Device: ULTRA Silver Dressing (Wound Dressing)

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't explicitly state acceptance criteria in a numerical or statistical sense for wound dressings as one might for an AI device's performance metrics (e.g., sensitivity, specificity). Instead, it relies on demonstrating that the modified device, with changes to non-patient contacting layers, performs equivalently to the predicate device in terms of established performance categories.

Study Description:

The study proving the device meets the "acceptance criteria" (understood as demonstrating substantial equivalence to the predicate device) is a "Summary of Non-Clinical Performance Testing."

Relevant Sections from the document:

• Section 7: SUMMARY OF NON-CLINICAL PERFORMANCE TESTING AS BASIS FOR SUBSTANTIAL EQUIVALENCE
  "Validation activities to support the use of the ULTRA Silver Dressings consisted of four main elements:

  • Biocompatibility Testing
  • Validation of Antimicrobial Effectiveness
  • Sterility Validation
  • Fluid Management Performance
    Testing of the ULTRA Silver Dressings has demonstrated that the wound dressing fulfills prospectively defined performance criteria and that the modification system meets user needs."

• Section 8: SUMMARY OF CLINICAL TESTING AS BASIS FOR SUBSTANTIAL EQUIVALENCE
  "No clinical testing was conducted to support this submission."

• Section 10: CONCLUSIONS DRAWN FROM NON-CLINICAL AND CLINICAL TESTS
  "The similarities in intended use, operational characteristics, and functional technological characteristics between the proposed ULTRA Silver Dressings and the predicate AFM Ultra Ag Dressings lead to a conclusion of substantial equivalence between the proposed and predicate device."

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

No, an MRMC comparative effectiveness study was not performed or mentioned in this document. The device is a "skin protectant" (medical fiber absorbent), and the nature of its testing (biocompatibility, antimicrobial, physical properties) does not typically involve human readers interpreting cases or AI assistance.

6. If a Standalone (algorithm only without human-in-the-loop performance) was done:

This question is not applicable as the InterDry is a physical medical device (textile) and not an AI algorithm. Therefore, "standalone algorithm performance" is not relevant to this submission. The performance tests conducted are inherently "standalone" in the sense that they evaluate the device itself without human intervention in the primary measurement.

7. The Type of Ground Truth Used:

The ground truth for this device's performance is established through:

• Standardized Biocompatibility Tests: These tests have predefined endpoints and acceptance criteria based on established international standards (ISO).

The provided text does not describe a study that proves the device meets specific acceptance criteria in the context of typical medical device performance studies for diagnostic or therapeutic efficacy.

Instead, this document is a 510(k) Summary for a wound dressing, which focuses on substantial equivalence to a previously cleared predicate device. The "performance testing" mentioned is for validation activities rather than a comparative effectiveness or standalone performance study in the way one might expect for a diagnostic AI device.

Therefore, many of the requested sections about acceptance criteria, device performance, sample sizes, ground truth, and expert involvement are not applicable or cannot be extracted from this specific document.

Here's an attempt to answer the questions based on the available information, highlighting where the information is missing or not relevant to the requested structure:

Acceptance Criteria and Device Performance Study for Low Adherent AFM Ag Dressings

The provided 510(k) Summary for the Low Adherent AFM Ag Dressings describes validation activities to support the modified device, rather than a study with explicit acceptance criteria and device performance metrics as would typically be presented for a diagnostic or AI-driven device.

The core of this submission is to demonstrate substantial equivalence to a predicate device (Milliken Silver Wound Dressing, K051445) and to confirm that the modification (addition of a low adherent wound contact layer) does not affect safety and effectiveness.

1. Table of Acceptance Criteria and Reported Device Performance

Missing Information: Precise quantitative acceptance criteria (e.g., specific cytotoxicity thresholds, minimum microbial reduction percentages, or sterility assurance levels as defined in standards) are not detailed in this summary. The "reported device performance" is described qualitatively as "validation conducted" and meeting "prospectively defined performance criteria."

2. Sample Size Used for the Test Set and Data Provenance

This document does not describe a "test set" in the context of a performance study for a diagnostic or therapeutic effect. The validation activities (biocompatibility, antimicrobial effectiveness, sterility) typically involve standardized laboratory tests, for which sample sizes are determined by the specific test methods and regulatory standards (e.g., ISO, ASTM). The document does not provide these sample sizes or data provenance (country, retrospective/prospective) for these lab tests.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

Not applicable. The validation activities for a wound dressing (biocompatibility, antimicrobial effectiveness, sterility) do not involve expert-established "ground truth" in the way a diagnostic imaging study would. Standardized laboratory methods and controls are used.

4. Adjudication Method for the Test Set

Not applicable. No expert adjudication is described or relevant for these types of validation tests.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No. An MRMC comparative effectiveness study is not relevant for a wound dressing and was not conducted or mentioned in this 510(k) summary. This type of study is typically for diagnostic devices, especially those involving human interpretation of data (e.g., radiology AI).

6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This device is a physical wound dressing, not an algorithm or AI system.

7. The Type of Ground Truth Used

The concept of "ground truth" as pathology or outcomes data is not directly applicable here. For the described validation activities:

• Biocompatibility: Ground truth is established by standardized material safety tests and comparison to established safe materials or acceptable toxicity limits (e.g., ISO 10993 standards).
• Antimicrobial Effectiveness: Ground truth is established by laboratory cultures and validated methods for measuring microbial reduction or inhibition (e.g., ATCC strains, established protocols).
• Sterility: Ground truth is established by validated sterilization processes and sterility testing (e.g., USP guidelines, ISO 11137).

8. The Sample Size for the Training Set

Not applicable. This device is a physical wound dressing and does not involve a "training set" in the context of machine learning or AI.

9. How the Ground Truth for the Training Set was Established

Not applicable. As there is no training set, this question is not relevant.

Summary of Device Rationale from the Document:

The 510(k) describes a modification to an already cleared predicate device (Milliken Silver Wound Dressing K051445). The modification is the "addition of a low adherent wound contact layer." The key argument for substantial equivalence is that this modification is "minor and does not affect safety and effectiveness of the device." The "performance testing" (biocompatibility, antimicrobial effectiveness, sterility validation) was conducted to confirm that the modified device continues to meet expected performance criteria, implying these tests re-verified the properties of the device post-modification without necessarily presenting a new comparative efficacy study.

Summary of the Study:

The "study" or "performance testing" described in the 510(k) submission for the Silver Wound Pad primarily consists of two types of laboratory tests:

1. Biocompatibility Testing: Performed in accordance with International Organization for Standardization (ISO) recommendations. The results indicated the device's suitability for its intended use. No specific ISO standards or detailed results are provided.
2. Antimicrobial Testing: Performed to demonstrate efficacy against gram-positive and gram-negative bacteria. The results showed the Silver Wound Pad "provides efficacy" against these bacteria. No specific test methods or quantitative results (e.g., bacterial reduction percentages or zones of inhibition) are mentioned.

The overarching "study" in the context of this 510(k) is the demonstration of substantial equivalence to the predicate device (Smith & Nephew Exu-Dry® Non-Permeable Pad). The biocompatibility and antimicrobial tests served to support the claim that the addition of a silver-based preservative does not negatively impact safety and effectiveness, and indeed provides an additional functional benefit (antimicrobial control) while maintaining overall equivalence in design, function, and intended use as a wound dressing. The acceptance criteria essentially boil down to passing these standard laboratory tests to a level that supports safety and efficacy for the stated intended use, and ultimately, allowing the FDA to determine substantial equivalence.

The provided text describes a 510(k) summary for the "Interdry Textile with Silver" device, which is a skin protectant. The performance testing section mentions "Biocompatibility testing" and "Antimicrobial testing". However, it does not provide detailed acceptance criteria with specific numerical targets, nor does it present a detailed study with a defined sample size, ground truth, or statistical analysis in the way typically expected for an AI/ML device.

It's important to note that K061615 is for a medical textile, not an AI/ML device. Therefore, the questions about AI/ML specific criteria (e.g., test set sample size, experts for ground truth, MRMC study, training set size) are not applicable to this submission. The "study" mentioned here refers to standard biocompatibility and antimicrobial efficacy tests for a medical textile.

Here's an attempt to answer the questions based on the available information, noting the limitations due to the nature of the device:

Acceptance Criteria and Device Performance for Interdry Textile with Silver (K061615)

This 510(k) submission is for a medical textile, not an AI/ML device. Therefore, many of the requested details, particularly those related to machine learning model evaluation, are not applicable. The reported performance relates to the physical and biological characteristics of the textile.

1. A table of acceptance criteria and the reported device performance

The "truth" is whether the material elicits a harmful biological response above acceptable thresholds.
• Ground Truth for Antimicrobial Efficacy: Established by quantitative microbiological assays that measure the reduction in microbial counts when in contact with the material, compared to control samples. The "truth" is the measured inhibition or kill rate of specific microorganisms.

8. The sample size for the training set

• Not applicable. There is no AI/ML model to train for this device.

9. How the ground truth for the training set was established

• Not applicable. There is no AI/ML model to train for this device.

Here's an analysis of the provided text regarding the Milliken Silver Wound Dressings, structured according to your request. Please note that the document is a 510(k) summary for a medical device cleared by the FDA, and as such, it focuses on demonstrating substantial equivalence to predicate devices rather than proving specific device performance against predefined acceptance criteria through a full-fledged clinical study in the way a novel drug or a high-risk AI algorithm might.

This document describes a wound dressing, which is a relatively low-risk device. The "performance testing" described is primarily to support the claim of substantial equivalence and safety, not to establish a precise performance metric like sensitivity or specificity.

Acceptance Criteria and Study Details for Milliken Silver Wound Dressings

1. Table of Acceptance Criteria and Reported Device Performance

Given that this is a 510(k) submission for a wound dressing, the "acceptance criteria" are not framed as specific numerical performance targets like sensitivity/specificity for an AI algorithm. Instead, the acceptance criteria are implicitly that the device is substantially equivalent to legally marketed predicate devices, demonstrating comparable safety and effectiveness.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size:
  • Biocompatibility: Not specified beyond "testing was performed."
  • Full Thickness Wound Healing Study (Swine): The specific number of swine or wounds is not explicitly stated. It mentions "swine in order to characterize the healing process."
  • Antimicrobial Testing (Zone-of-Inhibition): Not specified.
• Data Provenance: The wound healing study was conducted using swine (animal data). Other tests (biocompatibility, antimicrobial) are general lab tests. There is no human clinical data presented in this summary.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications

• Experts: Not explicitly mentioned in the context of establishing "ground truth" for the test results. For the animal study, the microscopic evaluation of irritation would typically be performed by a veterinary pathologist, but their number and qualifications are not specified nor is it described as "ground truth" in the AI sense.

4. Adjudication Method for the Test Set

• Adjudication Method: Not applicable. This document does not describe a process involving human judgment on diagnostic output, but rather laboratory and animal study results.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• MRMC Study: No, an MRMC comparative effectiveness study was not performed or described. This type of study is typically relevant for diagnostic imaging or AI algorithms where human readers interpret results.

6. Standalone Performance (Algorithm Only without Human-in-the-Loop)

• Standalone Performance: Not applicable. The device is a physical wound dressing, not a diagnostic algorithm. Therefore, "standalone performance" in the context of AI is not relevant. The device implicitly performs its function (antimicrobial barrier, wound healing support) "standalone" without human-in-the-loop interaction for its primary function once applied.

7. Type of Ground Truth Used

• Ground Truth: The "ground truth" here is based on biological outcomes (wound healing, non-irritation) and laboratory measurements (antimicrobial activity, biocompatibility metrics).
  • For the wound healing study: The observation that "All wounds appeared to heal without complication" and microscopic findings that "the test articles were considered nonirritant" serve as the "ground truth" for the dressing's impact on healing in the animal model.
  • For antimicrobial activity: The "zone-of-inhibition" results directly measure the antimicrobial efficacy, serving as ground truth for that specific property.
  • For biocompatibility: The results from ISO-compliant tests establish the biological safety.

8. Sample Size for the Training Set

• Training Set Sample Size: Not applicable. This is a physical device, not an AI algorithm requiring a training set.

9. How the Ground Truth for the Training Set Was Established

• Training Set Ground Truth Establishment: Not applicable, as there is no training set for a physical wound dressing.
