Device Description

The subject devices Philips Avalon Fetal Monitors FM20 and FM30 are modification of the legally marketed Philips Series 50XM (M1350B) Fetal/Maternal Monitor (K954351) and offer monitoring of fetal and maternal heart rates, uterine activity, maternal ECG, maternal non-invasive blood pressure (NIBP) and oxygen saturation (Sp02) during antepartum testing and labor and delivery. The Avalon FM20 and FM30 are intended for non-invasive and invasive monitoring of the physiological parameters of pregnant women during antepartum testing and labor and delivery. The Avalon FM20 and FM30 are intended for monitoring fetal and maternal heart rates, uterine activity, maternal non-invasive blood pressure (NIBP) and oxygen saturation (SpO2). The Avalon FM20 and FM30 are intended for generating alarms, for displaying, storing and recording patient data and related waves.

AI/ML Overview

Here's an analysis of the provided text regarding acceptance criteria and the study that proves the device meets them:

1. A table of acceptance criteria and the reported device performance

The provided text does not explicitly list specific quantitative acceptance criteria or detailed performance metrics. Instead, it makes a general statement:

Acceptance Criteria Category	Reported Device Performance
Performance, Functionality, Reliability	"meet all reliability requirements and performance claims." "Pass/Fail criteria were based on the specifications cleared for the predicate device and test results showed substantial equivalence."

Explanation: The submission is for a modified device (Philips Avalon Fetal Monitors FM20 and FM30) that is stated to have the "same technological characteristics" and "same intended use" as legally marketed predicate devices. The "acceptance criteria" here are implicitly tied to demonstrating that the modified device performs equivalently to the predicate devices and meets their established specifications. The text confirms that this equivalence was met.

2. Sample size used for the test set and the data provenance

Sample Size: Not specified.
Data Provenance: Not specified (e.g., country of origin, retrospective or prospective).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. The submission describes verification, validation, and testing activities against predicate device specifications, not a clinical study involving experts establishing ground truth for diagnostic accuracy.

4. Adjudication method for the test set

Not applicable. The submission describes engineering and system-level testing, not a clinical study requiring adjudication of expert interpretations.

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 is not an AI-powered diagnostic device, and no MRMC comparative effectiveness study is mentioned. The device is a fetal monitor.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

The device itself is a standalone fetal monitor designed to provide physiological data. Its "standalone" performance was assessed through system-level, performance, and safety tests against predicate device specifications. There is no "algorithm only" performance reported in the context of AI.

7. The type of ground truth used

The "ground truth" for the device's performance was established by the specifications cleared for the predicate device. The testing demonstrated that the modified device met these existing specifications.

8. The sample size for the training set

Not applicable. This is not a machine learning or AI device that requires a training set.

9. How the ground truth for the training set was established

Not applicable, as there is no training set for this type of device.

Dear Mr. Stacha:

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 (Premarket Approval), 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 vour device in the Federal Register.

Please be advised that FI)A 's issuance of a substantial equivalence determination does not mean that FIDA 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.

{4}------------------------------------------------

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 one of the following numbers, based on the regulation number at the top of this letter:
