Intended Use

The SURGIS SLR Staple Line Reinforcement is intended for use as a prosthesis for the surgical repair of soft tissue deficiencies using surgical staplers. The device may be used for buttressing and reinforcing staple lines during lung resection (e.g. wedge resection, blebectomy, bullectomy, bronchial resection, segmentectomy, pneumonectomy/pneumectomy, pneumoreduction) and other incisions of the lung and bronchus. The device can be used for the reinforcement of the gastric staple line during bariatric surgical procedures of gastric bypass and gastric banding, and for reinforcement of staple lines during small bowel, mesentery, colon and colorectal procedures. The device may be used with anastomotic staplers or with non-anastomotic staplers.

#### III. PREDICATE DEVICE

SURGISIS® SLRTM Staple Line Reinforcement (K070405, Cook Biotech Incorporated)

### IV. DEVICE DESCRIPTION

The Biodesign® Staple Line Reinforcement device is part of a family of implant devices manufactured from porcine small intestine that are disinfected and processed to remove the tunica mucosa from the inner intestinal surface and tunica muscularis from the outer intestinal surface. The resulting membrane is a three dimensional, acellular, collagen-rich extracellular matrix (ECM) that is termed small intestinal submucosa (SIS). Biodesign® Staple Line Reinforcement consists of a thin multi-layer strip of SIS, pre-coated with an adhesive that eliminates the need for a separate adhesive (e.g. hydrogel) to affix the device to surgical stapler jaws. The single-use device is provided on a foam applicator and suspended in a form-fitting tray before being sealed in a foil pouch and sterilized (E-beam). The material composition, general manufacturing processes, packaging configuration and sterilization method of the subject device are identical to the predicate, SURGISIS® SLRTM Staple Line Reinforcement (K070405).

{4}------------------------------------------------

Upon implantation, the Biodesign® Staple Line Reinforcement device will provide mechanical reinforcement of the staple line by buttressing the soft tissue and preventing the surgical staples from tearing through the affected tissue. In addition, the Biodesign® Staple Line Reinforcement device will incorporate (remodel) into the body over time such that no graft material is left behind.

#### INDICATIONS FOR USE v.

The Biodesign® Staple Line Reinforcement is intended for use as a prosthesis for the surgical repair of soft tissue deficiencies using surgical staplers. The device may be used for buttressing and reinforcing staple lines during lung resection (e.g. wedge resection, blebectomy, lobectomy, bullectomy, bronchial resection, segmentectomy, pneumonectomy/pneumectomy, pneumoreduction) and other incisions and excisions of the lung and bronchus. The device can be used for the reinforcement of the gastric staple line during bariatric surgical procedures of gastric bypass and gastric banding, and for reinforcement of staple lines during small bowel, mesentery, colon and colorectal procedures. The device may be used with anastomotic staplers or with non-anastomotic staplers.

# VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The Biodesign® Staple Line Reinforcement device is identical to its predicate in that they are both intended for use as a prosthesis for the surgical repair of soft tissue deficiencies using surgical staplers. Moreover, the subject device's component materials, general manufacturing processes, fundamental scientific technology, and mode of action remain unchanged from the predicate.

The only modification to the Biodesign® Staple Line Reinforcement devices is the addition of thinner configurations (dimensional change) to the already existing line of staple line reinforcement devices. Table 5-1 provides a comparison of the subject and predicate devices.

### Table 5-1. Substantial Equivalence Information

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

### VII. PERFORMANCE DATA

The following performance data were provided in support of the substantial equivalence determination.

#### Biocompatibility testing

Biocompatibility of the predicate device has been established in accordance with ISO 10993-1:2009 – Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process to demonstrate that the device is safe for permanent contact (>30 days) implantation. The predicate test data was leveraged to support the substantial equivalence of the subject device as the device materials and general manufacturing processes are identical for the subject and predicate devices.

#### Non-Clinical testing

Product verification testing was performed on sterilized finished devices to evaluate the mechanical performance of the subject device for its intended use. Staple line leakage testing confirms that the Biodesign® Staple Line Reinforcement provides adequate staple line buttressing for use as a prosthesis for the surgical repair of soft tissue deficiencies using surgical staplers.

#### VIII. CONCLUSIONS

For purposes of determinations of substantial equivalence under section 513(i) of the FD&C Act (21 U.S.C. § 360c(i)), the Biodesign® Staple Line Reinforcement device has the same intended use and functions under the same mode of action and fundamental scientific technology as the predicate device. In addition, the subject device is composed of the same materials and manufactured using the same processes as the predicate. The only design modification is with regard to device dimensions, where the subject device includes thinner configurations to supplement the existing line of SIS staple line reinforcement devices. The absence of changes in the fundamental scientific technology and intended use of the device, as well as a risk analysis and completion of verification and validation activities, provide evidence to support the conclusion that the thickness modification does not introduce new risks and that the subject device performs comparably to the predicate device that is currently marketed for the same intended use.
