No
The summary describes a standard electrical stimulator and does not mention any AI or ML components or functionalities.
Yes
The device is described as an interferential stimulator with TENS indications used for symptomatic relief and management of chronic intractable pain, which directly serves a therapeutic purpose by alleviating symptoms and managing a medical condition.
No
Explanation: The device is described as an interferential stimulator with TENS indications used for symptomatic relief and management of chronic pain, and it delivers electrical current to relieve pain. This indicates a therapeutic, not diagnostic, function.
No
The device description explicitly states that the device "generates the small true-sine pulses of electrical current" and delivers it through "cable and electrode placed on skin," indicating it includes hardware components for electrical stimulation.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "symptomatic relief and management of chronic intractable pain" through electrical stimulation applied to the patient's skin and nerves. This is a therapeutic application, not a diagnostic one.
- Device Description: The device generates electrical current to stimulate the body. This is a physical intervention, not a test performed on biological samples in vitro (outside the body).
- Lack of IVD Characteristics: The description does not mention analyzing biological samples (blood, urine, tissue, etc.) or providing information about a patient's health status based on such analysis.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
The WL-2206A1 and WL-2206A2 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. Through the current stimulation the chronic and/or acute pain is to be relieved.

Contact: Mr. Mike Price
- Submitter's Identifications: Theratech, Inc. 1109 Myatt Blvd, Madison, TN 37115
Date of Summary Preparation: March 2006.
2. Name of the Device:
IF series True sine interferential stimulator / Model: WL-2206A1 & WL-2206A2.
3. Information of the 510(k) Cleared Device (Predicate Device):
WL-2206A (K050847) .
4. Device Description:
The WL-2206A1 and WL-2206A2 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. Through the current stimulation the chronic and/or acute pain is to be relieved.
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 for the statement of indications and contraindication for use are provided hereafter.

6. Discussion of Non-Clinical Tests Performed Determination of Substantial Equivalence are as a 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.

- Conclusions
-
The true sine interferential stimulator, model WL-2206A1 & WL-2206A2, has the same intended use and technological characteristics as the cleared device of WL-2206A (K050847). 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.

Dear Mr. Price:
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.
