Intended Use

CardioCel is indicated for use as a patch in pericardial closure and the repair of cardiac and vascular defects including intracardiac defects; septal defects, valve and annulus repair; great vessel reconstruction, peripheral vascular reconstruction and suture line buttressing.

Device Story

CardioCel is a sterile, pre-cut, flat sheet of acellular bovine pericardium; processed via ADAPT® TEP technology using glutaraldehyde crosslinking. Used in hospital settings during open-heart surgery by surgeons for cardiovascular reconstruction and repair. Implanted as a long-term patch to maintain structural integrity of repaired tissue; supports tissue remodeling without calcification. Benefits include durable repair of cardiac/vascular defects and favorable hemodynamic performance in high-pressure environments.

Clinical Evidence

Clinical study of 30 pediatric patients with congenital cardiac anomalies demonstrated safety and efficacy. Primary endpoints included durability, hemodynamic properties, and absence of calcification. Results showed no graft-related morbidity or mortality up to 36 months post-surgery. Non-clinical evidence includes pivotal sheep model studies showing effective repair of jugular vein and heart valve defects with tissue remodeling and no calcification. Bench testing confirmed functional stability (burst/tensile strength) and biocompatibility per ISO 10993.

Technological Characteristics

Material: Glutaraldehyde-crosslinked bovine pericardium. Form: Sterile, moist, pre-cut flat sheet (4x4 cm, 5x8 cm, 14x7 cm). Principle: ADAPT® TEP technology for crosslinking. Sterilization: Propylene oxide. Biocompatibility: ISO 10993 compliant. Intended as a long-term implant for cardiovascular repair.

Indications for Use

Indicated for pediatric and adult patients requiring surgical repair of pericardial, cardiac, and vascular defects, including intracardiac, septal, valve, annulus, great vessel, and peripheral vascular defects, and for suture line buttressing.

Regulatory Classification

Identification

An intracardiac patch or pledget made of polypropylene, polyethylene terephthalate, or polytetrafluoroethylene is a fabric device placed in the heart that is used to repair septal defects, for patch grafting, to repair tissue, and to buttress sutures.

Image /page/1/Picture/0 description: The image shows the word "ADMEDUS" in a bold, sans-serif font. The letters are all capitalized and black. The "A" is stylized with a small triangle inside.

CardioCel has a shelf life of 24 months when stored between 2°C - 25°C.

CardioCel is supplied in three sizes: 4 x 4 cm, 5 x 8 cm and 14 x 7 cm.

### INDICATIONS FOR USE:

CardioCel is indicated for use as a patch in pericardial closure and the repair of cardiac and vascular defects including intracardiac defects; septal defects, valve and annulus repair; great vessel reconstruction, peripheral vascular reconstruction and suture line buttressing.

### COMPARATIVE ANALYSIS:

CardioCel is manufactured from glutaraldehyde crosslinked bovine pericardium, which is the same material used for the predicate devices. CardioCel is considered to be substantially equivalent to the predicates for the following reasons:

- Same raw material. .
- Same intended use. .
- Used in the same patient population. .
- Used in the same clinical environment. .
- . Manufactured using the same principles of crosslinking with glutaraldehyde.
- Used in the same anatomical region (cardiovascular system). .
- t Intended to perform as a long term implant, maintaining the integrity of the area repaired.
- . Operates using the same fundamental scientific technology.
- . Supplied in several sizes.
- Similar manufacturing process .
- Similar sterilisation method to one predicate. .
- Similar packaging and labeling. .

Please see Table 1 for a comparison of CardioCel to the Edwards Bovine Pericardial Patch (K082139) and the CV Peri-Guard Cardiovascular Patch (K971726).

The safety and effectiveness of glutaraldehyde-crosslinked bovine pericardium patches for cardiovascular reconstruction and repair is well established. Cardiovascular patches have proved to be effective in achieving the desired results and are well tolerated by the host tissue.

#### SUBSTANTIAL EQUIVALENCE INFORMATION:

#### Bench testing

CardioCel functional testing including burst strength, suture retention strength, tensile strength, crosslink stability and pronase digestion testing has demonstrated that CardioCel is a consistent, stable patch material suitable for cardiovascular repair in high pressure environments. Side by side studies of burst strength, crosslink stability and pronase digestion have demonstrated that CardioCel is substantially equivalent the predicate devices.

#### Biocompatibility

The biocompatibility of gluraldehyde-crosslinked bovine pericardium patches is wellestablished by a long history of clinical use in cardiovascular applications. Biocompatibility testing according to the requirements of ISO 10993 confirmed that CardioCel exhibited favorable biocompatibility characteristics in common with the predicate devices.

#### Non-clinical studies

CardioCel has been evaluated in small and large animal models for biocompatibility, safety and performance. Pivotal studies in sheep models demonstrated that CardioCel provided effective and durable repair of jugular vein defects and both mitral and pulmonary heart valve defects. The biocompatible properties of CardioCel allowed tissue remodeling in and around the implant and preservation of valve function. without calcification. The safety and performance characteristics of CardioCel in a high pressure hemodynamic environment compare favorably with published animal studies using predicate devices.

#### Clinical studies

A clinical study of 30 pediatric patients requiring surgical repair of a range of congenital cardiac anomalies was undertaken to assess the safety and efficacy of CardioCel as an intracardiac repair patch. CardioCel showed durability, efficacy and favorable hemodynamic properties. There was no graft related morbidity or mortality and no evidence of calcification up to 36 months after surgery. The clinical performance of CardioCel compares favorably with clinical studies using predicate devices.

Information from bench testing, biocompatibility testing, non-clinical studies and clinical studies support the claim that Cardiovascular patch is substantially equivalent to marketed devices including the Edwards Bovine Pericardial Patch (K082139) and the CV Peri-Guard Cardiovascular Patch (K971726).
