    Abstract: An energy delivery device cooling system includes a reservoir connector assembly and an elongate member. The elongate member has first and second lumens in fluid communication with the reservoir. The first lumen includes an outflow port and the second lumen includes a return port each in fluid communication with the reservoir. The device further includes a tubing system having a first end and a second end. The first end connected in fluid communication with the outflow port and the second end in fluid communication with the return port. The second end configured to return a fluid to the reservoir. The tubing system connects to an energy delivery device to cool the fluid.

    Abstract: A microwave ablation system includes a first cannula, a trocar insertable through the first cannula and configured to facilitate insertion of the first cannula into a target tissue, and a microwave antenna assembly configured to interlock with the first cannula, the microwave antenna assembly including a coaxial feedline having a radiating section formed thereon, the microwave antenna configured to be inserted into the first cannula. The microwave ablation system further includes an actuator operatively connected to one of the first cannula or microwave antenna assembly. Operation of the actuator between a first position and a second position exposes the radiating section of the microwave antenna assembly from a distal portion of the first cannula.

    Abstract: A surgical instrument for ablating tissue includes a handle portion and a shaft assembly extending distally from the handle portion. The shaft assembly includes an outer shaft, a coaxial cable extending through the outer shaft, and an electrode coupled to a distal portion of the outer shaft. The coaxial cable has a distal portion that forms a microwave antenna configured to transmit microwave energy radially outward and through the outer shaft. The electrode is configured to transmit radiofrequency energy. An actuation of the handle portion activates the transmission of the microwave energy from the microwave antenna and/or the transmission of the radiofrequency energy from the at least one electrode.
