The device measures or calculates the impedance, BMI(Body Mass Index), weight, and WHR(Waist to Hip Ratio) of the user. This device is intended for use only in healthy subjects between the age of 7-89. ## Device Story Body composition analyzer using Bio-electrical Impedance Analysis (BIA); 8-electrode system placed on hands and feet. Device measures impedance, weight, and calculates body composition metrics (PBF, MBF, LBM, TBW, BMI, BMR, segmental LBM, ICW, ECW, ECW/TBW ratio, WHR) via experimentally derived algorithm. Powered by AC adapter. Used for healthy subjects aged 7-89. Output provided to user/clinician for health assessment. ## Clinical Evidence No clinical data. Bench testing only; device meets IEC 60601-1 and EN 60601-1-2 standards. Equivalence established via technical comparison of measurement parameters, frequencies, and electrode patterns to predicate. ## Technological Characteristics BIA method; 8-electrode configuration; AC adapter power; dimensions/form factor not specified. Software algorithm uses experimentally derived parameters for body composition calculation. Standards: IEC 60601-1, EN 60601-1-2. ## Regulatory Identification An impedance plethysmograph is a device used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs. ## Special Controls *Classification.* Class II (special controls). The device, when it is a body composition analyzer which is not intended to diagnose or treat any medical condition, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9. ## Predicate Devices - Body Composition Analyzer Models GAIA 359 PLUS and XBIA 500 ([K071884](/device/K071884.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

This device is intended for use only in healthy subjects between the age of 7-89. Technologic characteristics: Modified device ioi 353 has the same intended use and technology characteristics as predicate device GAIA 359 PLUS or XBIA 500. The differences in this submission don't raise new questions concerning either safety or effectiveness. Non-clinical and clinical tests: Modified device ioi 353 meets the requirements of IEC 60601-1, EN 60601-1-2 and in-house test criteria. The ioi 353 was not clinically tested because the ioi 353 measures/outputs/determines the same quantities, uses the same frequencies, and uses the same electrode pattern and number of electrodes as the GAIA 359 PLUS. Conclusions: Based on non-clinical tests, the modified device ioi 353 is as safe, as effective, and perform as well as the predicate device GAIA 359 PLUS or XBIA 500. Accordingly the modified devices are substantially equivalent to the predicate device. {2}------------------------------------------------ Image /page/2/Picture/0 description: The image shows the seal of the Department of Health & Human Services - USA.
