#### DEVICE DESCRIPTION

The Harbor MedTech BriDGE Extracellular Collagen Matrix (ECM) Wound Dressing is a decellularized equine pericardial device that has been stabilized and radiation sterilized. The BriDGE ECM is non-pyrogenic and is provided sterile for single use only. The device must be rehydrated and rinsed prior to use following the procedure described in the Instructions for Use.

The BriDGE ECM is available in four sizes. The BriDGE ECM is available as a standard dressing and in a fenestrated model with pre-cut slits in the collagen matrix. A table of proposed model numbers and sizes is provided below:

| Model Number | Dimensions    | Description |
|--------------|---------------|-------------|
| HMT009       | 3 cm x 3 cm   | Standard    |
| HMT036       | 6 cm x 6 cm   | Standard    |
| HMT100       | 10 cm x 10 cm | Standard    |
| HMT150       | 10 cm x 15 cm | Standard    |
| HMT009F      | 3 cm x 3 cm   | Fenestrated |
| HMT036F      | 6 cm x 6 cm   | Fenestrated |
| HMT100F      | 10 cm x 10 cm | Fenestrated |
| HMT150F      | 10 cm x 15 cm | Fenestrated |

#### EQUIVALENCE TO MARKETED PRODUCT

Harbor MedTech, Inc., demonstrated that, for purposes of FDA's regulation of medical devices, the BriDGE Extracellular Collagen matrix (ECM) Wound Dressing is substantially equivalent in indications and design principles to predicate devices, each of which has been determined by FDA to be substantially equivalent to preamendment devices.

The Harbor MedTech BriDGE ECM Wound Dressing is substantially equivalent to the following predicate devices: Pegasus Biologics Inc., Unite™ Biomatrix Collagen Wound Dressing K071425, and Cook Biotech, Inc., Oasis Wound Dressing K061711.

The BriDGE Extracellular Collagen Matrix Wound Dressing has the same intended use as the predicate devices and incorporates the same basic design. The proposed device and the predicate devices are available as sheets in multiple sizes and are either sold pre-fenestrated (Pegasus) or may be fenestrated by the physician (Oasis). The BriDGE ECM undergoes a lyophilization process during manufacturing as does the Oasis predicate device. Device stabilization of the BriDGE ECM is achieved by using BDDGE, whereas the Pegasus predicate device uses EDC and the Oasis predicate device process is unknown. The BriDGE ECM and the Pegasus predicate device utilize equine pericardium and the Oasis predicate device utilizes porcine SIS.

#### PERFORMANCE TESTING

A number of preclinical studies were conducted to assess the physical attributes of the collagen biomaterial and manufacturing processing. Complete biocompatibility studies were conducted on the material. Results of all performance tests were found to be acceptable. The BriDGE Extracellular Collagen Matrix Wound Dressing is as safe and as effective as the predicate devices.

Biocompatibility testing was performed under Good Laboratory Practices (GLP) by NAmSA in accordance with the relevant parts of ISO 10993 Biological Evaluation of Medical Devices. All GLP testing met the criteria for biocompatibility. The testing criteria followed were based on the following medical device categorization: surface device, breached or compromised surface, prolonged contact (>24h to ≤30 days).

The following table summarizes the material testing performed.

#### Tensile Strength Testing

A study was conducted to compare the ultimate tensile strength of the BriDGE ECM to the predicate devices: Unite Biomatrix and Oasis Wound Matrix. Samples were rehydrated and pull tested for peak load (N). The tensile strength of the BriDGE ECM was equivalent to the Unite Biomatrix and significantly stronger than the Oasis Wound Matrix samples.

A study was conducted to determine the functional tensile strength characteristics of the fenestrated version of the BriDGE Extracellular Collagen Matrix. Samples were rehydrated and pull tested for peak load (N). The results were compared to the tensile strength data collected for the standard BriDGE Extracellular Collagen Matrix (non-fenestrated). The samples were pulled both vertically and horizontally. The results of the testing showed that the fenestrated

{3}------------------------------------------------

BriDGE ECM samples were comparable to the non-fenestrated BriDGE ECM samples and stronger than the Oasis Wound Matrix non-fenestrated samples.

#### Suture Pull-Out Testing

The BriDGE ECM was tested to characterize the device in terms of suture pull out resistance. The samples were hydrated and a 4-0 Prolene suture was attached and pull tested for peak load (N). Comparison testing was performed using samples of the predicate devices: Unite Biomatrix and Oasis Wound Dressing. The BriDGE ECM was found to be equivalent to the predicate devices in terms of suture pull-out strength.

Based on the results of the performance bench testing and comparison to predicate devices, Harbor MedTech has demonstrated that the BriDGE Extracellular Collagen Matrix Wound Dressing is equivalent to the predicate devices in terms of performance characteristics and will perform as intended for the application of the product.
