The description focuses on the hardware components and their functions in delivering RF energy for ablation, with no mention of AI or ML capabilities for analysis, decision-making, or control.
Yes
The device is indicated for the coagulation and ablation of soft tissue, including the partial or complete ablation of non-resectable liver lesions and the palliation of pain associated with metastatic lesions involving bone, which are therapeutic applications.
No
The RITA® System supplies energy for electrosurgery and is indicated for the coagulation and ablation of soft tissue, not for diagnostic purposes.
No
The device description clearly lists multiple hardware components including an RF Generator, Disposable Electrode, Infusion Pump, Tubing Kit, Main Cable, Dispersive Electrode, Power Cord, and Foot Pedal.
Based on the provided information, the RITA® System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the RITA System is used for "percutaneous, laparoscopic, or intraoperative coagulation and ablation of soft tissue." This involves direct intervention on the patient's body to treat conditions.
- Device Description: The components described (RF generator, electrodes, pump, cables, etc.) are all designed to deliver energy and perform a physical procedure on the patient.
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens (like blood, tissue, or urine) outside of the body to provide diagnostic information. IVDs are used to diagnose diseases or conditions based on the analysis of such specimens.
In summary, the RITA System is a therapeutic device used for surgical procedures, not a diagnostic device used for analyzing samples in a lab setting.

Intended Use / Indications for Use
The RITA® System (RF generator and electrosurgical devices) supplies energy for use in electrosurgery and is indicated for use in percutaneous, laparoscopic, or intraoperative coagulation and ablation of soft tissue, including the partial or complete ablation of non-resectable liver lesions and the palliation of pain associated with metastatic lesions involving bone in patients who have failed or are not candidates for standard pain therapy.

Device Description
The RITA System consists of the following components:
RF Generator: Provides RF energy to the Device through the Main Cable.
Disposable Electrode ("the Device"): Consists of a number of deployable electrodes. Some or all are equipped with a thermocouple, depending on the model of the Device. Some Devices are used with saline infusion ("Infusion Devices") and require the use of a pump.
Infusion Pump: When using the RF Generator with the Infusion Devices, an off-the-shelf market-cleared infusion pump or a RITA Pump is used to deliver saline through the Infusion Device during ablation. In the off-the-shelf pump, syringes are connected to the Infusion Device and loaded into the Infusion Pump. In the RITA Pump, a Tubing Kit is connected to the Infusion Device and loaded into the RITA Pump. The RF Generator is connected to the Infusion Pump via an RS-232 cable.
Tubing Kit: The tubing kit is designed to load into the pump head from the front of the pump. On the proximal end of the tubing-set there is a PVC Bag Spike fitting that allows the tubing to be attached to an IV bag. The Bag Spike fitting is attached to a single length of tubing that is connected to a splitter fitting that splits the single tubing into 5 separate tubes. The 5 tubes are held together with clips that allow the tubes to be uniformly loaded into the pump head. The distal end on the tubing-set has 5 female luers to attach to the Infusible devices.
Main Cable: Connects the Device to the RF Generator.
Dispersive Electrode: Provides the return path for the RF energy applied by the Device. Depending on the model, the dispersive electrode may be equipped with thermocouples to measure skin temperature at the dispersive pad. Dispersive pads with temperature sensing capabilities are connected to the RF Generator at the dispersive electrode connection and at the Aux port.
Power Cord: A medical grade line cord that provides AC power to the RF Generator.
Foot Pedal: The Foot Pedal is connected to the front of the RF Generator. The Foot Pedal starts and stops the RF energy delivery when the RF Generator is in "READY" mode.
To use the system, the RF Generator is plugged into the wall outlet via the Power Cord. The electrosurgical device is connected to the RF Generator via the Main Cable. The Dispersive Electrode is placed on the appropriate location of the body and is connected to its port on the RF Generator. If a pump is used, it is connected to scrial port B of the RF Generator. Once the system is successfully powered up, the user can set the parameters of the ablation such as the mode of operation, the ablation time, the target temperature, and the power delivery level. One mode of operation, purge, is used to communicate with an infusion pump to prime the system. There are four modes of operation for RF energy delivery: constant power, constant temperature, infusion mode, and track ablation. In the infusion mode, the RF Generator communicates with the infusion pump to set and adjust the infusion With the electrosurgical device placed in the tissue to be ablated and its rate. electrodes deployed, RF power can be turned on. The system parameters are continuously monitored and displayed on the RF Generator. If the measured parameters arc outside the acceptable limits, the RF energy delivery and fluid delivery (if in infusion mode) automatically stops and a message appears on the liquid crystal display (LCD). The RF energy delivery and fluid delivery (if in infusion mode) also automatically ceases once the ablation is completed based on the initial user-defined parameters. RF energy can also be stopped at any point by pressing the RF on/off switch. Fluid delivery can also be stopped at any point by pressing the pump on/off switch.
