• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 870.2770
• Device Class: Class 2
• Attributes: Pediatric

Intended Use

A body composition analyzer that measures body weight and impedance and estimates total and segmental body fat percent, body mass index (BMI), fat mass, fat-free mass, regional muscle mass, basal metabolic rate, and total body water using BIA (bioelectrical impedance analysis) in healthy children (7-17 years old) and healthy adults.

Device Story

Computer-operated body composition analyzer; utilizes segmental bioelectrical impedance analysis (BIA) to determine body weight, body fat percentage, and regional muscle mass. Inputs: electrical impedance measurements via scale electrodes. Transformation: BIA technology calculates body composition metrics. Outputs: body weight, body fat %, BMI, fat mass, fat-free mass, regional muscle mass, BMR, and total body water. Used in clinical settings; operated by healthcare professionals. Output provides quantitative data to assist in assessing patient body composition and metabolic status.

Clinical Evidence

No clinical data provided. Substantial equivalence based on comparison of BIA methodology and performance characteristics to predicate device.

Technological Characteristics

Segmental BIA technology; computer-operated scale form factor. Measures impedance to estimate body composition. No specific materials or software architecture details provided.

Indications for Use

Indicated for healthy children (7-17 years) and healthy adults to measure body weight and impedance to estimate body fat, BMI, fat mass, fat-free mass, regional muscle mass, BMR, and total body water.

Regulatory Classification

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.

# 510(k) SUMMARY, continued

This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR §807.92

Side by side comparisons of the TANITA BC-418, Segmental Body Composition Analyzer to the predicate device Body Fat Analyzer Professional Model TBF-410 clearly demonstrate that the applicant device is substantially equivalent to the legally marketed device.

Based on the results of using the previously approved BIA methodology with our whole body BIA, it was concluded that the TANITA BC-418, Segmental Body Composition Analyzer performs as well as the predicate device and therefore have proven its safety and efficacy.
