Acceptance Criteria and Device Performance
The document describes a non-inferiority study performed on Gottingen minipigs. The acceptance criteria are based on a "non-inferiority margin" for a "histopathology composite score."
Acceptance Criteria | Reported Device Performance |
---|---|
Non-Inferiority Margin: 1.5 points (or 10% of maximum possible score of 15) for the total histopathology composite score. The subject device is considered non-inferior if its score is not substantially worse than the standard of care. | Moderate Partial Thickness (DD) Injuries: Mean composite histopathology score for the subject device was 0.36 points higher than standard of care. |
Superficial Partial Thickness (SD) Injuries: Mean composite histopathology score for the subject device was 0.01 points higher than standard of care. | |
Conclusion: | The study demonstrated that the Silverlon Wound Contact, Burn Contact Dressing is non-inferior to standard of care for both moderate and superficial partial thickness mustard-induced vesicant injuries. For DD injuries, this was demonstrated when changed every 7 days, and for SD injuries, when changed every 4 days. |
Explanation of Performance:
Since a higher histopathology score is implicitly better (as the device score was higher than the standard of care and still met non-inferiority), the device performed as well as or slightly better than the standard of care, falling within the pre-defined non-inferiority margin.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI/ML device.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
For the non-clinical tests conducted, the "ground truth" would be established by:
- Biocompatibility: Established ISO 10993 standards and methodologies (cytotoxicity, sensitization, intracutaneous reactivity).
- Antimicrobial effectiveness: Standardized in vitro tests like Kirby-Bauer Standard Antimicrobial Susceptibility Test and ASTM E2315 Time Kill Assay for Antimicrobial Agents Report. The "ground truth" here is the measured bacterial reduction or inhibition according to the test standards.
8. The sample size for the training set
Not applicable. There is no AI/ML model or training set discussed in this document.
9. How the ground truth for the training set was established
Not applicable. There is no AI/ML model or training set discussed in this document.
Summary of the Study that Proves the Device Meets Acceptance Criteria (as per this 510(k) submission):
The "study" in this context is a collection of non-clinical (in vitro) tests and a demonstration of substantial equivalence.
- Biocompatibility Testing: In vitro and in vivo biocompatibility tests were conducted according to ISO 10993 standards, covering cytotoxicity, sensitization, and intracutaneous reactivity. The successful completion of these tests demonstrates the device is biologically safe for its intended use, meeting the implicit acceptance criteria of being non-toxic and non-irritating.
- Antimicrobial Effectiveness Testing: In vitro tests were performed including:
- Accelerated stability testing for antimicrobial effectiveness on samples aged to the equivalent of 5 years.
- Kirby-Bauer Standard Antimicrobial Susceptibility Test.
- ASTM E2315 Time Kill Assay for Antimicrobial Agents Report.
These tests demonstrate the sustained ability of the silver in the dressing to provide an antimicrobial barrier and reduce bacterial growth within the dressing, thereby supporting the proposed indications related to managing infected wounds and reducing infection risk. The acceptance criteria for these tests would be defined by the specific standards, e.g., a certain percentage reduction in bacterial count for the time kill assay, or specific zones of inhibition for Kirby-Bauer. The report states these tests were conducted to demonstrate safety and effectiveness.
- Comparison to Predicate Devices: The core of the K150256 submission is a comparison against legally marketed predicate devices (K023612, K073213, K122817). The "study" concludes that there are "no technological differences" or "minor technological differences that do not raise new questions of safety and effectiveness." This comparison, along with the specified in vitro testing, is the primary means of demonstrating that the device meets the implicit acceptance criteria for safety and effectiveness that were established for the predicate devices.
Key takeaway for this specific document: This 510(k) submission seeks regulatory clearance by demonstrating equivalence to existing devices through non-clinical testing and comparison, rather than through a clinical study with explicit performance acceptance criteria typical for novel devices or AI/ML. No clinical studies were conducted for this premarket notification.

However, it does not contain a detailed study proving that the device meets specific acceptance criteria with performance metrics, sample sizes, ground truth establishment, or expert involvement as typically requested for AI/ML device evaluations.
Instead, the document focuses on regulatory approval (510(k)) based on substantial equivalence to a previously cleared device. The "acceptance criteria" discussed are primarily related to safety and effectiveness demonstrated through biocompatibility and antimicrobial testing, rather than performance metrics for a diagnostic or AI device.
Here's a breakdown of the information available, and what is not present based on your query:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria (from document context) | Reported Device Performance (from document context) |
---|---|
Safety: | |
* Biocompatibility (irritation, sensitization, intracutaneous reactivity) | All tests performed in accordance with ISO 10993 Standard Series for Biological Evaluation of Medical Devices. All materials are biocompatible per irritation, sensitization, and cytotoxicity testing results. |
* No new questions of safety compared to predicate device K122817 | The technological characteristics have not changed from the previously cleared Silverlon® Island Wound Dressing (K122817). The minor changes in design (presence/absence of tape layer) do not influence technological differences, implying no new safety concerns. |
Effectiveness: | |
* Antimicrobial Effectiveness (long-term) | In vitro accelerated stability testing for antimicrobial effectiveness, equivalent to 5 years. |
* Antimicrobial Susceptibility | Kirby-Bauer Standard Antimicrobial Susceptibility Test performed. |
* Antimicrobial Activity (Time Kill) | Microbiological Consultants - ASTM E2315 Time Kill Assay for Antimicrobial Agents Report performed. Layer 1 delivers antimicrobial silver ions, killing wound bacteria and providing an antimicrobial barrier. |
* Maintenance of moist wound healing environment | The moist wound healing environment and control of wound bacteria within the dressing may help reduce the risk of wound infection and support the body's healing process. This dressing absorbs high amounts of wound fluid. |
* Pain reduction during dressing changes | Non-adherent wound contact layer reduces pain during dressing changes; evaporation of moisture in the dressing may soothe the wound. |
* No new questions of effectiveness compared to predicate device K122817 | The technological characteristics have not changed from the previously cleared Silverlon® Island Wound Dressing (K122817). The minor changes in design (presence/absence of tape layer) do not influence technological differences, implying no new effectiveness concerns. The device has the same intended use and technological characteristics as the predicate. |
Information NOT Available in the Document:
The nature of these questions suggests an AI/ML device, which this document does not describe. The information below is thus not found in the provided text.
- Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not applicable as no "test set" for performance evaluation of an AI algorithm is mentioned. The tests are in vitro (antimicrobial, and stability) and in vivo (biocompatibility) laboratory tests.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not applicable. Ground truth for an AI algorithm is not established in this context. The "truth" for biocompatibility is whether the device causes adverse biological reactions; for antimicrobial effectiveness, it's the measured killing of microbes. These are determined by standard laboratory protocols.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable.
- 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 is not an AI/ML device related to human interpretation.
- If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not applicable.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The "ground truth" for the non-clinical tests involved refers to established scientific methodologies and standards. For biocompatibility, it's the absence of toxic or irritating effects as per ISO 10993. For antimicrobial activity, it's the measured reduction in microbial load according to standards like Kirby-Bauer and ASTM E2315.
- The sample size for the training set
- Not applicable. This is not an AI/ML device with a training set.
- How the ground truth for the training set was established
- Not applicable.
Conclusion:
The document is a 510(k) premarket notification letter and summary for a medical dressing, not an AI/ML device. It demonstrates substantial equivalence to a predicate device primarily through technical specifications, biocompatibility testing, and in vitro antimicrobial effectiveness tests. No clinical studies were deemed necessary for this submission. Therefore, most of the specific questions about AI/ML device evaluation criteria (test sets, ground truth experts, MRMC studies, training data) are not addressed by the provided text.

Silverlon® Island Wound Dressing is a multi-layer, sterile, non-adherent, antimicrobial barrier wound dressing.
The Over-The-Counter Indications:
Local management of superficial wounds, minor burns, abrasions and lacerations.
Prescription Indications:
Under the supervision of a healthcare professional Silverlon® Island Wound Dressings are intended for up to 7 day use for wounds such as vascular access or peripheral IV sites, orthopedic external pin sites, surgical wounds (donor and graft sites, incisions), and partial to fill thickness dermal ulcers (stage I-IV pressure sores, venous stasis ulcers, arterial ulcers, diabetic ulcers).
Silverlon® Island Wound Dressing is indicated for the management of infected wounds, as the silver in the dressing provides an antimicrobial barrier that may be helpful in managing these wounds. In addition, the moist wound healing environment and control of wound bacteria within the Silverlon® Island Wound Dressing may help reduce the risk of wound infection and support the body's healing process.
Silverlon® Island Wound Dressing may be used for the management of painful wounds, Silverlor® Island Wound Dressing's non-adherent wound contact layer reduces pain during dressing changes and evaporation of moisture in the dressing may soothe the wound.
Silverlon® Island Wound Dressing is a self-adhesive, elastomeric wound dressing composed of 5 distinct layers (in innermost to outermost order):
• Layer 1 is a non-adherent wound contact layer that consists of a single layer of knitted continuous nylon fiber coated with metallic silver at the rate of 5.05 mg/cm (50.5 g/m²); the silver surface coating is approximately 0.8 – 1.0 µm thick and contains approximately 1% silver oxide.
- · Layer 2 is a polyethylene film used to bond the nylon substrate to the pad layer (Layer 3);
- Layer 3 is a laminate pad with an absorptive capacity of 65 oz/yd² to absorb wound exudate;
• Layer 4 is an apertured high density polyethylene film that bonds the pad to (Layer 5) described below; and,
· Laver 5 is a tape layer comprised of a widely used, commercially available foam tape component with natural color that is coated with a non-latex medical grade acrylic adhesive on the skin-contacting side. The side of the dressing away from the body is covered by a medical grade polyurethane film that is bonded to the foam membrane by an acrylic adhesive.
All materials are biocompatible per irritation, sensitization and cytotoxicity testing results.
Layer 1 delivers antimicrobial silver ions in the dressing when activated by moisture. The silver ions in the dressing kill wound bacteria held in the dressing and provides an antimicrobial barrier to protect the wound bed. This dressing absorbs high amounts of wound fluid and the dressing intimately conforms to the wound surface.
The provided text describes a medical device, the Silverlon® Island Wound Dressing, and its regulatory clearance (K141573) based on substantial equivalence to a predicate device (K122817). This document is a 510(k) summary, which focuses on demonstrating that a new device is as safe and effective as a legally marketed predicate device, rather than providing extensive de novo clinical study data for acceptance criteria.
Therefore, the information requested about acceptance criteria, study details, sample sizes, expert ground truth, adjudication methods, MRMC studies, standalone performance, and training set details for AI/software-based devices is not applicable to this type of regulatory submission and device.
Here's an explanation based on the provided text, addressing why most of the requested information cannot be found:
1. Table of Acceptance Criteria and Reported Device Performance:
- Not Applicable. The 510(k) summary does not set specific numerical acceptance criteria for performance metrics in the way one would for a diagnostic or AI device. Instead, it asserts that the device is "substantially equivalent" to a predicate device. The performance is assessed by confirming that its changed design (a new tape layer) maintains the same technological characteristics and does not raise new questions of safety or effectiveness compared to the predicate.
- The document states: "The technological characteristics have not changed from the previously cleared Silverlon® Island Wound Dressing (K122817)... The minor changes in design do not influence the technological differences, so there are no new questions of safety and effectiveness."
- It also lists "In vitro accelerated stability testing for antimicrobial effectiveness, equivalent to 5 years," "Kirby-Bauer Standard Antimicrobial Susceptibility Test," and "Microbiological Consultants - ASTM E2315 Time Kill Assay for Antimicrobial Agents Report" as tests performed. These tests confirm properties of the dressing (like antimicrobial efficacy and stability), but specific "acceptance criteria" against which these were measured are not explicitly stated in this summary.
2. Sample size used for the test set and the data provenance:
- Not Applicable. This is a medical dressing, not a diagnostic or AI device that would have a "test set" of data in the sense of patient images or clinical data for performance evaluation.
- The tests performed are "in vitro" and "in vivo biocompatibility tests," and "antimicrobial susceptibility tests." The sample sizes for these laboratory tests are not provided in this summary. Data provenance (country of origin, retrospective/prospective) is typically for clinical data, which was not the primary basis of this submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not Applicable. Ground truth, in the context of expert consensus, is relevant for diagnostic devices (e.g., radiologists interpreting images). This device is a wound dressing. The "ground truth" for its properties would be established through laboratory methods and chemical/biological assays, not expert interpretation of clinical cases.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not Applicable. Adjudication methods are used to resolve discrepancies among expert readers in clinical studies, primarily for diagnostic devices. This concept does not apply to the evaluation of a wound dressing.
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 is a physical wound dressing and not an AI device. Therefore, an MRMC comparative effectiveness study involving human readers and AI assistance is entirely irrelevant.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not Applicable. This is a wound dressing, not an algorithm or AI.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- Not Applicable in the typical sense for AI/diagnostic devices. For this wound dressing, the "ground truth" is derived from:
- Biocompatibility testing: Conformance to ISO 10993 standards (cytotoxicity, sensitization, intracutaneous reactivity).
- Antimicrobial effectiveness testing: In vitro accelerated stability, Kirby-Bauer, and ASTM E2315 Time Kill Assay.
- The "truth" is established by these standardized laboratory and material tests, not clinical outcomes data for this specific 510(k) beyond proving substantial equivalence.
8. The sample size for the training set:
- Not Applicable. This is a wound dressing, not an AI device that requires a training set.
9. How the ground truth for the training set was established:
- Not Applicable. As related to point 8, there is no training set for this device.
In summary: The provided document is a 510(k) summary for a wound dressing, which focuses on demonstrating "substantial equivalence" to a predicate device, primarily through non-clinical (laboratory and material) testing and a comparison of technological characteristics. The questions posed are largely relevant to the evaluation of AI/diagnostic software devices and are therefore not addressed in this specific regulatory filing for a wound dressing.

- · Laver 3 is a laminate pad with an absorptive capacity of 65 oz/yd2 to absorb wound exudate;
· Layer 4 is an apertured high density polyethylene film that bonds the pad to the outer polyester fabric described below; and,
· layer 5 is a non-woven, medical grade polyester fabric coated on the skin-contacting side with a self-curing acrylic, pressure-sensitive, medical grade adhesive covered with a silicone-coated (one side) paper liner.
Laver 1 delivers antimicrobial silver ions in the dressing when activated by moisture. The silver ions in the dressing kill wound bacteria held in the dressing and provides an antimicrobial barrier to protect the wound bed. This dressing absorbs high amounts of wound fluid and the dressing intimately conforms to the wound surface.
The provided text is a 510(k) summary for the Silverlon® Island Wound Dressing, a medical device. This document focuses on establishing substantial equivalence to predicate devices rather than providing a detailed study proving performance against specific acceptance criteria in the manner typically seen for algorithmic devices. Therefore, much of the requested information regarding AI/algorithm performance studies is not directly applicable or available in this specific document.
Here's an analysis based on the provided text:
1. A table of acceptance criteria and the reported device performance
The document does not specify quantitative acceptance criteria with reported device performance in the typical sense of a clinical trial for diagnostic or prognostic devices. Instead, the "acceptance criteria" for K122817 are implicitly defined by demonstrating substantial equivalence to predicate devices and meeting established safety and effectiveness standards for wound dressings.
Acceptance Criteria Category | Reported Device Performance (as demonstrated for Substantial Equivalence) |
---|---|
Biocompatibility | Silverlon® Island Dressings have been subjected to independent standard in vitro and in vivo biocompatibility tests, including cytotoxicity, sensitization and intracutaneous reactivity. All tests were performed in accordance with ISO 10993 Standard Series. (Results implied to be acceptable for safety). |
Antimicrobial Effectiveness (Stability) | In vitro accelerated stability testing for antimicrobial effectiveness, equivalent to 5 years, was conducted. (Results implied to be acceptable, demonstrating sustained antimicrobial properties). |
Antimicrobial Susceptibility | Kirby-Bauer Standard Antimicrobial Susceptibility Test and ASTM E2315 Time Kill Assay for Antimicrobial Agents Report were conducted. (Results implied to be acceptable, demonstrating the silver's antimicrobial action). |
Technological Characteristics Equivalence | Silverlon® Island Wound Dressing has substantially the same characteristics as AQUACEL HYDROFIBER WOUND DRESSING AND AG HYDROFIBER DRESSING (K080383) and ACTICOAT FLEX 7 DRESSING (K083113) and has not changed from previously cleared Silverlon® Island Wound Dressing and Silverlon Pad (K984208). Any technological differences do not raise new questions of safety and effectiveness. (Demonstrated through comparison of materials, design, mechanism of action – silver release for antimicrobial effect, absorptive capacity, non-adherence). |
Intended Use Equivalence | The device has the same intended use as the predicate devices: managing various wound types, including infected wounds, painful wounds, surgical incisions, and dermal ulcers, by providing an antimicrobial barrier, absorbing exudate, and maintaining a moist healing environment. (Demonstrated by comparing Indications for Use). |
Safety and Effectiveness (No New Questions) | The technological characteristics and intended use are similar enough to predicate devices that no new questions of safety or effectiveness are raised. This is supported by product specifications, testing (biocompatibility, antimicrobial), and scientific studies. (Conclusion drawn from the submission, leading to substantial equivalence finding). |
2. Sample size used for the test set and the data provenance
The document does not describe a "test set" in the context of an AI/algorithm evaluation. The studies mentioned are primarily pre-clinical (in vitro/in vivo biocompatibility) and in vitro (antimicrobial effectiveness).
- Biocompatibility Studies: Specific sample sizes for cytotoxicity, sensitization, and intracutaneous reactivity tests are not provided, but these are standard tests performed according to ISO 10993. The provenance would be the testing laboratories that conducted these standard tests.
- Antimicrobial Effectiveness: No specific sample size is given for the "accelerated stability testing for antimicrobial effectiveness" or "Kirby-Bauer Standard Antimicrobial Susceptibility Test." These are laboratory-based in vitro studies. The "Microbiological Consultants - ASTM E2315 Time Kill Assay for Antimicrobial Agents Report" would also be an in vitro lab study.
These are not clinical studies with human participants that would typically have a "test set" for performance evaluation in the way requested for AI.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not applicable as there is no mention of a "test set" requiring expert ground truth in the context of an AI/algorithm evaluation in the provided summary. The studies are laboratory-based for material properties and antimicrobial activity.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable as there is no mention of a "test set" requiring adjudication or expert review in the provided summary.
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
No such study was done. This document is for a traditional wound dressing, not an AI-powered device, and therefore MRMC studies or AI assistance are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
No such study was done. The device is a physical wound dressing and does not involve an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the studies mentioned:
- Biocompatibility: Ground truth is established by standard ISO 10993 criteria for material safety.
- Antimicrobial Effectiveness: Ground truth is based on established microbiological testing methods (e.g., Kirby-Bauer, ASTM E2315) and scientific principles of bacterial inhibition/kill.
8. The sample size for the training set
This is not applicable. The device is a physical wound dressing, not an AI/algorithmic device that requires a training set.
9. How the ground truth for the training set was established
This is not applicable for the reasons stated above.
