Device Description

The subject device delivers electric pulses generated to the user's body areas such as the back and foot through the electrodes. The devices include operating elements, such as the ON/OFF button, intensity increase button, and intensity decrease button, and could be attached to electrodes. The device has multiple program modes of different pulse frequencies, covering TENS and PMS that is also called Electrical Muscle Stimulation (EMS). the device may also provide heat for temporary relief of minor aches and pains.
The device could be easily operated through its buttons to manually realize its functions, such as turning on/off and increasing/decreasing intensity, providing heat/light if needed. The optional wireless control via a remote or Bluetooth APP could provide a secondary operation way to the user, who could be able to wirelessly realize the functions mentioned above.
The electrodes cleared include the electrode patches/pads and electrode garments, which could be packaged together with the 510(k)-cleared devices or packaged separately as the replacement electrodes for 510(k)-cleared devices. The exact percentage of ingredients (such as lidocaine, menthol, and/or cannabidiol) used in the biocompatible electrodes is withheld as the trade secret and may be disclosed as requested.

AI/ML Overview

The provided text is a 510(k) Summary for the StimPlus Patch, a Transcutaneous Electrical Nerve Stimulator (TENS) and Powered Muscle Stimulator (PMS) with heating function. The document focuses on demonstrating that the subject device is substantially equivalent to legally marketed predicate devices, not on proving that the device meets specific acceptance criteria through a clinical study involving human patients.

Therefore, many of the requested details about acceptance criteria, study design, expert involvement, and ground truth establishment (especially pertaining to clinical performance) cannot be extracted from this document because the submission method relies on demonstrating substantial equivalence to pre-existing, cleared devices rather than a de novo clinical performance study.

However, I can extract the information related to the non-clinical tests and the comparison of the device's technical specifications to those of its predicates, which serve as a form of "acceptance criteria" for demonstrating substantial equivalence.

Here's the breakdown of what can and cannot be answered based on the provided text:


1. A table of acceptance criteria and the reported device performance

The acceptance criteria for this 510(k) submission are based on demonstrating "substantial equivalence" to predicate devices. This is achieved by showing that the subject device has the same intended use and similar technological characteristics, or that any differences do not raise new questions of safety or effectiveness. The core of this is the comparison table of technical parameters.

7. Substantial Equivalence

As shown in the above table, the subject device and predicate device are identical or similar. The differences between the subject device in this submission and the predicate device in K162517 and K141260 do not raise any new issues of safety or effectiveness, as discussed below.

The program modes of the subject device are from those of the predicate device. Both the subject device and the predicate device have the substantially equivalent technical specifications that are within the range of FDA cleared transcutaneous electrical nerve stimulators. In addition, the output voltage, output current, phase charge, current density, and average power density are set and delivered at a oneby-one level by the user to a strong but comfortable sensation, so the output voltage, output current, phase charge, current density, and average power density delivered are therapeutically effective with either device. Therefore, the differences of maximum output voltage, maximum output current, maximum phase charge, maximum current density, and maximum average power density between the subject device and the predicate device does not raise new questions of safety or effectiveness.

As demonstrated, the ornamental differences between the subject and predicate devices do not affect the intended use or alter the fundamental technology of the device. There are no new safety or
