The description focuses on standard Doppler ultrasound principles and calculations (velocity * area) without mentioning any AI/ML components or algorithms.
No
The device is described as being for "Diagnostic blood flow measurements" and "non-invasive, peripheral vessel examinations and intraoperative examinations of blood flow measurements," which indicates a diagnostic rather than therapeutic purpose.
Yes
The "Intended Use: Diagnostic blood flow measurements" explicitly states its diagnostic purpose.
No
The device description explicitly states it is a "dual-beam, angle-independent, pulse-wave Doppler ultrasound system," which indicates it is a hardware device that utilizes ultrasound technology.
Based on the provided information, the FlowGuard device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are performed outside of the living organism.
- FlowGuard's Function: The FlowGuard device is described as a non-invasive and intraoperative ultrasound system used for measuring blood flow within the body. It directly interacts with the patient's blood vessels to obtain measurements.
Therefore, because the FlowGuard device operates in vivo (within the living body) rather than in vitro (outside the body on a sample), it does not fit the definition of an In Vitro Diagnostic device.

Device Description
The FlowGuard is a dual-beam, angle-independent, pulse-wave Doppler ultrasound system used for non-invasive (peripheral vessel) and intra-operative volume blood flow measurements, including blood flow velocity and volume blood flow. In addition to the conventional Doppler (blood flow velocity) measurements, the FlowGuard 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.

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 determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G, (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.
The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:
Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850
This letter will allow you to begin marketing your device as described in your premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed nredicate device results in a classification for your device and thus permits your device to proceed to market.
