does not contain information related to software, algorithms, AI performance, or specific acceptance criteria for such a system.

Therefore, I cannot provide the requested information regarding acceptance criteria, study details for AI performance, sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance.

The document details the device's physical properties, indications for use, and a summary of performance testing, which are primarily related to physical characteristics, sterility, biocompatibility, and antimicrobial efficacy of the dressing itself.

Here's the relevant information that is available in the document:

1. Table of Acceptance Criteria and Reported Device Performance:

The document mentions "Performance Testing Summary" but doesn't explicitly list specific acceptance criteria values alongside device performance values in a table format as might be expected for an AI/software device. Instead, it describes general categories of testing and general statements of efficacy.

Acceptance Criteria CategoryReported Device Performance (Summary)
Fluid HandlingIncludes absorbency and shrinkage studies conducted.
Physical StrengthAssessed wet, dry, and bond strength.
Stability TestingConducted.
Package IntegrityConducted.
Broad Spectrum ActivityDemonstrated effective against:
- Methicillin-Resistant S. aureus (MRSA)
- Methicillin Resistant S. epidermidis (MRSE)
- Vancomycin-Resistant E. faecalis (VRE)
- Pseudomonas aeruginosa
- Enterobacter Cloacae
- Klebsiella pneumonia
- Cryptococcus neoformans
- Acremonium strictum
BiocompatibilityBiocompatible (per ISO 10993-1)

2. Sample size used for the test set and the data provenance: Not applicable. This document does not describe a study involving a test set for an AI/algorithm. The performance testing is for the physical medical device.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. This document does not describe a study involving human experts establishing ground truth for an AI/algorithm test set.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is a physical wound dressing and does not involve human readers or AI assistance in an interpretive capacity.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable in the context of an AI/algorithm. For the physical device, efficacy against microorganisms was demonstrated in vitro.

8. The sample size for the training set: Not applicable.

9. How the ground truth for the training set was established: Not applicable.

Dear Kay Mcgrath:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Comparison of Technological Characteristics:

Page 3 of 5

Antimicrobial Gelling Fiber Dressing with PHMB is a multi-layer one piece dressing design incorporating an absorbent non-woven pad or rope composed of carboxymethylcellulose (CMC) fibers, containing 0.3 - 0.9%w/w PHMB. Based on in vitro testing, the PHMB within the dressing has been shown to be effective against gram-positive and gram-negative bacteria, mold, and yeast microorganisms. The dressing is designed to minimize the risk of maceration and damage to newly formed tissue. The dressing, when gelled with exudate is non-adherent to the wound bed and can be easily removed. The Antimicrobial Gelling Fiber Dressing with PHMB can be used under compression. The following table shows a comparison of technological characteristics between the subject device and the predicate and reference devices.
