    摘要: Various exemplary methods and devices (10, 110, 210) for delivering liquid therapeutic agents in solid tumors are provided. In general, a delivery device configured to deliver a liquid therapeutic agent into a solid tumor or other soft tissue can be configured to compress tissue and seal any fluid gaps around the delivery device during the delivery of the liquid therapeutic agent. In an exemplary embodiment the delivery device includes three elongate tubular shafts (12, 14, 16, 112, 114, 116, 212, 214, 216) configured to move longitudinally relative to one another. The elongate tubular shafts are configured to cooperate with one another to deliver the liquid therapeutic agent through a passageway of the delivery device to the solid tumor or other soft tissue and seal any fluid gaps around the delivery device while the liquid therapeutic agent is delivered into the solid tumor or other soft tissue.
