Abstract: Tissue cutting systems and methods of tissue cutting are provided. In one example, the tissue cutting system includes a first device and a second device adapted for coupling to a power supply. The first device includes a conductive probe. The second device includes a conductive material, for example, as part of an expandable structure, having an outer surface area of conductive material that may be larger than a surface area of the conductive probe. The conductive probe and the conductive material are deployed along opposite sides of a body tissue, such as an aortic dissection flap. Selective electrical power is applied to the conductive probe and the conductive material to cut the body tissue.
