## Intended Use

Wound contact layer dressings are indicated to provide covering for the wound bed. For OTC applications, CicaNet* Wound Contact Layer Dressing may be used for the management of minor wounds including Abrasions Skin tears Minor burns and scalds Under the care of a healthcare professional, CicaNet* Wound Coutact Layer Dressing may be used in the management of partial and full thickness wounds including: Leg ulcers Pressure ulcers Second degree burns Surgical wounds Diabetic foot ulcers

## Device Story

CicaNet is an air-permeable, transparent, bi-axially stretched high-density polyethylene net. It functions as a non-adherent wound contact layer to cover the wound bed. Used in clinical settings by healthcare professionals or by patients for OTC minor wound management. The device provides a physical barrier between the wound and secondary dressings, facilitating moist wound management. It does not accelerate healing or act as a permanent dressing.

## Clinical Evidence

No clinical data. Evidence consists of bench testing: cytotoxicity (mouse fibroblast), delayed dermal contact sensitization (guinea pig), primary skin irritation (FHSA guidelines), in vitro hemolysis, and USP systemic toxicity (mouse). All tests confirmed non-toxic, non-irritating, and non-hemolytic properties.

## Technological Characteristics

High-density polyethylene net; bi-axially stretched; air-permeable; transparent; non-adherent. Sterilized via Ethylene Oxide (SAL 10^-6).

## Predicate Devices

- 3M Tegapore™ Wound Contact Material
- DERMANET™ Wound Contact Layer

# Device Description

CieaNet+ Wound Contact Layer Dressing is an air permeable, transparent, bi-axially stretched net constructed of high density polyethylene. This product is used in moist wound management of partial and full thickness wounds.

Wound contact layer dressings are indicated to provide covering for the wound bed.

## Indications for Use

For OTC applications, CicaNet* Wound Contact Layer Dressing may be used for the management of minor wounds including

- Abrasions サ
- t Skin tears
- 용 Minor burns and scalds

Under the care of a healthcare professional, CicaNet* Wound Coutact Layer Dressing may be used in the management of partial and full thickness wounds including:

- . Leg ulcers
- Pressure ulcers 4
- � Second degree burns
- Surgical wounds .
- t Diabetic foot ulcers

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

#### Technological Characteristics:

The CicaNet* Wound Contact Layer Dressing is technologically the same as the substantially equivalent products:

3M Tegapore ™ Wound Contact Material DERMANET™ Wound Contact Layer Conformant 2 ™ Transparent, Non-Adherent, Wound Veil TELFA CLEAR ™ Nonadherent Wound Dressing N-TERFACE @ Interpositional Surfaceing Material

in that all products are an air permeable, transparent, non-adherent wound contact layer.

#### Bio Compatibility

#### Cytotoxicity

A study was conducted using mouse fibroblast cells as the substrate in order to determine the cytotoxicity of CicaNet* Wound Contact Layer Dressing.

Conclusion: Under the conditions of the study, the test article was found to be nontoxic.

#### Contact Sensitization

A study was conducted in the guinea pig to evaluate the potential for delayed dermal contact sensitization of CicaNet* Wound Contact Layer Dressing.

Conclusion: Under the conditions of this study, the test article showed no evidence of causing delayed dermal contact sensitization in the guinea pig.

#### Animal Primary Irritation

CicaNet* Wound Contact Layer Dressing was evaluated for primary skin irritation in accordance with the guidelines of the Federal Hazardous Substances Act (FHSA) Regulations, 16 CFR 1500.

Conclusion: The test article would not be considered a primary irritant to the skin since the empirical score was less than 5.00.

#### Hemolysis Study - In Vitro Procedure (Extraction Method)

CicaNet* Wound Contact Layer Dressing was evaluated to determine whether the presence of any leachable chemicals would cause in vitro red blood cell hemolysis.

Conclusion: The mean hemolytic index for CicaNet* Wound Contact Layer Dressing extract was 0%. CicaNet* Wound Contact Layer Dressing is nonhemolytic.

You may, therefore, market your device subject to the general controls provisions of the Federal Food, Drug, and Cosmetic Act (Act) and the following limitations:

- 1. This device may not be labeled for use on third degree burns.
- 2. This device may not be labeled as having any accelerating effect on the rate of wound healing or epithelization.
- 3. This device may not be labeled as a long-term, permanent, or no-change dressing, or as an artificial (synthetic) skin.
- 4. This device may not be labeled as a treatment or a cure for any type of wound.

The labeling claims listed above would be considered a major modification in the intended use of the device and would require a premarket notification submission (21 CFR 807.81).The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.
