Intended Use
Non-invasively monitoring of the laryngeal nerves during thyroid surgery, and of the Xth cranial nerve during skull-base surgery.
Device Description
Disposable Laryngeal Electrodes are non-invasive. The disposable device is constructed using a medical grade ink as electrode material suspended on a polyethylene substrate; a polyester connector with a separate available cable assembly or DIN 42802 connectors; The electrode is available in three sizes to suit different sexes and age groups. The 4/5mm electrode should be used with an 4 or 5mm endotracheal tube; the 6/7mm electrode should be used with a 6 or 7mm endotracheal tube; the 8/9mm electrode should be used with an 8 or 9mm endotracheal tube. The cable assembly is available separately and will have a long life if it is not abused and is stored appropriately. Using the laryngeal electrode lowers the risk of damage to the laryngeal or Xth cranial nerve (the Vagus nerve) during thyroidectomy or parathyroidectomy and, since it is noninvasive, it also lessens the risk of infection during the monitoring procedure.
More Information

No
The description focuses on the physical characteristics and function of a disposable electrode for nerve monitoring, with no mention of AI or ML algorithms for data analysis or interpretation.

No.
The device's stated intended use is "Non-invasively monitoring of the laryngeal nerves during thyroid surgery, and of the Xth cranial nerve during skull-base surgery," which means it is a diagnostic/monitoring device, not one that treats a condition. Its function is to lower risk of damage, not to treat existing damage or a condition itself.

No

The device is used for "monitoring" the laryngeal nerves during thyroid surgery and the Xth cranial nerve during skull-base surgery, specifically to "lower the risk of damage" to these nerves. While it provides real-time information, its primary purpose is to guide the surgeon during the procedure to prevent injury, rather than to diagnose a condition or disease.

No

The device description explicitly details physical components like electrodes, a polyethylene substrate, a polyester connector, and a cable assembly. It also mentions different sizes of the electrode and sterilization, which are characteristics of hardware devices, not software-only devices.

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, tissue) to provide information about a person's health.
  • Device Function: This device is used for monitoring nerve activity during surgery. It is applied externally (non-invasively) and does not analyze samples taken from the body.
  • Intended Use: The intended use is to "monitor" laryngeal and cranial nerves, not to diagnose a condition based on analyzing biological samples.

The device is a surgical accessory used for nerve monitoring during specific procedures.

Intended Use / Indications for Use

The Disposable Laryngeal Electrodes are intended for non-invasive use attached to a endotracheal tube and positioned for continuous EMG monitoring of the larynx during surgical procedures with recording and monitoring equipment, (active and reference), of Electromyography (EMG). The electrodes are designed for single-patient application use. The electrodes are intended for use only by a licensed physician.
