Abstract

The VIVARF system (STARmed; Korea) became available in Japan in 2015. This system has an internally cooled electrode in which we can change the length of the active tip from 0.5 cm to 3 cm. We therefore performed experimental and clinical tests. At first the electrode tip appeared too hyperechogenic. After two improvements, however, the visibility of the electrode became comparable to a conventional internally cooled electrode. Its efficacy and safety seemed comparable to a conventional electrode in clinical cases. This new adjustable RF electrode is more cost-effective in some cases and may have more potential than fixed tip electrodes.
