Dear David Chmel:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

#### Technological Characteristics

The BTL 799-2 device has the same indications for use and similar technological characteristics and principles of operation as its predicate device. The BTL 799-2 device and its predicate are comprised of a system console and applicator(s). The system console consists of the electromagnetic field generators, computer, and the touch-screen control panel.

Generated electromagnetic field is intended to interact with the tissues of the human body to achieve muscle stimulation. The Essential technical characteristics of the BTL 799-2 and its predicate device, particularly the type of energy, pulse characteristics, type of operation and therapy time, are identical.

Compared to the predicate, the BTL 799-2 device is equipped with larger touch-screen control panel to increase user comfort. Technical characteristics of the applicator are comparable to its predicate. The subject device has two outputs to enable simultaneous treatment by two applicators.

The technological differences between the BTL 799-2 device and the predicate device do not raise any new types of safety or effectiveness questions.
