No
The description focuses on hardware connectivity and basic signal display, with no mention of AI/ML terms or functionalities.
No
The device is described as an "accessory for the MagPro stimulators" intended to "monitor evoked potentials." It functions as a diagnostic tool to capture and display EMG signals (Motor Evoked Potentials) and does not deliver therapy itself. The associated MagPro stimulators are therapeutic devices, but the MEP Monitor is explicitly for monitoring, not treatment.
Yes
Explanation: The device is intended to monitor evoked potentials (MEP), which are physiological responses used to assess the function of the nervous system, thus making it a diagnostic device. It captures EMG signals and displays MEP responses, which are used for diagnostic purposes.
No
The device description explicitly states it is a "small accessory device which is connected to the rear side of a MagPro magnetic stimulator" and has a "1 channel input" with a "Isolated input DIN-connector". This indicates it is a physical hardware component, not solely software.
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 examination of specimens derived from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, prevention, or treatment of a disease or condition.
- Device Function: The MEP Monitor is described as an accessory for magnetic stimulators that monitors evoked potentials by capturing EMG signals from surface electrodes. This involves measuring electrical activity from the body directly, not analyzing specimens taken from the body.
- Intended Use: The intended use is to "monitor evoked potentials," which is a physiological measurement, not an in vitro diagnostic test.
- Device Description: The description focuses on its connection to the stimulator and its ability to capture and display EMG signals from surface electrodes. There is no mention of analyzing bodily fluids or tissues.
Therefore, the MEP Monitor falls under the category of a medical device used for physiological monitoring, not an In Vitro Diagnostic device.

Max. stim. Frequency of 100 pulses per second is higher than

repetition rates because the charging of the power electronic is
not capable building up the full power between the pulses. At
100 pps the output power from MagPro is only 30% of full
power at 15pps.
High stimulation frequency is normal for current stimulator
devices. E.g. the current stimulator for the Neuro diagnostic

200Hz (pps) and Digitimer DS7A (K051357) with max.
