No.
The device is described as a surgical graft intended for implantation to reinforce and repair soft tissue. While it aids in the body's repair process, its primary function is structural reinforcement and not directly treating a disease or therapeutic condition. The antimicrobial coating is to protect the device itself from colonization, not to therapeutically treat the patient.
No
The device is described as a surgical graft intended for implantation to reinforce and repair soft tissue, not to diagnose medical conditions.
No
The device is a physical surgical graft made from porcine dermal matrix with an antimicrobial coating. It is intended for implantation and tissue reinforcement, not a software application.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for implantation to reinforce and repair soft tissue. This is a surgical device used in vivo (within the body).
- Device Description: The description details a surgical graft made from porcine dermal matrix, designed for implantation.
- Lack of IVD Characteristics: There is no mention of the device being used to test samples in vitro (outside the body) to diagnose a condition, monitor treatment, or screen for diseases. IVDs typically involve analyzing biological samples like blood, urine, or tissue.
The device is a surgical implant with an antimicrobial coating, intended for direct use in surgical procedures on patients.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The XenMatrix™ AB surgical mesh was evaluated in the following assessments:
- Biocompatibility testing: Biocompatibility testing in accordance to the current ISO 10993 series was conducted on the finished device and the results indicate that the device is biocompatible per these standards.
- Bench testing: Bench testing in accordance with the FDA Guidance for the Preperation of a Premarket Notification Application for a Surgical Mesh was conducted comparing the XenMatrix™ AB device with the cited predicates. The testing included:
a. Physical Characteristics:
i. Device Thickness
ii. Device (Flexural) Stiffness
b. Functional Characteristics:
i. Burst Strength
ii. Suture Pullout Strength
iii. Tear Resistance
Results demonstrate that the physical and functional characteristics of XenMatrix™ AB Surgical Mesh are substantially equivalent to the predicate comparator devices. - In vivo strength determinations: The device was implanted in a 28 day, porcine evaluation and tested for strength characteristics in comparison to the cited predicate device at Time zero (To) and Day 28 (D28). This study assessed the following characteristics of the implanted mesh:
a. Mechanical Testing
i. Tensile Testing
ii. Tissue in-growth Testing
iii. Device Burst Testing
b. Percent Area Contracture
c. Peritoneal Tissue Attachments
d. Histology
Results demonstrate that the in vivo performance of XenMatrix™ AB Surgical Mesh is substantially equivalent to the predicate device. - Drug Content and Impurities of the Antimicrobial Agents Rifampin and Minocycline: Analytical and in vitro testing was also performed on the device and included speed to kill, kinetic drug release (KDR), drug content and impurity, and polymer degradation testing. The test results demonstrated substantial equivalence to the predicate comparator surgical mesh with respect to these parameters.
- Animal Testing: An in vivo porcine implantation study was performed to investigate the device's mechanical strength and the host inflammatory response to the device over a 28 day duration. At 28 days, the XenMatrix™ AB surgical mesh had greater tissueingrowth/T-Peel Force values than the surgical mesh predicate. The mechanical strength values (i.e., Ultimate Load/Burst Force, Peak Tensile Strength) of the graft alone were lower than the surgical mesh predicate.
In addition, two in vivo dorsum-implanted rabbit infection model studies were performed. Devices were inoculated with bacteria at implantation, and at 7 days, post-implantation, bacterial colonization quantifications were conducted. At that time point the antimicrobial coating on the XenMatrix™ AB was observed to prevent bacterial colonization of the device in comparison to the surgical mesh predicate device. The relevance of these studies to human clinical performance outcomes has not been demonstrated. The correlation of these studies has not been demonstrated to be predictive of positive human clinical outcomes. - Human clinical data: None. The claim of reduction of colonization has not been established with human clinical data, nor has a clinical impact associated with this claim been demonstrated.
