No
The summary describes a standard electrosurgical device and does not mention any AI or ML components or functionalities.

Yes
The device is used for the removal/vaporization/ablation of soft tissue and for coagulation, which are therapeutic interventions.

No
The device is used for removing/vaporization/ablation of soft tissue and coagulation, which are therapeutic procedures, not diagnostic ones.

No

The device description explicitly states it is an electrosurgical device made of physical materials (stainless steel, teflon, etc.) and includes electrodes, indicating it is a hardware device.

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

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body (like blood, urine, or tissue) to detect diseases, conditions, or infections.
  • Device Function: The description clearly states the device is an "electrosurgical device" used for "removing/vaporization/ablation of soft tissue" and "coagulation" on anatomical sites like the prostate or myomas. This is a surgical procedure performed directly on the patient's body, not a test on a sample outside the body.

The information provided describes a surgical tool, not a diagnostic test.

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

Devices were tested to meet the appropriate sections of the ANSI/AAMI standard on High Frequency Devices.

Using Canine Models, it has been shown that coagulation depth increases with higher wattage but does not exceed 2-3mm. Irrigation reduces the risk of heat damage. Long term morbidity and healing were not known.
