Management of pain associated with post-traumatic or post-operative conditions.

Device Story

Tone-A-Matic is a portable, micro-controller-operated powered muscle stimulator and TENS device. It generates pre-programmed electrical impulses (Russian, TENS, EMS modes) delivered via adhesive electrode pads to specific body areas. The device features an LCD screen for monitoring treatment mode, countdown timer, and battery status; intensity is adjusted via keypads. It is intended for clinical use by healthcare professionals to treat multiple body areas simultaneously. By delivering controlled electrical stimulation, the device aims to relax muscle spasms, prevent atrophy, improve circulation, re-educate muscles, maintain range of motion, and manage pain. It is powered by a 24 VDC adapter or rechargeable battery, allowing for mobility in clinical settings.

Clinical Evidence

Bench testing only. The submission relies on performance testing, including electrical safety and electromagnetic compatibility (IEC 60601-1, IEC 60601-1-2, IEC 60601-2-10, IEC 60601-1-11), software verification, and risk analysis (ISO 14971) to demonstrate substantial equivalence to the predicate device.

Technological Characteristics

Portable micro-controller-based stimulator; 24 VDC adapter or rechargeable battery power. Enclosure: ABS; Lead wires: PVC. Electrodes: 2"x2" self-adhesive. Output: 8 channels, synchronous. Waveforms: Square wave (Russian, TENS, EMS). Connectivity: Standalone. Sterilization: Not applicable (non-sterile). Software: Micro-controller firmware.

Indications for Use

Indicated for patients requiring muscle stimulation for spasm relaxation, disuse atrophy prevention, blood circulation improvement, muscle re-education, range of motion maintenance, or post-surgical venous thrombosis prevention; and for patients requiring TENS for symptomatic relief of chronic, intractable pain or management of post-traumatic/post-operative pain.

Regulatory Classification

Identification

An ultrasound and muscle stimulator for use in applying therapeutic deep heat for selected medical conditions is a device that applies to specific areas of the body ultrasonic energy at a frequency beyond 20 kilohertz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies. The device also passes electrical currents through the body area to stimulate or relax muscles.

### TRADITIONAL 510(K)

#### ANNEXURE 'VIII'

### INTENDED USE:

Tone-A-Matic is indicated to be used for

#### Russian and EMS for:

- Relaxation of muscle spasms
- Prevention or retardation of disuse atrophy .
- . Increase local blood circulation
- Muscle re-education .
- . Maintaining or increasing range of motion
- Immediate postsurgical stimulation of calf muscles to prevent venous thrombosis.

#### L TENS for:

- Symptomatic relief of chronic, intractable pain. .
- · Management of pain associated with post-traumatic or post-operative conditions.

### SUBSTANTIAL EQUIVALENCE:

The electrical stimulation provided by the Tone-A-Matic device is similar to that of Predicate Device Winstim. The electrical pulses transmitted in different modes are restricted in amplitude and duration to values consistent with that of the predicate device quoted above in electrical parameter comparisons. User safety has been taken into account while designing the Tone-A-Matic device.

The differences that exist between these devices are insignificant in the terms of safety or effectiveness.

{7}------------------------------------------------

#### TRADITIONAL 510(K)

## NON-CLINICAL TESTS PERFORMED:

Tone-A-Matic complies with international standards for electrical safety and electromagnetic compatibility. Compliance to applicable voluntary standards includes IEC 60601-1. Ed3.0, IEC 60601-1-2, IEC 60601-2-10,IEC 60601-1-11 and ISO 14971: 2007. Comprehensive risk analysis has been carried out for the device with regards to safety and effectiveness. Addition to the compliance of voluntary standards, the software verification has been carried out according to the FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.

#### CONCLUSION:

The electrical stimulation provided by the Tone-A-Matic device is similar to that of Predicate Device Winstim.

The Tone-A-Matic has same intended use and similar technological characteristics as its FDA cleared predicate devices. Moreover the verification and validation tests contained in this submission demonstrate that the differences in the Tone-A-Matic still maintain the same safety and effectiveness as that of the cleared predicate. In other words, those enqineering differences do not: (1) affect the intended use or (2) alter the fundamental scientific technology of the device.

Safety concerns regarding proper use of electrodes and electrode pads placement have been fully addressed by making the user conscious of the proper placement of electrodes and proper operations of the device through detail in the User's Instruction Manual.
