Intended Use

Bard Composix® L/P Mesh is indicated for use in the reconstruction of soft tissue deficiencies, such as for the repair of hernias and chest wall defects.

Device Story

Bard Composix® L/P Mesh is a surgical implant for soft tissue reconstruction; consists of bilayer construction: polypropylene mesh layer and expanded polytetrafluoroethylene (ePTFE) layer; layers stitched together with PTFE monofilament in lock stitch formation; peripheral edge heat-sealed. Larger sizes include an Introducer Tool to facilitate rolling and low-profile delivery through trocars; tool consists of handle, stainless steel rod, and T-cap, similar to PrecisionPass™ Delivery Device. Surgeon uses mesh to reinforce tissue; mesh side visually distinguishable from ePTFE side for correct orientation. Device provides structural support for hernia and chest wall defects; benefits include consistent deployment and reduced profile during laparoscopic placement.

Clinical Evidence

Bench testing only. Biocompatibility testing confirms device is non-toxic and non-sensitizing. Laboratory testing demonstrates material and design equivalence to predicate devices.

Technological Characteristics

Bilayer surgical mesh: 0.0048 inch polypropylene monofilament mesh and ePTFE layer. PTFE monofilament thread lock stitch. Peripheral heat seal. Introducer tool: stainless steel rod, handle, T-cap. Non-active, implantable device.

Indications for Use

Indicated for reconstruction of soft tissue deficiencies, including hernia repair and chest wall defects in patients requiring surgical mesh.

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.

#### C. Predicate Device Names:

- Bard Large Pore Soft™ Mesh Pre-Shaped, K052155 (Davol Inc.), FDA cleared . on 10/20/2005;
- Bard Composix® E/X Mesh, K002684 (Davol Inc.), FDA cleared on 10/11/2000; .
- Davol Delivery System (currently marketed as PrecisionPass Laparoscopic . Delivery Device), K041641 (Davol Inc.), FDA cleared on 07/01/2004.

#### D. Device Description:

The Composix® L/P Mesh, will consist of a layer of polypropylene mesh and a layer of expanded polytetrafloroethylene (ePTFE) stitched together using Polytetrafluroethylene (PTFE) monofilament thread sewn in a lock stitch formation. The polypropylene layer is knitted from 0.0048 inch polypropylene monofilament, which is identical to the currently marketed Large Pore Soft™ Mesh. The thickness of the ePTFE layer is identical to the currently marketed Composix® E/X Mesh. As with the currently marketed Composix E/X, the peripheral edge of the polypropylene mesh will be heat sealed to the ePTFE layer.

The layers of the Composix L/P Mesh will be sewn together using rows of interspaced stitching, which will allow the surgeon to tailor the product. Using the stitch pattern as a guide, the surgeon can tailor the product. For user convenience to facilitate the

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

deployment of the larger sized Composix L/P products, the larger sizes of the Composix L/P products will be packaged with an Introducer Tool. This Introducer Tool is similar to the rolling tines/plunger assembly and T-handle of the PrecisionPass™ Delivery Device. The Introducer Tool consists of a handle with a thin stainless steel rod. The stainless steel rod is split into two pieces along its length and has ridges around the perimeter to facilitate use. Similar to the T-handle provided with the PrecisionPass Device, the Introducer Tool's T-cap will be used to secure the open end of the metal rolling tines during the rolling process, then removed prior to delivering the device through the trocar.

#### E. Intended Use:

Bard Composix® L/P Mesh is indicated for use in the reconstruction of soft tissue deficiencies, such as for the repair of hernias and chest wall defects.

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

Bard Composix® L/P Mesh and the Predicate mesh have the same indication: reinforce soft tissue, i.e., repair of hemias and chest wall defects.

The Proposed Product has similar physical attributes, performance characteristics, and materials as the Predicates Bard Composix® E/X and Bard Large Pore Soft™ Mesh. Furthermore, it has similar manufacturing methods as the Predicate Bard Large Pore Soft™ Mesh and Predicate Bard Composix E/X Mesh.

The key differences in the Proposed Product as compared to the Predicate Products, is that the Predicate Bard Large Pore Soft™ Mesh Product is a large pore singlelayer polypropylene monofilament mesh and the Proposed Product is a bilayer construction. While both the Predicate Bard Composix E/X Mesh and the Proposed Product Bard Composix® L/P Mesh are similar in their bilayer construction, the two products combine different types of knitted polypropylene mesh with the same ePTFE layer. The Predicate Bard Composix E/X Mesh utilizes 0.006" Bard Flat Mesh with ePTFE, and the Proposed Product Bard Composix® L/P Mesh uses the 0.0048" Predicate Bard Large Pore Soft™ Mesh with a layer of ePTFE. In addition, the larger sizes of the Proposed Product Bard Composix® L/P Mesh will be packaged with an Introducer Tool. The Bard Composix® L/P Mesh Introducer Tool will facilitate rolling the device with a consistent technique; this will allow a low-profile device to be placed through the appropriate trocar sizes. The mesh side is visually distinguishable from the ePTFE side to determine correct prosthetic orientation. This is standard practice, similar to the other Composix® line products. Furthermore, the Introducer Tool is similar to the tines packaged with the Precision Pass

tool. The Precision Pass tool is packaged separately but often used jointly with the Bard Composix® E/X. The mode of operation, physical attributes, performance characteristics and materials of the Bard Composix® L/P Mesh Introducer Tool packaged with the larger sizes of the are all similar to the Davo! Delivery System (Precision Pass tool).

#### ું. Performance Data

Biocompatibility and bench testing provided in this submission support the safety and effectiveness of Bard Composix® L/P Mesh for its intended use. The biocompatibility testing completed on the product manufactured with the same materials and similar processes as the Bard Composix L/P Mesh demonstrate the device is non-toxic and non-sensitizing to biological tissues consistent with its intended use. Laboratory testing discussed in this submission demonstrate that the material chosen and the design utilized in manufacturing Bard Composix® L/P Mesh is substantially equivalent to the referenced Predicate Products.
