Intended Use

The device is a noninvasive bioimpeadance analyzer used to estimate body fat percentage in home use. The device is for normal, healthy person only, and the applicable age range is 20 to 80 years old.

The device is to be used in the ENVIRONMENT of room temperature & normal environment condition.

Device Description

AVITA BF1(Vitalio) Body Fat Analyzer is a hand-held, non-sterile, reusable Body Fat Analyzer intended for estimation of the body fat of percentage in the home.

AI/ML Overview

This 510(k) summary describes the AVITA BF1 (Vitalio) Body Fat Analyzer, which is a hand-held, non-sterile, reusable device intended for estimating body fat percentage in the home.

Here's an analysis of the provided information regarding acceptance criteria and the supporting study:

1. Table of Acceptance Criteria and Reported Device Performance:

The provided document does not explicitly state numerical acceptance criteria (e.g., a specific percentage of agreement, a required correlation coefficient, or a defined accuracy margin). Instead, it states the overall conclusion of the study's performance.

Acceptance Criteria (Implied)Reported Device Performance
Clinical RepeatabilityStatistically and clinically acceptable in all age/weight/height groups.

2. Sample Size Used for the Test Set and Data Provenance:

The document does not specify the sample size for the comparison study.
The data provenance is not explicitly stated as retrospective or prospective, nor does it mention the country of origin of the data. It merely mentions "A comparison study with device that use DEXA(Dual energy X-ray absorptiometry) technology was performed".

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

The document does not mention using experts to establish ground truth for the test set.

4. Adjudication Method for the Test Set:

The document does not mention any adjudication method.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

This is not applicable to this device. The AVITA BF1 (Vitalio) Body Fat Analyzer is a standalone device for estimating body fat percentage, not an AI-assisted diagnostic tool that would involve human readers.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done:

Yes, a standalone performance assessment was conducted. The "comparison study with device that use DEXA(Dual energy X-ray absorptiometry) technology" directly evaluates the performance of the AVITA BF1 device (algorithm only, as there's no human interpretation component) against a reference standard.

7. The Type of Ground Truth Used:

The ground truth used for the test set was obtained from a DEXA (Dual energy X-ray absorptiometry) device. DEXA is considered a highly accurate method for measuring body composition, including body fat percentage, and is often used as a reference standard in such studies.

8. The Sample Size for the Training Set:

The document does not provide any information about a training set or its sample size. This suggests the device might be based on established bioimpedance principles and a pre-existing algorithm, rather than being a newly developed AI model requiring a separate training phase described in this submission.

9. How the Ground Truth for the Training Set was Established:

As no training set is mentioned, information on how its ground truth was established is not provided.

2.0Device Name:AVITA BF 1 BODY FAT ANALYZERModels
3.0Classification:Class II
4.0Predicate Device:AVITA BF1(Vitalio) Body Fat Analyzer has similar general designwith Omron HBF-306 Body Fat Aalyzer(K011652) marketed byOmron Healthcare INC.
5.0Device Description:AVITA BF1(Vitalio) Body Fat Analyzer is a hand-held, non-sterile,reusable Body Fat Analyzer intended for estimation of the body fatof percentage in the home.
6.0Intended Use:The AVITA Body Fat Analyzer is intended for estimation of thebody fat of percentage in the home.
7.0PerformanceSummary:In terms of operating specification, Safety & EMC requirements, thedevice conforms to applicable standards included IEC 60601-1 andIEC 60601-1-2 requirements. Moreover, A comparison study withdevice that use DEXA(Dual energy X-ray absorptiometry)technology was performed to validate the performance of the AVITABF1(Vitalio) Body Fat Analyzer. Subjects were grouped as male/female, ages. The comparison study demonstrated that the clinicalrepeatability of AVITA BF1(Vitalio) Body Fat Analyzer isstatistically and clinically acceptable in all age/weight/height groups.

8. Conclusions:

The AVTA BF1(Vitalio) Body Fat Analyzer have the same intended use and similar technological characteristics as Omron HBF-306 Body Fat Aalyzer( K011652 )marketed by Omron Healthcare INC.. Moreover, bench testing contained in this submission and clinical testing supplied demonstrate that any differences in their technological characteristics do not raise and new questions of safety or effectiveness. Thus, the AViTA BF1(Vitalio) Body Fat Analyzer is substantially equivalent to the predicate devices.

Dear Ms. Reich:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
