Intended Use
Silverlon™ Direct Pressure (DP) Wound Closure Strips are absorbent antimicrobial barrier dressings. The Over-The-Counter (OTC) indications: Local management of superficial wounds and skin tears and minor lacerations. The Prescription Professional indications: Primary or secondary closure following surgery, supplementary-support to sutures, staples or sealants, wound support following suture removal, and wound sites where suturing would aggravate bleeding.
Device Description
Silverlon™ DP Wound Closure Strips are designed to provide a balanced relief of tensions at the wound edges by exerting a compressive and downward force on the wound surface through the antimicrobial barrier multilaminate composite portion of the strip. Without impairment of microcirculation, the elastasticity of the non latex elastic component provides a stabilizing force to the wound edge reapproximation. The Silverlon™ component provides effective protection of the dressing against microbial contamination. The dressing maintains a moist wound environment which promotes wound healing. The design of the elastic component allows for the wound edges to be pulled together while minimizing the irritation, blistering and skin shearing associated with mechanical trauma. As the patient goes through the activities of daily living, the antimicrobial barrier composite laminate pad experiences minimal motion and therefore minimal disruption of the wound margins. The pattern of the elastic design of the DP portion of the closure strip provides the minimal motion and intimate contact between the antimicrobial barrier laminate and the wound margins as the edema subsides. The design of the relief holes in the elastic non latex elastic component allow: (1) minimum movement of the laminate and the wound edges as the surrounding skin moves; and (2) the physician to vary the compression on the wound surface after the dressing is applied by cutting bands. Silverlon™ DP Wound Closure Strips are multi-layer, sterile, elastic, antimicrobial barrier absorbent composite wound closure strips. The dressings are composed of five distinct layers outlined in Figure 1 below: Layer 1 is a non-adherent wound contact layer that consists of 1 or 4 layers of 0 continuous nylon fiber substrate with a metallic silver surface (Silverlon™). Layer 1, Layer 2, Layer 3, and Layer 4 are sewn together with silver nylon thread that is plated in an identical fashion to the silver nylon utilized to make the Silverlon™ fabric. The silver coating is a uniform 1-micron thick layer that completely covers the nylon. Layer 2 is Delnet P530N Layer 3 is a needle-punched non-woven 8-ounce or 4-ounce rayon wed that absorbs drainage from the wound site Layer 4 is polyurethane film that keeps external contaminants out and maintains a moist wound healing environment. (Note: Layers 2, 3,and 4 are manufactured as a laminate by AET) Layer 5 is a composite laminate of non-woven polyester fabric (5.2, Figure 1) . coated with a skin contact pressure sensitive acrylic adhesive (5.4, Figure 1) backed with a one sided poly coated lay flat release liner and non latex elastic. The pressure sensitive acrylic adhesive H-566, is a hypoallergenic adhesive that meets USP Class 6 standard and satisfies tripartite guidelines for skin contact devices. The non-woven polyester tape is interrupted by a section of elastomeric non latex (5.1. Figure 1). Holes are punched out in the non latex elastic (5.3, Figure 1) to allow adjustability of the elastic component of the Silverlon™ DP Wound Closure Strip.

10.1.4 Device Description

Explanation of How the Device Functions: Silverlon™ DP Wound Closure Strips are designed to provide a balanced relief of tensions at the wound edges by exerting a compressive and downward force on the wound surface through the antimicrobial barrier multilaminate composite portion of the strip. Without impairment of microcirculation, the elastasticity of the non latex elastic component provides a stabilizing force to the wound edge reapproximation.

strip provides the minimal motion and intimate contact between the antimicrobial barrier laminate and the wound margins as the edema subsides. The design of the relief holes in the elastic non latex elastic component allow: (1) minimum movement of the laminate and the wound edges as the surrounding skin moves; and (2) the physician to vary the compression on the wound surface after the dressing is applied by cutting bands.

Basic Scientific Concepts that Form the Basis for the Device: The basic scientific concepts of the Silverlon™ DP Wound Closure Strip are:

. Maintains Antimicrobial barrier Environment:

The surface of the multilaminate composite pad is silver-plated nylon fibers similar to the silver nylon in the Silverlon™ Contact Wound Dressing. The silver-plated nylon consists of a thin laver of autocatalytic plated metallic silver (1 micron) containing approximately 99% metallic silver and 1% silver oxide to provide an antimicrobial barrier against a broad range of microbial species. The silver provides effective protection of the dressing against microbial contamination.

. Maintains Moist Wound Environment:

Moist wound healing is provided by the 8 ounce and 4 ounce rayon pad laminate with polyurethane film. The polyurethane film provides a semipermeable membrane allowing the passage of oxygen but partially restricting the passage of fluids.

3

  • . Maintains Dynamic Lateral and Downward Compression of the Wound Margins:
    The design of the elastic component allows for lateral and downward compression of the wound margins. The wound edges are pulled together while minimizing the irritation, blistering and skin shearing associated with mechanical trauma. The elastic design provides balanced relief of tensions at the wound edges by exerting a compressive and downward force on the wound surface. The direct pressure (DP) elastic design provides minimal motion and intimate contact between the antimicrobial barrier laminate and the wound margins. This is most noticeable as the edema surrounding the wound edges subsides. The design of the relief holes in the elastic non latex component allow: (1) minimum movement of the laminate and the wound edges as the surrounding skin moves; and (2) the physician to vary the compression on the wound surface after the dressing is applied by cutting bands.

Significant physical and performance characteristics of the device such as device design, materials used, and physical properties: Silverlon™ DP Wound Closure Strips are multi-layer, sterile, elastic, antimicrobial barrier absorbent composite wound closure strips. The dressings are composed of five distinct layers outlined in Figure 1 below:

allows increased compliance, which allows for movement without stress and reduces irritation, blistering and skin shearing associated with mechanical trauma. The 3M Company, Steri-strip Antimicrobial Skin Closure 510(k) has deleted all references to the specifics of the antimicrobial agent utilized, only that the "antimicrobial has been evaluated for safety in vitro, on animals and on humans." The Silverlon™ Wound Contact Dressing (K981299), is a non-adherent wound contact layer that consists of 1 or 4 layers of knitted continuous nylon fiber substrate with a metallic silver surface (Silverlon™). The layers of Silverlon™ are sewn together with silver nylon thread that is plated in an identical fashion to the silver nylon utilized to make the Silverlon™ knitted fabric. The silver coating is a uniform 1-micron thick layer that completely covers the nylon and provides effective protection of the dressing against microbial contamination.

All three products are supplied sterile. The 3M Company, Steri-strip Antimicrobial b Skin and Genetic Laboratories, Suture Strip™ Wound Closure Strip are used as a primary non-suture skin closure, or as a adjunct to suture closure, or as a reinforcement for wounds after early suture or staple removal. The Silverlon™ Wound Contact Dressing is a nonadhering dressing providing effective protection of the dressing against microbialcontamination.
