## Device Story

TNN-DU810 is a multi-modal therapy system combining ultrasound diathermy, neuromuscular electrical stimulation (NMES), and vacuum-based therapeutic massage. System includes console, control/display panel, ultrasound transducers, conductive electrodes, and vacuum roller head. Components function independently with no electrical interconnection. Operator (clinician) uses touch screen interface to adjust power, mode, and treatment parameters. Ultrasound provides thermal/mechanical effects for pain and circulation; NMES stimulates muscles for atrophy prevention and re-education; vacuum roller provides mechanical massage for circulation and cellulite appearance reduction. Device used in clinical settings to manage musculoskeletal conditions and post-surgical recovery. Output allows clinicians to deliver targeted physical therapy, potentially improving patient mobility, reducing pain, and managing muscle function.

## Clinical Evidence

No clinical data. Substantial equivalence is supported by non-clinical bench testing, including air flow, vacuum pressure, timer accuracy, electrical safety, and EMC testing.

## Technological Characteristics

Class I/II equipment, Type BF applied part. Dual-frequency ultrasound (1 MHz/3 MHz), NMES, and vacuum suction. Vacuum system: continuous/pulsed modes, max depression -820 mbar. Ultrasound intensity max 1.5 W/cm². Interface: touch screen with audio feedback. Components: ultrasound applicators, conductive electrodes, vacuum roller head. Software-controlled console. Sterilization: not specified (accessories are standard medical components).

## Regulatory 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.

#### Device Description: 5.

י

The TNN-DU810 Non-Invasive Subdermal Therapy System is comprised of the following main components:

- . A system console including software and control electrodes;
- A control and display panel: .
- Device accessories including muscle stimulator electrodes (ME2221, Mettler . Corp., K#013192) and cables, ultrasound transducers (applicators) (ME7513, Mettler Corp.) acoustic gel (Sonigel, Mettler Corp), and cables. The electrodes. ultrasound transducers and acoustic gel have all been cleared under the Mettler Electronics Corp. 510(k). Also included is a Dermosonic vacuum treatment roller head, cleared under the Dermosonic device. K024307.

The TNN-DU810 device has dual frequencies ultrasound therapy, muscle stimulator systems and therapeutic vacuum massager.

The user friendly interface comprises keyboard, touch screen and audio feedback. The screen provides operator information about operation mode and signal intersities. Large control knobs on the touch screen make adjusting power for ultrasound and muscle stimulation.

The system consists of the Alfatech DU857 device (K#052340) and the Dermosonic Therapeutic Vacuum Applicator, a component cleared in the Dermosonic K#024307 ..

The frequency Ultrasound Therapy, Muscle Stimulator System is identical to the DU857. It is important to note that there is no electric connection between the ultrasound therapy, muscle stimulator system and the therapeutic vacuum massager.

Each of the two components of the system (ultrasound plus neuromuscular stimulation) and the therapeutic massager function independently and have no connection between them.

### Discussion of Non-Clinical Tests Performed for Determination of Substantial 8. Equivalence as follows:

Performance testing to include: Air Flow Testing, Vacuum Pressure Testing, Timer Testing, etc. Also conducted: Electrical Safety Testing, EMC Testing, Risk Analysis, etc.

#### Discussion of Clinical Tests Performed: 9.

Not Applicable

#### 10. Conclusions:

·

The subject TNN-DU810 device is substantially equivalent to the predicate device (K#024307) in design and function, (using the predicate's own rollers and vacuum suction components) thereby achieving increased blood flow and therefore achieving temporary reduction in the appearance of cellulite.

Trade/Device Name: TNN-DU810 Subdermal Therapy System Regulation Number: 21 CFR 890.5860 Regulation Name: Ultrasound and muscle stimulator Regulatory Class: Class II Product Code: IMG, IMG, IMI, IPF, LIH and ISA Dated: March 15, 2007 Received: March 16, 2007

Dear Ms. Goldstein-Faulk:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0120. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (240) 276-3150 or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html.
