This invention provides a method and apparatus for selectively heating an atheromatous mass which partially or fully occludes a particular blood vessel. As a result, the occlusive mass is effectively softened or weakened, allowing the occlusive mass to be more readily recanalized by expansion of a balloon or other dilitation means. This invention also provides a method and apparatus for effectively boring through a partially or fully occluded blood vessel by simultaneously applying both (1) heat to the occlusive mass surrounding the tip of the catheter and (2) pressure against the mass within the partially or fully occluded blood vessel.
