Device Description

Silver nylon strips are multi-layer, sterile, non-adherent, absorbent composite dressings with an attached adhesive tape or pad. The dressings are composed of three distinct layers: Layer 1 is a polymeric silver coated fabric circumferential covered with a uniform layer of metallic silver. Layer 2 is a needle-punched non-woven rayon web that absorbs drainage from the wound site. Layer 3 is a latex free skin adhesive and tape.

AI/ML Overview

The provided document is a 510(k) summary for a medical device called Silverlon® Adhesive Strip. It primarily focuses on demonstrating substantial equivalence to predicate devices and detailing the device's composition, intended use, and a limited set of performance data.

Based on the provided text, here's a breakdown of the requested information:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly define "acceptance criteria" in a quantitative manner as one might expect for a diagnostic or high-performance device. Instead, the performance assessment is qualitative, focusing on biocompatibility and lack of systemic absorption, which are foundational for safety in wound dressings.

Acceptance Criteria (Implied)	Reported Device Performance
Safety:
1. No local cytotoxicity at the wound site (pig model).	The silver nylon strip was tested in a full thickness animal (pig) wound model that showed no local cytotoxicity of the wound site.
2. No systemic absorption of metallic silver or silver ions (pig model).	The silver nylon strip was tested in a full thickness animal (pig) wound model that showed no absorption (to +/- 2.0 PPB) into systemic circulation of metallic silver or silver ions.
3. Biocompatibility (cytotoxicity, sensitization, acute intracutaneous reactivity).	Biocompatibility tests, including cytotoxicity, sensitization, and acute intracutaneous reactivity studies, were conducted on the Silverlon® Island Wound Dressing. The Silverlon® Island Wound Dressing is identical to the silver nylon strip in composition, and these results were deemed applicable. All tests were performed in accordance with Part-10993 of the International Standard Organization (ISO) Standard (Biological Evaluation of Medical Devices) by North America Science Associates, Inc. (NAmSA). The studies indicated that the device is safe for its intended use.
Functionality (Implied based on device description):
1. Microbial barrier.	The silver surface "provides an effective microbial barrier and protection of the dressing against microbial contamination."
2. Permits passage of wound fluids and is absorbent.	"Permit the passage of wound fluids, are absorbent" (Layer 2 is a needle-punched non-woven rayon web that absorbs drainage).
3. Permits passage of oxygen.	"The silver plated nylon fabric that comprises the wound contact layer permits the passage of oxygen and fluids to and from the wound."
4. Non-adherent (wound contact layer).	"Silver nylon strips are multi-layer, sterile, non-adherent, absorbent composite dressings..."

2. Sample size used for the test set and the data provenance

Sample Size for Test Set:
- Animal Study: The document refers to "a full thickness animal (pig) wound model." The exact number of animals or wounds is not specified.
- Biocompatibility Studies: These were conducted on the "Silverlon® Island Wound Dressing," and the results were deemed applicable. The sample sizes for cytotoxicity, sensitization, and acute intracutaneous reactivity studies are not specified.
Data Provenance: The studies were conducted by North America Science Associates, Inc. (NAmSA), Northwood, Ohio. The animal study appears to be prospective research conducted specifically for this device or a substantially similar one. The biocompatibility studies were also conducted as part of the safety assessment. There is no mention of country of origin of the data beyond the location of the testing facility.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This type of information is not provided in the document. For biocompatibility and animal wound models, "ground truth" is typically established through standardized laboratory assays and veterinary/pathological assessments, rather than expert consensus in the way it might be for image interpretation.

4. Adjudication method for the test set

This information is not applicable and therefore not provided as the performance data described involves laboratory and animal testing, not human readers interpreting observations that would require adjudication.

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, an MRMC comparative effectiveness study was not done. This device is a wound dressing, not an AI-assisted diagnostic tool, so such a study would not be relevant.

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

No, a standalone algorithm performance study was not done or is not applicable. This device is a physical wound dressing and does not involve any algorithms or AI component.

7. The type of ground truth used

For the animal study: The ground truth for local cytotoxicity and systemic absorption would be established by veterinary/pathological assessment (e.g., histological examination of wound tissue, chemical analysis of blood samples).
For biocompatibility studies: The ground truth would be established by standardized laboratory assays for cytotoxicity, sensitization, and acute intracutaneous reactivity, based on ISO 10993 standards.

8. The sample size for the training set

Not applicable and not provided. This device is a physical product, not a machine learning model, so there is no "training set."

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

Not applicable and not provided. As above, there is no training set for this type of device.

OTC Name:	Silver Strips™
Professional Trade Name:	Silverlon® Adhesive Strip
Common Name:	Silver-nylon adhesive strip
Classification Name:	Wound and burn dressing

10.1.3 Identification of predicate device to which substantial equivalence is being claimed

Silverlon® Adhesive Strip is substantially equivalent with respect to function, intended use, and composition to:

1. Qualtex Island Dressing (K910657);
1. Silverlon® Contact Wound Dressing (K981299).

10.1.4 Device Description

Explanation of how the device functions:

{1}------------------------------------------------

Silver nylon strips are designed to intimately contact the wound as a primary dressing. They provide a microbial barrier, permit the passage of wound fluids, are absorbent, and provide effective protection of the dressing against microbial contamination.

Basic scientific concepts that form the basis for the device:

The silver plated nylon fabric that comprises the wound contact layer permits the passage of oxygen and fluids to and from the wound. The surface of the nylon fibers in silver nyon strips consists of a thin layer of metallic silver containing approximately 1% silver oxide and 99% metallic silver that provides an effective microbial barrier and protection of the dressing against microbial contamination.

Significant physical and performance characteristics of the device design, materials used, and physical properties:

Silver nylon strips are multi-layer, sterile, non-adherent, absorbent composite dressings with an attached adhesive tape or pad. The dressings are composed of three distinct layers:

Layer 1 is a polymeric silver coated fabric circumferential covered with a uniform layer . of metallic silver.
. Layer 2 is a needle-punched non-woven rayon web that absorbs drainage from the wound site.
Layer 3 is a latex free skin adhesive and tape. .

10.1.5 Statement of the intended use of the device, including general description of the conditions the device will mitigate and the patient population for which the device is intended

Professional Indications:

Indicated for vascular access, central, arterial and venous IV sites, IM injection sites, abrasions, lacerations, partial thickness burns, wound drain sites and surgical incisions.

Over-The-Counter Indications:

First aid to help in minor cuts, scrapes, abrasions and burns.

{2}------------------------------------------------

10.1.6 Statement of how the technological characteristics of the device compare to those of the predicate devices

The technological characteristics of the device are substantially equivalent to Qualtex Island Dressing (K910657) as far as the absorbent pad, and the tape backing with release liners. The only physical difference between the Qualtex Island Dressing and the silver nylon strip is the wound contact layer. In the Qualtex Island Dressing this layer is reported to be a "nonadherent net", whereas in the silver nylon adhesive strip this layer is composed of silver-coated nylon. The primary difference between the silver nylon strip and the Silverlon® Contact Wound Dressing is that the silver nylon strip is a composite dressing that contains the Silverlon® Contact Wound Dressing as the layer that comes in contact with the wound.

10.2 Assessment of Performance Data

The silver nylon strip was tested in a full thickness animal (pig) wound model that showed no local cytotoxicity of the wound site and no absorption (to +/- 2.0 PPB) into systemic circulation of metallic silver or silver ions. Biocompatability tests, including cytotoxicity, sensitization, and acute intracutaneous reactivity studies, were conducted on the Silverlon® Island Wound Dressing. The Silverlon® Island Wound Dressing is identical to the silver nylon strip in composition; both are multilayer composite dressings with similar layers. Only the shapes and thickness of the absorbency pad differ. Therefore, the results of biocompatibility tests conducted with the Silverlon® Island Wound Dressing are applicable to the silver nylon strip.

All tests were performed in accordance with Part-10993 of the International Standard Organization (ISO) Standard (Biological Evaluation of Medical Devices) by North America Science Associates, Inc. (NAmSA), Northwood, Ohio. The studies indicated that Silverlon® Island Wound Dressing, and therefore silver nylon strip, is safe for its intended use.
