Abstract

A radiofrequency thermal balloon catheter makes it possible to heat uniformly the tissues in contact with the balloon and to achieve thermotherapy such as ablation or hyperthermia safely and properly for a diseased part. A radiofrequency thermal balloon catheter includes a catheter (4) consisting of an outer shaft (2) and an inner shaft (3) extended through the outer shaft so as to be slidable relative to the outer shaft, an inflatable balloon (6) capable of being inflated so as to be in contact with a target lesion (18) and equipped between respective front end parts of the outer and the inner shaft, a radiofrequency electrode (8) extended in a wall of the balloon or inside the balloon to be used for radiofrequency energy supply in combination with a counter electrode (53), the counter electrode being disposed at a predetermined position, for example, inside the balloon, in the wall of the balloon, in the position neighboring the balloon or on the patient's body surface, a lead wire (10) electrically connected to the radiofrequency electrode, a temperature sensor (12) capable of sensing temperature of a liquid contained in the balloon, and a temperature distribution uniformizing means such as a revolving structure (14) for uniformizing temperature distribution in the liquid contained in the balloon.
