(240 days)
Rx Only (Pad and Ribbon Configurations)
Under the supervision of a healthcare professional, ALGS2 Ag Alginate Wound Dressing may be used for the management of acute and chronic, partial and full thickness wounds including pressure ulcers, leg ulcers, diabetic foot ulcers, surgical wounds, traumatic wounds, partial thickness burns.
For Over-the-Counter use (Pad Configuration)
ALGS2 Ag Alginate Wound Dressing may be used for
. Minor Abrasions
Minor Lacerations
. Minor cuts
. Minor scalds and burns
ALGS2 Ag Alginate Wound Dressing is a soft, highly absorbent, sterile, single use, nonwoven (Rx version pad or ribbon, OTC version pad only) dressing composed of calcium alginate and 0.95% ionic silver which allows for a maximum of 18 mg of silver for a 4 inch x 4 inch dressing. The silver present in the dressing is to prevent or inhibit growth of bacteria within the dressing absorbs wound fluid and creates a soft and cohesive gel which conforms to the wound surface and assists in maintaining a moist environment. The ALGS2 Ag Alginate Wound Dressing helps maintain a moist wound environment which is conducive to wound healing.
The ALGS2 Ag Alginate Wound Dressing is individually packaged in foil pouches and terminally sterilized by gamma radiation.
This document describes a 510(k) submission for the "ALGS2 Ag Alginate Wound Dressing" and its substantial equivalence to a predicate device, the "ALGS6 Ag Alginate Wound Dressing." The focus of the provided text is on demonstrating this equivalence through comparison of technological characteristics and performance testing related to biocompatibility and bench tests. Crucially, this submission does not involve an AI/ML powered device, nor does it detail a clinical study with human readers assessing AI performance.
Therefore, I cannot fulfill the request to describe acceptance criteria and a study proving device performance in the context of AI/ML. The provided information relates to a medical device (wound dressing) and its physical, chemical, and biological properties, not an AI algorithm.
Specifically, the document focuses on:
- Device Description: ALGS2 Ag Alginate Wound Dressing is a sterile, single-use, nonwoven dressing composed of calcium alginate and 0.95% ionic silver.
- Indications for Use: For management of acute and chronic, partial and full thickness wounds (Rx Only) and minor abrasions, lacerations, cuts, scalds, and burns (OTC).
- Predicate Device: ALGS6 Ag Alginate Wound Dressing (K172570) from the same manufacturer.
- Technological Characteristics Comparison: A detailed table comparing parameters like Indications for Use, Intended Use, Device Design, Mechanism of Action, Antibacterial Material/Activity, Hydrophilic Material, Method of Affixation, Wear Time, Integral Removal, Single Use, Sterilization, and Primary Packaging. All parameters are deemed "Substantially Equivalent."
- Performance Data: This section lists biocompatibility and bench testing performed.
- Biocompatibility Testing: Lists tests like Cytotoxicity, Sensitization, Irritation, Pyrogenicity, Acute Systemic Toxicity, Subchronic Toxicity, Implantation Effects (Wound Healing Study), and Bacterial Endotoxins Test. Methods for each are cited (e.g., ISO 10993 series, USP).
- Performance Testing - Bench: Lists tests like Weight/Dimensions, Absorbency, Moisture Content, Acidity, Silver Content, Heavy Metal Analysis, and Evaluation of Antibacterial Effectiveness.
None of the requested components for an AI/ML study (e.g., test set sample size, data provenance, expert ground truth, MRMC study, standalone performance, training set details) are relevant to this 510(k) submission as it is for a traditional medical device (wound dressing), not an AI-powered one.

Dear Albert Rego:
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/cdrb/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.
{1}------------------------------------------------
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).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
