Diagnostic ultrasound blood flow detection of the human body. The Stethoflux is designed for use by general practitioners or specialists on their own responsibility. It allows dual stethoscopic and doppler peripheral vascular investigation in a simple auscultation. It facilitates: - the detection of blood-flow in the peripheral arteries - Systolic Blood Pressures (SBP) measurements of the lower limb and upper-limb in order to determine the possible PAD ankle Brachial index (ABI) in the concerned limb. when associated with a sphygmomanometer
Acoustic stethoscope with ultrasonic transducer. It operates with 2 modes stethoscopic mode (classical stethoscope) and Doppler mode. Powered by one (6LR61) 9V lenium battery. Doppler frequency: 8 MHz. Operating time 25 h according to use. Mass 331 g.
The provided document is a 510(K) Premarket Notification Submission for the "Acoustic and Doppler Stethoscope Stethoflux®". It states that the device is substantially equivalent to a predicate device (K030466, HandyDop TM, Elcat GmbH) and does not provide detailed acceptance criteria or a dedicated study description with specific performance metrics beyond stating "Similar specifications for the common application with the 8 MHz probe."
The document explicitly states:
- "There are no section 514 performance standards for this class of device for assisting in the determination of its substantial equivalence."
- "Not required for determination of substantial equivalence for this class of device, though publication of some clinical data are contained in this premarket submission." (However, these clinical data are not present in the provided text.)
Therefore, based on the information provided, it is not possible to complete most of the requested sections as the submission relies on demonstrating substantial equivalence rather than meeting pre-defined acceptance criteria through detailed performance studies.
Here's what can be extracted and what cannot:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria | Reported Device Performance (Stethoflux®) |
|---|---|
| Not specified. The submission relies on substantial equivalence to predicate device. | "Similar specifications for the common application with the 8 MHz probe" as the predicate device (K030466, HandyDop TM). |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not provided in the document. The text states that performance standards and clinical/non-clinical test data are "Not required for determination of substantial equivalence for this class of device."
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not provided in the document.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not provided in the document.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device is a doppler stethoscope, not an AI device. No MRMC study or AI assistance is mentioned.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a medical device, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not provided in the document.
8. The sample size for the training set
Not applicable. No algorithm or AI is mentioned, so no training set.
9. How the ground truth for the training set was established
Not applicable. No algorithm or AI is mentioned.

Re: K060064
Trade Name: Stethoflux® Regulation Number: 21 CFR 892.1540 Regulation Name: Nonfetal ultrasonic monitor Regulatory Class: II Product Code: JAF Dated: December 29, 2005 Received: January 9, 2006
Dear Mr. LAPRELLE:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we 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). 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.
This determination of substantial equivalence applies to the Stethoflux® and 8 MHz CW Split Crystal transducer as described in your premarket notification.
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)
Image /page/2/Picture/12 description: The image shows a circular logo with the text "1906-2006" at the top and "FDA Centennial" in the center. The logo is surrounded by a dotted border and contains the letters "FDA" in a bold, stylized font. The logo appears to be a commemorative emblem for the centennial anniversary of the Food and Drug Administration.

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 predicate device results in a classification for your device and thus permits your device to proceed to market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. 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 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/industry/support/index.html

§ 892.1540 Nonfetal ultrasonic monitor.
(a)
Identification. A nonfetal ultrasonic monitor is a device that projects a continuous high-frequency sound wave into body tissue other than a fetus to determine frequency changes (doppler shift) in the reflected wave and is intended for use in the investigation of nonfetal blood flow and other nonfetal body tissues in motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II.
