Intended Use

BIONECT® Hydrogel Gauze Pads are indicated for the dressing and management of partial to full thickness dermal ulcers (pressure sores, venous stasis ulcers, arterial ulcers, diabetic ulcers), wounds including cuts, abrasions, donor sites, and post-operative incisions, irritations of the skin, and first and second degree burns.

Device Story

BIONECT® Hydrogel Gauze Pads consist of sterile cotton gauze impregnated with a hydrogel composed of sodium hyaluronate and purified water. The device is applied topically to wounds to provide a soothing, moist environment supportive of healing. It functions as a non-interactive wound and burn dressing. It is intended for use in clinical settings for the management of various dermal wounds and burns. The device does not accelerate healing or epithelization and is not a permanent dressing or artificial skin.

Clinical Evidence

Clinical experience includes 16 clinical trials (13 controlled) involving approximately 430 patients with various ulcers and burns, demonstrating safety for the intended use. Biocompatibility testing (cytotoxicity, dermal irritation, and sensitization) was performed on the bulk hydrogel solution per ISO-10993 standards.

Technological Characteristics

Sterile cotton gauze pads impregnated with sodium hyaluronate and purified water hydrogel. Sodium hyaluronate acts as a polysaccharide biopolymer to increase gel viscosity. Non-interactive dressing. Biocompatibility testing performed per ISO-10993.

Indications for Use

Indicated for dressing and management of partial to full thickness dermal ulcers (pressure, venous stasis, arterial, diabetic), wounds (cuts, abrasions, donor sites, post-operative incisions), skin irritations, and first/second degree burns. Not for third degree burns.

## 10.1.3 Identification of predicate device to which substantial equivalence is being claimed

BIONECT® Hydrogel Gauze Pads are substantially equivalent in function and intended use to the following cleared non-interactive wound and burn dressing: BIONECT® Hydrogel.

#### 10.1.4 Device description

Explanation of how the device functions: BIONECT® Hydrogel Gauze Pads, since they contain a hydrogel, provide a moist wound environment that is supportive to wound healing.

{1}------------------------------------------------

# fidia Pharmaceutical Corporation

Basic scientific concepts that form the basis for the device: BIONECT® Hydrogel Gauze Pads, since they are a hydrogel dressing, provide a soothing, moist environment that is supportive to wound healing.

Significant physical and performance characteristics of the device such as device design, materials used, and physical properties: BIONECT® Hydrogel Gauze Pads are sterile cotton gauze pads impregnated with a hydrogel that is prepared from sodium hyaluronate and purified water to form a hydrogel dressing. Sodium hyaluronate is a polysaccharide biopolymer that can increase the viscosity of the gel. BIONECT® Hydrogel Gauze Pads, since they are a hydrogel dressing, provide a soothing, moist environment that is supportive to wound healing.

## 10.1.5 Statement of the intended use of the device, including general description of the conditions the device will mitigate and the patient population for which the device is intended

BIONECT® Hydrogel Gauze Pads are indicated for the dressing and management of partial to full thickness dermal ulcers (pressure sores, venous stasis ulcers, arterial ulcers, diabetic ulcers), wounds including cuts, abrasions, donor sites, and post-operative incisions, irritations of the skin, and first and second degree burns.

These indication statements are not substantially different from the predicate device identified in Section 10.1.3.

## 10.1.6 Statement of how the technological characteristics of the device compare to those of the predicate device

The technological characteristics of the device such as occlusion, bioburden level, and moist wound healing are not different from the predicate device cited.

#### Assessment of performance data 10.2

In vitro and in vivo biocompatibility testing (cytotoxicity, dermal irritation, and dermal sensitization tests) has been performed on the bulk solution that impregnates BIONECT® Hydrogel Gauze Pads in accordance with FDA recommendations. These tests all

Dear Dr. Fiorentini:

We have reviewed your Section 510(k) notification of intent to market the devices referenced above and we have determined the devices are substantially equivalent (for the indications for use stated in the enclosures) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act). You may, therefore, market your devices subject to the general controls provisions of the Federal Food, Drug, and Cosmetic Act (Act) and the following limitations:

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

{4}------------------------------------------------

#### Page 2 - Roberto Fiorentini, M.D.

If your devices are classified (see above) into either class II (Special Controls) or class III (Premarket Approval) they may be subject to such additional controls. Existing major regulations affecting your devices can be found in the Code of Federal Regulations (CFR), Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practices (GMP) for Medical Devices: General GMP regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your devices in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your devices as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your devices to a legally marketed predicate device results in a classification for your devices and thus, permits your devices to proceed to the market.

If you desire specific advice for your devices on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at [phone]. Additionally, for questions on the promotion and advertising of your devices, please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
