#### INDICATIONS FOR USE

Gentrix™ Surgical Matrix 2-layer and 3-layer are intended for implantation to reinforce soft tissue where weakness exists in patients requiring urological, gastroenterological, or plastic & reconstructive surgery. Reinforcement of soft tissue within urological, gastroenterological, and plastic & reconstructive surgery includes, but is not limited to, the following procedures; hernia and body wall repair, colon and rectal prolapse repair, and esophageal repair.

Gentrix™ Surgical Matrix 6-layer and 8-Laver are intended for implantation to reinforce soft tissue where weakness exists in - patients requiring - gastroenterological or plastic & reconstructive surgery. Reinforcement of soft tissue within gastroenterological and plastic & reconstructive surgery includes, but is not limited to, the following procedures: hernia and body wall repair, colon and rectal prolapse repair, tissue repair, and esophageal repair.

#### EQUIVALENCE TO MARKETED DEVICES

Gentrix™ Surgical Matrix 2-Layer, 3-Layer, 6-Layer have the same intended use as the predicate and reference surgical meshes, which is to reinforce soft tissue where weakness exists. The technological characteristics of the Gentrix™ Surgical Matrix 2-Layer, 6-Laver, and 8-Laver are substantially similar to the cleared predicate and reference devices, as all are identical in materials and manufacturing to the predicate and reference devices. Gentrix™ Surgical Matrix, the predicate device, and the reference device are comprised of animal tissue-derived, collagen extracellular matrix (ECM) scaffolds supplied in a multilaminate rectangular sheet configuration that are packaged and terminally sterilized. The available sizes of the subject device (8 – 150 cm²) are identical with the range of sizes of the predicate device, and within the range of the cleared reference device (8 – 280 cm²). The packaging system for Gentrix™ Surgical Matrix 2-Layer, 3-Layer, 8-Layer was validated per ANSI/AAMI/ISO 11607-1 and -2. and is substantially similar to the packaging system used for the cleared predicate and reference devices. The minor differences between the Gentrix™ Surgical Matrix 2-Layer, 3-Layer, 6-Layer and the predicate and reference devices do not raise different questions of safety or efficacy and performance testing demonstrates that the device has comparable performance to the predicates.

#### PERFORMANCE DATA

#### Biocompatibility Testing

Gentrix™ Surgical Matrix 2-Layer, 3-Layer, 8-Layer underwent the following biocompatibility testing on sterilized devices per FDA's extent of recognition of ISO-10993-1 standard for a permanently implanted device: cytotoxicity, sensitization, irritation/intracutaneous reactivity, acute systemic toxicity, pyrogenicity, subacute and subchronic toxicity and implantation, genotoxicity, hemocompatibility, and LAL endotoxin. The results of these tests provided evidence that the Gentrix™ Surgical Matrix is substantially equivalent to the predicate and reference devices and meets biocompatibility requirements of the ISO standard.

{5}------------------------------------------------

#### Mechanical Testinq

Gentrix™ Surgical Matrix 2-Layer, 6-Layer, 8-Layer material was tested for the following: tensile strength, suture retention strength, ball burst strength, delamination strength, tear strength, and stiffness test. The results of the mechanical testing provided evidence that the Gentrix™ Surgical Matrix is substantially equivalent to the predicate and reference devices and provides adequate mechanical strength for its application throughout its labeled shelf life.

#### Material Characterization

Gentrix™ Surgical Matrix 2-Layer, 3-Layer, 8-Layer material was tested for the following: moisture content, hydration uptake, and hydrated onset temperature. The results of the material characterization testing provided evidence that the Gentrix is substantially equivalent to the predicate and reference devices and provides adequate performance for its application throughout its labeled shelf life

### CONCLUSION

Based on direct testing and comparison to predicate and reference devices, Gentrix™ Surgical Matrix 2-Layer, 3-Layer, 6-Layer do not raise different questions of safety and effectiveness and the results support a determination of substantial equivalence through this 510(k) Premarket Notification.
