The Model 171/172 Series Fetal Monitor is intended for monitoring fetal and maternal vital signs: fetal heart rate and maternal uterine activity, fetal movement detection, and an interface for select maternal NIBP monitors. The device is intended for use in a hospital/clinical environment.

AI/ML Overview

The provided text is a 510(k) summary for the Corometrics® Model 171/172 Fetal Monitor. It describes the device, its intended use, and comparison to predicate devices. However, it does not contain any information about acceptance criteria, a study proving the device meets acceptance criteria, or any of the specific details requested in your prompt related to the performance study (sample size, data provenance, ground truth, experts, adjudication, MRMC, standalone performance, training set, etc.).

The document explicitly states:

"To date, no performance standards relating to devices of this type have been promulgated by the Food and Drug Administration." This indicates that there are no FDA-mandated performance "acceptance criteria" for this device type.
"The Model 171/172 Series Fetal Monitor has been extensively tested to meet its requirements and design." While it mentions "extensively tested," it does not provide details of what those requirements were, the results of the tests, or a study demonstrating performance against specific criteria.

Therefore, I cannot populate the table or answer the specific questions about a performance study, as the necessary information is not present in the provided text.

Dear Mr. Cehovsky:

We have reviewed your Section 510(k) 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, 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 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.
