Intended Use

The V12 PRO is indicated for the temporary relief of minor muscle aches and pains and for temporary increase in circulation to the treated areas in people who are in good health. The V12 PRO simulates kneading and stroking of tissues by using an inflatable garment.

Device Story

V12 PRO is an intermittent pneumatic compression system for home, clinic, or athlete training use. It consists of an air compressor unit, hoses, and inflatable garments (arm, leg, trouser, jacket) with 12 compression chambers. The device operates by sequentially inflating and deflating chambers from the limb end toward the body center to simulate kneading and stroking. A microprocessor-controlled system manages pressure and timing based on sensor feedback. Users operate the device via a membrane keypad and 3.2" LCD screen, selecting therapy times (15-60 minutes) and pressure levels (15-80 mmHg). By increasing local circulation and providing massage-like compression, the device aims to relieve minor muscle aches and pains. It is intended for over-the-counter use by healthy individuals.

Clinical Evidence

No clinical data. Evidence consists of bench testing, including biocompatibility (cytotoxicity, irritation, sensitization per ISO 10993), electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and software verification/validation. A pressure distribution comparison test demonstrated that V12 PRO and the predicate exhibit similar compression pressure curves.

Technological Characteristics

Powered inflatable tube massager; 12-chamber sequential gradient compression. Materials: Nylon with polyurethane laminate (garments), molded ABS (housing). Power: 110-230V 50/60Hz. Interface: Membrane keypad, 3.2" LCD. Connectivity: Standalone. Software: Microprocessor-controlled firmware. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, ISO 10993.

### 3. PREDICATE DEVICE

The V12 PRO is substantially equivalent to the following predicate device:

- Ballancer 505 System, Model 1201 AC (K150269) -
### 4. DEVICE DESCRIPTION

V12 PRO utilizes a software-controlled air compression pump, which sequentially inflates and deflates cells within a compression garment (sleeve) that is put around a limb. V12 PRO consists of an air pump, air pressure sensor, and sleeves working together as one unit. The air pump is connected to the dedicated sleeves via a series of hoses; each sleeve has twelve (12) compression chambers. The compression massage direction is from limb end to body center. By inflating the air chambers sequentially and then deflating as one cycle, the pressure can be adjusted to avoid any discomfort to the patient. The sleeve works under the action of sensor and microprocessor. Software controls the timing and pressure reflected by the sensor, cycling airflow into and out of the sleeves to compress body.

{4}------------------------------------------------

The V12 PRO consist of an air compressor unit with a control system, an inflatable garment (arms, legs, trouser and jacket), silicon air tubing with proprietary connectors for connecting the device to the appliance, and a power cord.

The user interface on the V12 PRO is a Membrane Keypad with dome switches. The settings are shown on a 3.2″ LCD Screen.

# 5. INDICATIONS FOR USE

The V12 PRO is indicated for the temporary relief of minor muscle aches and pains and for temporary increase in circulation to the treated areas in people who are in good health. The V12 PRO simulates kneading and stroking of tissues by using an inflatable garment.

# 6. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

Intermittent pneumatic compression is the technological principle for both the subject and the predicate device. The subject and the predicate devices are based on the following same technological elements:

- Electronically controlled Air Pump with inflatable compression garments -(arm, leg, jacket and Hip garment), which conducts a sequential compression of the patient's limbs.
The following technological differences exist between the subject and the predicate devices:

- -While V12 PRO uses a turning dial to set the pressure, the predicate uses push buttons for this function.

# 7. PERFORMANCE DATA

All tests were performed with the reference device VariLymph 12 Pro (V12 PRO).

There are no performance standards under the Federal Food, Drug and Cosmetic Act, for a compressible limb sleeve device. The testing included various performance tests and software validation tests, designed to ensure that the device met all its functional specifications. Tests have been performed to ensure the device complies with industry and safety standards.

The following performance data were provided in support of the substantial equivalence determination:

#### Biocompatibility testing

The biocompatibility evaluation for the V12 PRO device was conducted in accordance with the FDA "Use of International Standards ISO-10993, #Biological Evaluation of Medical Devices Part 1: Evaluation and Testing,"" May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices -Part 1: Evaluation and Testing within a Risk Management Process," as recognized by FDA. The battery of testing included the following tests:

- Cytotoxicity i
- Irritation
- Sensitization

The intended use of the product involves contact with the intact skin for a period of less than 24 hours. To evaluate the biocompatibility of the product, a cytotoxicity test as per ISO 10993-5:2009 and skin irritation and sensitization test as per ISO 10993-10:2013 were therefore considered sufficient. Any knowledge to be gained from further biocompatibility testing with this product would not justify the unnecessarily high level of harm to experimental animals involved. As per ISO 10993-1:2009 such tests were not performed. The type and scope of the tests performed complies with the specifications as per ISO 10993-1:2009.

### Electrical Safety and Electrical Compatibility (EMC)

Electrical safety and EMC testing were conducted on the V12 PRO. The system complies with the IEC 60601-1. A justification how all the applicable statutory or regulatory criteria of the EN 60601-1 are met through recognition of IEC 60601-1 was provided.

{9}------------------------------------------------

IEC 60601-1-2:2014 standard for EMC and IEC 60601-1-11 Medical electrical equipment: General requirements for basic safety and essential performance was tested as well.

### Software Verification and Validation Testing

Software verification and validation testing were conducted, and documentation was provided as recommended by FDA´s Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submission for Software Contained in Medical Devices."

# Pressure Distribution Comparison Test

The purpose of the test was to find out if the V12 PRO has a pressure distribution comparable to that of the predicate (Ballancer 505 System) to ensure that the device is as safe and effective as a legally market device.

Summary: Based on the tests it can be concluded that there are a few differences between the pressure curves but both products show a similar compression pressure cure in longitudinal direction. From this result it can be also concluded that both devices have the same technological characteristics. The V12 PRO was found to have a safety and effectiveness profile that is similar to the predicate device.

# 8. CONCLUSION

The conclusion drawn from the above Performance Testing and comparison to predicate device is that the V12 PRO is substantially equivalent in safety and efficacy to the predicate device listed above.

The non-clinical data support the safety of the device and the hardware and software verification und validation demonstrate that the V12 PRO should perform as intended in the specified use conditions. The data demonstrates that the V12 PRO device performs comparably to the predicate device that is currently marketed for the same intended use (temporary relief of minor muscle aches and pains and for temporary increase in circulation to the treated areas in people who are in good health). V12 PRO device uses sequential inflation and deflation of cells within compression sleeves put around a limb. Inflation/Deflation, pressures, pressure distribution and sequences are similar to those of the predicate device.
