Intended Use

The Avalon CL Fetal & Maternal (F&M) Pod & Patch is a device indicated for use by healthcare professionals in a clinical setting for non-invasive monitoring of maternal heart rate (aHR), fetal heart rate (aFHR), and uterine activity (aToco) in women who are at >36 completed weeks, in labor, with singleton pregnancy, using surface electrodes on the maternal abdomen.

Device Story

Beltless, battery-powered maternal-fetal monitoring system; consists of single-use adhesive patch (electrodes) and reusable pod.

Pod converts signals to Short-Range Radio (SRR) data; transmits to Avalon CL Base Station; relays to Philips Fetal-Maternal (FM) monitor. Used by healthcare professionals in clinical settings. Provides real-time tracing of FHR, MHR, and uterine activity; assists clinicians in monitoring labor progress and fetal well-being. Benefits include non-invasive, wireless monitoring without belts.

Clinical Evidence

Bench testing only. Includes biocompatibility (ISO 10993-5, 10993-10), electrical safety (ANSI AAMI ES60601-1), EMC (IEC 60601-1-2), wireless coexistence (IEEE ANSI C63.27), and performance testing (impedance, noise level, signal transmission, peel-off force, and accuracy under various temperature conditions).

Technological Characteristics

System includes reusable pod and disposable adhesive patch. Sensing: passive monitoring of electrical signals via 5-electrode array. Connectivity: Short-Range Radio (SRR) 802.15.4. Power: Li-ion battery. Software: Firmware in pod; no software in patch. Sterilization: Not applicable (disposable patch, reusable pod cleaned/disinfected).

Indications for Use

Indicated for women >36 weeks gestation, in labor, with singleton pregnancy, for non-invasive monitoring of maternal heart rate, fetal heart rate, and uterine activity in clinical settings.

#### 4. Device Description [21CFR 807.92 (a) (4)]

The Avalon CL Fetal & Maternal (F&M) Pod and the Avalon CL Fetal & Maternal (F&M) Patch is a beltless battery-powered maternal-fetal monitoring system that non-invasively measures abdominal fetal heart rate (aFHR), abdominal uterine activity (aToco), and abdominal maternal heart rate (aHR).

The Avalon CL Fetal & Maternal (F&M) Pod & Patch is part of the Philips 'Avalon Cableless (CL) Solution' Family and consists of the following components:

- Avalon CL Fetal & Maternal (F&M) Patch (PN: 989803196341) .
- . Avalon CL Fetal & Maternal (F&M) Pod (PN: 866488)

The Avalon CL Fetal & Maternal (F&M) Patch is a single-use disposable adhesive electrode patch designed to be affixed to the maternal abdomen.

The Avalon CL Fetal & Maternal (F&M) Pod is a reusable device which, when connected to the Avalon CL Fetal & Maternal (F&M) Patch, picks up electrical signals and converts it to Short Range Radio (SRR).

The operating range is typically 'in-room', unless the subject device is used in conjunction with the Avalon CL Wide Range Pod (PN: 866487), an optional accessory.

The Avalon CL Fetal & Maternal Pod communicates the data measurement values to the Avalon CL Base Station using Short-Range Radio (SRR). The Avalon CL Base Station in turn relays the information to the connected Philips Fetal-Maternal (FM) Monitor (i.e., FM20, FM30, FM40, and FM50).

The Avalon CL Fetal & Maternal Pod's software release version is D.05.23.

The Avalon CL Fetal & Maternal Pod utilizes identical software infrastructure and radio from the cleared Philips IntelliVue CL Pods (K101600) - NiBP and SpO2 devices. The IntelliVue CL

Pods have a similar purpose and are used in similar environments as the Avalon Pod.

The Avalon CL F&M Patch does not have software in a medical device (SiMD). No software resides in the Avalon CL Fetal & Maternal Patch.

#### 5. Indications for Use as required per 21 CFR 807.92(a)(5)

The Avalon CL Fetal & Maternal (F&M) Pod & Patch is a device indicated for use by healthcare professionals in a clinical setting for non-invasive monitoring of maternal heart rate (aHR), fetal heart rate (aFHR), and uterine activity (aToco) in women who are at >36 completed weeks, in labor, with singleton pregnancy, using surface electrodes on the maternal abdomen.

The subject and predicate devices have the same intended use, i.e., measuring FHR, MHR, and UA. The subject and predicate devices have the similar design, technology, and FHR output. They have different power sources, wireless technology, data interfaces, patch shelf-life, pod use-life and number of charging ports for pods. However, these differences do not raise different questions of safety and effectiveness.

# Non-Clinical Tests

- 1. Sterilization and Shelf Life
Sterilization is not applicable to the Avalon CL F&M Pod &Patch. The subject device is not designed to be sterilized or sterilizable.

The Avalon CL F&M Patch is a single-use, single-patient device and is disposed of upon removal or completion of treatment. The Avalon CL F&M Pod is a reusable device that has been verified and validated (V&V) for cleaning and disinfection.

- 2. Biocompatibility
The patient contacting components of the subject device met the acceptance criteria as defined in the test requirements. Tests were conducted based on contact and duration, as outlined in ISO 10993-1.

- . Cytotoxicity (ISO 10993-5)
- Sensitization (ISO 10993-10) ●
- Irritation (ISO 10993-10) ●

#### 3. Software/Firmware & Cybersecurity/Interoperability

The GE proprietary algorithm converts the Avalon CL Fetal & Maternal (F&M) Patch's electrical signals and converts it to usable signals to the Avalon CL F&M Pod. The pod relays the numerical results (aFHR, aHR, and aToco) to the cleared Avalon CL Base Station (K140535) using the SRR Radio Transceiver & Antenna. The IEEE 802.15.4 SRR interface board contains an on-board, integrated transceiver and antenna.

The Avalon CL Fetal & Maternal Pod utilizes identical software infrastructure and radio from the cleared Intelli Vue CL Pods (K101600) - NiBP and SpO2 devices. The Intelli Vue CL Pods have a similar purpose and are used in similar environments. Additionally, the SRR technology is cleared under Philips Avalon CTS Cordless Fetal Transducer System (K023931) and Avalon CL Base Station (K140535).

Verification and Validation (V&V) testing has been conducted to ensure the safety, performance, interoperability, and effectiveness of the subject device.

Software documentation was provided in accordance with FDA guidance document "Content of Premarket Submissions for Device Software Functions (fda.gov)" issued June, 2023.

The sponsor also provided cybersecurity documentation for the subject device per the 2023 FDA guidance "Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions (fda.gov)".

- 4. EMC, Wireless, Electrical, Mechanical and Thermal Safety
The subject devices met the acceptance criteria as defined in the test requirements per the standards listed above and 2022 FDA guidance "Electromagnetic Compatibility (EMC) of Medical Devices (fda.gov)".

- 5. Performance Bench
The subject devices met the acceptance criteria as defined in the test requirements. The following performance tests were conducted for the subject device:

- Inspection of the labelling and pouch sealing (Novii Patch) ●
- Impedance/tensile strength/pull-off force/noise level/conductivity/offset ● voltage/defibrillation overload for newly manufactured and aged (12 month) patches. (Novii Patch and Avalon Patch)
- . In vivo testing: integrity, detachment/reattachment, and performance (impedance, noise level, MHR, conductivity) after shower and usage (8 hours/32 hours) for the patch (Novii Patch).
- Peel-off force of each electrode and central sticker (Novii Patch and Avalon patch).
- MHR/FHR/UA accuracy after stored in room (23℃), high (32℃) and low (2-8℃) ● temperature (Novii Patch).
- Signal transmission continuity (Avalon Pod and patch).

#### 8. Conclusions

The non-clinical testing discussed above demonstrates that the Avalon CL Fetal & Maternal (F&M) Pod and Avalon Fetal & Maternal (F&M) Patch (Subject Device) is as safe and effective as the predicate device.
