The steerable catheter comprises a flexible tube, inside of which different conducts are arranged: one or more conducts for drug administration, vacuum conducts associated with different radiofrequency electrodes, conducts for the conductive wires that conducts the radiofrequency energy to the distal end of the catheter, conducts for the fibre optic cable/s that conducts the laser energy to the distal end of the catheter, a guiding wire for the catherization, and another components the steerable catheter being connected from the proximal end to a energy unit and other pressure and/or dosing devices and the steerable catheter optionally including an inflatable balloon to help occluding the vessel and it also incorporates one or two electrode/s or conductive layer/s in the distal end of the catheter the objective of the steerable catheter being the obtaining of better results in the embolization and/or chemoembolization treatments.
