Intended Use

The ZEUS 9.9 and VENUS 5.5 body composition analyzers are intended to estimate PBF(Percentage of Body Fat), MBF(Mass of Body Fat), LBM(Lean Body Mass), TBW(Total Body Water), BMI(Body Mass Index), BMR(Basic Metabolic Rate), Segmental LBM, ICW(Intra-Cellular Water), ECW(Extra-Cellular Water), and ratio of ECW/TBW using the BIA(Bio-electrical Impedance Analysis) method. The device measures or calculates the impedance, BMI(Body Mass Index), weight, and WHR(Waist to Hip Ratio) of the user. These devices are intended for use only in healthy subjects between the age of 7-89. The only difference between the ZEUS 9.9 and VENUS 5.5 is head part of main unit; that is, the head part of the ZEUS 9.9 has a key pad and touch screen while the head part of the VENUS 5.5 has only a touch screen.

Device Story

Compact, automatic impedance plethysmograph; measures body composition via BIA method. Inputs: user-provided personal data (height, weight, gender, age) and measured body impedance. Operation: tetra-polar electrodes contact hands and feet; device injects minute electric current (360 µA) to measure impedance across whole body and segments (arms, legs, trunk). Output: PBF, MBF, LBM, TBW, BMI, BMR, segmental LBM, ICW, ECW, ECW/TBW ratio, and WHR. Used in clinical or general settings; operated by user. ZEUS 9.9 features keypad and touch screen; VENUS 5.5 features touch screen only. Output provides quantitative body composition metrics to assist in health monitoring and assessment.

Clinical Evidence

Clinical comparison testing performed in healthy subjects (ages 7-89) comparing ZEUS 9.9 against BODYSTAT Quad Scan 4000 and TANITA BC-418. Results demonstrated no significant difference in performance between subject and predicate devices.

Technological Characteristics

Impedance plethysmograph; BIA method; tetra-polar electrode configuration (8 electrodes). AC line powered (110-120V, 50/60Hz). Compliance with IEC 60601-1, IEC 60601-1-2, and ISO 10993 standards.

Indications for Use

Indicated for healthy subjects aged 7-89 for estimation of body composition parameters including body fat, lean body mass, total body water, BMI, BMR, and segmental body water distribution using bioelectrical impedance analysis.

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.

Predicate Devices

• BODYSTAT Quad scan 4000 Body Composition Analyzer (K002835)
• TANITA Body Composition Analyzer BC-418 (K033157)

### Operation: The subject device employs a measurement algorithms which is called BIA method, to measure user's body composition.

ZEUS 9.9/VENUS 5.5 device's tetra-polar type electrode connect to human body and then send an minute electric current like 360 A human body and then ZEUS 9.9/VENUS 5.5 device can measure impedance of the human body.

ZEUS 9.9/VENUS 5.5 can measure body composition of user with personal data which already saved height, weight, gender, ages and new calculated body impedance.

Model ZEUS 9.9/VENUS 5.5 is AC line powered(AC 110~120V, 50/60Hz) Power:

- 5. INTENDED USES: The ZEUS 9.9 and VENUS 5.5 body composition analyzers are intended to estimate PBF(Percentage of Body Fat), MBF(Mass of Body Fat), LBM(Lean Body Mass), TBW(Total Body Water), BMI(Body Mass Index), BMR(Basic Metabolic Rate), Segmental LBM, ICW(Intra-Cellular Water), ECW(Extra-Cellular Water), and ratio of ECW/TBW using the BIA(Bio-electrical Impedance Analysis) method. The device measures or calculates the impedance, BMI(Body Mass Index), weight, and WHR(Waist to Hip Ratio) of the user. These devices are intended for use only in healthy subjects between the age of 7-89. The only difference between the ZEUS 9.9 and VENUS 5.5 is head part of main unit; that is, the head part of the ZEUS 9.9 has a key pad and touch screen while the head part of the VENUS 5.5 has only a touch screen.
#### 6. COMPARISON WITH PREDICATE DEVICE.

Models ZEUS 9.9/VENUS 5.5 of Jawon devices have been compared with BODYSTAT Quad Scan 4000 of BODYSTAT LTD and TANITA Body Composition Analyzer BC-418. The intended uses of Jawon devices and predicate devices are the same. Both of Jawon devices and predicate devices use BIA(Bio-electrical Impedance Analysis) method to estimate body composition parameters,

The differences between Jawon devices and predicate devices are as follows Measurement frequency is 50, 5, 100, 200kHz for BODYSTAT Quad Scan 4000, and 50kHz for Tanita BC-418 instead of 50, 1, 5, 250, 550, 1000kHz for Jawon devices. 4 electrodes are placed on hands and feet for BODYSTAT Quad Scan 4000 and 8 electrodes on hands and feet for Tanita BC-418 instead of 8 electrodes on hands and feet(or ankle) for Jawon devices.

- Impedance measurement site is whole body for BODYSTAT Qaud Scan 4000 and right arm, right leg, left arm, left leg and trunk for Tanita BC-418 instead of whole body, right arm, right leg, left arm, left leg and trunk for Jawon devices.
- Therefore, there is no difference in intended use and no technologic differences that raise new questions concerning either safety or effectiveness.
