Intended Use

The EUM100Pro (Electro Uterine Monitor) is a transabdominal electromyography (EMG) monitor intended to non-invasively measure intrapartum uterine activity and fetal heart rate (FHR). The EUM100Pro acquires the signal from surface EMG electrodes placed on the patient abdomen. The EUM100Pro is intended for use on women (>36 completed weeks of gestation) in labor, with singleton pregnancies. The EUM100Pro is intended for use by healthcare professionals in a clinical setting.

Device Story

EUM100Pro is a transabdominal electromyography (EMG) monitor for intrapartum use. It acquires electrical signals via surface electrodes placed on the maternal abdomen; processes signals to measure uterine activity and fetal heart rate (FHR); and displays data as graphs. Used in clinical settings by trained medical personnel. Output provides real-time monitoring of uterine contractions and FHR, similar to traditional toco-dynamometer/Doppler monitors, to assist clinicians in labor management. Device is built around an EN 60950 certified computer and transmits data via RS232 protocol.

Clinical Evidence

Prospective comparative clinical study (n=33) in women at term during active labor. Compared EUM100Pro, Doppler (GE Corometrics 170), and gold-standard fetal scalp electrode (FSE). Results: EUM100Pro mean positive percent agreement (PPA) 98.5% (95% CI: 98.5-99.6%) vs Doppler 96% (95% CI: 95-98.2%). Mean RMS error (Bland-Altman) 1.47 bpm for EUM vs 4.42 bpm for Doppler. Mean delta from FSE 0.009 for EUM vs 0.232 for Doppler. Data demonstrates non-inferiority and higher similarity to FSE than Doppler.

Technological Characteristics

Transabdominal EMG sensing via surface electrodes. Mains power with isolation transformer. Graphical display. RS232 data transmission. Software-based FHR feature. Safety standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-40. Disposable surface electrodes (K990356).

Indications for Use

Indicated for women >36 weeks gestation in labor with singleton pregnancies. Contraindicated for patients with implanted electronic devices, open wounds, irritated skin, or silver allergies.

### 510(k) Summary Page 3 of 5 4-Aug-15

#### Substantial Equivalence Discussion

The EUM 100Pro is viewed as substantially equivalent to the predicate devices because:

#### Indications –

- The EUM 100Pro is indicated for as a transabdominal electromyography (EMG) monitor ● intended to measure fetal heart rate and intrapartum uterine activity.
- Discussion This is identical to the predicate K101801 Monica AN24. ●

#### Patient Population -

- It is intended for use on women who are (>36 completed weeks), in labor, with singleton ● pregnancies, using surface electrodes on the maternal abdomen
- . Discussion - The patient population is identical to the predicate - K101801 - Monica AN24.

#### Environment of Use -

- For use in clinical settings by trained medical personnel ●
- Discussion The environments of use and personal are identical to the predicate -. K101801 - Monica AN24.

#### Technology -

- The use of transabdominal electromyography (EMG) signals to sense fetal heart rate (FHR) and uterine activity via an array of surface electrodes placed on the maternal abdomen.
- Discussion - This technology is identical to the predicate - K101801 - Monica AN24

#### Non-clinical Testing Summary -

For the fetal heart rate (FHR) feature there is no bench testing, we performed comparative clinical testing vs. the predicates.

#### Biocompatibility of Materials -

- The materials in contact with the patient are the EMG electrodes which are off-the-shelf (K990356).
- Discussion The EMG electrodes have been cleared for the intended use under ● K990356 and in the reference device - K131889 - OB Tools EUM 100Pro.

#### Electrical, EMC, EMI testing -

- The proposed change to add the FHR feature was software only and there was no change ● in the electrical design of the reference device EUM 100Pro (K131889).
- . Discussion - The proposed device is identical to the reference device - K131189 OB Tools EUM 100Pro.

#### 510(k) Summary Page 4 of 5 4-Aug-15

#### Clinical Testing Summary -

We performed a comparative clinical study that was to show non-inferiority of the EUM100Pro with Fetal Heart Rate (FHR) as compared to the GE Corometrics Series 170 (K991905) and a fetal scalp electrode.

A clinical study was completed in order to show the non-inferiority of the EUM100Pro in monitoring fetal heart rate compared to Doppler based Fetal Monitor.

Thirty three women at term, during active labor. were enrolled; each subject enrolled was instrumented with three technologies for measuring fetal heart rate (FHR) as follows:

- EUM100Pro Test device ●
- Scalp electrode connected to Philips HP 50 XM Gold standard .
- GE/Corometrics 170 Doppler ultrasound cardiograph reference device ●

This study methodology allows comparison of the performance of EUM100Pro vs. Doppler as compared to the Scalp electrode gold standard.

#### Summary of Results

- There are significant differences in the PPA; the mean positive percent of agreement for . EUM was 98.5% 95%CI [98.5%-99.6%] compared with 96% 95%CI [95%-98.2%] for Doppler, demonstrating non-inferior results of the EUM as compared to Doppler in terms of percent of interpretable FHR.
- The mean RMS error from Bland Altman was 1.47 for EUM compared with 4.42 bpm ● for Doppler indicating that EUM is more similar to gold standard fetal Scalp electrode measurement compared to Doppler.
- The mean delta from Scalp is 0.009 95%CI [0.007-0.015] for EUM compared with 0.232 . 95%CI [0.227-0.256] for Doppler indicating that EUM is more similar to gold standard fetal Scalp electrode measurement compared to Doppler.

#### Discussion of Differences

A review of the differences for the proposed EUM 100Pro with the FHR feature as compared to the predicates and reference devices shows that there are no differences in indications for use, patient population, environments of use, design, technology and performance that would raises any new safety or effectiveness concerns.
