1. A method of resecting tissue, comprising:
advancing a tissue resecting device to a treatment site, the tissue resecting device comprising:
an outer sleeve including a side window opening into a lumen of the outer sleeve and a tissue engagement member extending proximally from a distal tip of the outer sleeve within the lumen, the outer sleeve including a first electrode having a first polarity; and
an inner sleeve positioned in the lumen of the outer sleeve, the inner sleeve including a tubular shaft and a second electrode at a distal end of the tubular shaft, the second electrode having a second polarity opposite the first electrode;
longitudinally reciprocating the inner sleeve relative to the outer sleeve such that the second electrode repeatedly moves across the side window from a proximal position to a distal position and back to the proximal position from the distal position, wherein in the distal position the second electrode extends distal of a proximal end of the tissue engagement member; and
applying an RF current between the first electrode and the second electrode as the second electrode moves across the side window from the proximal position to the distal position.
