No
The device description focuses on the physical properties and electrical conductivity of garment electrodes, with no mention of AI or ML for signal processing, analysis, or any other function.
No.
The device is an electrode garment intended to be used with legally marketed TENS devices, which are therapeutic, but the garment itself is a component that delivers stimulation signals and does not generate therapeutic effects on its own.
No
This device is described as an electrode that transmits electrical stimulation signals generated by a stimulator to the body surface. It is intended to be used with legally marketed TENS devices (Transcutaneous Electrical Nerve Stimulation devices), which are typically for therapeutic purposes (e.g., pain relief) rather than diagnostic ones. The text specifies that "The Well-Life Garment Electrodes (GM Series) will deliver the stimulation signals generated by the stimulator to the body surface." This indicates a delivery function, not a diagnostic one.
No
The device is a garment electrode made of conductive and non-conductive textiles, which is a hardware component. It is intended to be used with legally marketed TENS devices, which are also hardware. The description focuses on the physical properties and performance of the garment itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for delivering stimulation signals from a TENS device to the body surface. This is a therapeutic application, not a diagnostic one.
- Device Description: The description details how the garment electrodes function to transmit electrical signals to the skin for stimulation. This aligns with the intended therapeutic use.
- Lack of Diagnostic Elements: There is no mention of the device being used to analyze biological samples (blood, urine, tissue, etc.) or to provide information for the diagnosis of a disease or condition.
- Performance Studies: The performance studies focus on safety (biocompatibility) and the electrical performance of the electrodes in transmitting stimulation signals. These are relevant to a therapeutic device, not an IVD.
IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic purposes. This device operates in vivo (on the body) and is used for therapeutic stimulation.

Device Description
Well-Life Garment Electrodes (GM, Series), Models AM and EB, are intended to be used with legally Marketed Transcutaneous Electrical Nerve Stimulation (TENS) devices which could be used in place of traditional cutaneous electrode patches. The Well-Life Garment Electrodes (GM Series) are blended with Nonconductive textiles (polyurethane, nylon and polyester) and conductive textiles (Silver Fabric). Non-conductive area is used to fix and support Well-Life Garment Electrodes (GM Series) on the body. Two types of Garment Electrodes are designed.
The different series of model means different placement of the garment electrode. For "AM" it is to be place around the arm with conductive areas are on the upper arm and lower arm and there are two sets of snap facing outward, finally for "EB" it is to be place around the elbow with conductive area surrounds the elbow and there are one sets of snap facing outward. There are three sizes for each series of model (S/M/L). The conductive area between different sizes is fixed. There is four conductive area divided into upper arm area and lower arm area on model "AM", the areas is a pair of 39 cm² and a pair of 39 cm². There is only two conductive area on model "EB", the areas is a pair of 25.5 cm2.
By adjusting the area of the non-conductive area, the customer's body curve can be fitted. Conductive area is used as a transmission interface which enabling electrical stimulation devices to transmit signals to the skin. The devices must be used wet when in contact with the skin. When using Well-Life Garment Electrodes (GM Series), buckle the one port of lead wire or any connection terminal from legally marketed stimulator to the set of closest snap buttons on Garment Electrodes. Make sure electrical signals could reach the path from electrical stimulation to the Garment Electrodes.
For Garment Electrodes with multiple sets of buttons, only one set of buttons can be used at a time. The surface of conductive area has a resistance of less than 14 ohms per inch. The signal is generated by an electrical stimulator, and is transmitted evenly through the wire to the conductive area of the Garment Electrodes, and transmitted to the skin.

Comparison in Detail(s):
Note 1: The description are partially different among Subject Device, Primary Predicate Devices, and secondary Predicate Devices but the Intended Use/ Indication for use are similar. They are all used to deliver the stimulation signals generated by electrical stimulator to the body surface.
Note 2: Electrode conductive area and Impedance Parameters
Although the subject device has 14 ohms per inch. which is different from the predicate device, "Maximum Average Current Density" and "Maximum Peak Power Density" property are similar and do not raise new questions of safety or effectiveness.
The standard of "Maximum Average Current Density" refers to "IEC60601-2-10 Clause 201.4.2" and the standard of "Maximum Peak Power Density" refer to "Guidance Document for Powered Muscle Stimulator 510K Section 3." Indicating similar performance and safety between subject device and predicate device. Otherwise the subject devices are complying with ISO 10993 requirements. So the differences of the function specifications will not raise any safety or effectiveness issue. For detailed measurement data, please refer to the above table. The subject device are Substantially Equivalent to the predicate device.
Note 3: Washable or not.
Subject Device, Primary Predicate K053214 and Secondary Predicate K171721 are made of textiles and can be washed. The subject device are Substantially Equivalent to the predicate device.

10.2. Conclusion:
Although the Note 1: description of Intended Use, Note 2: Design (shape) and size, Note 3: Electrode conductive area and Impedance Parameters, Note 4: Washable or not aren't exactly as same as the Predicate devices, all of their functions and performance are applying in the corresponding device, such as Electrical Stimulator, are substantially equivalent with Predicate device. After Comparison and Evaluation, the subject device Well-Life Garment Electrodes (GM series) has similar features to predicate devices. The few differences are explained and do not impact of the safety and effectiveness. Thus, the subject device is substantially equivalent with Predicate device.
