Intended Use

The Bard CollaMend Implant is indicated to reinforce soft tissue where weakness exists, e.g., for repair of hernia and chest wall defects, and for the surgical repair of damaged or ruptured soft tissue membranes.

Device Story

Bard CollaMend Implant is a sterile, lyophilized, acellular porcine dermal collagen sheet containing elastin fibers. Device is cross-linked to enhance strength and endurance. Intended for surgical reinforcement of soft tissue defects (e.g., hernia, chest wall). Surgeons must rehydrate the implant in sterile saline or lactated Ringer's solution for 3-5 minutes prior to implantation. Once implanted, the scaffold facilitates cellular infiltration and host tissue replacement, supporting soft tissue repair. Available in various sizes/shapes (4"x6" to 10"x14"); thickness approximately 1mm. Single-use device.

Clinical Evidence

Bench testing and animal implant studies were conducted. Biocompatibility testing confirmed the material is non-toxic and non-sensitizing. Animal studies compared functionality and in-growth characteristics against the Permacol Implant predicate, demonstrating consistent performance.

Technological Characteristics

Material: Lyophilized, acellular porcine dermal collagen and elastin fibers. Cross-linked for strength. Form factor: Sheet, ~1mm thick, various sizes. Energy source: None (mechanical). Connectivity: None. Sterilization: Sterile, single-use.

Indications for Use

Indicated for reinforcement of soft tissue where weakness exists, including hernia and chest wall defects, and surgical repair of damaged or ruptured soft tissue membranes in patients requiring such 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

• Permacol® Implant (Tissue Science Laboratories, PLC.)

#### D. Device Description

. .

The proposed device is a sterile, solid, sheet of lyophilized, accellular porcine dermal collagen and its constituent elastin fibers. It is processed to remove all non-collagenous cellular components and is cross-linked to increase strength and endurance. The proposed device allows cellular infiltration and replacement by host tissue, forming a strong repair of soft tissue defects. The proposed device will be made available in various sizes and shapes, ranging from a 4" x 6" ellipse to a 10" x 14" rectangle. The thickness of the devices will be approximately 1mm. Surgeons will need to rehydrate the product before implanting it into the patient. The proposed device will be marketed as a sterile, single use device.

## E. Intended Use

The Bard CollaMend Implant is indicated to reinforce soft tissue where weakness exists, e.g., for repair of hernia and chest wall defects, and for the surgical repair of damaged or runtured soft tissue membranes.

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

The proposed device and the three predicate devices are all generally intended for use in the repair of soft tissue deficiencies, including hermas

The proposed device is similar to the three predicate devices in principle of operation and general design. The key differences in the proposed device to the predicate devices are in the details of the device design.

Both the proposed device and the predicate Permacol Implant are manufactured from accllular porcine dermal collagen and its constituent clastin fibers. The predicate FortaGen Implant is manufactured from layers of purified porcine intestine, and the predicate Mersilene Mesh is manufactured from multifilament polyester.

The manufacturing processes for the proposed device, predicate Permacol Implant and FortaGen Implant are unique, but each of these processes contains decontamination/viral inactivation, cross-linking of the material, and sterilization of the device.

The proposed device must be completely hydrated before use by immersion in sterile saline solution or sterile lactated ringers solution for 3-5 minutes. The predicate Permacol Implant and FortaGen Implants are packaged moist for sterilization. The predicate Permacol Implant requires that the user rinse the implant before implantation in a patient, whereas the predicate FortaGen Implant does not require rinsing or rehydration of the implant unless the implant becomes dehydrated before implantation in a patient.

## G. Performance Data

Biocompatibility testing will be completed and passed before the Bard CollaMend Implant is released. These biocompatibility test results will show that the material used in the design and manufacture of the proposed device is non-toxic and non-sensitizing to biological tissues consistent with its intended use.

K152322

An animal implant study was performed to confirm the functionality and in-growth characteristics of the Bard CollaMend Implant as compared to the predicate Permacol Implant.

Laboratory test results demonstrate that the material chosen, the manufacturing process, and the design utilized for the Bard CollaMend Implant will meet the established specifications necessary for consistent performance during its intended use.
