Intended Use
The Force Argon™ II Argon Enhanced Electrosurgical System is intended for use in both open, laparoscopic, and thoracoscopic surgical procedures (general. neurosurgical, gynecologic) where monopolar electrosurgery (cutting and coagulation) is normally used. The Force Argon™ II Argon Enhanced Electrosurgical System provides a controlled flow of argon to electrosurgical handsets during cutting and coagulation. When the handset is activated in the gas enhanced modes, an argon gas plasma is created between the electrode and the tissue.
Device Description
The Force Argon™ II Argon Enhanced Electrosurgical System is designed to provide a controlled flow of argon (an inert, non-reactive gas) to custom designed electrosurgical handsets powered by Valleylab electrosurgical generators. The handsets allows the surgeon to perform argon enhanced electrosurgery in open and laparoscopic procedures. Depending on the handpiece, the system can function in the following argon enhanced modes: - Argon Shrouded Cut Argon gas is delivered through the handset . while the attached electrosurgical generator is activated in the cut mode. - Argon Enhanced Coag Argon gas is delivered through the handset while . the generator is activated in the coag mode. The Force Argon™ II Argon Enhanced Electrosurgical System has two gas flow modes; one for laparoscopic procedures (Low Flow Mode, 0.5 - 4.0 SLPM) and one for open procedures (Standard Flow Mode, 0.5-12 SLPM). In addition, the system monitors the peritoneal pressure during laparoscopic procedures. The physician can set the desired pressure on the Force Argon™ II Argon Enhanced Electrosurgical System. When the peritoneal pressure approaches a predefined percentage of the set pressure, an alarm is activated to alert the user. A second alarm sounds when the actual peritoneal pressure reaches the set point. The physician can then vent the peritoneal cavity to relieve the pressure. The Force Argon™ Argon Enhanced Electrosurgical System is designed to allow the physician to continue to use argon enhanced electrosurgery when the peritoneal pressure set limit is reached. The Force Argon™ II unit is designed to fit on a table top or a cart. Tank holders will be offered for use with the Valleylab Gas Delivery System carts which will accommodate argon tank sizes ranging from 14 to 42 cubic feet.

No
The description focuses on controlled gas flow, electrosurgical modes, and pressure monitoring, with no mention of AI or ML technologies.

Yes
The device is used to perform argon-enhanced electrosurgery (cutting and coagulation) during surgical procedures, which directly treats tissues.

No
The device is described as an electrosurgical system intended for cutting and coagulation during surgical procedures, not for diagnosing conditions.

No

The device description explicitly details hardware components such as the Force Argon™ II unit, electrosurgical handsets, and tank holders, and the performance studies mention hardware validation and testing.

Based on the provided information, the Force Argon™ II Argon Enhanced Electrosurgical System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is for surgical procedures (open, laparoscopic, and thoracoscopic) where electrosurgery is used. This involves direct interaction with the patient's tissue during surgery.
  • Device Description: The device delivers argon gas to enhance electrosurgical cutting and coagulation. It also monitors peritoneal pressure during laparoscopic procedures. These are all actions performed on or within the patient's body during a surgical procedure.
  • Lack of IVD Characteristics: IVD devices are designed to examine specimens (like blood, urine, tissue samples) outside the body to provide information about a patient's health status, diagnose conditions, or monitor treatment. The Force Argon™ II does not perform any such analysis of specimens.

Therefore, the Force Argon™ II Argon Enhanced Electrosurgical System is a surgical device used in vivo (within the living body), not an in vitro diagnostic device.
