Intended Use

CorMatrix(R) Cor Patch is intended for epicardial tissue support and repair.

Device Description

CorMatrix Cor Patch is intended for epicardial tissue support and repair.

CorMatrix Cor Patch is derived from the same multi-laminate SIS-ECM material as the CorMatrix Tyke (2-ply, non-pressed). The CorMatrix® Cor Patch will be supplied as a 4-ply, lyophilized, sterilized sheet of SIS-ECM. With the exception of the differing layer counts and a change to the manufacturing process for the Cor Patch which does not result in a change to the fundamental technology of the device, the device design and construction are identical to the FDA-cleared CorMatrix® Tyke™ (K152127).

AI/ML Overview

This document is a 510(k) premarket notification for a medical device called CorMatrix Cor Patch. It describes the device, its intended use, and argues for its substantial equivalence to a previously cleared predicate device, the CorMatrix Tyke.

However, this document does not contain the information required to answer your specific questions regarding acceptance criteria and a study proving a device meets these criteria in the context of an AI/ML medical device.

Here's why and what's missing:

  • Device Type: The CorMatrix Cor Patch is a biological patch made from porcine extracellular matrix material for epicardial tissue support and repair. It is a physical medical device, not an AI/ML algorithm or software.
  • Study Type: The "Non-clinical Testing" section describes material property testing (tensile strength, suture retention, burst strength) to demonstrate adequate material properties, not a clinical study involving human or even simulated human-in-the-loop performance with an AI system.
  • Acceptance Criteria: The document mentions that the testing "demonstrates that the sterile SIS-ECM of the Cor Patch possesses adequate material properties for use in the indicated applications" and "exceeds the biomechanical requirements for its intended use." However, it does not provide a specific table of acceptance criteria with quantitative thresholds for AI performance metrics (like sensitivity, specificity, AUC, human reader improvement).
  • Ground Truth, Experts, Adjudication, MRMC, Standalone Performance: These concepts are relevant to the evaluation of AI/ML algorithms, where the performance of the algorithm is compared against a "ground truth" established by human experts, pathology, or outcomes data. This document does not describe such studies because the device is a physical patch.
  • Sample Size (for AI training/test sets): The document refers to "testing" but does not specify sample sizes in the context of test or training sets for an AI algorithm.
  • Data Provenance: Not applicable in the context of material property testing for a physical device.

In summary, the provided text is about a physical medical device (a tissue patch) and its material properties, not about an AI/ML medical device and its performance evaluation against established acceptance criteria.

Therefore, I cannot extract the requested information from this document. If you provide a document that describes the development and validation of an AI/ML medical device, I would be happy to help answer your questions.

Predicate Devices

The CorMatrix® Cor Patch is substantially equivalent to the CorMatrix® Tyke®, K152127.

Device Description

CorMatrix Cor Patch is intended for epicardial tissue support and repair.

CorMatrix Cor Patch is derived from the same multi-laminate SIS-ECM material as the CorMatrix Tyke (2-ply, non-pressed). The CorMatrix® Cor Patch will be supplied as a 4-ply, lyophilized, sterilized sheet of SIS-ECM. With the exception of the differing layer counts and a change to the manufacturing process for the Cor Patch which does not result in a change to the fundamental technology of the device, the device design and construction are identical to the FDA-cleared CorMatrix® Tyke™ (K152127).

Indications for Use

The CorMatrix Cor Patch is intended for epicardial tissue support and repair.

Substantial Equivalence

The device is constructed from the same SIS-ECM material used for construction of the CorMatrix Tyke (K152127). The device differs from the CorMatrix Tyke only in the number of ECM layers from which

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

each device is constructed, and additional processing (wash) steps for the Cor Patch device which serve to further remove impurities from the SIS-ECM.

The CorMatrix Cor Patch is a four-layer ECM material, and the CorMatrix Tyke is a two-layer ECM material. The CorMatrix Tyke is intended for use in neonates and infants, and is therefore provided in a maximum size of 4 cm x 7 cm, whereas the CorMatrix Cor Patch is provided in sizes up to 7 cm x 10 cm. Each layer of the Cor Patch device is identical to the ECM layers in the predicate device, with the exception of the additional processing step performed for the Cor Patch product.

The Indications for Use for the predicate CorMatrix Tyke include use as an epicardial covering for damaged or repaired cardiac structures; the Cor Patch is intended for epicardial tissue support and repair.

Non-clinical Testing

The CorMatrix Cor Patch is intended for epicardial tissue support and repair. The performance testing that supports the Cor Patch includes tensile strength, suture retention, and burst strength testing. The testing demonstrates that the sterile SIS-ECM of the Cor Patch possesses adequate material properties for use in the indicated applications.

Conclusion

Performance testing of the SIS-ECM material of the Cor Patch demonstrated that it exceeds the biomechanical requirements for its intended use.

The CorMatrix Cor Patch is substantially equivalent to the CorMatrix Tyke; both are intended for epicardial support and repair and are made from porcine SIS-ECM. The Cor Patch undergoes an additional processing step which serves to further remove impurities from the base material, but does not result in a change to the fundamental technology of the devices.
