The description focuses on signal processing (filtering, amplification, analysis, recording, display) using a LabVIEW-based program on a laptop, without mentioning AI or ML techniques. The performance studies compare the device's output to existing technologies and a gold standard, not evaluating an AI/ML model's performance.
No
The device is described as a monitor intended to measure and display uterine activity, not to provide therapy.
Yes.
The device measures intrapartum uterine activity in women who are at term and in labor, using electromyography (EMG) signals from the maternal abdomen. This measurement helps healthcare professionals monitor uterine activity, which is a diagnostic function in assessing the progress of labor.
No
The device description explicitly states it consists of a "Signal Conditioning Module specifically designed to collect, filter, and amplify the electromyographical (EMG) signal" which contains "electronic components designed to receive a physiological signal from a set of Ag/AgCl surface electrodes". This indicates the presence of hardware components beyond just software.
Based on the provided information, the SureCALL® EMG Labor Monitor® is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
- SureCALL® Function: The SureCALL® EMG Labor Monitor® measures uterine activity by detecting electrical signals (EMG) from the maternal abdomen using surface electrodes. This is a non-invasive measurement taken directly from the body, not from a specimen.
Therefore, the SureCALL® EMG Labor Monitor® falls under the category of a medical device used for physiological monitoring, not an IVD.

Description of the test set, sample size, data source, and annotation protocol
The primary study supporting the effectiveness of the SureCALL® monitor involved 20 women at term, in labor, at three clinical sites. Each study subject was instrumented with three technologies for measuring uterine activity:
- (1) a tocodynamometer (toco) attached to the maternal abdomen
- (2) a set of abdominal surface electrodes for uterine electromyography (SureCALL®), and
- (3) an intrauterine pressure catheter (IUPC).
Using IUPC as the 'gold standard', this study methodology allowed a three-way comparison for evaluating how well the SureCALL® system performed vis-a-vis the toco technology.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical Study: 20 women at term, in labor, at three clinical sites. Each study subject was instrumented with a tocodynamometer (toco), a set of abdominal surface electrodes for uterine electromyography (SureCALL®), and an intrauterine pressure catheter (IUPC) as the 'gold standard'. The study compared the SureCALL® system's performance against toco technology.
MRMC Study: After completion of the clinical study, the three different monitor tracings were evaluated using multi-reader-multi-case (MRMC) methodology where each reader read all three tracings.
False Positives: The MRMC Study evaluated the relative FP rate for SureCALL® and tocodynamometry. The results demonstrated that clinician judgment on individual deflections varied widely.
Summary: The three-way clinical study and the follow-up MRMC study demonstrate that the SureCALL® uterine EMG technology detects uterine contractions as well as conventional tocodynamometry. However, the technology infrequently presents low amplitude deflections that may appear to be contractions but do not correspond to uterine contractions. These deflections may represent electrical activity in the myometrium that is not sufficiently organized to cause the uterine smooth muscle to contract.

4. Indications for Use:
The SureCALL® EMG Labor Monitor® is a transabdominal electromyography (EMG) monitor intended to measure intrapartum uterine activity. It is intended for use on women who are at term (>36 completed weeks), in labor, with singleton pregnancies, using surface electrodes on the maternal abdomen. The device is intended for use by healthcare professionals in a clinical setting.

The SureCALL® EMG Labor Monitor® is a transabdominal electromyography monitor. The device consists of a Signal Conditioning Module specifically designed to collect. filter, and amplify the electromyographical (EMG) signal and a separate Control System to analyze, record, and display the EMG signal. In addition, the device records and displays the input from standard FDA-cleared maternal heart rate sensor, fetal, heart rate sensor, intrauterine pressure catheter and tocodynamometer transducer devices, along side the EMG signal traces.

The Control System consists of an off-the-shelf laptop computer with a LabVIEW based program designed to collect, record and display electrical signals in a meaningful and quantifiable format.
6. Summary of the technological characteristics of the device compared to predicate devices:
The difference from the predicate device is the type of input sensors. Predicate devices utilize strain gauges held in place with a belt. The SureCALL® EMG Labor Monitor utilizes paste-on Ag/AgCl electrodes.
The SureCALL® EMG monitors contractions through the noninvasive detection of uterine myoelectric activity recorded from the abdominal surface, while the Tocodynamometer monitors contraction through the detection of pressure changes on the abdominal surface. Both of these physiological signals have the same origin event, i.e. electrical activity by the uterus; therefore either one can be measured to detect the presence of contractions.
7. Testing:
Testing of the SureCALL® EMG Labor Monitor® included functional performance, electrical safety, and clinical studies as outlined in FDA Guidance Documents, regulations, and by FDA reviewers. The SureCALL® EMG Labor Monitor® has successfully completed all required testing.
8. Clinical Studies
The primary study supporting the effectiveness of the SureCALL® monitor involved

20 women at term, in labor, at three clinical sites. Each study subject was instrumented with three technologies for measuring uterine activity:
- (1) a tocodynamometer (toco) attached to the maternal abdomen
- (2) a set of abdominal surface electrodes for uterine electromyography (SureCALL®), and
- (3) an intrauterine pressure catheter (IUPC).
Using IUPC as the 'gold standard', this study methodology allowed a three-way comparison for evaluating how well the SureCALL® system performed vis-a-vis the toco technology.
After completion of this study, in a second study the three different monitor tracings were evaluated using multi-reader-multi-case (MRMC) methodology where each reader read all three tracings.
False Positives
When SureCALL® or tocodynamometry tracings exhibit a deflection above baseline that does not have a corresponding deflection on the gold standard IUPC, that deflection may be considered a false positive (FP). The MRMC Study evaluated the relative FP rate for SureCALL® and tocodynamometry. The results of this analysis demonstrated that clinician judgment on individual deflections varied so widely that it is unclear whether the comparison of the FP rate for SureCALL® versus toco in the MRMC Study is generalizable.
To illustrate how individual clinical judgment may vary, the following example displays a SureCALL® tracing with at least two discernable deflections above baseline which do not correspond to deflections on the IUPC tracing.
Image /page/2/Figure/10 description: The image shows two graphs, one labeled "SureCALL" and the other labeled "IUP". Both graphs show a cyclical pattern, with peaks and valleys. There are arrows pointing to specific points on the "SureCALL" graph. The graphs are printed on a grid-like background.
Figure 1: Aligned Tracings, SureCALL® and IUP
If most or all of the types of SureCALL® deflections in Figure 1 (above) are counted as contractions, then SureCALL® may display more FP contractions compared to tocodynamometry. This difference, however, is unlikely to have an adverse impact on clinical outcomes in full term laboring patients.
Summary
In summary, the three-way clinical study and the follow-up MRMC study demonstrate that the SureCALL® uterine EMG technology detects uterine contractions as well as conventional tocodynamometry. However, the technology infrequently presents low

amplitude deflections that may appear to be contractions but do not correspond to uterine contractions. These deflections may represent electrical activity in the myometrium that is not sufficiently organized to cause the uterine smooth muscle to contract.
9. Rx or OTC
The SureCALL® EMG Labor Monitor® is a Rx prescription device per 21 CFR Subpart D. The indication for use is for clinical settings only.
10. Conclusions:
Based on testing and comparison to the predicate devices, the SureCALL® EMG Labor Monitor® has the same intended use, and is substantially equivalent to the predicate devices. The device performs as intended and does not raise any new safety or effectiveness issues.
