摘要： An electrosurgical instrument comprising an end effector is disclosed. The end effector comprises a first jaw and a second jaw. The first jaw comprises a first electrode. The end effector is movable from an open configuration to a closed configuration to grasp tissue. The second jaw comprises a second electrode configured to deliver a first monopolar energy to the tissue, a third electrode, and a conductive circuit selectively transitionable between a connected configuration with the third electrode and a disconnected configuration with the third electrode. In the connected configuration, the third electrode is configured to cooperate with the first electrode to deliver bipolar energy to the tissue. The conductive circuit defines a return path for the bipolar energy. In the disconnected configuration, the first electrode is configured to deliver a second monopolar energy to the tissue.

摘要： An apparatus includes a shaft, a balloon, a tip member, and a heating feature. The tip member is distal to the balloon and has a larger outer diameter than the shaft. The heating feature is operable to ablate tissue of the Eustachian tube contacting the balloon in the expanded state. The heating feature may include an illuminating element and a photosensitive coating on the balloon. Alternatively, the heating feature may include a thermal heating element that heats the balloon inflation fluid and thereby heats the wall of the balloon. Another apparatus includes a shaft, a tip member, and an electrode assembly. The electrode assembly includes a plurality of electrodes positioned along the shaft near the distal end, proximal to the tip member. The electrodes are spaced apart from each other along a longitudinal axis and are operable to apply RF energy to tissue to thereby ablate the tissue.

The electrosurgical substrate includes an electrosurgical blade. The electrosurgical blade includes (i) a first lateral surface, (ii) a second lateral surface opposite the first lateral surface, (iii) a first major surface extending between the first lateral surface and the second lateral surface on a first side of the electrosurgical blade, and (iv) a second major surface extending between the first lateral surface and the second lateral surface on a second side of the electrosurgical blade that is opposite the first side. The monopolar electrosurgical electrode also includes a first electrode sensor embedded between a plurality of electrical insulation layers on the first major surface of the electrosurgical blade.

摘要： Various embodiments of ablation elements are disclosed herein, where the ablation element includes a biodegradable shell. Calcium chloride is retained within the biodegradable shell. When the ablation element is delivered to a target location within the body of a patent, the biodegradable shell degrades to release the calcium chloride. A reaction between the released calcium chloride and bodily fluids will generate heat, which in turn will ablate biological material in proximity to the reactive region.

摘要： A method of manufacturing a thermal cutting element for a surgical instrument includes manufacturing a substrate, coating at least a portion of the substrate via Plasma Electrolytic Oxidation (PEO), and disposing a heating element on at least a portion of the PEO-coated substrate. The method may further include attaching the thermal cutting element to a jaw member of a surgical instrument. A thermal cutting element for a jaw member of a surgical instrument includes a substrate, a PEO coating disposed on the substrate, and a heating element disposed on the PEO coating and including first and second end portions adapted to connect to different potentials of electrical energy to heat the heating element.
