Under the supervision of a health care professional, CoFlex - X AFD® and the CoFlex - X AFD® Pad contact wound dressings are indicated for use in light to heavy exuding partial and full thickness wounds, including decubitus and diabetic ulcers, 1st and 2nd degree burns, and donor sites. These dressings may also be used over debrided and partial thickness wounds. ## Device Story X AFD Dressings are sterile, absorbent, non-adherent primary wound dressings. Construction consists of a polyurethane foam pad containing 1.5% metallic silver-coated nylon fibers (X-STATIC) for antimicrobial preservation, a waterproof/moisture-permeable polyurethane film, and (in most configurations) an integrated latex-free cohesive elastic bandage wrap for fixation. The CoFlex-X AFD Pad configuration lacks the integrated wrap and requires external fixation. Dressings are applied by clinicians or patients to the wound site. The silver-coated fibers act as a preservative and barrier to microbial penetration, as confirmed by strike-through testing. The device maintains a moist wound environment while protecting the wound from external contaminants, facilitating healing of various wound types. ## Clinical Evidence Bench testing only. Biocompatibility testing (cytotoxicity, sensitization, irritation) performed per ISO 10993. Barrier strike-through testing demonstrated prevention of microbial penetration through the outer surface. ## Technological Characteristics Polyurethane foam pad with 1.5% (by weight) X-STATIC metallic silver-coated nylon fibers; waterproof/moisture-permeable polyurethane film; latex-free cohesive elastic bandage wrap (select models). Sterile (EtO). ## Predicate Devices - SILVERSEAL® Contact wound dressing ([K050649](/device/K050649.md)) - Acticoat Moisture Control Dressing® ([K050030](/device/K050030.md)) - Mepilex Ag® Silicone-Coated Dressing ([K061554](/device/K061554.md)) - Polymem® Silver Wound Dressing ([K031307](/device/K031307.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Andover Healthcare, Inc. X AFD Dressings Proprietary Name: Wound Dressings Common/Usual Name: Dressings Classification Name: ### PREDICATE DEVICES 3. - SILVERSEAL® Contact wound dressing (K050649) . - Acticoat Moisture Control Dressing® (K050030) . - Mepilex Ag® Silicone-Coated Dressing (K061554) . - Polymem® Silver Wound Dressing (K031307) � #### 4. DEVICE DESCRIPTION The Andover Healthcare, Inc. X AFD Dressings are offered in four configurations for both over the counter use or prescription use. The dressings are described below: CoFlex - X AFD® foam dressings are comprised of three layers: a polyurethane foam pad containing X-STATIC® metallic silver coated nylon fibers (1.5% by weight, as a preservative) evenly dispersed throughout, a waterproof and moisture vapor permeable polyurethane film layer and a latex-free cohesive elastic bandage wrap which is used to rapidly facilitate the placement and wrapping of the dressing over the wound. They are absorbent, sterile (EtO), flat, flexible and non-adherent. CoFlex - X AFD® dressings are designed to intimately contact the wound as a primary barrier dressing. This barrier, in combination with the X-STATIC® silver (1.5%), as determined by barrier strike through testing, prevents the penetration of microbes through the outer surface and into the dressing. {1}------------------------------------------------ CoFlex - X AFD® First Aid foam dressings are comprised of three layers: a polyurethane foam pad containing X-STATIC® metallic silver coated nylon fibers (1.5% by weight, as a preservative) evenly dispersed throughout, a waterproof and moisture vapor permeable polyurethane film layer and a latex-free cohesive elastic bandage wrap which is used to rapidly facilitate the placement and wrapping of the dressing over the wound. They are absorbent, sterile (EtO), flat, flexible and nonadherent. CoFlex - X AFD® First Aid dressings are designed to intimately contact the wound as a primary dressing. CoFlex - X AFD® Pad foam dressings are comprised of three layers: a polyurethane foam pad containing X-STATIC® metallic silver coated nylon fibers (1.5% by weight, as a preservative) evenly dispersed throughout, a waterproof and moisture vapor permeable polyurethane film layer and a latex-free cohesive elastic backing which will readily adhere to a latex-free cohesive elastic bandage wrap, rapidly facilitating the placement and wrapping of the dressing over the wound. They are absorbent, sterile (EtO), flat, flexible and non-adherent. CoFlex - X AFD® Pad dressings are designed to intimately contact the wound as a primary barrier dressing. This barrier, in combination with the X-STATIC® silver (1.5%), as determined by barrier strike through testing, prevents the penetration of microbes through the outer surface and into the dressing. PowerFlex NL - X AFD® foam dressings are comprised of three layers: a polyurethane foam pad containing X-STATIC® metallic silver coated nylon fibers (1.5% by weight, as a preservative) evenly dispersed throughout, a waterproof and moisture vapor permeable polyurethane film layer and a latex-free cohesive elastic bandage wrap which is used to rapidly facilitate the placement and wrapping of the dressing over the wound. They are absorbent, sterile (EtO), flat, flexible and nonadherent. PowerFlex NL - X AFD® dressings are designed to intimately contact the wound as a primary dressing. #### 5. INTENDED USE For over the-counter use, PowerFlex NL - X AFD® and CoFlex - X AFD® First Aid contact wound dressings are indicated for first aid management of minor abrasions, cuts, scrapes, scalds and burns. Under the supervision of a health care professional, CoFlex - X AFD® and the CoFlex - X AFD® Pad contact wound dressings are indicated for use in light to heavy exuding partial and full thickness wounds, including decubitus and diabetic ulcers, 1st and 2nd degree burns, and donor sites. These dressings may also be used over debrided and partial thickness wounds. {2}------------------------------------------------ #### TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6. The Andover Healthcare, Inc. X AFD contact wound dressings are substantially equivalent in design, function and intended use to several legally marketed wound dressings including: SILVERSEAL® Contact wound dressing (K050649) (Noble Fiber Technology), Acticoat Moisture Control Dressing® (K050030) (Smith and Nephew), Mepilex Ag® Silicone-Coated Dressing (K061554) (Mölnlycke Health Care) and Polymem® Silver Wound Dressing (K031307) (Ferris Manufacturing). All of the Andover Healthcare, Inc. X AFD contact wound dressings and all of the predicate devices are designed to intimately contact the wound as primary dressings. For prescription use, CoFlex - X AFD® and the CoFlex - X AFD® Pad contact wound dressings as well as SILVERSEAL® Contact wound dressing (K050649), Acticoat Moisture Control Dressing® (K050030) and Polymem® Silver Wound Dressing (K031307) are indicated for use in light to heavy exuding partial and full thickness wounds, including decubitus and diabetic ulcers, 1st and 2nd degree burns, and donor sites. These dressings may also be used over debrided and partial thickness wounds. For over the-counter use, PowerFlex NL - X AFD® and CoFlex - X AFD® First Aid contact wound dressings as well as the SILVERSEAL® Contact wound dressing (K050649) are indicated for first aid management of minor abrasions, cuts, scrapes, scalds and burns. In design, the main difference between the predicate devices and three of the four Andover Healthcare, Inc. X AFD contact wound dressings (CoFlex - X AFD®, CoFlex - X AFD® First Aid and PowerFlex NL - X AFD®) is that the predicates require either using tape, a wrap or other method of fixation to secure the dressing in place, while these three X AFD dressings have a latex-free cohesive elastic bandage wrap attached which rapidly facilitates the placement and wrapping of the dressing over the wound. The other dressing is the CoFlex - X AFD® Pad. It consists of only the foam pad dressing portion, without a latex-free cohesive elastic bandage wrap attached, which is the same form as the predicate devices. It requires some method of fixation to secure it in place. (A latex-free cohesive elastic bandage can be used to secure it in place as it readily sticks to the latex-free cohesive elastic bandage backing of the pad.) It is the manner of securing the dressings in place and not the dressings themselves {3}------------------------------------------------ K083133 pg-4 of 4 that are different, and therefore the Andover Healthcare, Inc. X AFD contact wound dressings are substantially equivalent to the predicate devices. All of the Andover Healthcare, Inc. X AFD contact wound dressings and all of the predicate devices contain silver. The polyurethane foam pads in the Andover Healthcare, Inc. X AFD contact wound dressings contain X-STATIC® metallic silver coated nylon fibers (1.5% by weight, as a preservative). These nylon fibers are coated, up to 30% of their weight, with 99.99% pure elemental silver which affords 1.5% total silver (by weight of the foam pad) contained within the X AFD dressing. The amount of silver afforded by the X-STATIC® fibers incorporated into the Noble Fiber Technology SILVERSEAL® Contact wound dressing (K050649) is also 1.5% (by weight of the dressing). Hence the X AFD contact wound dressings are substantially equivalent to the Noble Fiber Technology SILVERSEAL® Contact wound dressing (K050649) in both type and amount of silver in the dressings. Andover Healthcare, Inc. X AFD contact wound dressings are comprised of a polyurethane foam pad containing X-STATIC® metallic silver coated nylon fibers (1.5% by weight, as a preservative) evenly dispersed throughout. Both Mepilex Ag® Silicone-Coated Dressing (K061554) and Polymem® Silver Wound Dressing (K031307) are comprised of foam pads with silver evenly dispersed throughout. Additionally, the silver in both the Andover Healthcare, Inc. X AFD contact wound dressings and the Polymem® Silver Wound Dressing (K031307) is metallic silver. Therefore, X AFD contact wound dressings are substantially equivalent to both the Mepilex Ag® Silicone-Coated Dressing (K061554) and the Polymem® Silver Wound Dressing (K031307). ### PERFORMANCE TESTING 7. The Andover Healthcare, Inc. X AFD Dressings were subjected to biocompatibility test including cytotoxicity, sensitization, and irritation. All tests were performed in accordance with Part-10993 of the International Standard Organization (ISO) Standard (Biological Evaluation of Medical Devices) by North American Science Associates Inc. (NAMSA). The studies indicate that Andover Healthcare, Inc. X AFD Dressings are safe for their intended use. Additionally, barrier strike through testing was performed demonstrating that the Andover Healthcare, Inc. X AFD Dressings prevent the penetration of microbes through the outer surface and into the dressing. {4}------------------------------------------------ Image /page/4/Picture/1 description: The image shows the seal of the Department of Health & Human Services (HHS) of the United States.
