No
The device description details a standard electrical stimulation device with manual controls and no mention of adaptive algorithms or data processing that would indicate AI/ML.
Yes
The device is described as being "intended for use in the symptomatic relief of chronic intractable pain, post traumatic acute pain, and post surgical pain," which are therapeutic applications.
No
The device description and intended use clearly state that it is for "symptomatic relief of chronic intractable pain, post traumatic acute pain, and post surgical pain," indicating a therapeutic rather than diagnostic purpose. It administers treatment through electrical stimulation.
No
The device description explicitly states it consists of a battery-powered instrument with hardware components like channels, a hand-held probe, electrodes, and a grounding pole.
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 symptomatic relief of pain. This is a therapeutic purpose, not a diagnostic one. IVDs are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The device is a battery-powered instrument with electrodes and a probe that delivers electrical stimulation. This is consistent with a device used for physical therapy or pain management, not for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any processes related to in vitro testing.
The device described is a TENS (Transcutaneous Electrical Nerve Stimulation) unit, which is a type of medical device used for pain relief. The predicate device listed (TX-3 TENS) further confirms this.

Device Description
The device consists of a battery powered instrument with four channel outputs. A hand held probe allows treatment at individual sites. Output polarity, frequency, intensity, and voltage are controlled by four independent channels. Each channel drives a pair of self adhesive electrodes. A grounding pole electrically grounds the device when using the hand held probe.

Proprietary name: Common or usual name:
Classification name:
AWQ-104 transcutaneous electrical nerve stimulator (TENS) Transcutaneous electrical nerve stimulator, Class II, 21 CFR 882.5890.
Legally marketed device for substantial equivalence comparison: TX-3 TENS, K913532
Description of the device:
The device consists of a battery powered instrument with four channel outputs. A hand held probe allows treatment at individual sites. Output polarity, frequency, intensity, and voltage are controlled by four independent channels. Each channel drives a pair of self adhesive electrodes. A grounding pole electrically grounds the device when using the hand held probe.
Intended use of the device:
The AWQ-104 is intended for use in the symptomatic relief of chronic intractable pain, post traumatic acute pain, and post surgical pain. It can be used by a physician on his patients. This is a prescription device and should be used under continued medical supervision. The intended use of the TX-3 TENS is identical. It does not have curative value, but relives pain symptoms.
The AWQ-104 cannot be used transcerebrally, in the carotid sinus area or during pregnancy. Patients suspected of having heart disease should consider adequate precautionary measures prior to administration. Severe spasm of the laryngeal and pharyngeal muscles may occur when an electrode is placed across the neck or mouth. This may be enough to close off the airway. Stimulation will inhibit the output of some demand cardiac pacemakers and therefore, is not recommended for patients with this type of pacemaker.
Electrical nerve stimulation is a symptomatic treatment, and as such may suppress the progress of pain which would otherwise serve as a protective influence

on the outcome of a disease process. The potential for physical and/or psychological dependence upon nerve stimulation as a means of relieving pain has not been determined.
It has been noted that some patients find the sensation of electrical stimulation extremely unpleasant and should probably be excluded from further use of the stimulator.
Technological Characteristics:
Both devices use one 9 volt battery. During stimulation, the electrical output for both devices is square waveform pulses. Details of electrical output are different but new safety concerns are not raised by the differences. Controls on each device modulate pulse outputs and regulate stimulation intensity. Material composition of the electrodes is identical. Electrode 510(k) number: K946230.
Performance:
The AWQ- 104 has been designed and tested to conform to the following standards:
ISO 14971:2000 EN ISO 10993.1:1997/EN ISO 10993.5:1999/ EN ISO 10993.10.2002 EN 60601-1:1990+A1:1993+A2:1995+A13:1996/ IEC 60601-1:1988+A1:1991+A2:1995 EN 60601-1-2:2001/IEC 60601-1-2:2001 EN 980:2003
