Indications for Use

The DURAFORM Dural Graft Implant is intended for use in procedures where the repair or substitution of the patient's dura mater is needed.

Device Story

DURAFORM Dural Graft Implant is a single-use, sterile collagen implant derived from processed bovine tendons. Designed as a sutureless, onlay graft for dural repair or substitution; tensionless sutures optional. Used by surgeons in clinical settings. Device provides a physical barrier for dural defects. Substantial equivalence established via shelf-life extension from 12 to 30 months compared to predicate. No changes to materials, design, or manufacturing process.

Clinical Evidence

No clinical or animal studies were performed. Substantial equivalence for the shelf-life extension was supported by bench-top device stability testing and packaging integrity testing.

Technological Characteristics

Single-use, sterile collagen implant derived from bovine tendons. Sutureless onlay graft design. Packaging integrity tested per ASTM F1929-12 and ASTM F88/F88M-09. No electronic components or software.

Indications for Use

Indicated for patients requiring repair or substitution of the dura mater during surgical procedures.

Regulatory Classification

Identification

A dura substitute is a sheet or material that is used to repair the dura mater (the membrane surrounding the brain).

| Test | Test Method Summary | Results |
|---------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Compressibility<br>(Time-Zero and<br>30-Month) | Compressibility quantifies the<br>ability of a device to be compressed.<br>Compressibility is measured by<br>comparing the compressed<br>thickness to the original thickness of<br>the device. The compressed<br>thickness is measured with a<br>thickness gage after compression at<br>120 seconds. | Both time-zero and<br>30-month real-time tests<br>passed the acceptance<br>criterion. Therefore, the<br>proposed device is<br>substantially equivalent to<br>the predicate device and<br>does not raise new issues in<br>safety and effectiveness. |
| Resilience<br>(Time-Zero and<br>30-Month) | Resilience quantifies the capability<br>of a device returning back to its<br>original state. Resilience is<br>measured by comparing the<br>recovered thickness after<br>compression to the original<br>thickness of the device. The<br>recovered thickness is measured<br>after the device has been<br>compressed for 120 seconds and left<br>to recover to its original state for<br>30 minutes. | Both time-zero and<br>30-month real-time tests<br>passed the acceptance<br>criterion. Therefore, the<br>proposed device is<br>substantially equivalent to<br>the predicate device and<br>does not raise new issues in<br>safety and effectiveness. |
| Test | Test Method Summary | Results |
| Imbibition<br>(Time-Zero and<br>30-Month) | The imbibition quotient measures<br>how much fluid a material is able to<br>absorb. In order to determine<br>imbibition quotient, the dividend of<br>the dry weight of a DURAFORM<br>Dural Graft Implant sample is taken<br>from wet weight of the sample after<br>10 seconds of irrigation, the<br>procedure representing clinical use. | Both time-zero and<br>30-month real-time tests<br>passed the acceptance<br>criterion. Therefore, the<br>proposed device is<br>substantially equivalent to<br>the predicate device and<br>does not raise new issues in<br>safety and effectiveness. |
| Apparent<br>Density<br>(Time-Zero and<br>30-Month) | Apparent density measures the<br>density of a dural substitute<br>material. Apparent density is<br>measured using the dry weight of<br>the device. | Both time-zero and<br>30-month real time tests<br>passed the acceptance<br>criterion. Therefore, the<br>proposed device is<br>substantially equivalent to<br>the predicate device and<br>does not raise new issues in<br>safety and effectiveness. |
| Visual<br>Inspection<br>(Time-Zero and<br>30-Month) | A visual inspection is performed for<br>the samples to be white in color<br>with no stains visible. | Both time-zero and<br>30-month real-time tests<br>passed the acceptance<br>criterion. Therefore, the<br>proposed device is<br>substantially equivalent to<br>the predicate device and<br>does not raise new issues in<br>safety and effectiveness. |
| Tensile<br>Strength<br>(Time-Zero and<br>30-Month) | Tensile strength testing is performed<br>on the DURAFORM Dural Graft<br>Implant per FDA's guidance on<br>physical and mechanical properties<br>testing for dura substitutes, as<br>outlined in the Guidance Document<br>for Dura Substitute Devices:<br>Guidance for Industry.<br>In order to test tensile strength, each<br>sample is wetted with water, placed<br>into an Instron instrument, and<br>rewetted to ensure the sample has<br>not dried out. Then, the instrument<br>pulls the sample and captures the<br>peak load when failure occurs. | Time-zero testing passed<br>the acceptance criteria;<br>30-month testing results<br>were deemed acceptable.<br>Therefore, the proposed<br>device is substantially<br>equivalent to the predicate<br>device and does not raise<br>new issues in safety and<br>effectiveness. |
| Test | Test Method Summary | Results |
| Visual<br>Inspection<br>(120-Month<br>and<br>132-Month) | A visual inspection is performed<br>for any damage to the packaging. | Both 120-month and<br>132-month tests passed the<br>acceptance criterion.<br>Therefore, packaging integrity<br>will be maintained for the<br>duration of the proposed shelf<br>life at 30 months. |
| Seal Integrity<br>(Dye<br>Penetration)<br>(120-Month<br>and<br>132-Month) | Seal integrity (dye penetration)<br>testing was tested in accordance<br>with ASTM F1929-12 Standard<br>Test Method for Detecting Seal<br>Leaks in Porous Medical<br>Packaging by Dye Penetration. | Both 120-month and<br>132-month tests passed the<br>acceptance criterion.<br>Therefore, packaging integrity<br>will be maintained for the<br>duration of the proposed shelf<br>life at 30 months. |
| Seal Strength<br>(120-Month<br>and<br>132-Month) | Seal strength testing was tested<br>in accordance with ASTM<br>F88/F88M-09 Standard Test<br>Method for Seal Strength of<br>Flexible Barrier Materials. | Both 120-month and<br>132-month tests passed the<br>acceptance criterion.<br>Therefore, packaging integrity<br>will be maintained for the<br>duration of the proposed shelf<br>life at 30 months. |

Performance Data (Cont.)

{6}------------------------------------------------

## VII. Performance Data (Cont.)

The following packaging stability testing, performed at 120 months and 132 months of real-time aging, was leveraged to support packaging integrity for the proposed shelf life at 30 months:

## Animal Testing:

No animal studies were performed as appropriate validation of the shelf life extension was achieved based on the comparison to the predicate device and from the results of the device and packaging stability studies.

## Clinical Testing:

No clinical studies were performed as appropriate validation of the shelf life extension was achieved based on the comparison to the predicate device and from the results of the device and packaging stability studies.

## Conclusion:

Based upon the indications for use, design, materials, packaging, comparison to the currently marketed device, and shelf life testing performed by Codman, it is concluded that the DURAFORM Dural Graft Implant with a 30-month shelf life is substantially equivalent to the predicate CODMAN Dural Graft Implant with a 12-month shelf life and therefore, does not raise any new issues of safety and effectiveness.
