No
The summary does not mention AI or ML, and the device description focuses on standard TENS functionality and wireless control via a mobile app with pre-defined modes. There is no indication of adaptive or learning algorithms.
Yes
Explanation: The device is intended for the relief of pain associated with sore or aching muscles, which is a therapeutic purpose. It is also described as a T.E.N.S. device, a type of therapeutic modality.
No
Explanation: The "Intended Use" section states the device is for "relief of pain associated with sore or aching muscles," which indicates a therapeutic purpose, not a diagnostic one. There is no mention of diagnosing conditions, identifying diseases, or evaluating physiological function.
No
The device description explicitly states it is a "portable battery powered T.E.N.S. device" with physical control buttons, indicating it is a hardware device with software control capabilities.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the relief of pain associated with sore or aching muscles. This is a therapeutic purpose, not a diagnostic one.
- Device Description: The device is a T.E.N.S. (Transcutaneous Electrical Nerve Stimulation) device. T.E.N.S. devices deliver electrical impulses to the skin to alleviate pain. This is a physical therapy modality, not a method for diagnosing conditions by examining samples from the body.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing information about a disease or condition
- Using reagents or assays
In summary, the SmartTENS device is a therapeutic device for pain relief, not a diagnostic device that analyzes samples to provide information about a patient's health status.

Device Description
SmartTENS is a portable battery powered T.E.N.S. device with a wireless remote control feature for over-the-counter use, mainly operating in home, clinic, or hospital environments.
There are three control buttons on the unit itself: ON/OFF, intensity UP and intensity DOWM. The device is also designed to be controlled wirelessly through Bluetooth 4.0 connection (Frequency: 2402.0 - 2480.0 MHz) by a matched smart phone, which is featuring a mobile application (App) developed by EasyMed Instruments Co., Ltd.
A user entered 6-digit security code ensures the access to the device can only be the user's matched smart phone, thus avoiding unauthorized controls to the device.
There are totally seven (7) modes that are intended for pain relieving treatments to the following areas: Shoulder/ Arm, Lower Back and Leg/Foot. The specifications of each mode will be described in greater details in the User Manual.
Accessories:
M-CBX-C-008 Button-affixed Electrode
P-AE-002-A Replaceable Hydrogel Pads (gel-pads) 73mm x 62mm for external use. Pack of 2*
CBX-057-B Charger Cradle
M-PA-004-B Charging Adaptor
The accessories include an electrode and two hydrogel pads (gel-pads). The electrode is connected to the device by snapping the two buttons onto the device. One side of the adhesive gel-pads adheres to the electrode, and the other side adhere the device to the healthy intact skin of the user's body. Generally, the device produces either a fixed or modulated electrical signal through electrodes normally placed over the area of pain.
A built in Li-Ion battery is the power source of the device, which can be recharged for a limited large number of times. To charge the device, remove the electrode assembly by unsnapping it off the device, place the device on the charger cradle, insert the small pin of the charging adaptor into the charge cradle, and connect the charging adaptor to the electrical power supply.

DIFFERENCES BETWEEN NEW DEVICE AND PREDICATE DEVICES
The technical characteristics of SmartTENS are similar to those of the predicate devices in design, intended use and function. Like the predicate device EasyStim TN28 OTC (K140168) and WiTouch™ Pro (K120398), the SmartTENS is a device used to apply an electrical current to electrodes on a patient's skin to relieve pain. The stimulation parameters of new device EasyStim TN28 OTC are same as those of predicate device EasyStim TN28 OTC (K140168) and similar to those of WiTouch™ Pro (K120398).
The predicate device EasyStim TN28_OTC (K140168) utilizes flexible wires between the electrodes and the electical stimulus generator. However, the new device SmartTENS utilize wireless remote controls for the considerations of a more user friendly design, which is similar to WiTouch™ Pro (K120398).
The intended design of SmartTENS limits the application for use to sites of lower back, arms and legs. The design includes Thermal Plastic Elastomer (TPE) electrodes that are intended for reuse and are button-affixed to the electrical stimulus generator. The unique connection makes the electrodes integral to the generator. The connection and shape of the electrodes limit application of the device. These unique characteristics of the integral electrodes are similar to those of WiTouch™ Pro (K120398) and insignificant as it relates to safety and effectiveness, which is not critical to the intended use between the referenced predicate devices.
The predicate device EasyStim TN28 OTC (K140168) utilizes affixed buttons as the sole method to control the electrical stimulus generator. The new device SmartTENS utilizes an additional method of a wireless remote control which similar to the predicate device WiTouch™ Pro (K120398). The difference is WiTouch™ Pro (K120398) utilizes radio frequency transveiver to control the electrical stimulus generator, while the SmartTENS ultilzes Bluetooth 4.0 as the wireless connecting technology to control the electrical stimulus generator. Furthermore, the remote controller is the Mobile Medical Application that need to be installed in the smart phone. This uniqueness of controlling the electrical stimulus generator by utilizing a Bluetooth wireless connecting technology is insignificant as it relates to safety and effectiveness, and is not critical to the intended use between the device and the referenced predicate devices.
Technological characteristics, features, specifications and intended uses of the new device SmartTENS are substantially equivalent to the referenced predicate devices. The differences that exist between SmartTENS and predicate devices are insignificant in the terms of safety or effectiveness.

CONCLUSION:
The new device SmartTENS has the same indications for use and similar technological characteristics to the predicate device EasyStim TN28 OTC (K140168) and WiTouch™ Pro (K120398). The stimulation parameters of new device SmartTENS are all in the same range of those of predicate devices. Thus, the new device SmartTENS is substantially equivalent to the predicate devices and any differences between the devices do not pose any new questions of safety and effectiveness.
