No
The description focuses on the physical mechanism of vibration and ultrasound tracking, and there is no mention of AI or ML in the text.
No
The device is described as an aid to diagnosis and monitoring, and it provides measurements (shear wave speed, stiffness, and attenuation) rather than directly treating a condition.
Yes
The device is intended to provide measurements (shear wave speed, tissue stiffness, and attenuation coefficient) that may be used "as an aid to diagnosis and monitoring of adult patients with liver disease" and "as an aid to clinical management of pediatric patients with liver disease." The phrase "aid to diagnosis" directly indicates a diagnostic function.
No
The device description explicitly states that the FibroScan® system consists of a "system unit and a hand-held probe" and describes the physical mechanism of the probe (mechanical vibrator, ultrasound). This indicates the device includes significant hardware components beyond just software.
Based on the provided information, the FibroScan® Family of Products is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is for "noninvasive measurement in the liver" and provides "shear wave speed measurements and estimates of tissue stiffness as well as 3.5 MHz ultrasound coefficient of attenuation (CAP)". These are physical measurements taken directly from the body.
- Device Description: The description details a system that uses "Vibration-Controlled Transient Elastography (VCTE™) technology" and "Ultrasound" to track and measure physical properties within the liver.
- Lack of Biological Sample Analysis: IVD devices are designed to examine specimens derived from the human body (like blood, urine, tissue samples) to provide information about a person's health. The FibroScan® does not analyze biological samples; it interacts directly with the body to take measurements.
The device is a medical device that uses physical principles (vibration and ultrasound) to assess the physical properties of the liver, which can then be used as an aid in diagnosis and monitoring. This falls under the category of a non-invasive diagnostic imaging or measurement device, not an IVD.

Device Description
FibroScan® system consists of a system unit and a hand-held probe. It is based on Vibration-Controlled Transient Elastography (VCTE™) technology, and is designed to perform non-invasive measurements of liver shear wave speed and estimates of tissue stiffness. The probe containing a mechanical vibrator produces low-amplitude elastic waves that travel through the skin and intercostal space into the liver. Ultrasound is used to track the shear (elastic) wave, measure its speed and provide estimated stiffness. The results are displayed on the system unit.
The focus of this submission is the addition of the S+ probe to models FibroScan® 530 Compact and FibroScan® 430 Mini+. The S+ probe addresses a smaller anatomic size of pediatric patients, while using the same principle of operation, intended use and methodology (i.e. application to patient, signal measurement, processing and display), design, materials, manufacturing and testing processes as the previously cleared M+ and XL+ probes. In addition, the S+ probe developed for the 530 Compact and 430 Mini+ models is similar to the S+ probe cleared for the FibroScan® 502 Touch model of the FibroScan® Family of Products.

(a)
Identification. An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
Classification. Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

Predicate Device
This submission claims substantial equivalence to a combination of two previously cleared devices:
-
- Echosens's FibroScan® Family of Products (#K173034) cleared on November 14, 2017; and
-
- Echosens's FibroScan® System (#K150239) cleared on September 1, 2015.
Device Description
FibroScan® system consists of a system unit and a hand-held probe. It is based on Vibration-Controlled Transient Elastography (VCTE™) technology, and is designed to perform non-invasive measurements of liver shear wave speed and estimates of tissue stiffness. The probe containing a mechanical vibrator produces low-amplitude elastic waves that travel through the skin and intercostal space into the liver. Ultrasound is used to track the shear (elastic) wave, measure its speed and provide estimated stiffness. The results are displayed on the system unit.
The focus of this submission is the addition of the S+ probe to models FibroScan® 530 Compact and FibroScan® 430 Mini+. The S+ probe addresses a smaller anatomic size of pediatric patients, while using the same principle of operation, intended use and methodology (i.e. application to patient, signal measurement, processing and display), design, materials, manufacturing and testing processes as the previously cleared M+ and XL+ probes. In addition, the S+ probe developed for the 530 Compact and 430 Mini+ models is similar to the S+ probe cleared for the FibroScan® 502 Touch model of the FibroScan® Family of Products.

The shear wave speed and stiffness, and CAP may be used as an aid to diagnosis and monitoring of adult patients with liver disease, as part of an overall assessment of the liver.
Shear wave speed and stiffness may be used as an aid to clinical management of pediatric patients with liver disease.
Comparison of Technological Characteristics
The addition of the S+ probe applies to models 530 Compact and 430 Mini+ of the FibroScan® family of products. The S+ probe was previously cleared for the 502 Touch model, following the premarket notification process (#K150239). The FibroScan® Family of Products (Models: 502 Touch, 530 Compact, and 430 Mini+) is otherwise identical to the predicate FibroScan® Family of Products (#K173034) as related to the indications for use, operating principles, M+ and XL+ probes, materials, examination procedure, imaging capabilities, information processing, performance measurements, and manufacturing process.

Substantial Equivalence Discussion
The modified FibroScan® Family of Products (Models: 502 Touch, 530 Compact, and 430 Mini+) has the same intended use and indications for use, uses the same operating principle and materials, incorporates the same basic design, emits the same energy and acquires the same information as the predicate device (#K173034). In addition, the S+ probe has the same operating principle and materials, incorporates the same basic design, emits the same energy and acquires the same information as the S+ probe cleared in the predicate device (#K150239).
The S+ probe underwent hardware and software verification tests with the FibroScan® 530 Compact and FibroScan® 430 Mini+ systems to ensure that the candidate device raises no new or different issues of safety and effectiveness.
In summary, the FibroScan® Family of Products (Models: 502 Touch, 530 Compact, and 430 Mini+) is substantially equivalent to the predicate devices.

| Indications for Use | The FibroScan® Family of products (Models: 502 Touch, 530 Compact and 430 Mini+) is
intended to provide 50Hz shear wave speed measurements and estimates of tissue
stiffness as well as 3.5 MHz ultrasound coefficient of attenuation (CAP: Controlled
Attenuation Parameter) in internal structures of the body.
FibroScan® Family of products (Models: 502 Touch, 530 Compact and 430 Mini+) is
indicated for non-invasive measurement in the liver of 50 Hz shear wave speed and estimates
of stiffness as well as determining a 3.5 MHz ultrasound coefficient of attenuation (CAP:
Controlled Attenuation Parameter). The shear wave speed and stiffness, and CAP may be
used as an aid to diagnosis and monitoring of adult patients with liver disease, as part of an
overall assessment of the liver.
Shear wave speed and stiffness may be used as an aid in the clinical management of
pediatric patients with liver disease. | | |
