The description details a simple electrical stimulator with fixed parameters and basic circuit detection, with no mention of AI/ML terms or functionalities.
No.
The device is used for nerve localization during a procedure, not for treating a disease or condition.
No
The device is a peripheral nerve stimulator used for nerve localization during a procedure, which is an interventional or procedural aid rather than a diagnostic one. It doesn't diagnose a condition but rather facilitates a medical procedure.
No
The device description explicitly states it is a "battery powered peripheral nerve stimulator" and describes hardware components like a constant current source, electrodes (anode and cathode), and a nerve locating needle attachment. This indicates it is a hardware device with embedded software, not a software-only medical device.
No, the Stimtrode™ is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Stimtrode™ Function: The Stimtrode™ is a peripheral nerve stimulator used during a medical procedure (peripheral nerve block) to locate nerves using invasive electrodes/needles. It directly interacts with the patient's body to elicit a response (nerve twitch) for localization.
The Stimtrode™ is a medical device used for a procedural purpose, not for analyzing biological specimens.
N/A
Intended Use / Indications for Use
The StimtrodeTM is intended to be used by an anesthetist during a peripheral nerve block procedure for nerve localization using invasive electrodes/needles (supplied separately).

Device Description
The Stimtrode device is a battery powered peripheral nerve stimulators that can be used for
- · nerve locating using invasive electrodes/needles (not supplied)
The stimulus is generated by a constant current source. The waveform is a square wave with 3 options for pulse width. These are: 0.1, 0.3 and 0.5 milliseconds.
The units will continuously check for a closed circuit at 2Hz. Once a closed circuit is detected, the twitches will repeat at 2Hz, until an open circuit is detected.
The unit is permanently attached to the anode. The anode comprises a modified ECG type pad. The cathode comprises of a nerve locating needle that is attached at time of use.
