Intended Use
I. Fetal Surveillance The Corometrics® Model 171/172 Series Monitors are used for monitoring of the fetus during the antepartum period as well as throughout labor and delivery (i.e. fetal heart rate and uterine activity monitoring). The device also has an optional monitoring mode to detect fetal body movements. II. Maternal NBP Recording Blood Pressure. The monitor has an interface to select external NBP monitors. The Monitor does not process any NBP data but only prints the NBP data , from the external monitor, to its chart recorder.
Device Description
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.
More Information

No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the device description focuses on standard vital sign monitoring without mentioning any advanced processing or learning capabilities.

No
The device is used for monitoring fetal and maternal vital signs, not for treating any condition.

Yes
The device monitors fetal heart rate, uterine activity, and fetal body movements, which are all diagnostic indicators of fetal well-being. It also records maternal NBP data, further contributing to diagnosis.

No

The device description explicitly states it is a "Model 171/172 Series Fetal Monitor," which is a hardware device with interfaces for external monitors and a chart recorder. It is not described as software only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • This device monitors physiological signals directly from the patient (fetal heart rate, uterine activity, fetal movement, maternal blood pressure). It is a physiological monitoring device, not a device that analyzes biological samples.

The intended use and device description clearly indicate that it is used for monitoring the fetus and mother during pregnancy and labor by measuring vital signs directly from the body.

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.
