Indications for Use

Peri-Strips is intended for use as a prosthesis for the surgical repair of soft tissue deficiencies using surgical staplers. Peri-Strips can be used to reinforce staple lines during lung resections including pneumonectorny, pneumoreduction, pneumectorny, lobectomies, segmentectomies (segmental resections), wedge resections, blebectomies, bronchial resections, and other lung incisions and excisions of lung and bronchus. It can also be used for the reinforcement of the gastric staple line during the bariatric surgical procedures of gastric bypass and gastric banding. Other soft tissue deficiencies amenable to repair with Peri-Strips include defects of the abdominal and thoracic wall, gastric banding, muscle flap reinforcement, rectal and vaginal prolapse, reconstruction of the pelvic floor, and hernias (including diaphragmatic, femoral, incisional, inguinal, lumbar, paracolostomy, scrotal, and umbilical hernias). Peri-Strips may be used with anastomotic staplers (when tissue division is desired) or with non-anastomotic staplers (when no tissue division is desired) according to the above indications.

Device Story

Peri-Strips and Peri-Strips Dry are surgical mesh patches derived from glutaraldehyde-crosslinked bovine pericardium. Configurations include tubular sleeves (for stapler use) and flat strips. Peri-Strips Dry undergoes vacuum dehydration and uses a hydrogel (PSD Gel) for stapler attachment. Devices are used by surgeons in OR settings to reinforce staple lines during lung and bariatric surgeries or to repair soft tissue deficiencies. The device acts as a mechanical reinforcement layer, sutured or affixed to surgical staplers to provide structural support to tissue during and after stapling. This reduces potential for staple line leaks or tissue tearing, benefiting patients by improving surgical outcomes in complex resections and bariatric procedures.

Clinical Evidence

Bench and animal testing only. Testing demonstrated no difference in safety or efficacy between NaOH-treated and non-NaOH-treated bovine pericardium tissue. No clinical trial data presented.

Technological Characteristics

Material: Glutaraldehyde-crosslinked bovine pericardium. Configurations: Sleeve (tubular) or strip (flat). Processing: Optional 1M NaOH treatment, rinsing, and neutralization; optional vacuum dehydration for 'Dry' version. Accessory: Hydrogel (PSD Gel) for Dry version. Application: Used with surgical staplers.

Indications for Use

Indicated for patients requiring soft tissue repair or staple line reinforcement during lung/bronchus resections (e.g., lobectomy, wedge resection, pneumonectomy) or bariatric procedures (gastric bypass, gastric banding). Also indicated for abdominal/thoracic wall defects, muscle flap reinforcement, prolapse repair, pelvic floor reconstruction, and various hernias.

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 Descriptions:

Peri-Strips (sleeve and strip) and Peri-Strips Dry are surgical mesh patches derived from bovine pericardium that is cross-linked with glutaraldehyde.

Peri-Strips comes in two configurations: Peri-Strips-sleeve and Peri-Strips-strip. Each unit of Peri-Strips-sleeve is composed of two strips of bovine pericardial tissue. After the final manufacturing step, each strip of pericardium is sewn to a polyolefin strip with polypropylene suture to create a tubular sleeve. The tubular configuration facilitates usage of the product with surgical staplers. The polyolefin strip and sutures are removed after the Peri-Strips-sleeve is secured in place. Peri-Strips-strip is a flat piece of bovine pericardium that is sutured to the stapler by the surgical team.

For Peri-Strips Dry (PSD), the bovine pericardial patch is manufactured in the form of a strip and undergoes an additional manufacturing step of dehydration by vacuum drying. The strip is affixed to the surgical stapler with the aid of a hydrogel (PSD Gel) supplied with the product.

Product may be treated with 1 molar sodium hydroxide (1M NaOH) for 60-75 minutes at 20-25°C, rinsed with deionized (DI) water, and neutralized with citrate solution, followed by a final DI water rinse. Bio-Vascular believes that product subjected to the NaOH treatment performs in a substantially

{1}------------------------------------------------

equivalent manner to non-NaOH-treated product, and that there is no difference in safety and efficacy between treated and non-treated tissue.

## Statement of Intended Use:

The indications for Peri-Strips (sleeve and strip) and Peri-Strips Dry are being expanded to include reinforcement of the gastric staple line during the bariatric surgical procedures of gastric bypass and gastric banding.

#### Summary/Comparison of Technological Characteristics:

These products are the same as the predicate devices except for the added indication of bariatric surgery.

The devices are comprised of bovine pericardium crosslinked with glutaraldehyde. They have an extensive clinical history of safe and effective use when used as surgical patches. Bench testing and animal testing show no difference in safety and efficacy between NaOH-treated and non-NaOHtreated tissue. Specifications of r NaOH-treated and non-NaOH-treated tissue are identical.

#### Safety and Effectiveness Conclusions:

These devices are substantially equivalent to the predicate devices with regard to safety and efficacy. No new questions of safety and efficacy are raised by the bariatric sugery indication.
