Liver Radiofrequency ablation (RFA) is a treatment that use image guidance to place a needle through the skin into a liver tumor. In RFA, high-frequency electrical currents are passed through an electrode in the needle, creating a small region of heat. The heat destroys the liver cancer cells.
The VIVA RF Generator is designed to create the predictable and consistent ablation zone by using the optimized ablation modes for various nodules. It also has convenient and useful functions including to the easy operation structure and smart user interface to provide the exact information related to procedure details which is able to be translated to computer for recording patient treatment data.

It also has convenient and useful functions including to the easy operation structure and smart User Interface to provide the exact information related to procedure details which is able to be translated to computer for recording patient treatment data.
Read MoreOctopus RF electrodes are designed three kinds of active tips, which ablate lesions that are larger than 3cm in a single procedure. Octopus RF electrodes offers design for radiofrequency thermal coagulation diameter and RF parameters; enable each component of ablation size zone is used by one of the electrodes in less than 2cm local tissue heating, using two of the electrodes in measuring 2cm to 3cm local tissue, and using three of the electrodes in larger than 3cm of the local tissue heating.
Read MoreThe star RF electrodes of fixed type are intended to be used in percutaneous, intraoperative and laparoscopic approaches in radiofrequency ablation procedures. Coolant circulation system of electrode maintains suitable impedance at the surface of electrode. It also prevents tissue adjacent to active tip from charring and helps to make a spherical ablation zone.
Read MoreThe VIVA RF electrode is single electrode which is designed to be used in multiple nodules. Traditional single electrodes make the fixed ablation volume, but it is able to make the varisized ablation volume by adjusting an active tip.
