Intended Use

The proposed device is indicated to reinforce soft tissue where weakness exists, i.e., repair of hernias and chest wall defects.

Device Story

Bard Soft Mesh is a sterile, single-use surgical mesh for reinforcing soft tissue during hernia and chest wall defect repairs. Constructed from polypropylene monofilament (approx. 0.004 inch diameter), the mesh features a specific knit pattern providing bi-directional flexibility, a thin profile, and reduced material volume compared to traditional polypropylene meshes. Available in various rectangular sheets and pre-shaped forms, it is intended for use by surgeons in clinical settings. The device provides mechanical support to weakened tissue, facilitating repair. Unused mesh may be resterilized per instructions.

Clinical Evidence

Bench testing only. Biocompatibility testing confirmed the material is non-toxic and non-sensitizing. Laboratory testing verified that the design and material meet established specifications for consistent performance.

Technological Characteristics

Polypropylene monofilament surgical mesh; 0.004-inch filament diameter; knitted construction for bi-directional flexibility; sterile, single-use; available in rectangular sheets and pre-shaped forms.

Indications for Use

Indicated for reinforcement of soft tissue where weakness exists, specifically for the repair of hernias and chest wall defects in patients requiring surgical intervention.

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

### D. Device Description

The proposed Bard Soft Mesh is a single layer of mesh constructed from polypropylene monofilament with a diameter of approximately 0.004 inches. The mesh is knitted to form a strong, porous, support material. The small diameter of the polypropylene monofilament allows for a thin profile and creates a mesh with increased flexibility and a reduced amount of material compared to traditional monofilament polypropylenc meshes. The proposed device is manufactured utilizing a strong knit design that allows for bi-directional flexibility and tailoring in any direction. The proposed device will be marketed as a stcrile, single use device and will be available in several sizes of rectangular sheets and pre-shaped forms. The option to restcrilize unused mesh has been provided in the instructions for use.

#### Intended Use E.

The proposed device is indicated to reinforce soft tissue where weakness exists, i.e., repair of hemias and chest wall defects.

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

Bard Soft Mesh and the predicate Bard Mesh have an identical intended use. Both devices are indicated to reinforce soft tissue where weakness exists, i.c., repair of hernias and chest wall defects.

The proposed device has similar physical attributes and performance characteristics as the predicates Bard Mesh, ProLite Ultra and Mersilene Mesh. Furthermore, it has the same materials and similar manufacturing methods as the predicate Bard Mesh.

The key differences in the proposed device compared to the predicate devices is in the diameter of the polypropylene monofilaments and the knit pattern of the mesh. In order to create a thinner, lighter weight mesh while also reducing the amount of material used in the mesh compared to traditional monofilament polypropylene meshes, the proposed device was constructed from monofilaments with a diameter of approximately 0.004 inches similar to the prodicate ProLite Ultra. The knit pattern of the mesh was designed in order to create a mesh with a soft feel and to allow for a more even stretch in both directions of the prosthesis.

#### Performance Data ੁੱ

Biocompatibility and bench testing have been completed and support the safety and effectiveness of Bard Soft Mesh for its intended use.

The biocompatibility test results show that the material used in the design and manufacture of the device is non-toxic and non-sensitizing to biological tissues consistent with its intended use. Laboratory test results demonstrate that the material chosen and the design utilized in manufacturing Bard Soft Mesh will meet the established specifications necessary for consistent performance during its intended use.
