The handle (30) includes a housing (32) having a proximal end and a distal end, a hub (34) included within the housing (32) having a plenum (42) defined therein, and a proximal feedline (70) in fluid communication at a proximal end thereof with the plenum (42) and joined at a distal end thereof to a first coupling member (24). The ablation probe (20) includes a probe hypotube (81) shaft having a proximal end and a distal end, a second coupling member (22) disposed at a proximal end of the probe hypotube (81) shaft adapted to operably couple with the first coupling member (24), a distal tip (21) adapted to penetrate tissue. Ablation energy is deliverable by the ablation probe (20) when the source of ablation energy (14) is operably coupled to the handle (30) and the handle (30) is operably coupled to the ablation probe (20).1/15 21/ <;10 20 18 COOLANT 16 23 12 23 15 - - -31 14 GENERATOR FIG.1
