1. A tissue extraction system, comprising:
a hysteroscope including a handle coupled to an elongate shaft, the hysteroscope having a working channel and one or more fluid channels extending through the elongate shaft;
a resection device including an elongated shaft assembly configured to extend through the working channel, the elongated shaft assembly including an outer sleeve having a tissue-receiving window through a side wall of the outer sleeve into a lumen of the outer sleeve, and an inner sleeve slidably disposed within the lumen of the outer sleeve and configured to resect tissue extending through the tissue-receiving window into the lumen of the outer sleeve by sliding the inner sleeve axially relative to the outer sleeve from a window open configuration to a window closed configuration; and
a fluid management system including a pump configured to supply an inflow fluid through the hysteroscope, wherein the fluid management system includes a negative pressure source in fluid communication with the inner sleeve and configured to extract resected tissue therethrough;
wherein the inner sleeve includes an electrode element disposed at least partially within the inner sleeve and extending distally therefrom.
