It functions as a surface dressing for intact, uninfected scarred skin. The device provides physical, thermal, and mechanical properties similar to silicone gel sheet dressings. It can be worn with or without secondary fixation (e.g., bandages, tape, wraps). The dressing is applied by the patient or clinician to the scar site to reduce firmness, pruritus, pain, and tenderness. It is not intended for wound exudate absorption or contact with open wounds/body fluids. ## Clinical Evidence Clinical and molecular testing compared hydrogel dressings to silicone dressings. Results showed equivalent clinical improvement in scar firmness, pruritus, pain, and tenderness. Molecular analysis indicated equivalent changes in mRNA levels for IL-8, bFGF, GMCSF (increased), and TGFB and fibronectin (decreased) following treatment with both dressing types. ## Technological Characteristics Hydrogel sheet with polyurethane film backing. Provides physical, thermal, and mechanical barrier properties. Non-adhesive or used with secondary wraps/bandages. Intended for intact, uninfected skin. ## Regulatory Identification Silicone sheeting is intended for use in the management of closed hyperproliferative (hypertrophic and keloid) scars. ## Predicate Devices - Silastic Soft Sheeting ([K894226](/device/K894226.md)) - Cica-Care Silicone Gel Sheet ([K935803](/device/K935803.md)) - NovaGel Sheeting ([K963128](/device/K963128.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

K963128 | {1}------------------------------------------------ # 05 #### 510(k) SUMMARY K981353, Page 2 #### DEVICE DESCRIPTION বাঁ Avogel® is a sheet of hydrogel with a polyurethane film backing. #### INTENDED USE ળી Avogel® is intended for use in the management of hypertrophic scars. ## TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE کے COMPARED TO THE PREDICATE DEVICE The device is indicated for surface dressing of intact and uninfected scarred skin identical to the predicate devices. The device offers user flexibility as it can be worn under a simple bandage, paper tape, ace wrap or flexnet as desired by the patient. The device may be worn without attachment by adhesives or wraps. As with the predicate devices, the barrier function of healed skin is expected to be intact. Avogel® and the predicate devices provide similar physical, thermal and mechanical properties. Clinical and molecular testing has shown equivalent clinical improvement using silicone and hydrogel dressings with reduction in firmness, pruritus, pain and tenderness. Molecular testing showed increased levels of IL-8, bFGF and GMCSF mRNA; while mean TGFB and fibronectin mRNA decreased after treatment with both dressings. Both silicone and hydrogel dressing offered treatment for hypertrophic scars that was monitored at the clinical and molecular level with equivalent outcomes. The limited indication statement of Avocet Polymer Technologies Gel does not raise new issues of safety in comparison to the predicate device. The barner function of treated skin is expected to be intact during Avogel® use. This submission does not claim intended use for wound exudate absorption. Avogel® is not intended to be placed over open wounds. Avogel® is not intended to be placed in direct contact with body fluids (either from eyes, internally or from open wounds). {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the seal of the U.S. Department of Health and Human Services.
