The summary describes a standard extracorporeal oxygenator and reservoir for cardiopulmonary bypass, with no mention of AI or ML capabilities.
Yes
The device is used to oxygenate, remove carbon dioxide, and cool/warm blood during cardiopulmonary bypass procedures, which are therapeutic interventions.
No
Explanation: The device is an oxygenator and reservoir used for oxygenating, removing carbon dioxide, and controlling blood temperature during cardiopulmonary bypass procedures. It is involved in treating the blood, not diagnosing a condition.
No
The intended use and device description clearly describe a physical medical device (oxygenator, cardiotomy/venous reservoir) used in cardiopulmonary bypass procedures, not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used in an extracorporeal perfusion circuit to oxygenate, remove carbon dioxide, and cool/warm blood during cardiopulmonary bypass procedures. This is a direct interaction with the patient's blood outside the body for therapeutic purposes, not for diagnostic testing of samples.
- Lack of Diagnostic Language: The description does not mention any analysis of blood samples, detection of substances, or diagnostic purposes.
IVD devices are used to examine specimens (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device's function is therapeutic and supportive during a medical procedure.

Intended Use / Indications for Use
The Affinity NT oxygenator with Balance biosurface is intended to be used in an extracorporeal perfusion circuit to oxygenate and remove carbon dioxide from the blood and to cool or warm the blood during routine cardiopulmonary bypass (CPB) procedures up to 6 hours in duration.
The uncoated Affinity NT cardiotomy/venous reservoir (CVR) is intended to be used in an extracorporeal perfusion circuit to collect venous and cardiotomy suctioned blood during routine CPB procedures up to 6 hours in duration.

Trade/Device Name: Affinity NT Oxygenator with Balance Biosurface (Model 511B), Affinity NT Oxygenator with Balance Biosurface and Uncoated Cardiotomy/Venous Reservoir (Model 541B) Regulation Number: 21 CFR 870.4350 Regulation Name: Cardiopulmonary bypass oxygenator Regulatory Class: Class II Product Code: DTZ Dated: August 28, 2019 Received: August 29, 2019
Dear Harsh Dharamshi:
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.
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/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); 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 https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). 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 (https://www.fda.gov/medical-device-advice-comprehensive-regulatoryassistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).
