The logo consists of three blue squares nested inside each other, with the letters "BTL" in white inside the innermost square. To the right of the square logo is the text "BTL Industrie" in gray. # Substantial Equivalence The BTL 799-2L device is intended for improvement of abdominal tone, strengthening of the abdominal muscles, development of firmer abdomen; strengthening, toning and firming of buttocks and thighs; improvement of muscle tone and firmness, for strengthening muscles in arms, identically compared to the primary predicate device. Additionally, the BTL 799-2L device is intended for calves strengthening, toning and firming, which is supported by the secondary predicate device HPM-6000. The BTL 799-2L, when compared to the primary predicate device, may be used with two types of applicators. Applicator BTL 299-6 is identical to the applicator of the primary predicate device. The new applicator BTL 299-7 is of smaller size on the ground that it is intended to be used for smaller treatment areas, such as calves. The BTL 299-7 applicator has slightly higher magnetic field intensity and shorter pulse width when compared to the applicator of the primary predicate device. However, magnetic field {8}------------------------------------------------ Image /page/8/Picture/0 description: The image shows the logo for BTL Industries. The logo consists of three nested squares, with the letters "BTL" inside the innermost square. To the right of the square logo is the text "BTL Industries" in a simple sans-serif font. The logo is in blue, while the text is in gray. intensity is within the range of the BTL 299-2 applicator of the second predicate device. Pulse duration is shorter due to the smaller coil surface intended for smaller muscle parts. The applicator of the primary predicate device (BTL 299-6) has wider field exposure compared to the currently submitted BTL 299-7 applicator. This is because the BTL 299-7 coil is smaller than the one in the BTL 299-6 applicator, due to the fact that the BTL 299-6 applicator is intended for larger groups of muscles, while the new BTL 299-7 applicator is intended for smaller muscle parts, particularly arms and calves. All named applicators are based on identical principle, mechanism of action, as well as manufacturing material. The system console, consisting of the electromagnetic field generators, computer, and the touch-screen control panel is also identical to the predicate devices. Any differences between the predicate devices and BTL 799-2L device have no significant influence on safety or effectiveness of the BTL 799-2L device. Therefore, the BTL 799-2L device is substantially equivalent to the predicate devices. ### Conclusion Based upon the intended use and known technical information provided in this pre-market notification, the BTL 799-2L device has been shown to be substantially equivalent to currently marketed predicate devices.
