Name of the Device: IF series True sine interferential stimulator / Model: WL-2206B & WL-2106E. ## 3. Information of the 510(k) Cleared Device (Predicate Device): WL-2206A2 (K060975). ## 4. Device Description: The WL-2206B and WL-2106E are the device which generates the small true-sine pulses of electrical current. The generated current may be delivered to the patient skin and/or underlying nerves through the cable and electrode placed on skin. ## 5. Intended Use: The device is an interferential stimulator with TENS indications used for symptomatic relief and management of chronic intractable pain. In addition, the standard format for the statement of indications and contraindication for use are provided hereafter. ## 6. Substantial Equivalence Comparison The WL-2206B and WL-2106E have output characteristics and controls that are identical to those of the predicate device. The new devices are different in that WL-2106E is controlled using knobs and multi-position switches versus input buttons in conjunction with an LCD display. WL-2206B is functionally identical to WL-2206A2. {1}------------------------------------------------ ## 7 . Discussion of Non-Clinical Tests Performed Determination of Substantial Equivalence are as follows: Compliance to applicable voluntary standards includes ANSI/AAMI, NS4-1985, as well as EN 60601-1, and EN 60601-1-2 requirement. In addition to the compliance of voluntary standards, the software verification has been carried out according to the FDA software guidance. ## 8. Conclusions The true sine interferential stimulator, model WL-2206B & WL-2106E, has the same intended use and technological characteristics as the cleared device of WL-2206A2 (K060975). Moreover, verification and validation tests contained in this submission demonstrate that the difference in the submitted demonstrate that the difference in the submitted models could maintain the same safety and effectiveness as that of cleared device. In the other words, those engineering difference do not: (1) affect the intended use or (2) alter the fundamental scientific technology of the device. {2}------------------------------------------------ ## DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/2/Picture/1 description: The image shows the logo for the U.S. Department of Health and Human Services.
