The summary describes a standard CT injector system with no mention of AI or ML capabilities, image processing, or data sets typically associated with AI/ML development.
No.
The device is used to inject contrast media for diagnostic studies in CT applications, not for therapy.
No
The device is described as an "Injector System" used for injecting contrast media for diagnostic studies, rather than performing the diagnostic analysis itself.
No
The device description explicitly states it is comprised of hardware components (Injector Head, Display Control Unit) in addition to software.
Based on the provided information, the Medrad Stellant CT Injector System is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "injecting intravenous contrast media into humans for diagnostic studies in computed tomography (CT) applications." This is an in vivo (within a living organism) application, not an in vitro (outside of a living organism, typically in a lab) diagnostic test.
- Device Description: The description focuses on components for injecting substances into a patient.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or performing tests on these samples outside of the body, which are hallmarks of IVD devices.
Therefore, the Medrad Stellant CT Injector System is a medical device used in conjunction with a diagnostic imaging modality (CT), but it is not an IVD itself.

(a)
Identification. An angiographic injector and syringe is a device that consists of a syringe and a high-pressure injector which are used to inject contrast material into the heart, great vessels, and coronary arteries to study the heart and vessels by x-ray photography.(b)
Classification. Class II (special controls). The device, when it is a non-patient contacting balloon inflation syringe intended only to inflate/deflate balloon catheters and monitor pressure within the balloon, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

The Medrad Stellant CT Injector System maintains the same intended use, similar operational 2) 767-2400 parameters, similar labeling and is used in a manner similar to the predicate device.
Like the EnVision, the Stellant is a syringe-based fluid delivery system indicated for delivery of contrast media during computed tomography procedures. It is intended to be used for the specific purpose of injecting intravenous contrast medium into the human vascular system for computed tomography studies.
The Stellant CT Injector System is comprised of the same main components as the predicate device: an Injector Head, a Display Control Unit, and sterile disposables.
Medrad has established, as part of its Quality System, design controls in compliance with FDA's Quality System Regulations (QSRs). These design controls are applied to all Medrad product development processes and product design changes. These design controls were applied to the development of the Stellant CT Injector and meet the requirements of the FDA's QSRs.
As part of the design control a risk analysis was performed, and design verification and validation testing was conducted to support the conclusion drawn by the risk analysis.
Test results demonstrate that the design specifications for the Stellant CT Injector System were met and that the Stellant CT Injector System meets the applicable requirements of the international standards cited. Therefore, it has been determined that the Stellant CT Injection is substantially equivalent to the predicate device, its predecessor, for its intended use when used as prescribed in the User Operation Manual.
A comparison of features and principles of operation between the proposed device and predicate device is provided in the table below.

Dear Mr. Pelc:
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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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); good manufacturing practice requirements as set

forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4635. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97) you may obtain. Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html
