Intended Use

ArteVu is intended to noninvasively and continuously measure a patient’s blood pressure and pulse rate, which are derived from the pulse pressure waveform using the scientific method of pulse waveform decomposition, for use on adult patients aged between 50 and 86 years who are resting in a supine or similarly reclined position. ArteVu is calibrated using an ISO 81060-2 compliant sphygmomanometer. All parameters derived by ArteVu are shown on a compatible remote display monitor (RDDS) via wired transmission. The device is intended for use by clinicians or other properly trained medical personnel in professional healthcare facilities.

Device Story

ArteVu is a continuous noninvasive blood pressure (CNBP) monitoring system for professional healthcare use. It utilizes a disposable Finger Clip with a tactile sensor to capture pulse pressure waveforms at the fingertip. The device employs pulse waveform decomposition to derive blood pressure and pulse rate. Initial calibration is performed using an ISO 81060-2 compliant sphygmomanometer. Data is transmitted via wire to a remote display monitor (RDDS) and updated every two seconds. The system includes technical and physiological alarms. Unlike the predicate, which uses an oscillometric cuff requiring constant coupling pressure, ArteVu’s tactile sensor clip minimizes occlusion risk by requiring only secure placement. Clinicians use the real-time output to monitor hemodynamic status and identify abnormal conditions, facilitating timely clinical intervention.

Clinical Evidence

Clinical study conducted in Taiwan with 109 subjects recruited from operating rooms and intensive care units. Study design adhered to ISO 81060-2 acceptance criteria, with additional elements from IEEE 1708, ISO 81060-3, ISO 80601-2-61, and IEC 60601-2-27. Results demonstrated safety and effectiveness comparable to the CareTaker4 predicate. No adverse effects related to the device or study interventions were reported.

Technological Characteristics

Noninvasive blood pressure monitor; tactile sensor in disposable Finger Clip; passive electronic components; wired connectivity to remote display. Complies with ISO 10993 (biocompatibility), IEC 60601-1 (safety), IEC 60601-1-2 (EMC), ISO 81060-2 (calibration), IEEE 1708, ISO 81060-3, ISO 80601-2-61, and IEC 60601-2-27.

Indications for Use

Indicated for adult patients aged 50-86 years, resting in a supine or reclined position, requiring continuous noninvasive blood pressure and pulse rate monitoring in professional healthcare settings.

Regulatory Classification

Identification

A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body.

86 years who are resting in a supine or similarly reclined position.

ArteVu is calibrated using an ISO 81060-2 compliant sphygmomanometer. All parameters derived by ArteVu are shown on a compatible remote display monitor (RDDS) via wired transmission. The device is intended for use by clinicians or other properly trained medical personnel in professional healthcare facilities.

## Indications for Use Comparison
21 CFR 807.92(a)(5)

The subject ArteVu device has the same intended use as the predicate CareTaker4 System (K163255). They are both intended to noninvasively and continuously measure a patient's blood pressure and pulse rate, which are derived from the pulse pressure waveform using the scientific method of pulse waveform decomposition for use on adult patients at rest. Both devices include calibration, analysis, display, and alarms and are intended for use by clinicians or other properly trained medical personnel.

## Technological Comparison
21 CFR 807.92(a)(6)

The subject ArteVu device is similar to the predicate CareTaker4 device. Both devices utilize an analysis of pulse decomposition derived from piezoresistive inputs to quantify key hemodynamic parameters, including blood pressure. Both are calibrated using an ISO 81060-2 compliant blood pressure device, and all parameters are displayed on a monitor via wired transmission. The blood pressure and pulse measurement ranges are similar between the two devices. Both devices are intended for continuous monitoring and consist of a finger-contact mechanism. However, CareTaker4 uses an oscillometric cuff on a digit, which requires constant coupling pressure. In contrast, ArteVu uses a Finger Clip with a tactile sensor, which only requires the clip to be securely and comfortably placed on the digit without applying additional pressure. This design minimizes the risk of occluding blood flow to the monitored digit during extended use, as it does not require more pressure than necessary to keep the Finger Clip in place. Additionally, while the CareTaker4 does not contain any electrical components in the finger cuff, ArteVu incorporates passive electronic components inside the Finger Clip.

The different technological characteristics of the subject ArteVu system do not raise different questions of safety and effectiveness.

## Non-Clinical and/or Clinical Tests Summary & Conclusions
21 CFR 807.92(b)

To establish substantial equivalence to the CareTaker4, ArteVu adheres to the same nonclinical testing standards and meets all the essential performance requirements outlined in those standards. The test results demonstrate that ArteVu and CareTaker4 exhibit comparable levels of safety and effectiveness, ensuring compliance with regulatory benchmarks. Please refer to the eSTAR attachment titled "12.1_Bench Testing Summary" for additional information.

ArteVu's safety and effectiveness have been validated through a clinical study conducted in Taiwan involving 109 subjects. To establish substantial equivalence to the predicate device, CareTaker4, the study design adhered to the acceptance criteria of ISO 81060-2, which was also utilized in the clinical evaluation of CareTaker4. Moreover, to ensure compliance with state-of-the-art standards, the clinical study incorporated elements from IEEE 1708, ISO 81060-3, ISO 80601-2-61, and IEC 60601-2-27.

The study population included subjects recruited from operating rooms and intensive care units. The clinical data demonstrated that ArteVu achieves comparable safety and effectiveness to CareTaker4, supporting the determination of substantial equivalence.

Based on the results of the nonclinical and clinical tests, ArteVu has been demonstrated to be as safe, as effective, and to perform as well as or better than the predicate device, CareTaker4. The nonclinical tests, conducted in accordance with FDA-recognized consensus standards such as ISO 10993, IEC 60601-1, and IEC 60601-1-2, confirmed ArteVu's compliance with essential performance and safety requirements.

The clinical study, conducted with 109 subjects, further validated ArteVu's safety and effectiveness. The study adhered to ISO 81060-2 standards for substantial equivalence evaluation and incorporated elements of IEEE 1708, ISO 81060-3, ISO 80601-2-61, and IEC 60601-2-27, ensuring compliance with state-of-the-art guidelines. The study demonstrated that ArteVu achieves comparable levels of safety and effectiveness to the predicate device, CareTaker4, with adverse effects reported being unrelated to the device or study interventions.

In conclusion, the cumulative evidence supports the determination that the performance of ArteVu is substantially equivalent to the legally marketed CareTaker4 device in terms of safety and effectiveness.
