Vascular (4.0 and 8.0 MHz Probes) This product will be used to detect blood flow in veins and arteries for assisting in the detection of peripheral vascular disease.

Diagnostic ultrasound Imaging or fluid flow analysis of the human body as follows: Fetal (Mode of Operation: CWD); Peripheral Vascular (Mode of Operation: CWD)

Device Description

The LifeDop is a hand-held, battery powered, audio Doppler device used for detecting fetal heart beats and for blood flow detection in veins and arteries. The product includes four interchangeable probes (OB Late Term, OB Early Term, Vascular pencil probe, Vascular flat face probe) and user replaceable batteries. The user interface includes an on/off button, play/record button, volume control, single 2-1/4" speaker, headphone jack and LCD display for heart rate, battery and waveform information.

AI/ML Overview

The provided document is a 510(k) premarket notification for the Summit Doppler Systems LifeDop Doppler Ultrasound System. It asserts substantial equivalence to predicate devices and does NOT contain information about acceptance criteria or a study proving that the device meets those criteria.

Instead, the document focuses on:

Device Description and Intended Use: The LifeDop is a handheld, battery-powered audio Doppler device for detecting fetal heartbeats (obstetric) and blood flow in veins and arteries (peripheral vascular).
Predicate Devices: Huntleigh Technologies Manalapan, New Jersey Dopplex II Pocket Doppler (K930200) and Medasonics Incorporated Newark, California Cadance Doppler Ultrasound System (K991441).
Technology Summary: The core Doppler ultrasound technology is stated to be the same as the substantially equivalent predicate devices. The new technology in the LifeDop is an optional built-in audio recorder.
Clinical Testing: The document explicitly states "None provided."
Conclusion: The device is substantially equivalent based on comparisons of device features, materials, intended use, and performance.

Therefore, based on the provided text, there is no information regarding a study demonstrating the device meets specific acceptance criteria.

The request asks for various details related to acceptance criteria and performance studies. Since the document states "Clinical Testing: None provided" and relies on substantial equivalence to predicate devices rather than direct performance metrics against acceptance criteria, most of the requested information cannot be extracted.

Here's a breakdown of why specific points cannot be answered:

A table of acceptance criteria and the reported device performance: Not provided. The submission relies on substantial equivalence.
Sample sizes used for the test set and the data provenance: Not applicable, as no clinical testing was performed for this 510(k) submission.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
Adjudication method for the test set: Not applicable.
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 basic audio Doppler, not an AI system.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This device is not an algorithm.
The type of ground truth used: Not applicable.
The sample size for the training set: Not applicable. This device does not use a training set in the context of an AI/machine learning model.
How the ground truth for the training set was established: Not applicable.

Dear Mr. Job:

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 following transducers intended for use with the LifeDop Doppler Ultrasound System, as described in your premarket notification:

Transducer Model Number

2.1 MHz CW Fetal Probe 3.2 MHz CW Fetal Probe 4.0 MHz CW Peripheral Vascular Probe 8.0 MHz CW Peripheral Vascular Probe

{2}------------------------------------------------

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 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 (301) 594-4591. 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" (21 CFR Part 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers.

Regulation Number and Section

§ 884.2660 Fetal ultrasonic monitor and accessories.

(a)
Identification. A fetal ultrasonic monitor is a device designed to transmit and receive ultrasonic energy into and from the pregnant woman, usually by means of continuous wave (doppler) echoscopy. The device is used to represent some physiological condition or characteristic in a measured value over a period of time (e.g., perinatal monitoring during labor) or in an immediately perceptible form (e.g., use of the ultrasonic stethoscope). This generic type of device may include the following accessories: signal analysis and display equipment, electronic interfaces for other equipment, patient and equipment supports, and component parts. This generic type of device does not include devices used to image some relatively unchanging physiological structure or interpret a physiological condition, but does include devices which may be set to alarm automatically at a predetermined threshold value.(b)
Classification. Class II (performance standards).
