Abstract: A medical system having a medical tool, including a handle, a shaft extending from the handle and defining a lumen, a wire attached to and extending from the handle through the lumen, expandable elements at a distal end of the wire. An electrical generator is coupled to a proximal end of the wire and supplies a first waveform to the wire and the expandable elements as the expandable elements expand from an unexpanded state to an expanded state within a tissue. The electrical generator supplies a second waveform to the wire and the expandable elements when the expandable elements are in the expanded state within the tissue. The first waveform cuts tissue, the second waveform ablates tissue using radiofrequency ablation or irreversible electroporation.
