Abstract:
1. An ablation probe, comprising: a feedline having an outer sheath, an inner conductor, and an insulator coaxially disposed around the inner conductor, wherein the inner conductor extends distally beyond the outer sheath and the insulator; a hypotube coaxially disposed around the feedline having two longitudinal ribs that extend radially inward from an inner surface of the hypotube to an outer surface of the feedline to define an inflow fluid channel and an outflow fluid channel; a feed point seal operably coupled to a distal end of the hypotube and including a first opening and a second opening defined therethrough, each having a proximal end and a distal end, wherein the proximal end of the first opening is disposed in fluid communication with the inflow fluid channel and the proximal end of the second opening is disposed in fluid communication with the outflow fluid channel; a distal radiating section having a cylindrical outer dielectric surface, and a generally conical tip disposed at a distal end of the distal radiating section, the cylindrical outer dielectric surface and conical tip defining a cooling region therein; and a porous core closed within the cooling region and in fluid communication with the distal end of the first opening of the feed point seal and the distal end of the second opening of the feed point seal.
