The Quantix/ND is a dual-beam, angle-independent, pulse-wave Doppler ultrasound system used for non-invasive (peripheral vessel) volume blood flow measurements, including blood flow velocity and volume blood flow. In addition to the conventional Doppler (blood flow velocity) measurements, the Quantix/ND technology utilizes special applications of ultrasound Doppler methods to obtain real-time measurements according to the definition of volume blood flow in target blood vessels. By definition, blood flow is the product of velocity and cross-sectional area. In other words, the volume blood flow is calculated by deriving flow velocity from the Doppler shift frequency using the basic standard formula and then multiplying the velocity by the cross-section area of the blood vessel.

AI/ML Overview

It is impossible to provide the requested information based on the input text. The provided text is a 510(k) premarket notification for the Quantix/ND Device, which focuses on demonstrating substantial equivalence to a predicate device.

The document does not contain:

Any specific acceptance criteria or performance metrics for the Quantix/ND device.
Details of a study proving the device meets acceptance criteria.
Information on sample sizes, data provenance, ground truth establishment, or expert qualifications for testing.
Any mention of multi-reader multi-case (MRMC) comparative effectiveness studies or standalone algorithm performance studies.

The document primarily describes the device, its intended use, and its technological characteristics in comparison to a predicate device (FlowGuard, K013803) to assert substantial equivalence, which is the basis for 510(k) clearance. Clinical performance data or detailed validation studies with defined acceptance criteria are not typically part of the summary provided in a 510(k) notification unless specifically requested or if substantial equivalence cannot be established through other means.

Quantix/ND Device Regulation Number: 870.2100 Regulation Name: Cardiovascular Blood Flowmeter Regulatory Class: II (two) Product Code: 74 DPW Dated: October 1, 2002 Received: October 15, 2002

Dear Mr. Stein:

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.

Page 2 - Mr. Ahava M. Stein

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 and additionally 21 CFR Part 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4646. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). 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
