| Common/Usual Name: | Animal-derived, extracellular matrix wound care product |
| Regulation Name: | Collagen Wound Dressing |

#### DEVICE DESCRIPTION

Cytal" Wound Matrix is composed of porcine-derived extracellular matrix scaffolds, specifically known as urinary bladder matrix. The devices are supplied in single and multi-layer sheet configurations (1 to 8 layers) in sizes up to 10 cm x 15 cm, and can be provided with or without fenestrations in both Ivophilized and vacuum pressed configurations. The device is packaged in double peel-open pouches. The devices are terminally sterilized using electron beam irradiation. The device is intended for one time use.

The technical specifications for the Cytal" Wound Matrix are as follows, depending upon whether the device is fenestrated or unfenestrated:

- . If fenestrated: Device will be provided dry in sheet sizes up to 10 x 15 cm in double sterile barrier packaging. Device will be fenestrated appropriately according to size with parallel slits along the long axis.
- . If unfenestrated: Device will be provided dry in sheet sizes up to 10 x 15 cm in double sterile barrier packaging.

## INDICATIONS FOR USE

Cytal" Wound Matrix is intended for the management of wounds including: partial and full-thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunnel/undermined wounds, surgical wounds (donor sites/grafts, post-Mohs surgery, post-laser surgery, podiatric, wound dehiscence), trauma wounds (abrasions, second-degree burns, and skin tears), and draining wounds. The device is intended for one-time use.

## COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

Cytal™ Wound Matrix has the same intended use as predicate device, which is for management of wounds. The technological characteristics of the Cytal" Wound Matrix are substantially similar to the cleared predicate, as both are comprised of animal tissue-derived, collagen extracellular matrix (ECM) scaffolds supplied in a rectangular sheet configuration that are packaged and terminally sterilized. The available sizes of the subject device (25 - 150 cm²) are consistent with the range of sizes of the predicate device (16 - 280 cm²). The subject device and the predicate device both consist of multilaminate sheets ranging from 1-8 layers. The minor difference between the Cytal Wound Matrix and the identified predicate with regard to dehydration method (lyophilized vs. vacuum pressed) does not raise different questions of safety or efficacy and performance testing demonstrates that the device has comparable performance to the predicate.

# PERFORMANCE DATA

#### Biocompatibility Testing

The same material used in the Cytal" Wound Matrix underwent the following biocompatibility testing on sterilized devices per ISO-10993-1 standard: cytotoxicity, sensitization, irritation/intracutaneous reactivity, acute systemic toxicity, pyrogenicity, subacute and subchronic toxicity and implantation, genotoxicity, and LAL endotoxin. The results of these tests provided evidence that the Cytal Wound Matrix meets biocompatibility requirements of the ISO standard.

#### Mechanical Testing

The same material used in the Cytal" Wound Matrix was tested for suture retention strength. The results of the mechanical testing provided evidence that the Cytal"" Wound Matrix provides adequate mechanical strength for its application.

#### CONCLUSION

Based on testing and comparison to the predicate device. Cytal" Wound Matrix does not raise different questions of safety and effectiveness and the results support a determination of substantial equivalence through this 510(k) Premarket Notification.
