A balloon catheter for canalizing occluded blood vessels comprising a catheter tube (1), a longitudinally extending balloon unit (2) having a longitudinally extending cylindrical section (10) and two end sections (11, 12). The invention is characterized by heat insulating means (13-16) provided at the end sections (11, 12) of the balloon unit as well as by the fact that the cylindrical section (10) is manufactured of heat-conducting material. Hot liquid, possible with the addition of X-ray contrast material, is introduced through said lumen to the internal space enabling the wall surface of a blood vessel (6) to be exposed to thermal action. |
