# Device Description

Excellagen is a wound care device composed of formulated, 2.6% (26 mg/mL) fibrillar bovine dermal collagen (Type I) that is topically applied directly to the wound surface. Excellagen is packaged as single-use units to ensure safety and provide for easy topical application. The device is tested for sterility in accordance with USP<71>. Excellagen is supplied in one of two kit configurations. One kit configuration consists of four single-use 1.0 cc syringes, each containing 0.5 cc of 2.6% (26 mg/mL) formulated collagen, and four singleuse sterile flexible applicators. This kit can be used for smaller wounds. The

second kit configuration consists of one single-use 10.0 cc syringe containing 4.0 cc of 2.6% (26 mg/mL) formulated collagen, and one single-use sterile flexible applicator. This kit can be used for larger or tunneling/undermined wounds. Excellagen is stored at standard refrigeration temperature (2-8°C).

During manufacture, the collagen component of Excellagen is purified using a specialized process that eliminates impurities (including endotoxins), and removes denatured molecules and collagen fragments. Excellagen consists almost exclusively of high molecular weight, intact, fibrillar collagen and is formulated at a concentration of 2.6% (26 mg/mL) in an isotonic buffer with protein stabilizing agents.

#### Intended Use

Excellagen is a wound care device intended for the management of wounds including partial and full thickness wounds, pressure ulcers, venous ulcers, diabetic ulcers, chronic vascular ulcers, tunneled/undermined wounds, surgical wounds (donor sites/grafts, post-Moh's surgery, post-laser surgery, podiatric, wound dehiscence), trauma wounds (abrasions, lacerations, second-degree burns, and skin tears) and draining wounds. This device is packaged for onetime use.

Excellagen is contraindicated for individuals with a known sensitivity to products of bovine origin.

# Technological Characteristics Compared to Predicates

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

#### Safety

The safety of Excellagen has been established based on standard non-clinical in vitro (cytotoxicity) and in vivo (sensitization and intracutaneous reactivity) biocompatibility testing in accordance with ISO 10993-1. Excellagen was found to be biocompatible in all tests.

#### Substantial Equivalence

Excellagen is substantially equivalent in function (wound management), materials (bovine Type I collagen), intended use (direct topical application to dermal wounds) and safety profile (biodecradable and biocompatible, passed sterility testing in accordance with USP<71>) to the following products which have been cleared to market under Section 510(k) premarket notifications: Integra Flowable Wound Matrix (K072113), Stimulen Collagen (K030774) Medifil gel (K910944), HyCure Hydrolyzed Collagen (K955506), Collatek Powder (K012990), HeliDerm Collagen Wound Dressing (K990086).

#### Conclusion

Excellagen is safe under the proposed conditions of use and substantially equivalent to its predicate devices.

The text is small and difficult to read, but it appears to be the name of an organization or agency. The symbol in the center consists of three curved lines that resemble a bird in flight or a stylized representation of water waves.
