Intended Use

Prolene Soft Polypropylene Mesh may be used for the repair of hernia or other fascial defects that require the addition of a reinforcing or bridging material to obtain the desired surgical result.

Device Story

Prolene Soft Polypropylene Mesh is a sterile, nonabsorbable synthetic surgical mesh; composed of knitted filaments of extruded polypropylene with blue monofilament contrast striping. Device is used by surgeons in clinical settings for hernia or fascial defect repair. Mesh is cut to desired shape/size by surgeon to provide reinforcement or bridging at defect site. Bi-directional elastic construction allows adaptation to body stresses; prevents unraveling when cut. Device provides permanent tissue support. Benefits include reinforcement of weakened tissue to facilitate surgical repair.

Clinical Evidence

Bench testing only. Evaluated physical characteristics (knitting pattern, pore size, density, thickness, stiffness) and performance (burst strength, suture pullout strength) per FDA guidance. Biocompatibility tested per ISO 10993-1:2009. Sterility validated per ISO 11737-1 and ISO 10993-7:2008; SAL 10^-6 achieved.

Technological Characteristics

Knitted extruded polypropylene monofilament mesh; 3.5 mil fiber diameter. Macro-porous, non-absorbable. Bi-directional elasticity. Sterilized via Ethylene Oxide (EO). Materials meet ISO 10993-1:2009. Dimensions: 50 cm x 50 cm.

Indications for Use

Indicated for patients requiring hernia or fascial defect repair needing reinforcing or bridging material.

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

PROLENE Soft Mesh is a sterile, nonabsorbable synthetic surgical mesh designed for the repair of hernias and other fascial defects. The implant device is composed of knitted filaments of extruded polypropylene. Blue PROLENE™ monofilaments have been integrated to produce contrast striping in the mesh.

PROLENE Soft Mesh is constructed of knitted filaments of extruded polypropylene identical in composition to that used in PROLENE Polypropylene Suture, Nonabsorbable Surgical Sutures, U.S.P. (ETHICON, INC.). Blue PROLENE monofilaments have been incorporated to produce contrast striping in the mesh. The mesh is constructed of 3.5 mil diameter monofilament fibers, knitted into a unique design that results in a mesh that is approximately 50 percent more flexible than standard PROLENE Mesh. Polypropylene material, when used as a suture, has been reported to be non-reactive and to retain its strength indefinitely in clinical use.

PROLENE Soft Mesh is knitted by a process which interlinks each fiber junction and which provides for elasticity in both directions. This construction permits the mesh to be cut into any desired shape or size without unraveling. The bi-directional elastic property is designed to allow adaption to various stresses encountered in the body.

## Indications for Use

The PROLENE Soft Polypropylene Mesh may be used for the repair of hernia or other fascial defects that require the addition of a reinforcing or bridging material to obtain the desired surgical result. The Indications for Use on the Prolene Soft Mesh 50 cm x 50 cm subject device is identical to the predicate device.

### Summary of Technological Characteristics

The predicate and subject devices function in the same manner. They are designed as prosthetic material for the repair of hernias and other fascial deficiencies by providing reinforcement or acting as bridging materials. The technological characteristics of the subject device are different as compared to the predicate device. Both predicate and subject PROLENE Soft Mesh devices are composed of a macro porous non-absorbable synthetic surgical mesh. The additional size (50 cm x 50 cm) of the subject device has been developed to satisfy customer needs.

The safety and effectiveness and substantial equivalence of the predicate device and subject device has been demonstrated via data collected during design validation and design verification. The results of these tests provide reasonable assurance that the subject device has been designed and tested to assure conformance to the requirements for its intended use. No new safety or performance issues were raised during the testing. All materials used in the proposed device are the same as the predicate device and meet the requirements of ISO 10993-1:2009 Biological evaluation of medical devices - Part 1: Evaluation and Testing within a risk management process.

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

#### Performance Data

The following performance data were provided in support of the substantial equivalence determination:

- Biocompatibility PROLENE Soft Mesh is a permanent (>30 days) implant device 1. contacting tissue. The biocompatibility for PROLENE Soft Mesh 50 cm x 50 cm has been evaluated in accordance with ISO 10993-1:2009 "Biological Evaluation of Medical Devices - Evaluation and Testing", and ANSI/AAMI ST72:2011 "Bacterial endotoxins -Test methods, routine monitoring, and alternatives to batch testing." Endotoxin testing was performed in accordance with ANSI/AAMI ST72:2011 and met criteria of < 20 EU average/device.
- 2. Sterility EO/ECH residual testing in accordance with ISO 10993-7:2008 was completed to verify that acceptable EO and ECH limits can be achieved for the subject device after exposure to the validated sterilization cycles. In conclusion, the subject device has a relatively low affinity for EO/ECH sterilization residues. Natural Product Resistance Testing (NPRT) and Comparative Resistance Testing was performed and results confirmed the subject device had met acceptance criteria. Bioburden testing, in accordance with ISO 11737-1, confirmed that the subject device had met the defined acceptance criteria. Overall, the sterility validation demonstrated that subject PROLENE Soft Mesh (50 cm x 50 cm) achieves a sterility assurance level of 10-9.
- 3. Bench Testing Bench top testing was performed to assess the physical/performance characteristics of the new device. In accordance with FDA's "Guidance for the Preparation of a Premarket Notification Application for a Surgical Mesh" (March 2, 1999). the bench top testing evaluated physical characteristics of mesh including mesh knitting pattern, mesh pore size/porosity, mesh density, mesh thickness, and mesh stiffness as well as mesh performance testing including mesh burst strength and suture pullout strength.

### Summary of Substantial Equivalence Comparison

The subject device, PROLENE Soft Mesh 50 cm, is equivalent to the predicate PROLENE Soft Mesh described in 510(k) K001122 with the exception of the size of the mesh patch. In accordance with Appendix A, 510(k) Decision Making flow chart from FDA's guidance "The 510(k) Program: Evaluating Substantial Equivalence in Premarket Notifications [510(k)]", the predicate device is legally marketed, the labeling is consistent with the IFU statements, the devices (predicate and subject) have the same intended use. The larger size is a new technological characteristic, however, it does not raise questions of safety and effectiveness.

The subject device and the predicate device share:

- the same operating principle,
- . the same intended use,
- . the same materials.
- the same packaging materials, ●
- the same labeling components,
- the same sterilization process (Ethylene Oxide),

{6}------------------------------------------------

- the same sterility assurance level (SAL) is 10-6 and ●
- . the same shelf life

In summary, the proposed device, PROLENE Soft Mesh 50 cm x 50 cm, is substantially equivalent to the predicate device.

#### Conclusions

Clinical literature evidence and performance data support that the device is as safe and as effective as the predicate device for the intended use. Thus we conclude that the proposed device is substantially equivalent to the predicate device under the Federal Food, Drug, and Cosmetic Act
