Intended Use

LTM-Perforated Surgical Mesh is intended for use as a soft tissue patch to reinforce soft tissue where weakness exists and for the surgical repair of damaged or ruptured soft tissue membranes. Indications for use include the repair of hernias and/ or body wall defects which require the use of reinforcing or bridging material to obtain the desired surgical outcome. LTM-Perforated Surgical Mesh is intended for single patient one-time use only.

Device Story

LTM-Perforated Surgical Mesh is a porcine-derived acellular dermal matrix used as a soft tissue patch for hernia and body wall defect repair. The device is processed in a phosphate-buffered aqueous solution with matrix stabilizers and provided in specific geometric configurations. It is a single-use, terminally sterilized sheet. The primary design modification from the predicate is the addition of a pre-defined pattern of perforations, created during the final die-cutting stage, to improve handling or integration while maintaining mechanical integrity. Used in healthcare facilities by surgeons, the mesh provides structural reinforcement to weakened or damaged tissue. The device is implanted to support the surgical repair, facilitating the desired clinical outcome for soft tissue reconstruction.

Clinical Evidence

No clinical testing was performed. Substantial equivalence is supported by bench testing comparing the subject device to the predicate. Bench evaluations included mesh thickness, tensile strength, device stiffness, suture pull-out strength, tear resistance (ASTM D5735-95), and burst strength (ASTM D6797-07). Results demonstrate that the perforated mesh maintains mechanical properties equivalent to the non-perforated predicate.

Technological Characteristics

Material: Porcine acellular dermal matrix. Preservation: Phosphate-buffered aqueous solution with matrix stabilizers. Form factor: Terminally sterilized sheet with pre-defined perforation pattern. Sterilization: Electron beam irradiation. Mechanical testing standards: ASTM D5735-95 (tear resistance), ASTM D6797-07 (burst strength).

Indications for Use

Indicated for patients requiring soft tissue reinforcement or repair of damaged/ruptured soft tissue membranes, including hernias and body 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.

#### DEVICE DESCRIPTION 4.

LTM-Perforated Surgical Mesh is a surgical mesh that is derived from porcine dermis and then processed and preserved in a patented phosphate buffered aqueous solution containing matrix stabilizers. The device is designed to perform as a surgical mesh for soft tissue repair. The device consists of a terminally sterilized sheet of processed porcine dermal matrix provided in prescribed geometric configurations and thicknesses. The device is packaged in a double pouch configuration, and is sterilized via electron beam irradiation. The device is considered a single use device which is to be used in a healthcare facility or hospital.

The subject device shares the same underlying scientific design as a porcine derived acellular dermal matrix, and has the same Intended Use, Indications for Use, and principles of operation as the cleared predicate device, LTM-Surgical Mesh (K070560). This 510(k) premarket notification describes a new design feature of the subject device, which introduces a pre-defined pattern of perforations throughout the tissue matrix.

### 5. INDICATIONS FOR USE

LTM-Perforated Surgical Mesh is intended for use as a soft tissue patch to reinforce soft tissue where weakness exists and for the surgical repair of damaged or ruptured soft tissue membranes. Indications for use include the repair of hernias and /or body wall defects which require the use of reinforcing or bridging material to obtain the desired surgical outcome.

LTM-Perforated Surgical Mesh is intended for single patient one-time use only.

### 6. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The subject device, LTM-Perforated Surgical Mesh, and the predicate device, LTM-Surgical Mesh (K070560), are both derived from porcine dermis and then processed and preserved in a patented phosphate buffered aqueous solution containing matrix stabilizers. The material type for both devices can be described as a porcine acelluar dermal matrix. Both devices consist of a terminally sterilized sheet of the processed porcine dermal matrix provided in prescribed geometric configurations and thicknesses. Both are packaged in a double pouch configuration and sterilized via electron beam irradiation.

The subject device, LTM-Perforated, and the predicate device, LTM-Surgical Mesh (K070560) share the same underlying scientific design as a porcine derived acellular dermal matrix, and have the same Intended Use, Indications for Use, and principles of operation. The predicate introduces a new design feature, a pre-defined pattern of perforations in the tissue matrix. The spacing and size of the perforations were specifically designed to maintain mechanical properties and meet the same established performance specifications as the predicate device, LTM-Surgical Mesh. The subject device utilizes the existing manufacturing processes of the predicate LTM-Surgical Mesh. Perforations are added to the tissue during the final die cutting stage at the time the device is cut to its final dimensions.

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

#### 7. PERFORMANCE

The predicate device, LTM-Surgical Mesh (K070560) has undergone appropriate biocompatibility testing, animal testing, and viral inactivation testing. The data demonstrates that the device is biocompatible and that the manufacturing process is capable of viral inactivation. The subject device, LTM- Perforated Surgical Mesh and the predicate device, LTM-Surgical Mesh (K070560) utilize the same raw materials (porcine dermis), processing components/solutions and manufacturing processes, and are identical except for the presence of perforations. Therefore, no further biocompatibility testing, animal testing, or viral inactivation testing was performed given that the presence of perforations does not change the biochemical or material properties of the surgical mesh.

# Bench Testing:

Bench testing was performed on the subject LTM-Perforated Surgical Mesh device to support substantial equivalence. Testing and/or evaluations included relevant elements of the FDA "Guidance for the Preparation of a Premarket Notification for a Surgical Mesh'" issued March 2, 1999. Table I includes the applicable product characterization criteria used to demonstrate substantial equivalence.

| Table 1: Substantial Equivalence Criteria | |
|-------------------------------------------|---------------------|
| Bench Testing /Evaluation | Applicable Standard |
| Mesh Thickness | N/A |
| Tensile Strength | N/A |
| Device Stiffness | N/A |
| Suture Pull-Out Strength | N/A |
| Tear Resistance | ASTM D5735-95 |
| Burst Strength | ASTM D6797-07 |

Performance data demonstrates that LTM-Perforated maintains similar mechanical properties and meets the established specifications as the predicate device. In addition, the LTM-Perforated Surgical Mesh shares the technological characteristics of perforations with other legally marketed reference devices. This new technological characteristic does not affect safety and efficacy of the device or raise new questions of safety or efficacy. LTM-Perforated Surgical Mesh meets the requirements to perform its intended use as a soft tissue patch and is substantially equivalent to the predicate device, LTM-Surgical Mesh (K070560).

# Clinical Testing:

No clinical testing was included in this submission.

#### 8. CONCLUSIONS

The subject device, LTM-Perforated Surgical Mesh, meets the requirements to perform its intended use as a soft tissue patch and is substantially equivalent to the legally marketed predicate device, LTM-Surgical Mesh (K070560).
