No
The device description and performance studies focus on the material properties and mechanical performance of a hernia patch, with no mention of AI or ML.
Yes
The device aids in the reinforcement of soft tissue and repair of hernias, which directly addresses a weakness or condition in the body for therapeutic benefit.
No
Explanation: The Ventralex ST Hernia Patch is described as a "self-expanding bioresorbable coated, partially absorbable, sterile prosthesis" used for "reinforcement of soft tissue" and "repair of hernias." Its function is to physically support and repair tissue, not to diagnose a condition.
No
The device description clearly details a physical hernia patch made of various materials (polypropylene mesh, PGA fibers, bioresorbable coating, PDO monofilament) and includes information about its physical characteristics and performance in bench and preclinical studies. There is no mention of software as a component or the primary function of the device.
Based on the provided information, the Ventralex ST Hernia Patch is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is "in the reinforcement of soft tissue, where weakness exists, in procedures involving soft tissue repair, including repair of hernias and deficiencies caused by trocars." This describes a surgical implant used in vivo (within the body) to physically support tissue.
- Device Description: The description details a physical prosthesis made of various materials (polypropylene, PGA, PDO, hydrogel coating) designed to be implanted.
- Lack of IVD Characteristics: The description does not mention any components or functions related to testing samples in vitro (outside the body) to diagnose diseases or conditions. There is no mention of reagents, calibrators, controls, or analytical procedures performed on biological specimens.
In summary, the Ventralex ST Hernia Patch is a surgical implant, not an IVD.

Intended Use / Indications for Use

Device Description
The proposed device. Ventralex ST Hernia Patch, is a self-expanding bioresorbable coated, partially absorbable, sterile prosthesis, containing 2 distinct layers stitched with PTFE monofilament, forming a positioning pocket and strap. The top layer is knitted polypropylene mesh, 0.004" in monofilament diameter, and the bottom layer is Sepramesh IP Mesh. Sepramesh IP Mesh is co-knitted using polypropylene (PP) and polyglycolic acid (PGA) fibers to result in a two-sided mesh with a PP surface and a PGA surface. The mesh is coated on the PGA surface with a bioresorbable, chemically modified sodium hyaluronate (HA), carboxymethylcellulose (CMC) and polyethylene glycol (PEG) based hydrogel. The fascial side of the mesh allows a prompt fibroblastic response through the interstices of the mesh, allowing for tissue ingrowth into the mesh. The visceral side of the mesh is a bioresorbable coating the mesh from underlying tissue and organ surfaces to minimize tissue attachment to the mesh. Shortly after placement, the biopolymer coating becomes a hydrated gel that is resorbed from the site in less than 30 days.
A depth marker on the positioning strap for the small Ventralex ST Hernia Patch is designed to facilitate placement of the small patch through a trocar.
The device contains Sorbaflex Memory Technology which provides memory and stability to the device, facilitating ease of initial insertion, proper placement, and fixation of the device. The Sorbaflex Memory Technology is comprised of an extruded polydioxanone (PDO) absorbable monofilament that is contained within a knitted polypropylene mesh tube. The Sorbaflex PDO monofilament fully degrades in vivo by means of hydrolysis. Absorption is essentially complete in 6-8 months.

Summary of Performance Studies
Bench testing was performed to assess the effects of the new characteristics of the proposed device, Ventralex ST Hernia Patch. The tests compared the proposed device against the predicate devices, Ventralex Hernia Patch, Ventrio Hernia Patch, and Sepramesh IP Mesh. In accordance with FDA's "Guidance for the Preparation of a Premarket Notification Application for a Surgical Mesh" (March 2, 1999), the tests included physical characteristics including mesh weave, mesh pore size, device density, device thickness, device stiffness as well as performance evaluations including burst strength, suture pullout strength, strap strength, PDO ring weld tensile strength, PGA pullout strength, dry bond strength, mass/area measurements, and deployment/hydrogel disruption testing. In addition, preclinical studies were performed. Overall performance studies in pigs were performed to evaluate peritoneal tissue attachment, percent area coverage, mesh contracture, tissue ingrowth, and host inflammatory/fibrotic response. An in vivo degradation study was performed in rats to evaluate the host inflammatory/fibrotic response and absorption characteristics of the bioresorbable coating, PGA fibers, and the PDO monofilament during degradation of the material in vivo. The testing presented in this submission demonstrates that the proposed device, Ventralex ST Hernia Patch, is substantially equivalent to the predicate devices. The results of the testing can be found in Section 16.
Biocompatibility testing in accordance with the ISO 10993 standards was conducted. The results indicate that the device is biocompatible per these standards. Results are summarized in Section 15 and copies of the test reports are in Attachment 3.
The results demonstrate that the proposed device is substantially equivalent to the currently marketed predicate devices and therefore, the proposed device, Ventralex ST Hernia Patch, is safe and effective for its intended use.
