More Information

Not Found

No
The summary describes a disposable needle electrode for EMG, focusing on its physical and electrical properties. There is no mention of AI or ML in the intended use, device description, or performance studies.

No
The device is used to measure muscle activity for diagnostic purposes (EMG), not to treat a condition.

Yes

The device records electrical activity within the muscle (EMG signals) to differentiate between muscle and nerve diseases, which is a diagnostic purpose.

No

The device description explicitly states it is a "Single Patient EMG Needle Electrode" and describes physical characteristics and testing related to the needle itself (penetration, friction force, electrical properties), indicating it is a hardware device.

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

Here's why:

  • Intended Use: The intended use is for "muscle activity recording for Electromyography (EMG) applications." This involves measuring electrical signals directly from the muscle tissue in vivo (within the living body).
  • Device Description: The device "is used to measure an EMG signal when connected to the EMG equipment." This further confirms its function as a sensor for in vivo electrical activity.
  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, outside of the body (in vitro) to detect diseases, conditions, or infections.

This device is a medical device used for in vivo physiological measurement, not for testing samples in vitro.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The non-clinical tests performed are laboratory tests to verify the functionality of the Ambu Neuroline Disposable Concentric needle electrode. The Ambu Neuroline Disposable Concentric needle electrode is tested for penetration and friction force and electrical properties. The verification of the penetration and the friction force of the needle were performed according to DIN 13097.

Ageing tests are performed to verify and ensure the functionality during the shelf life of the product.

No clinical tests were performed for the updated version of the Ambu Neuroline Disposable Concetric needle because it has the same intended use and similar characteristics as the currently commercially available Ambu Neuroline Disposable Concentric needle.

    1. Description of device

1

The Ambu Neuroline Concentric Needle is a Single Patient EMG Needle Electrode and is used to measure an EMG signal when connected to the EMG equipment through a 5 pins reusable cable. The Electromyogram (EMG) records electrical activity within the muscle. It is used mainly to tell the difference between muscle diseases and nerve diseases. The Ambu Neuroline Concentric Needle is a sterile product.

9. The intended use

Ambu Neuroline Disposable Concentric needle electrodes is used for electromyography (EMG) recording for examination of the peripheral neuromuscular system, by registration of the electrical activity from the muscles. This is used to assess whether muscle impairment is due to disturbances in the motor neurones, the motor nerve fibres or in the muscle itself. It is used mainly to tell the difference between muscle diseases and nerve diseases.

10.Indications for Use

The Neuroline, Disposable Concentric needle electrodes are made for muscle activity recording for Electromyography (EMG) applications. The electrodes are for single patient use only.

11. Summary of the technoloqical Characteristics

Ambu Neuroline Concentric Needle consists of a cannula made of stainless steel and an inner conductor. In between these two conductors there is an insulation layer. The inner conductor is the active measure point and the outer conductor of stainless steel is the reference point. The Stainless steel cannula is coated with a low friction polymer.

12. Brief discussion of the nonclinical tests submitted

The non-clinical tests performed are laboratory tests to verify the functionality of the Ambu Neuroline Disposable Concentric needle electrode. The Ambu Neuroline Disposable Concentric needle electrode is tested for penetration and friction force and electrical properties. The verification of the penetration and the friction force of the needle were performed according to DIN 13097.

Ageing tests are performed to verify and ensure the functionality during the shelf life of the product.

13. Brief discussion of the clinical tests submitted

No clinical tests were performed for the updated version of the Ambu Neuroline Disposable Concetric needle because it has the same intended use and similar characteristics as the currently commercially available Ambu Neuroline Disposable Concentric needle.
