Abstract

The invention concerns an active electrode for the treatment of tumours or other affections using hyperthermia induced by radio frequency. The active electrode (11) is made of a material such as conductive ceramic or graphite (12), positioned in a distal end of a catheter body. The electrode is connected to a radio frequency generator and has at least one longitudinal duct continuing into a corresponding duct in the body of the catheter to allow the passage of a guide wire or arbour.
