# Device Description

The Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend devices are composed of porcine-derived extracellular matrix scaffolds, specifically known as urinary bladder matrix. The devices are supplied in an eight-layer sheet configuration in sizes up to 30 cm x 40 cm, and packaged in double peel-open pouches. The devices are terminally sterilized using electron beam irradiation. The implantable biomaterial is a resorbable extracellular matrix scaffold that will incorporate (remodel) into the body through cellular infiltration, capillary growth, and integration by the surrounding host tissue. Animal studies have shown device resorption in approximately 240 days.

#### Intended Use / Indications for Use

Gentrix Surgical Matrix Thick and Gentrix Surgical Matrix Extend 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.

# Performance Data

#### Bench - Biocompatibility Testing

The subject devices were evaluated for biocompatibility per ISO-10993 including the following: cytotoxicity, sensitization, irritation/intracutaneous reactivity, acute systemic toxicity, subacute and subchronic toxicity and implantation, genotoxicity, hemocompatibility, and LAL endotoxin. The evaluation demonstrates that the subject devices meet the biocompatibility requirements of the ISO standard.

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

#### Bench - Mechanical Testing

Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend configurations were tested for the following: tensile strength, suture retention strength, and tear strength, and tear strength. The results of the mechanical testing provided evidence that the subject devices are substantially equivalent to the predicate device, and provide adequate mechanical strength for its application throughout its labeled shelf life.

# Bench - Material Characterization

Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend configurations were tested for the following: stiffness, moisture content, hydration uptake, and hydrated onset temperature. The results of the material characterization testing provided evidence that the subject devices are substantially equivalent to the predicate device and provide adequate performance for its application throughout its labeled shelf life.

# Animal Testing

Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend configurations were evaluated in a pre-clinical porcine model of incisional ventral hernia repair through full device degradation and remodeling. These animal studies provide evidence of full host tissue integration and demonstrate substantially equivalent performance between the subject and predicate devices. In addition, these results support the biocompatibility of the subject devices.

# Clinical

No Clinical data was provided in support of this clearance.

# Conclusions

The Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend are as safe and effective as the Gentrix™ Surgical Matrix 8-Layer. The Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend have identical intended uses, indications, and principles of operation; additionally the subject and predicate devices have identical or similar technological characteristics. The minor technological differences between the Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend and the predicate device raise no new issues of safety or effectiveness. Performance data demonstrate that the Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend are as safe and effective as the Gentrix™ Surgical Matrix 8-Layer. Thus, the Gentrix™ Surgical Matrix Thick and Gentrix™ Surgical Matrix Extend are substantially equivalent to the predicate device.
