Indications for Use

Indicated for patients requiring muscle stimulation, relaxation, or contraction; treatment of muscle spasms; prevention of disuse atrophy; muscle re-education; range of motion maintenance; venous thrombosis prevention; and pain management (chronic, intractable, post-traumatic, post-operative). Also indicated for therapeutic deep heat and topical heating for conditions including adhesive capsulitis, bursitis, myositis, soft tissue injuries, scar tissue, and arthritis-related stiffness.

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.

## 4. Product Description

The DermaWave 5000 Combi Max System is comprised of the following main components:

- A system console including software and control electronics. .
- A control and display panel. .
- · Delivery device accessories including patient cables and electrodes, ultrasound cables, soundheads, and infrared heating accessories.

#### 5. Indications for Use

The DermaWave 5000 Combi Max System and the delivery accessories that are used with them are indicated for use in the following:

Stimulation, relaxing, and/or repeatedly contracting muscles by passing electrical currents through electrodes contacting the affected body area in the medical specialties of physical medicine, general and plastic surgery and neurology and/or for use in applying therapeutic deep heat for selected medical conditions such as relief of pain, muscle spasms and joint contractures in the medical specialty of physical medicine.

The indications of the DermaWave 5000 Combi Max System also includes the treatment and relaxation of muscle spasms, prevention or retardation of disuse atrophy, increasing local blood circulation, muscle re-education, maintaining or increasing range of motion, immediate post-surgical stimulation of calf muscles to prevent venous thrombosis, symptomatic relief of chronic intractable pain, management of pain associated with posttraumatic or post-operative conditions using electrical stimulation and are indicated for the application of therapeutic deep heat for the treatment of selected medical conditions such as relief of pain, muscle spasms and joint contractures, relief of pain muscle spasms and joint contractures that may be associated with adhesive capsulitis, bursitis with slight calcification, myositis, soft tissue injuries, shortened tendons due to past injuries and scar tissues, relief of chronic and sub-chronic pain and joint contractures resulting from capsular tightness and capsular scarring using ultrasound.

- Dynatronics Corporation, Dynatron 150 Plus Ultrasound (K935728) .
- Excel Tech, XL Tek Ultra VM Ultrasound (K001166) .

The DermaWave 5000 Combi Max System utilizes identical accessories as those produced by MedX Health and share identical indications for use in physical medicine. Further, the MedX accessories comprising the MedX LCT 100 (K032231), MedX Duolight 500 (K032231) and the MedX 600 (K020017) are already cleared. The DermaWave 100 Accessory has almost identical heating characteristics as the MedX line of infrared lamp accessories and falls within the recommended guidelines for such devices in raising the temperature of tissue to no more then 45C in continuous operation over a set time period. The parameters used to achieve the comparative data are based on widely accepted clinical data that require heat lamp devices to elevate the temperature to above 40C and below 45C for a minimum 10 minute period. Comparative temperature charts are included in Section 10 of this submission.

The MedX and Duolight cleared accessories are connected to a control console that provides treatment time information to the user. The control console supplied by MedX and named the MedX 1000/1100 Console, is limited in its control features. The DermaWave 5000 Combi Max System employs sophisticated controls and control systems within system architecture to enhance the safety of the device in applications for which it is used.

## 7. Safety and Effectiveness Information

Validation documentation and a comparison of the technical characteristics and features were provided to demonstrate that the DermaWave 5000 Combi Max System is safe and effective, when indicated in specific applications in the medical specialties of physical medicine, general and plastic surgery and neurology.

## 8. Conclusion

The DermaWave 5000 Combi Max System was found to be substantially equivalent to the predicate devices and share similar indications for use and characteristics and functional features and are substantially equivalent to the currently marketed predicate devices.
