Intended Use
Transcutaneous Electrical Nerve Stimulator (Model:TENS WMPS2-1) can be used for the symptomatic relief of chronic intractable pain, post traumatic pain adjunctive treatment, and post-surgical pain adjunctive treatment.
Device Description
Transcutaneous Electrical Nerve Stimulator sends gentle electrical current to underlying nerves and muscle groups via electrodes applied onto the skin to relieve pain. The device has 16 programs (12 standard programs and 4 editable programs). It is a lithium battery-powered device comprising the electronic stimulatory module, the accessories of lead wires, the electrodes and the adapter. Two outlet sockets are used to connect skin electrodes by lead wires. The accessories of electrodes are 510(k) cleared devices (K192568). Size 50*50mm.
More Information

No
The summary describes a standard TENS device with pre-set and editable programs, but there is no mention of AI or ML capabilities, data analysis, or learning algorithms.

Yes.
The device is indicated for the symptomatic relief of chronic intractable pain, post traumatic pain adjunctive treatment, and post-surgical pain adjunctive treatment, which are therapeutic uses.

No

Explanation: The provided text describes the device as a Transcutaneous Electrical Nerve Stimulator (TENS) used for symptomatic pain relief. While it's a medical device, its function is to provide therapy (electrical stimulation for pain relief) rather than to diagnose a condition.

No

The device description explicitly states it is a lithium battery-powered device comprising an electronic stimulatory module, lead wires, electrodes, and an adapter, indicating it is a hardware device.

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 of chronic intractable pain, post traumatic pain adjunctive treatment, and post-surgical pain adjunctive treatment." This describes a therapeutic purpose, not a diagnostic one.
  • Device Description: The device description explains how it works by sending electrical current to nerves and muscles to relieve pain. This is a physical intervention, not a test performed on biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (like blood, urine, tissue, etc.) or providing information about a patient's health status based on such analysis.

IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Dear Doris Dong:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Please note that regardless of whether a change requires premarket review. the OS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
