Indications for Use

The GORE BIOABSORBABLE MESH is intended for use in the reinforcement of soft tissue. Examples of applications where the GORE BIOABSORBABLE MESH may be used include, but are not limited to: Hernia repair (inguinal, femoral, umbilical, abdominal, diaphragmatic, incisional, epigastric, gastroesophageal, hiatal, intermuscular). Muscle flap reinforcement Perforated tissue repair General tissue reconstruction's (periosteum, thoracic wall, reinforcement of the bladder wall, suture line reinforcement, tissue deficit, etc.)

Device Story

GORE BIOABSORBABLE MESH is a synthetic, microporous, bioabsorbable scaffold used to reinforce soft tissue and bridge defects. Composed of PGA:TMC copolymer fiber; device acts as a temporary bridge, stimulating native tissue ingrowth while gradually absorbing. Available in sheets and preformed 3D shapes; provided sterile for single use. Intended for surgical application by clinicians; requires an overlay patch for high-strength repairs like groin hernias. Benefits include defect filling and tissue reconstruction support during wound healing.

Clinical Evidence

Bench testing only. Device integrity testing was performed to demonstrate that the mesh meets specified requirements and is equivalent to predicate devices. No clinical data provided.

Technological Characteristics

Microporous structure; material: synthetic bioabsorbable poly (67% glycolide: 33% trimethylene carbonate) (PGA:TMC) copolymer fiber. Form factor: sheets and preformed 3D shapes. Sterilization: sterile, single-use.

Indications for Use

Indicated for reinforcement of soft tissue in patients requiring hernia repair (inguinal, femoral, umbilical, abdominal, diaphragmatic, incisional, epigastric, gastroesophageal, hiatal, intermuscular), muscle flap reinforcement, perforated tissue repair, and general tissue reconstruction (e.g., periosteum, thoracic wall, bladder wall, suture line reinforcement).

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.

510(k) Premarket Notification 510(k) Summary of Substantial Equivalence RE BIOABSORBABLE MESH

#### Device Description

The GORE BIOABSORBABLE MESH is used to reinforce soft tissue during the phases of wound healing by filling or bridging soft-tissue void spaces or defects. The GORE BIOABSORBABLE MESH elicits a physiological tissue response, which fills the defect with native tissue and gradually absorbs the device.

GORE® BIOABSORBABLE MESH is comprised of a microporous structure of synthetic bioabsorbable poly (67% glycolide: 33% trimethylene carbonate by weight) (PGA: TMC) copolymer fiber. This is the same material used in the predicate device (GORE DRAPEABLE ST Regenerative Membrane, K013346, cleared December 19, 2001 and SEAMGUARD, K030782 cleared April 21, 2003).

As packaged, the GORE BIOABSORBABLE MESH is a tailorable, bioabsorbable material intended to be a temporary bridge of defects until the absorptive nature of the device stimulates the body to fill the defect with native tissue. The device is available in sheets and preformed, three-dimensional shapes. The GORE BIOABSORBABLE MESH is provided STERILE for single use only.

Due to the absorptive nature of the GORE BIOABSORBABLE MESH, an overlay patch should be used in corrections requiring high strength (e.g., groin hernia repair)

#### Indication for Use

The GORE BIOABSORBABLE MESH is intended for use in the reinforcement of soft tissue. Examples of applications where the GORE BIOABSORBABLE MESH may be used include, but are not limited to:

GORE BIOABSORBABLE MESH

In W. L. Gore & Associates, Inc.'s opinion, the GORE BIOABSORBABLE MESH is believed to be substantially equivalent to the following predicate devices currently in interstate commerce with respect to comparable features, materials of construction and intended use.

- . SEAMGUARD Bioabsorbable Staple Line Reinforcement Material (W. L. Gore & Associates, Inc., Flagstaff, AZ) - K030782
- . GORE DRAPEABLE ST Regenerative Membrane (W.L. Gore & Associates, Inc., Flagstaff, AZ) - K013346
- . Vicryl (Ethicon Inc., Somerville, NJ) - K810428
- DePuy Restore® Orthobiologic Soft Tissue Implant (DePuy, Inc., . Warsaw, IN) - K001738
- . FortaGen (Organogenesis Inc., Canton, MA) - K021105

### Summary of Studies

W. L. Gore & Associates, Inc. performed device integrity testing to support that the GORE BIOABSORBABLE MESH is equivalent to the predicate devices. All device integrity test results for the GORE BIOABSORBABLE MESH met specified requirements.

## Conclusion (Statement of Equivalence)

Through data and information presented, numerous similarities support a determination of substantial equivalence, and therefore market clearance of the W. L. Gore & Associates, Inc. GORE BIOABSORBABLE MESH through this 510(k) Premarket Notification.
