Intended Use
Spes Medica Subdermal Needle Electrodes are intended for use with recording, monitoring and stimulation equipment for the purpose of recording of biopotential signals. Examples include: Electromyography (EMG), Electroencephalography (EEG) and Nerve potential signals. The electrodes are sterile and for single patient use only.
Device Description
Spes Medica Subdermal Needle Electrodes are monopolar needles intented to use for Electromyography (EMG), Electroencephalograph (EEG) and Nerve potential signals in example and they are intended for use with recording, monitoring and stimulation equipment for the purpose of recording of biopotential signals. The Subdermal Needle Electrodes are used for recording and stimulation (micro stimulation), this stimulation has no therapeutic purpose but has the purpose of activating an electrical response.
More Information

Not Found

No
The document describes a physical medical device (needle electrodes) and its performance in standard biological and electrical safety tests. There is no mention of software, algorithms, or data processing that would suggest the use of AI or ML.

No
The device is described as having "no therapeutic purpose" and is intended for recording and monitoring biopotential signals.

Yes

The device is intended for recording biopotential signals such as EMG, EEG, and nerve potential signals, which are used to diagnose neurological and muscular conditions.

No

The device description explicitly states it is a "Subdermal Needle Electrode," which is a physical hardware component used for recording and stimulating biopotential signals. The performance studies also focus on physical properties and biological interactions of the electrode.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Function: The description clearly states the device is a "Subdermal Needle Electrode" intended for "recording of biopotential signals" such as EMG, EEG, and nerve potential signals. It also mentions "stimulation (micro stimulation)" for activating an electrical response.
  • Method of Use: The device is used by inserting needles subdermally (under the skin) to directly measure electrical activity within the body. This is an in vivo (within the living body) measurement, not an in vitro (in glass/outside the body) test on a sample.

The device is a medical device used for physiological measurement and stimulation, but it does not fit the definition of an In Vitro Diagnostic.
