1. A cell necrosis apparatus for delivering thermal microwave energy to a specific site in a body, comprising:

  • a. a microwave generator, b. a coolant delivery system for delivering and circulating a quantity of cooled liquid coolant via inlet and return passageways, c. a probe comprising a probe handle and a probe body having a proximal portion coupled to said probe handle and a distal portion, d. a microwave antenna in said distal portion of said probe body for applying thermal microwave energy to said specific site in cell necrosis treatment, and e. a microwave transmission line extending from said microwave generator to and through said probe handle and to and through said probe body to said microwave antenna and electrically coupled thereto, f. said inlet and return coolant flow passageways extending from said coolant delivery system to and through said probe handle and thence extending coaxially about said antenna and along the length thereof within said probe body, where a first of said inlet and return coolant flow passageways is radially outward of and immediately adjacent said microwave transmission line and said antenna within said probe body and the other of said inlet flow passageways is radially outward of said first flow passageway.
