摘要：
An ablation system includes a source of electrosurgical energy, a source of coolant fluid, and an ablation electrode assembly operatively connected to the source of electrosurgical energy and fluidly-coupled to the source of coolant fluid. The ablation electrode assembly includes a hub defining a chamber therein and one or more electrically-conductive ablation needles extending from the hub. The ablation system also includes one or more delivery needles extending from the hub. The one or more delivery needles are selectively moveable from a first position, wherein the distal end of the delivery needle is disposed proximal to the distal end portion of the ablation needle, to at least a second position, wherein at least the distal end of the delivery needle is disposed distally beyond the distal end portion of the ablation needle.
