Over-The Counter Indications: Local management of superficial wounds, minor burns, abrasions and lacerations. Prescription Indications: Silverlon® Wound Contact, Burn Contact Dressings are indicated for use up to 7 days for partial and full thickness wounds including traumatic wounds (donor and graft sites, incisions), first and second degree thermal burns, as well as dermal ulcers (stage I-IV pressure sores, venous stasis ulcers, diabetic ulcers), vascular access or peripheral IV sites, orthopedic external pin sites and wound drain sites. Silverlon® Wound Contact, Burn Contact Dressings are indicated for use up to 7 days for decontaminated stable unroofed first and second degree mustard-induced vesicant injuries not requiring skin grafting. Silverlon® Wound Contact, Burn Contact Dressings are 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® Wound Contact, Burn Contact Dressings may help reduce the risk of wound infection and support the body's healing process. Silverlon® Wound Contact, Burn Contact Dressings may be used for the management of painful wounds. Silverlon® Wound Contact, Wound Burn Dressings are a non-adherent wound contact layer that reduces pain during dressing changes and evaporation of moisture in the dressing may soothe the wound. ## Device Story Sterile, porous, non-adherent knitted nylon dressing plated with 99% elemental silver oxide; functions as primary wound contact layer under secondary dressings (foam, gauze). Moisture activates silver ions; ions kill bacteria within dressing; provides antimicrobial barrier; permits oxygen/fluid passage. Used in clinical or home settings; applied by healthcare providers or patients. Non-adherent design reduces pain during dressing changes; moisture evaporation soothes wound. Supports healing by protecting wound bed from foreign objects and reducing infection risk. ## Clinical Evidence No clinical studies conducted. Non-clinical GLP animal study (165 Gottingen minipigs) evaluated efficacy on sulfur mustard-induced vesicant injuries. Primary endpoint: histopathology composite score at day 46. Results demonstrated non-inferiority to standard of care for moderate partial thickness (mean score 0.36 higher) and superficial thickness (mean score 0.01 higher) injuries. No device-related adverse events reported. ## Technological Characteristics Single layer knitted nylon fiber substrate plated with 99% elemental silver oxide. Porous, non-adherent form factor. Antimicrobial effect via silver ion release activated by moisture. Permeable to oxygen and fluids.

Summary of Bench Testing No bench studies were conducted to support this premarket notification. #### 4.13. Summary of Animal Testing A GLP nonclinical study was conducted comparing use of the subject device and standard of care on vesicant-induced sulfur mustard injuries in 165 Gottingen minipigs. Superficial partial thickness (SD) and moderate partial thickness (DD) depth wounds were induced by sulfur mustard vapor followed by wet-to-wet debridement 48 hours post-injury and daily thereafter for 7 days. The wounds were then covered for 30 days with either the subject device or standard of care followed by 7 days of no wound coverage. The primary endpoint for the study was the histopathology composite score (total score of up to 15) of dermal wounds obtained at the end of the study (Study Day 46). The non-inferiority margin for the total histopathology score is 1.5 (or 10% of maximum possible score). In the DD depth injuries, those covered with the subject device had a mean composite histopathology score 0.36 points higher than those covered with standard of care. In the SD depth injuries, those covered with the subject device had a mean composite histopathology score 0.01 points higher than those covered with standard of care. Dressing moistening was performed three times daily with the subject device and once daily with standard of care. The study demonstrated that the Silverlon Wound Contact, Burn Contact Dressing is non-inferior to standard of care when it is changed every 7 days on moderate partial thickness depth decontaminated stable unroofed mustard-induced vesicant injuries not requiring skin grafting on Gottingen minipigs. The study also demonstrated that the Silverlon Wound Contact Burn Contact Dressing is noninferior to standard of care when it is changed every 4 days on superficial thickness depth decontaminated stable unroofed mustard-induced vesicant injuries not requiring skin grafting on Gottingen minipigs. There were no device-related adverse events during the study. The results of this study demonstrated that the new indication does not raise different questions of safety and effectiveness and does not significantly increase any concerns of safety or effectiveness in comparison to use of the wound dressings on the other specified burn types in the predicate labeling. #### Summary of Clinical Testing 4.14. No clinical studies were conducted to support this premarket notification. #### Substantial Equivalence 4.14. {7}------------------------------------------------ Based on the information presented above and further detailed within this premarket notification, Silverlon Wound Contact, Burn Contact Dressings are substantially equivalent to the predicate device. Silverlon Wound Contact, Burn Contact Dressings have the same intended use and same technological characteristics as the predicate device, and do not raise different questions of safety or effectiveness in comparison to the predicate device. --- **Source:** [https://fda.innolitics.com/device/K190343](https://fda.innolitics.com/device/K190343) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
