The summary describes a device based on Vibration-Controlled Transient Elastography (VCTE™) technology using ultrasound to measure shear wave speed and estimate tissue stiffness and attenuation. There is no mention of AI, ML, or related concepts in the device description, intended use, or performance studies. The performance evaluation focuses on bias and precision compared to a predicate device, not on the performance of an AI/ML algorithm.
No
Explanation: The device is described as providing measurements and estimates of tissue stiffness and attenuation, which are explicitly stated to be used "as an aid to clinical management" or "as an aid to diagnosis and monitoring." It does not directly provide therapy or treatment.
Yes
The device provides measurements and estimates (shear wave speed, tissue stiffness, and ultrasound coefficient of attenuation) that are explicitly stated to be used "as an aid to diagnosis and monitoring of adult patients with liver disease." This direct mention of aiding diagnosis classifies it as a diagnostic device.
No
The device description explicitly states that the FibroScan® 230 system includes a smaller equipment unit (which includes the hand-held probes) in addition to the FibroScan® application. This equipment unit is a hardware component.
Based on the provided information, the FibroScan® 230 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use describes the device as providing measurements of shear wave speed, tissue stiffness, and ultrasound coefficient of attenuation in internal structures of the body (specifically the liver). These are physical measurements taken directly from the patient's body.
- Device Description: The device description explains that it uses ultrasound and mechanical vibration to measure properties within the liver.
- Lack of In Vitro Activity: An IVD device is designed to examine specimens derived from the human body (like blood, urine, tissue samples) in vitro (outside the body) to provide information about a physiological state, health, or disease. The FibroScan® 230 does not process or analyze such specimens. It directly interacts with the patient's liver.
Therefore, the FibroScan® 230 is a medical device used for non-invasive physical measurements in vivo (within the living body), not an IVD.

Device Description
FibroScan® System and its probes is an active non-implantable medical device using ultrasound and based on Vibration- Controlled Transient Elastography (VCTETM) technology. It is designed to perform non-invasive measurements of liver shear wave speed and estimate 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 focus of this submission is the new FibroScan® 230, which separates the FibroScan® System into two parts: a smaller equipment unit (which includes the hand-held probes) and the FibroScan® application, installed on the user's computer. The FibroScan® Application displays the user interface of the system and interacts with the equipment unit through a USB connection. The FibroScan® Application may also interact with the Echosens Cloud through an internet network. Only the FibroScan® 230 equipment and FibroScan® application are included in the FibroScan® 230 system while the Echosens cloud and the end-user computer are not part of the FibroScan® 230 medical device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The FibroScan® 230 effectiveness was evaluated in terms of its bias and precision in measuring liver shear wave speed (m/s) and CAP, using the S+, M+ and XL+ probes. Both a comparison with the predicates' documented performance (as presented in K203273) and a direct comparison of the measurement accuracy between the proposed and cleared systems were performed.
Direct comparison refers to testing the predicate and candidate device contemporaneously using the same probes, phantoms, and experimental setup, thereby controlling for environmental conditions (temperature, humidity), imperfections in the materials and manufacturing process leading to sample inhomogeneities, as well as the viscoelastic properties of the materials used to construct the phantoms which may lead to changes in their stiffness values.
The shear wave speed bias measurement and the precision measurement was evaluated and compared to the documented corresponding value reported for the predicate device. Results show that, for liver examination, the bias and precision measurements of the candidate FibroScan® 230 system and the predicate FibroScan® 530 Compact system documented similar performance. Specifically, the ranges of the bias values documented for the candidate are substantially equivalent to the ranges of the bias values documented for the predicate device (4.9% - 14.6% for the candidate and 0.5% - 12.6% for the precision values documented for the candidate are very similar to the ranges of the precision values documented for the predicate device.
Direct comparison of the CAP results, using dynamic testing (>200 measurements) on multiple spots demonstrated the range and mean values of CAP bias were substantially equivalent to the bias of the CAP in the candidate device (range of 1.4% - 11.1% for the candidate CAP dynamic testing and 1.8% – 10.1% for the predicate). In addition, the range and mean values of CAP precision values were equivalent to the precision of the CAP in the candidate device.
An additional direct comparison between the candidate and predicate devices showed that the bias values for the shear wave speed and CAP were shown to be comparable (under 5% difference) between FibroScan® 230 and FibroScan® 530 Compact. Therefore, the proposed systems have substantially equivalent effectiveness in measuring shear wave speed and CAP bias.
Furthermore, the stiffness and CAP measurement ranges, as well as the SmartDepth ranges, have been verified on the FibroScan® 230 system and are the predicate device.
In summary, the bias and the precision of the shear wave speed and the CAP measured by the FibroScan® 230 are within the same ranges as those of the predicate FibroScan® 530 Compact cleared in K203273 and, therefore, considered substantially equivalent.

Device Description
FibroScan® System and its probes is an active non-implantable medical device using ultrasound and based on Vibration- Controlled Transient Elastography (VCTE™) technology. It is designed to perform non-invasivemeasurements of liver shear wave speed and estimate 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 focus of this submission is the new FibroScan® 230, which separates the FibroScan® System into two parts: a smaller equipment unit (which includes the hand-held probes) and the FibroScan® application, installed on the user's computer. The FibroScan® Application displays the user interface of the system and interacts with the equipment unit through a USB connection. The FibroScan® Application may also interact with the Echosens Cloud through an internet network. Only the FibroScan® 230 equipment and FibroScan® application are included in the FibroScan® 230 system while the Echosens cloud and the end-user computer are not part of the FibroScan® 230 medical device.
Comparison of Technological Characteristics
The FibroScan® 230 system is substantially equivalent to the FibroScan® 530 Compact system cleared by 510(k) #K203273. Both systems provide 50Hz shear wave speed measurements and estimates of tissue stiffness in the liver using the S+, M+, and XL+ transducers. Additionally, both systems encompass a Controlled Attenuation Parameter (CAP) designed to estimate the ultrasound attenuation (forward and return paths) at the frequency of 3.5 MHz.
The FibroScan® 230 modification relates to its design configuration and therefore includes structural differences in system design software architecture and electronic architecture (e.g., no integrated touchscreen). The FibroScan® 230 system liver measurement is otherwise identical to the predicate FibroScan® 530 Compact system as related to the intended use and indications for use, same operating principle and materials, same S+, M+, and XL+ probes, emits the same energy, same examination procedure, acquires the same information, applies the same signal processing and imaging modes, displays the same information, performance measurements, and manufacturing process. Therefore, the design changes related to FibroScan® 230 do not impact the liver examination. Table 1 provides a detailed comparison of the candidate and predicate devices.
As with the predicate device, the CAP (previously called CAPc) and SmartDepth options are enabled with the 'SmartExam' capability. The SmartDepth automatically adapts the depth of the liver stiffness measurement (LSM) based on the anatomy of the patient and is available for M+ and XL+ probes while CAP is available for S+, M+, and XL+ probes. The LSM and CAP calculated with the SmartDepth capability uses the same algorithm as the predicate system.

Intended Use / Indications for Use
The FibroScan® 230 is intended to provide shear wave speed measurements and estimates of tissue stiffness as well as ultrasound coefficient of attenuation (CAP: Controlled Attenuation Parameter) in internal structures of the body. The shear wave speed and stiffness measurements may be used as an aid to clinical management of adult patients with liver disease.
The FibroScan® 230 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, and CAP may be used as an aid in the clinical management of pediatric patients with liver disease.
Performance Data
The FibroScan® 230 effectiveness was evaluated in terms of its bias and precision in measuring liver shear wave speed (m/s) and CAP, using the S+, M+ and XL+ probes. Both a comparison with the predicates' documented performance (as presented in K203273) and a direct comparison of the measurement accuracy between the proposed and cleared systems were performed.
Direct comparison refers to testing the predicate and candidate device contemporaneously using the same probes, phantoms, and experimental setup, thereby controlling for environmental conditions (temperature, humidity), imperfections in the materials and manufacturing process leading to sample inhomogeneities, as well as the viscoelastic properties of the materials used to construct the phantoms which may lead to changes in their stiffness values.
The shear wave speed bias measurement and the precision measurement was evaluated and compared to the documented corresponding value reported for the predicate device. Results show that, for liver examination, the bias and precision measurements of the candidate FibroScan® 230 system and the predicate FibroScan® 530 Compact system documented similar performance. Specifically, the ranges of the bias values documented for the candidate are substantially equivalent to the ranges of the bias values documented for the predicate device (4.9% - 14.6% for the candidate and 0.5% - 12.6% for the precision values documented for the candidate are very similar to the ranges of the precision values documented for the predicate device.
Direct comparison of the CAP results, using dynamic testing (>200 measurements) on multiple spots demonstrated the range and mean values of CAP bias were substantially equivalent to the bias of the CAP in the candidate device (range of 1.4% - 11.1% for the candidate CAP dynamic testing and 1.8% – 10.1% for the predicate). In addition, the range and mean values of CAP precision values were equivalent to the precision of the CAP in the candidate device.
7
An additional direct comparison between the candidate and predicate devices showed that the bias values for the shear wave speed and CAP were shown to be comparable (under 5% difference) between FibroScan® 230 and FibroScan® 530 Compact. Therefore, the proposed systems have substantially equivalent effectiveness in measuring shear wave speed and CAP bias.
Furthermore, the stiffness and CAP measurement ranges, as well as the SmartDepth ranges, have been verified on the FibroScan® 230 system and are the predicate device.
In summary, the bias and the precision of the shear wave speed and the CAP measured by the FibroScan® 230 are within the same ranges as those of the predicate FibroScan® 530 Compact cleared in K203273 and, therefore, considered substantially equivalent.
Clinical Data
No clinical data was required for this submission.
Substantial Equivalence Discussion
The FibroScan® 230 includes the same intended use and indications for use, uses the same operating principle and materials, emits the same energy and acquires the same information as the predicate FibroScan® 530 Compact device (K203273). The separation of the system unit from the FibroScan® application, installed on the user's computer, do not raise new or different questions of safety or efficacy.
The candidate device was demonstrated to be substantially equivalent to its predicate device FibroScan® 530 (K203273) based on the aforementioned verification and validation studies.
Conclusion
The conclusions drawn from the clinical and nonclinical information provided in this submission demonstrate that FibroScan® 230 is as safe, as effective, and performs as well as the legally marketed device predicate. The FibroScan® 230 raises no new or different issues of safety or effectiveness and is substantially equivalent to its predicate device.
