| abstract |
The invention concerns a catheter for the treatment of tumours and other affections using hyperthermia induced by radio frequency, which comprises a tubular body (10) with or without anchoring balloon at its distal end, an active electrode (16) positioned around said body and connected to a radio frequency generator, and at least one thermistor needle (19) to measure the temperature around said electrode. The active electrode (16) is flexible and connectable to a supply source of a fluid for cooling the electrode. It includes a helical conduit (21, 25) which can be metal, conductive ceramic or graphite. |
