Device Description

AI/ML Overview

This appears to be a 510(k) clearance letter and related "Indications for Use" forms for various models of Medtronic Affinity NT Oxygenators. This type of document from the FDA does not contain the information requested about acceptance criteria and device performance studies (specifically, those related to AI/algorithm or human reader performance).

The purpose of a 510(k) clearance is to demonstrate substantial equivalence to a legally marketed predicate device, not necessarily to present detailed performance data in the context of controlled clinical trials or AI validation studies with specific acceptance criteria and ground truth methodologies.

Therefore, I cannot fulfill the request using only the provided text. The document is about:

Device Identification: Medtronic's Affinity NT Oxygenator series.
Regulatory Clearance: Confirmation of 510(k) clearance (K191029).
Indications for Use: The medical use (extracorporeal perfusion circuit for oxygenation, CO2 removal, and temperature control during CPB procedures up to 6 hours).
Regulatory Class: Class II device.
Prescription Use: All listed devices are prescription-use only.
General Controls: Reminders about compliance with FDA general controls (registration, listing, GMP, labeling, adverse event reporting, etc.).

There is no information in this document about:

Acceptance criteria table and reported device performance related to a study.
Sample size and data provenance for a test set.
Number or qualifications of experts for ground truth establishment.
Adjudication method.
Multi-reader multi-case (MRMC) comparative effectiveness study, or effect size with AI assistance.
Standalone (algorithm-only) performance.
Type of ground truth used (e.g., expert consensus, pathology, outcomes).
Sample size for training set.
How ground truth for the training set was established.

To provide the requested information, a different type of document would be needed, such as a detailed study report, a clinical trial summary (often found in PMA applications or supplement data, but not typically in a 510(k) summary for a Class II device like this oxygenator), or a specific AI/software validation report.

Dear Sammie Joseph-Fredericks:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

{1}------------------------------------------------

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.htm); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.

For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
