Abstract: A drug-delivery cannula assembly includes a cannula housing adapted for receiving at least one obturator shaft of an obturator assembly therethrough, one or more cannulae, and a supply line coupled to the cannula housing. The cannula housing is adapted for receiving one or more obturator shafts of an obturator assembly therethrough. The one or more cannulae define a longitudinal axis and a passageway aligned with the longitudinal axis. The one or more cannulae each include a proximal end coupled to the cannula housing. The cannula housing is configured to fluidly-couple the one or more cannulae to a source of a drug delivery supply for supplying drugs via the supply line to the one or more cannulae.

Abstract: A drug-delivery device includes a body configured for attachment to a handle of an ablation device, a shaft portion defining a passageway therein, and a delivery lumen to provide for drug delivery to tissue. The body includes a proximal portion, a distal portion, and a contoured portion disposed therebetween. The contoured portion is configured for engagement with a contoured portion of the handle of the ablation device. The shaft portion includes a proximal end and a distal end. The proximal end of the shaft engages with an opening defined in the distal end of the body. The passageway of the shaft portion is configured to receive the delivery lumen slideably moveably therein. The delivery lumen includes a proximal portion and a distal portion. The drug-delivery device also includes a knob member coupled to the proximal portion of the delivery lumen.

Abstract: 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.
