Worldwide some 2 million people Heat plus saline – a patented success formula contract cancer of the liver every year. Unfortunately only around 30% of patients are suitable for surgical therapy. This has led to the development of new therapeutic strategies for the large collective of inoperable liver tumor patients. Among the most successful methods have been those involving energy application such as radiofrequency thermoablation (RFA).

Dedicated research and development in the medical field has made valuable contributions to improving treatment options for liver tumor patients. One noteworthy example of this is Highfrequency- induced thermotherapy, or HiTT for short. This form of treatment meets many patient and physician needs: a minimally invasive, effective yetorgan sparing and low-risk method for the treatment of inoperable tumors, especially of the liver.

HiTT for monopolar or bipolar radiofrequency thermoablation

Which application technique of radiofrequency ablation (RFA) is ideal in a given case depends on various factors:

• proximity of the tumor location to heat-sensitive tissues
• size and geometry of the desired tumor necrosis zone
• active and passive elements of the RF circuit

The Elektrotom HiTT 106 device system gives the physician the choice of using RFA in monopolar or bipolar technique.

Bipolar thermoablation provides substantial advantages in terms of operating safety in the case of difficult tumor locations close to heat-sensitive tissues or of insufficient image control. It makes the neutral electrode dispensable: only used if the surgeon wants to retain the option of combining the bipolar and monopolar techniques in one therapeutic session. Short current paths between the needle tips, which measure no more than 30 mm apart, focus the RF energy turnover entirely on the tumor area.
