(88 days)
No
The description mentions software control using a microprocessor and different operation modes, but there is no mention of AI, ML, or any learning or adaptive capabilities. The device appears to be a standard electrical stimulator with pre-programmed modes.
Yes
The device is described as a combination of transcutaneous electrical nerve stimulator (TENS) and Interferential stimulation (IF) used for pain relief, and/or a powered muscle stimulator (EMS). Its intended uses include symptomatic relief of chronic pain, relaxation of muscle spasms, prevention of disuse atrophy, increasing circulation, muscle re-education, preventing venous thrombosis, and maintaining/increasing range of motion, all of which are therapeutic applications.
No.
The device is a stimulator (TENS, EMS, Interferential) for pain relief and muscle stimulation, not for diagnosing conditions. Its indications for use are therapeutic, not diagnostic.
No
The device description explicitly states it consists of a "stimulus generator" and "electrode," which are hardware components. While software controls the operation modes, the device is not solely software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The intended uses are for Transcutaneous electrical nerve stimulation (TENS), Power Muscle Stimulation (EMS), and Interferential Stimulation. These are all forms of electrical stimulation applied to the body for therapeutic purposes (pain relief, muscle function). None of these involve testing samples taken from the body (in vitro).
- Device Description: The device description details a stimulus generator and electrodes that apply electrical current to the patient's skin. This is consistent with external electrical stimulation, not in vitro testing.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any other components typically associated with in vitro diagnostics.
Therefore, the device described is a therapeutic electrical stimulator, not an in vitro diagnostic device.

Device Description
The GEM-STIM Combo Stimulator; Model: GM304/GM384/GM394 is the combination of transcutaneous electrical nerve stimulator(TENS) and Interferential stimulation (IF) used for pain relief and/or powered muscle stimulator(EMS) by applying an electrical current to electrodes, which are attached on the patient's skin. The output and waveform is adjustable according to the situation of patient.
The GEM-STIM Combo Stimulator: Model: GM304/GM384/GM394 consist mainly of two parts: the stimulus generator, electrode. The stimulus generates the output current specified as the input of controller. The output port transmits the output current to the electrode, which is attached to the patient's skin so as to transmit this stimulus current to the patient for pain relief or muscle stimulation of intended use purpose.
The GEM-STIM Combo Stimulator; Model: GM304/GM504 is basically the dual output channels unit which includes several different operation modes as mentioned on the comparison table. These operation modes are generated from the software control by using the microprocessor as its main control unit. And the model GM384/GM394 is the 4 channels model with the housing to install two independent units of GM504 and to provide the similar operation buttons which allow each unit of device being operated independently as that of the model GM504.
Basically the new models GM304/GM504/GM384/GM394 was developed from the predicate model GM38Y/Z (K042559). For the new models GM304/GM504/GM384/GM394, the stimulation waveform, significant specification, and the indication for use(IFU) were remained the same as that of Gemore 510(K) cleared predicate model GM38Y/Z (K042559).
