Device Description
The Meridian M100 Fetal Heart Rate Monitor is a modification of the cleared M1000 Fetal Heart Rate Monitor (K120018). The modifications are ones that do not affect the intended use or the fundamental scientific technology. The M100 Fetal Heart Rate Monitor is an AC powered fetal heart rate (FHR) monitor. The product consists of a signal processor containing hardware circuitry and software which acquires and processes analog signals using external, abdominal electrode sensors. Software algorithms extract ECG morphology and monitor fetal heart rate. The M100 connects to existing cleared fetal heart rate monitors with DECG (i.e., primary monitor) using the primary monitor's screen for display of fetal heart rate. The patient data is displayed real time on the primary monitor's display. The Meridian M100 is used as an accessory to a main/primary fetal monitor replacing the Doppler sensor on those monitors. The M100 is for use with the GE Corometrics 120 and the GE Corometrics 250 Fetal Monitors.
More Information

No.
The device is a monitor that measures and displays fetal heart rate; it does not provide any therapy or treatment.

Yes
The device measures and displays fetal heart rate (FHR) using abdominal surface electrodes, which is a physiological measurement used to assess fetal well-being, thus serving a diagnostic purpose.

No

The device description explicitly states that the product consists of a signal processor containing hardware circuitry and software, and it acquires and processes analog signals using external, abdominal electrode sensors. This indicates the presence of hardware components beyond just software.

Based on the provided information, the MindChild Medical Meridian M100 Fetal Heart Rate Monitor is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Meridian M100 Function: The Meridian M100 is an external device that measures fetal heart rate by detecting the fetal ECG signal from electrodes placed on the maternal abdomen. It does not analyze samples taken from the body.
  • Intended Use: The intended use is to monitor fetal heart rate during labor, which is a physiological measurement, not a diagnostic test performed on a biological sample.

Therefore, the Meridian M100 falls under the category of a medical device for physiological monitoring, not an in vitro diagnostic device.

Device Description

The Meridian M100 Fetal Heart Rate Monitor is a modification of the cleared M1000 Fetal Heart Rate Monitor (K120018). The modifications are ones that do not affect the intended use or the fundamental scientific technology. The M100 Fetal Heart Rate Monitor is an AC powered fetal heart rate (FHR) monitor. The product consists of a signal processor containing hardware circuitry and software which acquires and processes analog signals using external, abdominal electrode sensors. Software algorithms extract ECG morphology and monitor fetal heart rate.
The M100 connects to existing cleared fetal heart rate monitors with DECG (i.e., primary monitor) using the primary monitor's screen for display of fetal heart rate. The patient data is displayed real time on the primary monitor's display. The Meridian M100 is used as an accessory to a main/primary fetal monitor replacing the Doppler sensor on those monitors. The M100 is for use with the GE Corometrics 120 and the GE Corometrics 250 Fetal Monitors.

The M100 differs from the cleared M1000 in the following ways:

    1. The M100 has connection ports for connection of the M100 to existing cleared fetal heart rate monitors. Through these connections, the M100 uses the existing primary monitor's display for fetal heart rate whereas the M1000 incorporates a 24" LCD display,
    1. The M100 incorporates a standard input connection for a uterine contraction device. The M100 acts as a pass-through of this signal allowing for the uterine contraction data to be displayed on the primary monitor screen along with the fetal heart rate. The M1000 did not include this feature. Instead, viewing uterine contraction data required a separate monitor placed beside the M1000 device and viewing data on two screens. The M100 does not process uterine contraction signals but only synchronizes them to the fetal heart rate data.
    1. The primary monitor, to which the M100 is connected, is used for DECG measurements using a fetal scalp electrode should that be necessary. The M1000 had a dedicated DECG connection and adapter for a fetal scalp electrode.
    1. The M100 is set on a table top whereas the M1000 is housed within a rollup cart.

The algorithm used in the M100 to acquire and process fetal ECG signals through externally placed abdominal electrodes is the same as that used and clinically validated in the cleared M1000 device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Descriptive information, laboratory bench testing, electrical safety/EMC testing, and software validation were provided to demonstrate the device meets its design specifications, performs as intended, is safe for its intended use and that the modifications made from the M1000 device do not adversely affect safety and effectiveness.

The following testing was performed and met design specifications or criteria:

  • Dimensional Verification: To verify products meets specified dimensions and weight.
  • Fetal Heart Rate Output: Verify FHR output waveform for both minimum and maximum amplitude fetal heart output.
  • TOCO Output: Verify Toco output voltage for pressure application.
  • Packaging Testing: Verification of packaging and labeling.
  • Cable Pull Strength: Verify the cable connections are maintained when a 5 ft/lb. load is applied.
  • Drop Test: Verification that unit could sustain drop.
  • Push Test: Verify mechanical strength of enclosure by applying a 250N force to all sides and bottom of enclosure.
  • Cleaning: Verify that cleaning, disinfecting, and sterilizing the monitor in accordance with the instructions for doing so in the Operator's Manual and Service Manual do not create any hazards or hazardous situations. Ensure that cleaning substances are compatible with the M100.
  • Software Validation: Verify that all software modifications made performed as intended. Complete re-validation of the software was performed. Software validation demonstrated that the software performed according to design specifications, met requirement specifications and that there were no unintended effects due to any software modifications made.

Biocompatibility testing was not required as the M100 uses the same patient contacting materials as the cleared M1000 device.

Primary Monitor Compatibility: The M100 Monitor is intended to be used with the currently marketed GE Corometrics 120 and 250 Fetal Monitors. Compatibility testing was performed using the M100 monitor with each of the marketed primary monitors. Testing demonstrated the M100 is compatible with each of these monitors.

Electrical Safety and EMC: Electrical safety, electromagnetic compatibility, and usability testing was performed in accordance with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 60601-2-49, and IEC 62366. The M100 monitor met all test criteria.

Clinical Validation: The algorithm responsible for calculating fetal heart rate in the M100 Monitor is the same as that used in the cleared M1000 monitor. Further, the signal acquisition components (external electrodes) and signal processing software remain the same. The clinical validation of the software responsible for calculating FHR from fECG signals was performed in support of the cleared 510(k) for the M1000. This clinical validation is directly applicable to the modified design as the signal acquisition components (external electrodes) and the signal processing software and algorithm remains the same in the modified M100 device. Therefore, further clinical validation was not necessary for the modified device.

Biocompatibility Testing

Biocompatibility testing was not required as the M100 using the same patient contacting materials as that used in the cleared M1000 device.

Primary Monitor Compatibility

The M100 Monitor is intended to be used with the currently marketed GE Corometrics 120 and 250 Fetal Monitors. Compatibility testing was performed using the M100 monitor with each of the marketed primary monitors. Testing demonstrated the M100 is compatible with each of these monitors.

Electrical Safety and EMC

In addition, electrical safety, electromagnetic compatibility, and usability testing was performed in accordance with the following standards. The M100 monitor met all test criteria.

    1. IEC 60601-1 Medical electrical equipment Part 1: General requirements for basic safety and essential performance; IEC 60601-1: 2005 + CORR. 1 (2006) + CORR. 2 (2007)

    1. IEC 62366:2007(ed.1), Medical devices Application of usability engineering to medical devices (FDA recognized number: 5-67)

Clinical Validation

The algorithm responsible for calculating fetal heart rate in the M100 Monitor is the same as that used in the cleared M1000 monitor. Further, the signal acquisition components (external electrodes) and signal processing software remain the same. The clinical validation of the software responsible for calculating FHR from fECG signals was performed in support of the cleared 510(k) for the M1000. This clinical validation is directly applicable to the modified design as the signal acquisition components (external electrodes) and the signal processing software and algorithm remains the same in the

13

modified M100 device. Therefore further clinical validation was not necessary for the modified device.

Summary of Substantial Equivalence:

The design, intended use, principles of operation, and technological characteristics of the MindChild Meridian M100 device are substantially equivalent to those of the already cleared M1000 device. Substantial equivalence is based upon descriptive characteristics of the modifications and upon the testing conducted and summarized in this 510(k). The changes made resulting in the M100 device do not change the device's intended use or the fundamental scientific technology used and the testing performed in support of this notification demonstrate that the M100 device is substantially equivalent to the M1000 device.
