Device Description
LiverSmart is software that utilizes two existing FDA cleared devices, HepaFat-AI (K201039) and FerriSmart (K182218) and combines their respective results into a singular consolidated multiparametric 'LiverSmart' report. LiverSmart automatically sorts and sends magnetic resonance imaging (MRI) datasets to each of the existing HepaFat-AI and FerriSmart devices and then receives results from those devices to generate a summary report which combines the HepaFat-AI results (an estimate of the patient's volumetric liver fat fraction (VLFF), proton density fat fraction (PDFF), steatosis grade), and the FerriSmat result (an estimate of the patient's liver iron concentration (LIC)). To conduct analysis, the user simply uploads a single zipped folder containing HepaFat-AI and FerriSmart DICOM images, acquired in accordance with their respective acquisition protocols, to the LiverSmart software. No user input is required for the analysis thereby minimising the impact of human error. The LiverSmart software requires image input data that has been acquired in accordance with the existing and now well established HepaFat-AI (K201039) and FerriSmart (K182218) imaging protocols. LiverSmart has two new components that are in addition to the existing components of HepaFat-AI and FerriSmart, namely a: - (i) Data Preparation Module; and - (ii) Report Generation Module The rest of the components for LiverSmart are the existing components of the FDA cleared HepaFat-AI and FerriSmart devices, as follows: For HepaFat-AI: - (i) Magnetic Resonance Imaging Protocol - (ii) HepaFat-AI Analysis Software - (iii) Volumetric Liver Fat Fraction Measurement - (iv) Proton Density Fat Fraction Measurement - (v) Steatosis Grade Measurement For FerriSmart: - (i) Magnetic Resonance Imaging Protocol - (ii) FerriSmart Analysis Software - (iii) Liver Iron Concentration Measurement The above HepaFat-AI and FerriSmart components are the same as previously provided to the FDA as the time HepaFat-AI and FerriSmart regulatory clearances were sought (and subsequently obtained).
More Information

Yes
The summary explicitly states that the device utilizes "Convolutional neural networks for the image analysis," which is a type of artificial intelligence/machine learning. Furthermore, the predicate devices, HepaFat-AI and FerriSmart, are mentioned, and the name "HepaFat-AI" strongly suggests the use of AI in one of the underlying components.

No.
The device is described as software that measures and monitors liver conditions (iron concentration and fat assessment) and aids in diagnosis and monitoring, which are diagnostic and monitoring functions, not therapeutic ones.

Yes

The "Intended Use / Indications for Use" section explicitly states that LiverSmart is indicated to "measure liver iron concentration" and "assess the volumetric liver fat fraction, proton density fat fraction and steatosis grade." It also states that "When interpreted by a trained physician, the results can be used to... monitor liver iron burden," "aid in the identification and monitoring of non-transfusion-dependent thalassemia patients," "monitor liver fat content," and "aid in the assessment and screening of living donors for liver transplant." These are all diagnostic activities.

Yes

The device is described as "software that utilizes two existing FDA cleared devices" and its components are listed as software modules and existing software components from the predicate devices. There is no mention of new hardware being part of the LiverSmart device itself.

Based on the provided information, this device is NOT an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to examine specimens outside of the body.
  • LiverSmart's Function: LiverSmart analyzes Magnetic Resonance Imaging (MRI) data. MRI is an imaging technique that uses magnetic fields and radio waves to create detailed images of organs and tissues inside the body.
  • Input Data: The input data for LiverSmart is DICOM images acquired from MRI scans, not biological samples.
  • Analysis Method: LiverSmart processes and analyzes these images to provide measurements of liver iron concentration and liver fat. This is image analysis, not laboratory testing of biological specimens.

Therefore, LiverSmart falls under the category of medical imaging software rather than an in vitro diagnostic device.

No
The input explicitly states "Control Plan Authorized (PCCP) and relevant text: Not Found", meaning the letter does not contain the required language to answer "Yes" based on the Key Decision Rules.

Intended Use / Indications for Use

For Liver Iron Concentration:

  1. measure liver iron concentration in individuals with confirmed or suspected systemic iron overload;
  2. monitor liver iron burden in transfusion dependents and patients with sickle cell disease receiving blood transfusions:

SUMMARY OF CHANGE(S)

LiverSmart consists of two additional modules, over and above the FerriSmart and HepaFat-AI modules;

  • (i) the Data Preparation Module, and
  • (ii) the Report Generation Module.

PERFORMANCE PARAMETERS

No change from the predicates, FerriSmart (K182218) and HepaFat-AI (K201039).

SUMMARY OF DESIGN CONTROL ACTIVITIES

Hazard analysis has been performed and documented. Hazard analysis is included in this submission. The test methods used are the same as those documented in the previously cleared submissions of the predicate devices, FerriSmart (K182218) and HepaFat-AI (201039). A statement of conformity with design controls is included in this submission.

SAFETY

LiverSmart is designed and manufactured under the Quality System Regulations as outlined in 21 CFR § 820 and ISO 13485 Standards. LiverSmart is based upon the same technologies, operating principle, and software technology as the two predicate devices. Risk activities were conducted in concurrence with established medical device development standards and guidance.

TESTING

Risk analy sis and verification testing conducted are documented and included in this submission, which demonstrate that the performance requirements have been met.

SUBSTANTIAL EQUIVALENCE

Verification testing confirms that the data preparation module of LiverSmart detects anomalies in the sequence acquisition and reports the accurate error message. If an error is detected LiverSmart prevents further analysis. Additionally, LiverSmart yields identical results for VLFF, PDFF, steatosis grade, and LIC, when the same image datasets are analysed by HepaFat-AI and FerriSmart devices independently.

CONCLUSION

The special 510(k) premarket notification for LiverSmart contains adequate information and data to enable the FDA-CDRH to determine substantial equivalence to the predicate devices. Resonance Health believes that enough evidence has been presented in this dossier to conclude that LiverSmart is safe, effective and performs as well as two the predicates.
