Indications for Use
PeriCALM Patterns is intended for use to provide additional secondary information as an adjunct to qualified clinical decision-making during antepartum or intrapartum obstetrical monitoring at ≥32 weeks gestation for annotation and summary of the fetal heart rate recording for baseline, accelerations and decelerations and the uterine pressure recording for contractions. WARNING: Evaluation of FHR during labor and patient management decisions should not be based solely on PeriCALM Patterns annotations or summaries and should include inspection of the fetal monitor tracing and consideration of all pertinent clinical information.
Device Story
Software device for obstetrical care; processes fetal heart rate (FHR) and uterine activity data from external electronic fetal/maternal monitors. Uses Long and Short-Term Memory (LSTM) neural networks to detect, label, and measure FHR features (accelerations, decelerations, baseline) and uterine contractions. Operates in networked or standalone workstation environments. Provides clinicians with summarized measurements in 15 or 30-minute intervals; displays long-term compressed tracing views. Clinicians use output as secondary information to support decision-making; can modify or delete annotations. Benefits include automated pattern recognition and summary to assist in monitoring fetal status during labor or antepartum periods.
Clinical Evidence
Retrospective multi-reader/multi-case study; 70 subjects (30 preterm, 40 term). Compared PeriCALM Patterns 3.0 performance against a panel of 3 expert 'Truthers' and clinician readers. Endpoints included sensitivity, specificity, and PPV for accelerations/decelerations, and Bland-Altman analysis for baseline measurements (bias, LoA). Non-inferiority margins set at 15% for detection and 10% for baseline. Device met all 16 co-primary endpoints, demonstrating non-inferiority to clinician readers across both term and preterm subgroups.
Technological Characteristics
Software-based pattern recognition system. Utilizes signal processing and LSTM neural networks. Inputs: FHR (min 4 samples/sec) and uterine activity (min 1 sample/sec) from external monitors. Connectivity: Networked or standalone workstation. Software evaluated per 2023 FDA guidance for software functions and cybersecurity.
Indications for Use
Indicated for use in pregnant patients at ≥32 weeks gestation during antepartum or intrapartum obstetrical monitoring. Used as an adjunct to clinical decision-making for annotation and summary of fetal heart rate and uterine pressure recordings.

Dear Candace Alva:
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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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 your device in the Federal Register.

| Device Description | |
PeriCALM Patterns 3.0 is a software device to be used with fetal/maternal monitoring systems. The subject device is a software algorithm to detect, label and measure features (accelerations, decelerations, baseline, and contractions) in electronic fetal monitoring (EFM) records. PeriCALM Patterns 3.0 uses fetal monitor data imported through an interface with an external source or with a third-party clinical information system. PeriCALM Patterns can function in a networked environment or as a standalone workstation.
The subject device includes present-day Long and Short-Term Memory (LSTM) neural networks to identify segments of a fetal heart rate tracing corresponding to accelerations, decelerations, baseline as well as uninterpretable segments where is missing tracing. Contraction detection is achieved using the same processes as the predicate device.

The indications for use of PeriCALM Patterns 3.0 are similar to the predicate device and the subject and predicate device have the same intended use - as an adjunct to clinical decision making during antepartum, or intrapartum monitoring. The subject device has an extended gestational age from > 32 weeks, compared to the predicate device which has a gestational age from ≥ 36 weeks. This difference in gestational age does not raise different questions of safety and effectiveness.
The technological differences between the subject and predicate device include the addition of neural network interference (combined accel-decel-baseline + non-interpretable detection), different time intervals of analysis, and differences in the managements of non-interpretable segments for a missing trace. These differences do not raise different questions of safety and effectiveness as compared to the predicate device.

# Summary of Clinical Performance Testing
A retrospective study with multi-reader/multi-case technique was used to determine if the performance of PeriCALM Patterns 3.0 is not inferior to that of a set of qualified and experienced Obstetrician Gynecologists called the Clinician Readers. The predicate device was cleared for use in gestational ages of ≥36 weeks comparing to Ground Truth and Clinician Readers. The same approach was taken for this study, comparing PeriCALM Patterns 3.0 to Ground Truth and Clinician Readers for two gestational age subgroups: ≥36 weeks (term) and 32-35 weeks (pre-term). The ground truth for this study is established by a panel of 3 experts, called the "Truthers". To resolve the inter-observer variation, a majority opinion approach was used. The results of the comparison of the subject device to ground truth is to be non-inferior to the results of the comparison of Readers to ground truth.
A total of 70 subjects (30 preterm and 40 term), with one tracing per subject, were used in the study. Tracings were obtained from hospitals using a variety of fetal monitor models and manufacturers including Corometrics 170, 250 series by GE HealthCare, Avalon FM50 and FM40 by Philips Medical, and S1 from Neoventa and included both antepartum and intrapartum recordings. The tracings were selected from pregnancies with gestational ages from 32 weeks to term, covering a wide range of operating and clinical conditions with respect to maternal BMI, delivery modes, fetal birth weights, hospital types, Apgar scores and antepartum or intrapartum usage.
The study included sixteen (16) co-primary endpoints with different acceptance criteria for noninferiority. Twelve (12) co-primary endpoints pertained to accelerations and decelerations for both gestational groups (i.e., Term and Preterm) and included performance metrics (Sensitivity (Se), Specificity (Sp), Positive Predictive Value (PPV)) of the subject device compared to those of the Readers. Remaining four co-primary endpoints focused on the FHR baseline measurements and were based on Bland-Altman analyses to determine bias, the mean difference between two methods and the Limits of Agreement (LoA) which include 95% of the differences between the two measurement methods. Inferiority margin of 15% for acceleration and deceleration detection and 10% for baseline level was used. The acceptance criteria for 95% CI of Bias for the subject device was set to threshold of ≤ 5 bpm.
PeriCALM Patterns 3.0 passed all acceptance criteria on performance testing regarding pattern detection.
# Conclusion
The performance data described above demonstrate that the PeriCALM Patterns 3.0 is as safe and effective as the PeriCALM Patterns (K040788) and supports a determination of substantial equivalence.
