Intended Use

The Transtek Body Fat Analyzer measure weight and uses bioelectrical impedance analysis (BIA) technology to estimate body fat, total body water percentage, muscle mass, and bone mass in generally healthy adults 18 years of age or older. It is intended for use in the home/domestic setting only.

Device Story

Device is a body composition analyzer/scale for home use. Inputs: electrical current passed through body via BIA technology. Principle: measures resistance (impedance) of fat tissue vs. muscle/fluid to estimate body composition metrics. Outputs: weight, body fat, total body water, muscle mass, bone mass displayed on LCD. Includes Bluetooth module for wireless data transmission to external receiving devices. Operated by patient self-use. Data transmission is an independent add-on function; device functions as a conventional scale and analyzer regardless of wireless status. Benefits: provides users with health and fitness tracking data.

Clinical Evidence

Bench testing only. Performance tests, risk management, and design verification were conducted to demonstrate that the addition of wireless communication does not raise new safety or effectiveness questions.

Technological Characteristics

BIA technology; electrical current sensing. Bluetooth module for wireless connectivity. LCD display. Form factor: body composition scale. Standards: IEC60601-1 (electrical safety), IEC60601-1-2 (EMC), ISO14971 (risk management), FCC Part 15 (EMI).

Indications for Use

Indicated for generally healthy adults 18+ to estimate body fat, total body water, muscle mass, and bone mass, and to measure weight. Contraindicated for individuals with pacemakers or other internal medical devices.

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.

#### 5. Device Description

Transtek Body Fat Analyzer uses BIA (Bioelectrical Impedance Analysis) technology which passes an electrical current through the body to estimate body far mass, total body water, muscle mass and bone mass. The electrical current is low and may not be felt. The current passes freely through the fluids contained in muscle tissue, but encounters difficulty/resistance when it passes through fat tissue. This

# TRANSTEK

resistance of the fat tissue to the current is termed 'Bioelectrical Impedance', and is accurately measured by Transtek Body Fat Analyzer (GBF-1251-B, BF-1256-B, and GBF-1257-B).

This method simultaneously calculates personal body water, muscle mass, and bone mass, giving a more accurate reading of overall health and fitness. As well as being an analyzer, this device can be used as a conventional weight scale.

The Transtek Body Fat Analyzer embeds a Bluetooth (BT) module that allows it to connect to nearby BT receiving end. The LCD of device displays results. And once measurement is over, the device will start transmission data by BT. Thus users can receive, and display/storage, measurement data of Transtek Body Fat Analyzer unit through their end devices that embedded BT module.

#### 6. Intended Use of Device

The Transtek Body Fat Analyzer measure weight and uses bioelectrical impedance analysis (BIA) technology to estimate body fat, total body water percentage, muscle mass, and bone mass in generally healthy adults 18 years of age or older. It is intended for use in the home/domestic setting only.

#### 7. Design Control Activities and Performance Tests Summary

Design control activities for this modification have been implemented and performance tests of modified devices have been done. These performance tests, risk management, and design verification tests provide demonstration that the differences do not raise any new questions of safety and effectiveness.

Proposed Body Fat Analyzer conforms to (including, but not limited to) the following standards:

IEC60601-1-2, Electromagnetic compatibility

IEC60601-1, Electrical safety

ISO14971, Risk management to medical devices

FCC Part 15, EMI tests of FCC Radiation & RF rules and regulations

#### 8. Summary of Substantial Equivalence

8. I Differences between proposed device and the predicate device

The only significant function difference between the two devices is that the modified device add-on a wireless data communication, what user option, which can transmit measurement results to receiving end equipment.

More modification details are described in this submission.

8.2 Discussion

The Transtek Body Fat Analyzer has identical indication for use, fundamental scientific technology, energy type, and similar performance specifications, dimensional specifications, software/firmware, functions, labeling to the predicate device.

Section 6 - 510(k) Summary

{2}------------------------------------------------

# TRANSTEK

The only function difference between proposed device and the predicate device is that the modified device provides user an optional wireless data transmission. It is an add-on function that is entirely independent to the body compositions analyzer function. Regardless of wireless connection status, the analyzer normal works to carry out a bioelectrical impedance analysis and display its results.

Thus the wireless data transmission function does not affect the safety and effectiveness of the body analyzer function.

#### 9. Conclusions

The Transtek Body Fat Analyzer (GBF-1251-B, BF-1255-B, BF-1256-B, and GBF-1257-B) is substantially equivalent to the predicate device, GBF-950-D, by having the identical indications for use, identical fundamental scientific technologies, and an add-on function which does not impact the safety and effectiveness of the device.
