Indications for Use
CardiaMend™ Pericardial and Epicardial Reconstruction Matrix is intended for pericardial reconstruction and repair and for epicardial support and repair.
Device Story
CardiaMend™ is a porous, acellular, single-layer (1 ply) matrix derived from fetal bovine dermis; consists of naturally woven collagen fibers. Used for soft tissue reinforcement, repair, and reconstruction of pericardium and epicardium. Supplied as a dry, sterile rectangular sheet in various sizes; physician trims to size and rehydrates with sterile saline before implantation. Device acts as a scaffold for tissue repair; resorbable; non-crosslinked. Used by surgeons in clinical settings. Provides structural support during healing; promotes cellular infiltration.
Clinical Evidence
Bench testing included dimensional verification, tensile strength, elastic modulus, burst strength, suture pullout strength, cellular infiltration, porosity, and collagen denaturation. Biocompatibility testing per ISO 10993. GLP ovine study compared CardiaMend™ to CorMatrix Pericardial Patch (K051405); all animals survived with no test article-related abnormalities or adverse events. Viral inactivation, sterilization, and biocompatibility data leveraged from reference device SurgiMend™ (K071807).
Technological Characteristics
Acellular fetal bovine dermis collagen matrix; single-ply; non-chemically crosslinked. Resorbable. Supplied dry, terminally sterilized via ethylene oxide. Dimensions: 4x7 cm to 10x15 cm; thickness 0.40-1.54 mm. Biocompatibility per ISO 10993. Packaging validation per ISO 11607-1/2.
Indications for Use
Indicated for patients requiring pericardial reconstruction, repair, or epicardial support and repair.

{6}------------------------------------------------
As seen in the table above, the primary differences between the subject and predicate device are the animal tissue source, the available product sizes, number of layers, and thickness. These differences do not raise different questions of safety and effectiveness, and substantial equivalence to the predicate devices is demonstrated through verification and validation studies.
#### Performance Data VII.
The following performance data were provided in support of the substantial equivalence determination:
- Sterilization validation/re-qualification ●
- · EO/ECH residuals per ISO 10993-7
- Packaging validation and shelf-life per ISO 11607-1 and ISO 11607-2 ●
- Device Characterization Testing
- o Dimensional verification
- Tensile Strength O
- Tensile Stiffness/Elastic Modulus O
- Burst Strength O
- Suture Pullout Strength O
- Cellular Infiltration O
- O Porosity
- o Collagen Denaturation
- Design Validations ●
- o Usability Validation
- GLP Study in an Ovine Model
- The performance and safety of CardiaMend™ Pericardial and Epicardial O Reconstruction Matrix was evaluated in an ovine model compared to the predicate device, CorMatrix Pericardial Patch (K051405; marketed as ProxiCor for Pericardial Closure).
- All study objectives were met. The sheep did not exhibit any test article-related o abnormalities throughout the study. At the completion of the study, all animals survived and were evaluated as being in excellent health. There were no adverse events in any of the animals.
In addition, existing viral inactivation, sterilization, and biocompatibility data were leveraged from the reference SurgiMend™ Collagen Matrix for Soft Tissue Reconstruction (K071807) device, as the subject and reference devices are identical in material source, thickness, manufacturing, sterilization processes, and packaging.
{7}------------------------------------------------
## VIII. Conclusion
The subject device design was evaluated through biocompatibility, animal studies, and other performance testing to provide evidence of safe and effective use of CardiaMend™ Pericardial and Epicardial Reconstruction Matrix. CardiaMend™ Pericardial and Epicardial Reconstruction Matrix is substantially equivalent to the specified predicate devices based on comparisons of device functionality, technological characteristics, and indications for use.
