    Abstract: A kit for delivering microwave ablative energy to tissue and methods for using the kit are included. The kit includes an access catheter, an implant deployment tool, and a microwave delivery device. The implant deployment tool is configured to be inserted into the access cathether and has an implant disposed therein in a contracted state and being slidable out of a distal opening and expandable into an expanded state. The microwave delivery device is configured to deliver the microwave ablative energy to the tissue and to be advanced through the access catheter and slidably disposable within the implant when the implant is in the expanded state.

    Abstract: An electrosurgical system includes an energy applicator adapted to direct energy to tissue, an electrosurgical power generating source, and a surface-contact detection device. The surface-contact detection device is operably associated with the energy applicator. The surface-contact detection device is communicatively-coupled to the electrosurgical power generating source. The surface-contact detection device includes at least one optical transmitter to generate optical signals, a lens member configured to reflect optical signals generated by the optical transmitter when the lens member is disposed in contact with tissue, and at least one optical receiver to receive optical signals reflected by the lens member. The electrosurgical power generating source is adapted to transmit energy to the energy applicator when it is determined that the lens member is disposed in contact with tissue.

    Abstract: A microwave ablation system includes a generator operable to output energy and an ablation probe coupled to the generator that delivers the energy to a tissue region. The ablation system also includes a controller operable to control the generator and at least one sensor coupled to the ablation probe and the controller that detects an operating parameter of the ablation probe. The controller performs a system check by ramping up an energy output of the generator from a low energy level to a high energy level and monitors an output from the sensor at predetermined intervals of time during the system check to determine an abnormal state. The controller controls the generator to cease the energy output when the controller determines an abnormal state.

    Abstract: A surgical instrument is configured to concurrently dissect and coagulate tissue. The surgical instrument includes a handle and a shaft extending distally from the handle. The shaft includes an outer hypotube, a lumen coaxially-disposed within the hypotube and extending beyond a distal end thereof, a coaxial feedline coaxially-disposed within the lumen, and having an inner conductor and an outer conductor disposed coaxially about the inner conductor, and a coolant tube coaxially-disposed between the lumen and the coaxial feedline to form an inflow conduit and an outflow conduit. The instrument further includes a dissecting head assembly coupled to a distal end of the shaft. The dissecting head assembly includes a dielectric core having a substantially planar radiating surface and at least one non-radiating surface, a reflective coating disposed on the at least one non-radiating surface of the dielectric core, and a blade extending from the radiating surface.
