Indications for Use
The CorMatrix® Tyke™ is intended for use in neonates and infants for repair of pericardial structures, as an epicardial covering for damaged or repaired cardiac structures, as a patch material for intracardiac defect and annulus repair, suture-line buttressing, and cardiac repair.
Device Story
CorMatrix Tyke is a 2-ply, lyophilized, sterilized sheet of small intestinal submucosa extracellular matrix (SIS-ECM) designed for pediatric cardiovascular repair. It serves as a patch or covering for cardiac structures, pericardium, and septal defects. Used by surgeons in clinical settings, the device provides a scaffold for tissue remodeling. It is applied during cardiac surgery to reinforce repairs or close defects. The device integrates with host tissue, promoting fibrocellular integration and formation of stable, endothelialized neointima. Benefits include structural support for cardiac repairs in neonates and infants, specifically tailored for lower-pressure applications compared to the 4-ply predicate.
Clinical Evidence
No human clinical data. Non-clinical evidence includes bench testing (tensile strength, suture retention, burst strength) and an in vivo animal study comparing 2-ply Tyke to 4-ply predicate. Histological evaluation at 90 and 180 days post-implantation showed structural integrity, fibrocellular integration, and stable, endothelialized neointima formation in both groups, demonstrating optimal healing.
Technological Characteristics
2-ply lyophilized SIS-ECM (small intestinal submucosa extracellular matrix) sheet. Dimensions: max 4 cm x 7 cm. Sterilized. Mechanical properties: tensile strength, suture retention, burst strength. No software or electronic components.
Indications for Use
Indicated for neonates and infants requiring repair of pericardial structures, epicardial covering, intracardiac defect/annulus repair, suture-line buttressing, and cardiac repair.
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.

## Predicate Devices
The CorMatrix® Tyke™ is substantially equivalent to CorMatrix® ECM® for Cardiac Tissue Repair, K063349.
## Device Description
CorMatrix® Tyke™ is intended for use in neonates and infants for repair of pericardial structures, as an epicardial covering for damaged or repaired cardiac structures, as a patch material for intracardiac defects, septal defect and annulus repair, suture-line buttressing, and cardiac repair.
CorMatrix® Tyke™ is derived from the same multi-laminate SIS-ECM material as the CorMatrix ECM for Cardiac Tissue Repair (4-ply). The CorMatrix® Tyke™ will be supplied as a 2-ply, lyophilized, sterilized sheet of SIS-ECM. With the exception of the differing layer counts, the device design and construction are identical to the FDA-cleared CorMatrix ECM for Cardiac Tissue Repair (K063349).
## Indications for Use
The CorMatrix Tyke™ is intended for use in neonates and infants for repair of pericardial structures, as an epicardial covering for damaged or repaired cardiac structures, as a patch material for intracardiac defects, septal defect and annulus repair, suture-line buttressing, and cardiac repair.

## CorMatrix Cardiovascular, Inc.
## CorMatrix® Tyke™ 510(k) Premarket Notification
## Substantial Equivalence
The device is constructed from the identical ECM material used for construction of the CorMatrix® ECM® for Cardiac Tissue Repair (K063349). The device differs from the CorMatrix® ECM® for Cardiac Tissue Repair only in the number of ECM layers from which each device is constructed.
The CorMatrix® Tyke™ is a two-layer ECM material and the CorMatrix® ECM® for Cardiac Tissue Repair is a 4-layer ECM material. Due to the handling and remodeling characteristics of the 2ply material, the CorMatrix® Tyke™ is well-suited for pediatric, lower-pressure applications. The Indications for Use are specific for the thinner ECM material by limiting use to lower-pressure applications. Due to the pediatic populations for which the CorMatrix® Tyke™ is intended, the device is provided in a maximum size of 4 cm x 7 cm whereas the predicate device (CorMatrix® ECM® for Cardiac Tissue Repair) is provided in sizes up to 7 cm x 20 cm.
Each layer of the device is identical to the ECM layers in the predicate device. However, the 2ply CorMatrix® Tyke™ was designed to address the needs of surgeons requesting a thinner ECM material.
The Indications for Use for the CorMatrix® Tyke™ also include pericardial closure. The CorMatrix RegeneSIS Pericardial Patch (K051405) is identical to the CorMatrix® ECM® for Cardiac Tissue Repair and was a predicate device for clearance of the CorMatrix® ECM® for Cardiac Tissue Repair.
## Non-clinical Testing
The CorMatrix® Tyke™ is intended for use as a reconstructive material for the repair and reconstruction of cardiac structures, including the pericardium. The performance testing conducted for the CorMatrix® Tyke™ includes tensile strength, suture retention, and burst strength testing. The testing demonstrated that the sterile CorMatrix® Tyke™ possesses adequate material properties for use in the indicated applications. The testing demonstrates that the material withstands the tension, and hemodynamic forces exerted on the material when used for pediatric cardiovascular repair, pericardial reconstruction, and venous cardiac outflow reconstruction.
A non-clinical investigational study was conducted to evaluate the in vivo performance of CorMatrix® Tyke™ patches. The CorMatrix Tyke (2-ply ECM material) was compared to the commercially available CorMatrix® ECM® for Cardiac Tissue Repair (4-ply ECM). Aortic and pulmonary artery implant sites were selected to correspond with the usual repair sites for which the CorMatrix® ECM® for Cardiac Tissue Repair is clinically used. Histological techniques were used to evaluate the structural integrity of both materials along with host cellular response during the remodeling process at 90 days and 180 days post-implantation.
## Conclusion
Performance testing of the CorMatrix® Tyke™ (2-ply ECM material) demonstrated that it exceeds the biomechanical requirements for its intended use as well as the biomechanical

510(k) Premarket Notification requirements of the CorMatrix® ECM® for Cardiac Tissue Repair (4-ply ECM material). The nonclinical study data demonstrated optimal healing features in both the Control (Cardiac Tissue Repair) and Test (Tyke) groups. The structural integrity of the arteriotomy sites were restored through fibrocellular integration of the ECM implant and formation of a fully mature, stable, and endothelialized neointima in both groups, and there were no adverse changes recorded.
The CorMatrix® Tyke™ is substantially equivalent to the CorMatrix® ECM® for Cardiac Tissue Repair.
