Intended Use

The Liver Incytes System is intended to provide estimates of tissue stiffness generated from shear wave speed measurements (40-70 Hz) and coefficient of attenuation. The device is indicated to non-invasively determine liver tissue stiffness and attenuation. These are meant to be used in conjunction with other clinical indicators in order to assist in clinical management of patients with liver disease.

Device Story

Liver Incytes is a point-of-care ultrasound elastography system for clinics and hospitals. Operated by medical professionals, the system includes an activation unit placed under a supine patient to induce shear waves (40-70 Hz) in the liver and an ultrasound transducer placed on the patient's skin over the intercostal space. The device captures volumetric ultrasound scans during shear wave propagation. It calculates tissue stiffness from shear wave speed and estimates attenuation from the ultrasound signal. Output is provided to the clinician to assist in the management of patients with chronic liver disease, serving as an adjunct to other clinical indicators.

Clinical Evidence

No clinical trials were performed. Evidence consists of bench testing on phantoms with known elasticity and attenuation to validate accuracy and precision. A usability study was conducted with a small cohort of healthy volunteers (BMI 25-43 kg/m2) using novice users to confirm successful operation within the intended population.

Technological Characteristics

Ultrasound-based elastography and attenuation measurement system. Complies with ANSI AAMI 60601-1, IEC 60601-1-2, IEC 60601-1-6, IEC 62304, IEC 60601-2-37, IEC 62359, ISO 14971, ISTA 3A, and ISO 10993-1. Operates via shear wave induction (40-70 Hz) and volumetric ultrasound scanning.

Indications for Use

Indicated for patients with liver disease to non-invasively determine liver tissue stiffness and attenuation. Used in conjunction with other clinical indicators to assist in clinical management.

Regulatory Classification

# Predicate Device

Predicate Device: EchoSens FibroScan® (K160524) manufactured by EchoSens, Paris, France, and cleared on March 18, 2016.

Reference device: Magnetic Resonance Elastography (K140666) is used as the reference device for some performance testing.

# Device Description

Liver Incytes is a non-invasive ultrasound based device for measuring tissues stiffness and ultrasound attenuation in patients with chronic liver disease. The device uses ultrasound measurements of shear wave speed in the tissues to estimate stiffness. The attenuation is measured through the ultrasound signal itself.

The device is designed to be used at the point of care, in clinics and hospitals. The device is used by a medical profession, an employee of the clinic/hospital. The activation unit is placed under the patient, while lying supine on an exam bed. The activation unit vibrates causing shear waves within the liver of the patient. The ultrasound transducer is placed on the patient's skin, over the intercostal space, and is used to take volumetric scans of the liver while shear waves are occurring. From the scan data, the device calculates tissue stiffness and attenuation.

Above the words is a blue line, and above that is a series of blue and black vertical lines that resemble a sound wave. The logo is simple and modern, and the use of blue and black gives it a professional look.

# Intended Use/ Indication for Use

The Liver Incytes System is intended to provide estimates of tissue stiffness generated from shear wave speed measurements (40-70 Hz) and coefficient of attenuation. The device is indicated to noninvasively determine liver tissue stiffness and attenuation. These are meant to be used in conjunction with other clinical indicators in order to assist in clinical management of patients with liver disease.

# Substantial Equivalence

The candidate device has an equivalent intended use and indications for use as the predicate device. Further, it has the same operating principle.

The technology used in the candidate, predicate device and reference device is based on ultrasound to measure elastography and attenuation. The systems measure the same physical variables, tissue stiffness and ultrasound attenuation, and therefore the devices are substantially equivalent in their basic technology. The accuracy and precision of the device were found to be substantially equivalent to those of the predicate device and reference device (MRI Elastography). The new device does not raise any new issues of safety or effectiveness.

# Performance Data

The following non-clinical testing was performed and submitted:

- Electrical safety, electromagnetic interference and ultrasound
- The accuracy and precision of the device was tested and documented based on tests performed on phantoms with known elasticity and attenuation.
- . The proposed device was tested in a small cohort of healthy volunteers with several novice users. This usability study showed that the device could be used successfully on volunteers with Body Mass Index from 25 to 43 kg/m2, representing the intended patient population. The users who participated in this study were representative of the intended use population.

# Recognized Consensus Standards Used

Non-clinical testing to assure compliance with acoustic output, biocompatibility, cleaning and disinfection effectiveness as well as thermal, electromagnetic and mechanical safety were performed and the device was found to conform to applicable medical device safety standards. The system complies with the following standards:

| ANSI AAMI 60601-<br>1:2005/(R)2012 And<br>A1:2012 | Medical Electrical Equipment - Part 1: General Requirements For Basic<br>Safety And Essential Performance (IEC 60601-1:2005, MOD) |
