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: A device for directing energy to a target volume of tissue includes an inner conductor having a length and an outer conductor coaxially surrounding the inner conductor along the length. The outer conductor has a proximal portion and a distal portion. The distal portion of the outer conductor is provided with a number of apertures N defined therein for radiating energy, where N is an integer greater than 1, each aperture having a size and extending at an angle relative to a longitudinal axis of the outer conductor. At least one of the size and the angle of each aperture is varied in relation to the other apertures N−1 such that the energy radiated along the distal portion is substantially uniform.
