Intended Use

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

Device Story

SureCALL® Labor Monitor® measures uterine activity via transabdominal electromyography (EMG). System comprises Signal Conditioning Module (SCM) and Control System (laptop with LabVIEW software). SCM collects, filters, and amplifies EMG signals from Ag/AgCl surface electrodes on maternal abdomen; also passes signals from external FDA-cleared fetal heart rate sensors, intrauterine pressure catheters, and tocodynamometers. Control System records and displays EMG traces and auxiliary physiological data. Used in clinical settings by healthcare professionals. Output provides clinicians with quantifiable uterine activity data to assist in labor monitoring and clinical decision-making.

Clinical Evidence

Clinical comparative study and multi-reader study. Comparative study (n=not specified) showed 96% ICC for uterine contraction detection and >95% agreement between RMS and tocodynamometer (TOCO). Mean peak difference between RMS and TOCO was 0.99s (p=0.4901). Multi-reader study in preterm patients showed sensitivity 75.6%–90.1% and individual agreement of 0.964.

Technological Characteristics

Transabdominal EMG monitor. Components: Ag/AgCl surface electrodes, Signal Conditioning Module (filtering/amplification), Control System (laptop). Software: LabVIEW-based. Connectivity: Accepts inputs from external FDA-cleared fetal heart rate sensors, intrauterine pressure catheters, and tocodynamometers. Standalone system.

Indications for Use

Indicated for pregnant women at term (>36 weeks gestation) with singleton pregnancies for measurement of uterine activity via transabdominal EMG.

Regulatory Classification

Identification

An external uterine contraction monitor (i.e., the tokodynamometer) is a device used to monitor the progress of labor. It measures the duration, frequency, and relative pressure of uterine contractions with a transducer strapped to the maternal abdomen. This generic type of device may include an external pressure transducer, support straps, and other patient and equipment supports.

#### 3. Predicate Device:

The SureCALL® Labor Monitor® is substantially equivalent to other Uterine Contraction Monitors in the market such as the SureCALL™ EMG Labor Monitor [K090145].

{1}------------------------------------------------

#### 4. Intended Use Statement:

K130002 page 2 of 2

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

#### 5. Description of Device:

The SureCALL® Labor Monitor® is a transabdominal electromyography monitor. The device consists of a Signal Conditioning Module specifically designed to collect, filter, and amplify the electromyographic (EMG) signal and a separate Control System to analyze, record, and display the EMG signal. In addition, the device has the option to record and display the input from standard FDA-cleared fetal heart rate sensor, intrauterine pressure catheter, and maternal heart rate sensor or tocodynamometers transducer device, alongside the EMG signal traces. The Signal Conditioning Module contains electronic components designed to receive a physiological signal from a set of Ag/AgCI surface electrodes placed on the subject's abdomen and amplify and filter the signal. The optional fetal heart rate, intrauterine pressure catheter, and maternal heart rate or tocodynamometer's signals originating and collected from FDA-cleared devices pass through the Signal Conditioning Module without modification. 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 easily quantifiable format.

#### 6. Summary of the technological characteristics of the device compared to predicate device:

There is no change in device from the predicate SureCALL™ EMG Labor Monitor [K090145].

#### 7. Testing:

Non clinical testing:

No new non-clinical testing was done since the SureCALL ™ EMG Labor Monitor [K090145].

Clinical testing:

The new indications for use were substantiated by a comprehensive clinical study and a follow-up multi-reader study with the SureCALL® Labor Monitor® and the tocodynamometer.

Results from the clinical comparative study show that:

- 1. With regard to uterine contraction detection, between-patient variance is 5.65 and within-patient variance is 72.89 with ICC of 0.96, suggesting that 96% of the variance is due to within-patient correlation and 4% variance is due to device to device variation.
- 2. The bootstrap agreement estimates for TOCO vs. SureCALL® RMS show that there was above 95% agreement between RMS and TOCO devices.
- 3. Overall mean peak difference between RMS and TOCO is 0.99 seconds (SE = 1.41), which is not significantly different from 0 at a = 0.05 level (P = 0.4901)

{2}------------------------------------------------

K130002 pg 3 of 3

Results from the multi-reader study show that:

- 1. The sensitivity ranged from 75.6% to 90.1% and the extra SureCALL® event rate ranged from 3.30 to 6.12 per hour among the readers in preterm patient.
- 2. The estimated individual agreement was 0.964 (>0.8) in preterm patients.

#### 8. Rx or OTC

The SureCALL® Labor Monitor is an Rx prescription device per 21 CFR Subpart D. The indication for use is for clinical settings only.

#### 9. Conclusions:

Based on testing and comparison to the predicate devices, the SureCALL® Labor Monitor® has the same intended use, and is substantially equivalent to the predicate. The device performs as intended and does not raise any new safety or effectiveness issues.
