Intended Use

The X4 System is intended for prescription use in the home, healthcare facility, or clinical research environment to acquire, record, transmit and display physiological signals from adult patients. The X4 System acquires, records, transmits and displays electroencephalogram (EEG), electrooculogram (EOG), electrocardiogram (ECG), and/or electromyogram (EMG), accelerometer, acoustical and photoplethesmographic signals. The X4 system only acquires and displays physiological signals, no claims are being made for analysis of the acquired signals with respect to the accuracy, precision and reliability.

Device Story

X4 System is a physiological signal acquisition device for adult patients; used in home, clinical, or research settings. Inputs include EEG, EOG, ECG, EMG, acoustic, PPG, and 3-D accelerometer data. Device features head-worn sensors; records data to internal memory or transmits wirelessly to a PC for display. Operated by patients (self-application) or technicians. Firmware monitors signal quality to ensure proper sensor application. Output is raw physiological data in European Data Format (EDF) for review by healthcare providers via third-party software. Device does not perform automated analysis; provides visual signal inspection to assist clinicians in diagnostic workflows. Benefits include simplified home-based physiological monitoring.

Clinical Evidence

Clinical testing conducted to evaluate home-use feasibility. Study demonstrated that >90% of overnight recordings were interpretable. Subjects successfully applied the device and resolved audio alarms without difficulty, confirming usability in the home environment.

Technological Characteristics

Physiological signal acquisition system; EEG, EOG, ECG, EMG, PPG, acoustic, and 3-D accelerometer sensors. Wireless connectivity for real-time display; internal memory for data storage. Compliant with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, IEC 60601-2-26, and ISO 10993-1. Firmware-based signal quality monitoring.

Indications for Use

Indicated for adult patients in home, healthcare facility, or clinical research settings for the acquisition, recording, transmission, and display of EEG, EOG, ECG, EMG, accelerometer, acoustic, and PPG signals.

# DEVICE DESCRIPTION:

The X4 system is used for configurable acquisition of physiological signals. Model X4-E provides for acquisition of three channels of electroencephalography (EEG) and one photoplethesmographic (PPG) signal from a head strip, with an optional channel connected to two sensors via a dual-lead connector with twice the gain. Model X4-M provides four channels of EEG with the dual-lead connector providing the input for reference sensors. Both models measure sound via an acoustic microphone, and movement and position measured via a 3-D accelerometer. The device is designed so it can be affixed by the patient and to record data. Alternatively, a technician can affix the device and display the signals via a wireless connection during acquisition. The X4 system firmware monitors signal quality to ensure that the sensors are properly applied and that high quality signals are being acquired.

The X4 software provides a means to: a) initiate a study and track patient information, b) acquire and save signals to the memory of the device, c) acquire and wirelessly transmit signals from the device, d) upload data saved in the memory of the device to a PC, and e) visually inspect the signal quality.

The acquired signals are saved in a universal data format (European Data Format – EDF) that is intended to be analyzed with third party software, including Advanced Brain Monitoring's Sleep Profile Software (K120450).

## INTENDED USE:

The X4 System is intended for prescription use in the home, healthcare facility, or clinical research environment to acquire, record, transmit and display physiological signals from adult patients. The X4 System acquires, records, transmits and displays electroencephalogram (EEG), electrooculogram (EOG), electrocardiogram (ECG), and/or electromyogram (EMG), accelerometer, acoustical and photoplethesmographic signals. The X4 system only acquires and displays physiological signals, no claims are being made for analysis of the acquired signals with respect to the accuracy, precision and reliability.

# TECHNOLOGY:

The X4 System uses the same fundamental technology as the ARES Model 610 for most features including the electrophysiological (EEG), photoplethesmographic (PPG) and actigraphy signals. Acquisition of the electrocardiograph signal requires minor modification to the band pass filters and is equivalent to the Compumedics Somte. Wireless acquisition of the physiological signals is equivalent to the Infinite Biomedical Technologies 1200 two-channel EEG system. The technologies used in the X4 are used in the same manner as the predicate products and do not raise new questions of safety and effectiveness.

# DETERMINATION OF SUBSTANTIAL EQUIVALENCE:

### SUMMARY OF NON-CLINICAL TESTS:

Support for the substantial equivalence of the X4 System was provided as a result of risk management and testing which included electrical and biological safety, performance and software tests. This testing includes conformity to FDA recognized consensus standards and voluntary standards as follows:

| Standard Number | Standard Title |
|-----------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| IEC 60601-1-1:1988+A1:<br>1991+A2: 1995 | Medical Electrical Equipment - Part 1: General requirements for safety |
| IEC 60601-1-2: 2007 | Medical Electrical Equipment Part 1-2: Collateral standard: Electromagnetic<br>compatibility - requirements and tests |
| ISO 10993-1: 2009 | Biological evaluation of medical devices Part 1 |
| IEC 60601-1-11: 2010 | Medical electrical equipment - Part 1-11: General requirements for basic<br>safety and essential performance - Collateral Standard: Requirements for<br>medical electrical equipment and medical electrical systems used in the<br>home healthcare environment |
| IEC 60601-2-26:2002 | Particular requirements for the safety of electroencephalographs |

Additional verification and validation testing confirmed:

- All features of the X4 System were compliant with the system level requirements. .
- Signals acquired with the X4 System provide similar information as compared to the predicate . device that would allow a physician to interpret the signals.

#### SUMMARY OF CLINICAL TESTS:

The X4 has been the subject of clinical testing to demonstrate it can be used by patients in the home. The results support that over 90% of studies recorded overnight with the X4 are interpretable and behave as expected. The X4 instructions were applied without difficulty, allowing all subjects to properly apply the device so that it remained in the proper position and allowing any problems that triggered an audio alarm to be properly resolved.

#### CONCLUSION:

Advanced Brain Monitoring considers the X4 System to be as safe, as effective, and substantially equivalent to the predicate devices.
