Abstract
This invention provides a method and an apparatus for selectively heating a resistive mass which partially or fully occludes a particular tubal passage, such as a blood vessel or the urethra. As a result, the tubal passage is effectively softened or weakened, allowing the tubal passage to be more readily recanalized by expansion of a balloon or other dilatation means. This invention also provides a method and an apparatus for effectively boring through a partially or fully occluded tubal passage 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 passage.
