No other RF system available offers the combination of temperature feedback along with a probe that can be easily and securely placed.

The Importance of Temperature Feedback
With the RITA System, thermocouples within the device array monitor temperatures in the ablation zone, and power is automatically adjusted so that target tissue temperatures remain constant. Dynamic, real-time temperature readouts let the user know exactly when and where target temperatures have been achieved. An internal power adjustment feature automatically maintains these at a constant level, thus assuring that sufficient heating is taking place while avoiding the delivery of excessive energy which can jeopardize the creation of a complete ablation. Additionally, temperature feedback provides post-ablation confirmation that appropriate temperatures have been reached.

The RITA System has the flexibility to permit manual temperature adjustment. Most physicians agree that the temperature information and automatic temperature control ablation process provide superior information and control of the ablation both during and after the procedure.

The RITA Array
The unique, patented array configuration of the RITA device allows the user to precisely and securely place the probe into the target tissue. Additionally, the RITA single needle technology and space-filling array provides both the security of placement that a multi-electrode configuration allows, as well as the ability to maneuver and clearly visualize where each electrode tip is located. To give the user an added level of control, the RITA arrays may be only partially deployed for instances when adjustment of the ablation size is desired. The RITA device may also be used to ablate the needle track after the procedure is complete. Please see our Product section for more information.

Ease of Use
Setting up the RITA System is simple, straightforward, and can usually be accomplished within 5-10 minutes by any member of the OR staff. Once set up, operation of the generator is simple and intuitive, and device placement is easy. Current users have also found the RITA System to be time and cost effective.

The RITA System is for use in percutaneous, laparoscopic, or intraoperative coagulation and ablation of soft tissue, including the partial or complete ablation of non-resectable liver lesions. The procedure is also used as a pain relief method in patients with metastatic bone lesions who have failed or are poor candidates for standard pain therapy.

The adverse event rate for RFA is low with most of the complications being considered minor. The following complications (in alphabetical order) have been associated with electrosurgical ablation procedures in liver and bone metastases; abscess, bleeding/local hematoma, bone fracture, cardiac arrhythmia, fever, fistula, injury to adjacent structures (bile duct, nerves), liver dysfunction and death, pneumothorax (asymptomatic), procedural discomfort (abdominal pain), and skin burn.
