The document describes a standard electrical stimulator with no mention of AI or ML capabilities. The device description focuses on hardware components and basic functionality.
Yes
The device description, intended use, and indications for use clearly state that it is designed to provide symptomatic relief of pain, muscle relaxation, improve circulation, and other therapeutic effects for various conditions.
No
The device is a stimulator designed for symptomatic relief, muscle relaxation, and prevention of muscle atrophy, not for identifying or diagnosing a condition.
No
The device description explicitly lists hardware components such as a stimulation unit, support belt, electrode, and snap cable, indicating it is not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description clearly states that the ETG 255 Combo Stimulator and TEN 260 Stimulator are non-invasive devices. They apply electrical stimulation externally to the body.
- Intended Use: The intended uses listed are for pain relief (TENS mode) and muscle stimulation (EMS mode). These are therapeutic applications, not diagnostic tests performed on specimens.
The device is a therapeutic electrical stimulator, not a diagnostic device that analyzes samples.

Device Description
Care back pain relief stimulator, which includes models TENS 7000 and LT3074 are non-invasive devices which are tented for over the counter use in temporary relief of pain associated with sore and aching muscles in the lower back due to strain form exercise or normal household and working activities.
The devices contain the following main parts: TENS stimulation unit, Support Belt, electrode, and snap cable.
The electrode is permanently sewn up in the support belt. Each belt is flexible, and is available in range of sizes to ensure good patient contact. A male snap connector is placed within the electrode and is connected via the female snap connector to a short lead wire. The lead wire has a female pin connection at the distal end which accepts the lead wire connection from the stimulator.
The device can be worn on the low back part of user so as to place the electrode on the treatment location of low back.
