Ablation device with drug delivery component

ABLATION DEVICE WITH DRUG DELIVERY COMPONENT An ablation system (200) includes a source of electrosurgical energy (28), a source of coolant fluid (48), and an ablation electrode assembly (110) operatively connected to the source of electrosurgical energy (28) and fluidly-coupled to the source of coolant fluid (48). The ablation electrode assembly (110) includes a hub (130) defining a chamber (132) therein and one or more electrically-conductive ablation needles (112) extending from the hub (130). The ablation system (200) also includes one or more delivery needles (401) extending from the hub (130). The one or more delivery needles (401) are selectively moveable from a first position, wherein the distal end of the delivery needle (401) is disposed proximal to the distal end portion of the ablation needle 112), to at least a second position, wherein at least the distal end of the delivery needle (401) is disposed distally beyond the distal end portion of the ablation needle (112). -100 130 136 11 2 120 114 118 -, 22 7- 124a "TC"1 118a /144 1 4116 142 {179 13412 "F" -o- 101 136 132 122 11412 ) |118 /v I 124a -,,, 7, 7777, -118 a 134 11Fl 1 124 1 16 124b
