Intended Use
Rhythmlink International 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), Electroencephagraph (EEG) and Nerve potential signals. The electrodes are sterile and for single patient use only.
Device Description
Rhythmlink International Subdermal Needle Electrodes are single patient use, disposable, sterile devices. Electrodes are applied in the study of biopotentials such as electroencephalograph (EEG), electromyograph (EMG), nerve conduction and stimulation/response. Electrodes are invasive as they are placed subcutaneously or in contact with nerve or muscle tissue. The electrodes consist of a stainless steel needle with a lead wire attached. The lead wires terminate in a safety connector that cannot be connected to an AC power outlet. The electrodes provide the patient contact device. The electrodes connect to the user's recording, monitoring and stimulation/response equipment. The electrodes are used under the supervision of a physician.
More Information

No
The document describes a passive electrode device for recording biopotential signals and does not mention any computational or analytical capabilities that would involve AI or ML.

No
The device is described as being used for "recording of biopotential signals" and for "stimulation/response," which indicates a diagnostic or monitoring function rather than providing therapy.

Yes

Explanation: The device is used for recording biopotential signals such as EMG, EEG, and nerve potential signals, which are used to assess the physiological state and function of the body, indicating a diagnostic purpose.

No

The device description clearly states that the device consists of a stainless steel needle with a lead wire and connector, which are physical hardware components. It is 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 medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health. These tests are performed outside of the body.
  • Device Description: The Rhythmlink International Subdermal Needle Electrodes are described as being placed subcutaneously or in contact with nerve or muscle tissue. This means they are used within the body to record electrical signals directly from tissues.
  • Intended Use: The intended use is for recording, monitoring, and stimulation of biopotential signals like EMG, EEG, and nerve potentials. These are measurements of electrical activity within the body, not tests performed on samples taken from the body.

Therefore, the device's function and application clearly fall outside the scope of In Vitro Diagnostics.
