Abstract: A method for treating a sinus cavity is provided. The method includes the steps of inserting a plasma applicator into a sinus cavity defined in a bone mass, positioning the plasma applicator adjacent a tissue formation, generating a selectively reactive plasma effluent at the plasma applicator and directing the selectively reactive plasma effluent at the tissue formation. The selective nature of the reactive plasma enables treatment of specific targets inside the sinus while minimizing the effect on other tissues. Such treatment includes, but not limited to, sterilization of bacterial colonies, vaporization of unwanted tissues or foreign masses, stimulation of tissues by enriching the content of reactive oxygen and nitrous oxide pathways, and combinations thereof.

Abstract: An electrosurgical generator includes an electrosurgical energy output configured to deliver electrosurgical energy to a bipolar end effector assembly in a conductive fluid environment for treating tissue. A controller having a processor is configured to control a waveform of the electrosurgical energy such that the waveform oscillates between a cut phase for initiating and sustaining tissue cutting, wherein the waveform includes a cut energy greater than the energy needed to create and sustain arcing, and a hemostasis phase, for desiccating/coagulating tissue, wherein the waveform includes a hemostasis energy less than the energy needed to sustain arcing.

Abstract: A morcellation system includes a morcellator and a grasper. The morcellator includes a housing and a tube extending from the housing and having at least one blade section. The morcellator further includes an oscillating mechanism configured to oscillate the tube. An end cap is coupled to the proximal end of the housing and is configured to receive the tube. The end cap defines a passage and includes an aligning structure disposed in the passage. The grasper includes a tubular member having a grasping end including first and second jaws moveable relative to one another. The grasper further includes a handle assembly operatively associated with the grasping end. A keyed collar is disposed about the tubular member. The keyed collar includes a key configured to cooperate with the aligning structure of the end cap to align the first and second jaws relative to the distal end of the tube.

Abstract: An end effector assembly of a surgical device for shallow depth ablation includes first and second jaw members movable between open and closed positions and including hemicylindrical surfaces that cooperate to define a cylindrical cavity in the closed position for capturing tissue therebetween. At least one electrode array includes a plurality of first and second electrode portions disposed on or within at least one of the hemicylindrical surfaces and extending annularly at least partially thereabout. The plurality of first and second electrode portions are configured to be energized with electrosurgical energy at different potentials to thereby conduct electrosurgical energy between adjacent first and second electrode portions and through captured tissue to affect shallow depth ablation of captured tissue in the closed position of the first and second jaw members.
