Intended Use

The proposed device, Ventrio ST Hernia Patch, is a sterile, single use device indicated for use in the reconstruction of soft tissue deficiencies, where weakness exists, in procedures involving soft tissue repair, such as for the repair of hernias. The intended use for the proposed device. Ventrio ST Hernia Patch, is the same as the predicate devices. Ventrio Hernia Patch and Sepramesh IP Mesh.

Device Story

Ventrio ST Hernia Patch is a sterile, single-use, self-expanding, partially absorbable surgical prosthesis for soft tissue/hernia repair. Device consists of two layers stitched with PTFE monofilament: a top layer of knitted polypropylene mesh and a bottom layer of Sepramesh IP Mesh (co-knitted polypropylene and polyglycolic acid fibers). The visceral side features a bioresorbable hydrogel coating (sodium hyaluronate, carboxymethylcellulose, polyethylene glycol) to minimize tissue attachment; coating resorbs in <30 days. Sorbaflex Memory Technology, using an extruded polydioxanone (PDO) monofilament ring, provides stability for insertion and placement; PDO degrades via hydrolysis in 6-8 months. Used by surgeons in clinical settings. The fascial side promotes fibroblastic response and tissue ingrowth. Device facilitates surgical repair of soft tissue deficiencies.

Clinical Evidence

Bench testing and preclinical studies performed. Bench testing evaluated physical properties (weave, pore size, density, thickness, stiffness) and mechanical performance (burst strength, suture pullout, weld tensile strength, dry bond strength). Preclinical pig study evaluated peritoneal attachment, mesh contracture, tissue ingrowth, and inflammatory response. In vivo rat study evaluated degradation of coating, PGA fibers, and PDO monofilament. Biocompatibility testing conducted per ISO 10993. No human clinical trial data presented.

Technological Characteristics

Materials: Polypropylene, polyglycolic acid (PGA), polydioxanone (PDO), PTFE, sodium hyaluronate, carboxymethylcellulose, polyethylene glycol. Sensing/Actuation: Mechanical (Sorbaflex PDO ring for shape memory). Dimensions: Patch form factor. Connectivity: None. Sterilization: Sterile. Software: None.

Indications for Use

Indicated for reinforcement of soft tissue where weakness exists, including hernia repair. For prescription use only.

Regulatory Classification

Identification

Surgical mesh is a metallic or polymeric screen intended to be implanted to reinforce soft tissue or bone where weakness exists. Examples of surgical mesh are metallic and polymeric mesh for hernia repair, and acetabular and cement restrictor mesh used during orthopedic surgery.

#### Device Description D.

The proposed device, Ventrio 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. 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

{1}------------------------------------------------

bioresorbable coating, separating 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.

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) monofilament that is contained within a knitted polypropylene mesh tube. The extra large oval size patches contain two separate Sorbaflex PDO monofilaments. The Sorbaflex PDO monofilament fully degrades in vivo by means of hydrolysis. Absorption is essentially complete in 6-8 months.

#### E. Intended Use

The proposed device, Ventrio ST Hernia Patch, is a sterile, single use device indicated for use in the reconstruction of soft tissue deficiencies, where weakness exists, in procedures involving soft tissue repair, such as for the repair of hernias. The intended use for the proposed device. Ventrio ST Hernia Patch, is the same as the predicate devices. Ventrio Hernia Patch and Sepramesh IP Mesh.

### F. Summary of Similarities and Differences in Technological Characteristics, Performance and Intended Use

The proposed device, Ventrio ST Hernia Patch, has the same design as the currently marketed Ventrio Hernia Patch (K100229) with the exception of the posterior polypropylene mesh laver and the single layer of expanded polytetrafluoroethylene (ePTFE). These two layers have been replaced by Sepramesh IP Mesh which is a coknitted polypropylene/PGA mesh with a bioresorbable coating. The anterior polypropylene slit mesh and PDO monofilament ring contained within a knitted tube mesh are the same as the predicate device, Ventrio Hernia Patch, as well as the interlocking stitch using polytetrafluoroethylene (PTFE) monofilament to sew the patch. The Sepramesh IP Mesh

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

used in the proposed device is exactly the same as the currently marketed device, Sepramesh IP Mesh.

Laboratory bench testing was performed to verify that the proposed device's performance characteristics are similar to that of the predicate devices.

#### G. Performance Data

Bench testing was performed to assess the effects of the new characteristics of the proposed device, Ventrio ST Hernia Patch. The tests compared the proposed device against the predicate devices, 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, PDO ring weld tensile strength, PGA pullout strength, dry bond strength, mass/area measurements, and deployment/hydrogel disruption testing. In addition, two preclinical studies were performed. An overall performance study in pigs was 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, Ventrio 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.

{3}------------------------------------------------

The results demonstrate that the proposed device is substantially equivalent to the currently marketed predicate devices and therefore, the proposed device, Ventrio ST Hernia Patch, is safe and effective for its intended use.
