Device Story
Biospace Body Composition Analyzers (InBody770, 570, S10, 230) are impedance plethysmographs used to estimate body composition. Device applies multi-frequency electrical currents to body via 8-point tactile electrodes; measures impedance, resistance, and reactance. Lean tissue (high water/electrolyte content) conducts current better than fat/bone. Device transforms electrical response data into estimates of body water (ICW, ECW, TBW), skeletal muscle mass, body fat, and metabolic rates. Used in clinical settings by healthcare professionals to manage fat/lean tissue balance. Output provided as numerical values and graphs; assists clinicians in assessing patient body composition and fluid compartmentalization. Benefits include non-invasive, rapid assessment of body composition parameters.
Clinical Evidence
Clinical testing conducted on approximately 80 patients, aged 6 to mid-60s, both genders. Study compared new models (InBody 770, 570, S10, 230) against predicate devices. Results demonstrated excellent correlation with coefficients nearly 1.00 for all four units. Bench testing included electromagnetic safety (IEC 60601-1, IEC 60601-1-2) and software validation.
Technological Characteristics
Impedance plethysmograph using multi-frequency bioelectrical impedance analysis (BIA). Employs 4-pole, 8-point tactile electrode measurement system. Operates at various frequencies (1kHz to 1000kHz depending on model). Measures resistance, reactance, and phase angle. Connectivity and software details not specified beyond general software validation. Power source: AC 100-240V, 50/60Hz. Dimensions and weight vary by model.
Indications for Use
Indicated for healthy subjects, ages 3 to 99, for body composition analysis including measurement of body water, muscle mass, fat mass, and metabolic rates via bioelectrical impedance analysis.
Regulatory Classification

- 4. Description: Impedance plethysmographic devices are used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs. Multi-frequency and segmental bioelectrical impedance analysis can estimate the distribution of body water (total body water; intra-cellular water), and can correlate with fluid compartmentalization. Assuming that body lean mass is hydrated in a constant and uniform manner; bioelectrical impedance analysis can be used to estimate body lean mass and fat mass.
These devices are impedance plethysmograph body composition analyzers. These devices
{4}------------------------------------------------
determine body composition parameters based on bioelectrical impedance analysis (BIA). BIA relies on the differing behavior of biological tissues in response to an applied electrical current. Lean tissue is generally highly conductive because it contains large amounts of bound water and electrolytes, while fat tissue and bone are relatively poor conductors. By analyzing the response to electrical signals, BIA thereby permits differentiation of lean tissue, fat, and water and, in some instances, derivation of related body composition parameters. The total impedance resulting from BIA incorporates both resistance and capacitance components. Impedance plethysmographic devices are used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs. Multi-frequency and segmental bioelectrical impedance analysis can estimate the distribution of body water (total body water; intra-cellular water; extra-cellular water), and can correlate with fluid compartmentalization. Assuming that body lean mass is hydrated in a constant and uniform manner; bioelectrical impedance analysis can be used to estimate body lean mass and fat mass. Body composition analysis results may be of value to health care professionals in their management of the relative balance and levels of fat and lean tissue

- Discussion of Non-Clinical Testing: Electromagnetic and Safety Testing was conducted 7. to IEC 60601-1 and IEC 60601-1-2. Software validation was conducted. Literature was compiled and reviewed.
- 8. Discussion of Clinical Testing: We conducted clinical testing on each model and compared the results to a predicate. Approximately 80 patients aged 6 to mid 60's, both males and females, were tested. The correlation coefficients for all four new units were very nearly 1.00 showing excellent correlation.
- 9. Conclusion: As compared to our predicate devices (our own brand) these new models have very similar technological characteristics and performed comparably to our predicates. The same scientific principles are used to produce the measurements. We therefore conclude that our new models are substantially equivalent to our predicate previously cleared. The new devices are therefore substantially equivalent to our predicates.
