No
The device description focuses solely on the physical characteristics and function of surface electrodes for electrodiagnostic procedures. There is no mention of any software, algorithms, or data processing that would suggest the use of AI or ML.
No
The device is described as being used with electrodiagnostic equipment for recording and stimulating, which falls under diagnostic purposes rather than therapeutic treatment.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the electrodes are "intended for use with electrodiagnostic equipment for the recording of electrophysiological activity from peripheral nerves and muscles." The "Device Description" further elaborates that they "transduce bioelectric signals into electronic signals for measurement of bioelectrical phenomena in the body, such as peripheral nerve or muscle responses" and are "used in the performance of nerve conduction studies (NCS)." These functions are inherent to diagnostic processes.
No
The device description explicitly details physical electrodes (Stimulator Bar Electrode, Tab Electrode Set, Ring Electrode Set) which are hardware components used for interfacing with the patient and electrodiagnostic equipment. The summary does not mention any software component as the primary or sole medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The NeuroMetrix UNIVERSAL Electrodes are surface electrodes that interface with electrodiagnostic equipment to record electrophysiological activity from peripheral nerves and muscles, and for electrical stimulation of peripheral nerves. This involves direct interaction with the patient's body, not the analysis of specimens taken from the body.
- Intended Use: The intended use clearly states recording and stimulation of peripheral nerves and muscles, which are in-vivo (within the living body) procedures.
Therefore, the function and intended use of these electrodes fall outside the scope of In Vitro Diagnostics. They are considered medical devices used for electrophysiological measurements and stimulation directly on the patient.
N/A
Intended Use / Indications for Use
The NeuroMetrix UNIVERSAL Electrodes are intended for use with electrodiagnostic equipment for the recording of electrophysiological activity from peripheral nerves and muscles, and for peripheral nerve electrical stimulation. UNIVERSAL Electrodes are non-sterile and are for single patient use only.

6. BASIS FOR SUBSTANTIAL EQUIVALENCE
A comparison of the UNIVERSAL Electrodes to the predicate Axon Systems Pre-gelled Surface Electrodes (K062198), along with testing data presented, support a finding of substantial equivalence. The UNIVERSAL Electrodes and these predicate electrodes share similar intended use, clinical applications, and technological characteristics.
The UNIVERSAL Electrodes include a connector, an electronic serial number (UE-001 only), EEPROM memory (UE-001 only), and the measurement of patient skin-surface temperature (UE-001). These technological characteristics are substantially equivalent to the NeuroMetrix Biosensors (K060584).
