AI/ML Overview

This 510(k) submission (K972503) for California Medical Laboratories Inc. devices (Vessel Cannulas, Aortic Root Cannulas, and Cardioplegia Adapters) does not contain a study that establishes acceptance criteria and proves the device meets them in the way modern regulatory submissions typically do.

Instead, this is a Substantial Equivalence (SE) determination based on comparison to legally marketed predicate devices. The "study" here is essentially a comparison of technological characteristics and intended use to existing devices.

Therefore, many of the requested fields about quantitative performance, sample sizes, expert ground truth, adjudication, and MRMC studies are not applicable or cannot be extracted from this document.

Here's a breakdown of what can be inferred or directly stated from the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Inferred from Predicate Equivalence)	Reported Device Performance
Intended Use: - Deliver cardioplegia solution to the heart during cardiopulmonary bypass surgery. - Perfuse a vein graft or access patency in a harvested vein. - Aspirate air from the aorta (Aortic Root Cannula). - Vent the left heart (Aortic Root Cannula with Vent Line, "Y" Venting Adapter). - Connect cannulas/catheters to administration/vent lines (Straight Adapter). - Recirculate cardioplegia solution (Recirculation Adapter).	The devices have substantially equivalent intended uses as the predicate devices. This implies they perform these functions comparably.
Technological Characteristics: - Material (Polyvinyl Chloride). - Design elements (tapered tube, soft distal tip, anchor hubs, luer-lock, movable sew ring, flange with suture holes, introducer needle, "Y" connectors, tubing clamps, connecting adapters). - Availability with/without wings, check valve, vent line.	The devices have technologic characteristics which are substantially equivalent to the predicate device. This implies their design and material properties are comparable, leading to comparable performance.
Safety: (Implicit in SE determination)	The FDA's finding of substantial equivalence suggests the device is as safe as the predicate.
Effectiveness: (Implicit in SE determination)	The FDA's finding of substantial equivalence suggests the device is as effective as the predicate for its intended use.

2. Sample Size Used for the Test Set and Data Provenance

Not applicable. This submission is based on a comparison to existing predicate devices, not on a new clinical or laboratory test with a defined sample size in the traditional sense. The "test set" would implicitly be the body of evidence and performance of the predicate devices.
Data Provenance: Not specified. The reference is to "legally marketed devices" in interstate commerce prior to May 28, 1976, or reclassified devices. This implies historical data and established clinical use of the predicate devices.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of those Experts

Not applicable. The "ground truth" for this submission is the established safety and effectiveness of the predicate devices as determined by their long-standing market presence and regulatory clearance. There isn't a specific panel of experts establishing ground truth for a novel "test set" in this context. The FDA's review staff (e.g., Division of Cardiovascular, Respiratory, and Neurological Devices) makes the determination of substantial equivalence.

4. Adjudication Method for the Test Set

Not applicable. There was no independent test set requiring adjudication in the context of this 510(k) submission. The FDA's review process is its own form of "adjudication."

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This device is a physical medical device (cannulas and adapters), not an AI-powered diagnostic or therapeutic tool. Therefore, MRMC studies involving human readers and AI assistance are irrelevant to this submission.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

Not applicable. As stated above, this is a physical medical device, not an algorithm or AI system.

7. The Type of Ground Truth Used

Predicate Device Performance and Regulatory Status: The ground truth is the established safety, effectiveness, and regulatory clearance of the predicate devices (Research Medical, Inc. Vasoplegia Cannula, DLP, Inc. Aortic Root Cannula, DLP, Inc. "Y" Adapter-Coronary Perfusion, DLP, Inc. Straight Adapter, DLP, Inc. "Y" Adapters). The applicant is demonstrating that their new devices are sufficiently similar to these predicates that they can rely on the predicates' existing "ground truth" of performance.

8. The Sample Size for the Training Set

Not applicable. There is no "training set" in the context of this 510(k) submission for a physical medical device. Device development involves design, manufacturing, and testing, but not machine learning training sets.

9. How the Ground Truth for the Training Set was Established

Not applicable. See point 8.
