(please refer to product pamphiet )

Device Story

Herniamesh surgical meshes are polypropylene monofilament implants used for hernia repair and chest wall defect reconstruction. Devices include flat mesh designs (Hertra 1, 2, 2A; Hermesh 3, 4, 5) and three-dimensional plugs (T1, T2, T3). Used by surgeons in clinical settings to reinforce weak fascial structures or prevent lung herniation when autogenous tissue is insufficient. The mesh provides a scaffold for tissue ingrowth. The device is implanted during surgical procedures; it does not involve external data processing or software.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Polypropylene monofilament; knitted mesh design; flat or three-dimensional form factors; non-absorbable; sterile.

Indications for Use

Indicated for surgical repair of abdominal wall hernias (primary or recurrent inguinal, femoral, incisional) and thoracic wall defects.

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.

Predicate Devices

• Trelex Mesh (Meadox Medicals)
• Marlex Mesh (Bard Vascular Systems Division, C.R. Bard, Inc.)
• Marlex Mesh Dart (Bard Vascular Systems Division, C.R. Bard, Inc.)

# PREMARKET NOTIFICATION FOR HERNIAMESH PRODUCTS

### MAY 11 1998

#### SUMMARY OF SAFETY AND EFFECTIVENESS

The Herniamesh surgical meshes are substantially equivalent to Trelex mesh currently marketed by Meadox Medicals, and to Marlex Mesh and the Marlex Mesh Dart currently marketed by Bard Vascular Systems Division, C.R. Bard, Inc. Trelex Mesh and Marlex mesh are both available in a variety of shapes and sizes. The "510 (k) "substantial Equivalence" Decision-Making Process (Detailed)" decision tree was utilized to make a determination of substantial equivalence (see Exhibit I). The answers to the following four questions lead to a determination of substantial equivalence.

#### 1. Does New Device Have Same Indication Statement?

Yes, all of the indications for Herniamesh products are identical to those of the predicate devices. All are indicated for the repair of abdominal wall hernias, femoral hernias or chest wall defects.

## 2. New Device Has Same Intended Use and May be "Substantially Equivalent"?

Yes, the intended use of Herniamesh products are the same as predicate devices.

Herniamesh products Hertra 1. 2 & 2A and Hermesh 3, 4 & 5 have the same intended uses as Trelex Mesh and Marlex Mesh. All are used in the repair of primary or recurrent inguinal hernias (particularly when facial structures are weak), primary or recurrent inscisional hernias so large that the fascial edges of the hernial ring cannot be approximated (generally one-fourth of the abdominal wall), femoral hernias, or chest wall defects where it is not possible to use autogenous tissue to prevent or correct lung herniation.

Herniamesh Plugs T1, T2 & T3 have the same intended use as the Marlex Mesh Dart which is used for the repair of hernias with a three dimensional shape i.e. femoral, inguinocrueal or large recurrent inguinal hernias.

#### 3. Does New Device Have Same Technological Characteristics, e.g., Design, Materials, etc.?

Yes, Herniamesh products have the same technological characteristics as predicate devices. Herniamesh products, Trelex mesh, Marlex Mesh and the Marlex Mesh Dart are all made of the same material. All are a polypropylene monofilament of various thickness.

The design and structureof Herniamesh products Hertra 1, 2, & 2A, Hermesh 3, 4 & 5 and Plug T1 are the same as Trelex Mesh and Marlex Mesh. All are a monofilament knitted into a mesh design and flat in structure.

The design and srtucture of Herniamesh Plugs T2 and T3 are the Marlex Mesh Datt. All are a monofilament knitted into a mesh design and three-dimensional in structure with the same indications for use. The major differences between all of these products are the thickness of the monofilament and the type of knit used to achieve the mesh design.

### 4. Are The Descriptive Characteristics Precise Enough to Ensure Equivalence?

Yes, since Herniamesh products are constructed of the same materials, have the same design and the same structure as predicate devices then the descriptive characteristics that apply to Trelex Mesh, Marlex Mesh and the Marlex Mesh Dart also apply to Herniamesh products. The process validation will demonstrate that these properties are maintained.

#### "Substantially Equivalent" Determination

Based on the above answers the surgical meshes produced by Herniamesh are substantially equivalent to the predicate devices, Trelex Mesh, Marlex Mesh and the Marlex Mesh Dart.
