Claim:
1. An electrosurgical system for resecting and extracting tissue, said system comprising: an elongated probe including an inner sleeve which includes a first polarity electrode and defines a tissue extraction lumen therein, and an outer sleeve which includes a second polarity electrode; wherein the first polarity electrode is disposed at a distal end of the inner sleeve and is movable therewith, wherein movement of the first polarity electrode is dependent upon movement of the inner sleeve; wherein the inner sleeve reciprocates within the outer sleeve, and wherein the elongate probe is configured to operate in a first mode wherein the inner sleeve is advanced to resect and capture tissue and in a second mode wherein a fluid volume within the outer sleeve is vaporized by application of RF energy between the first and second polarity electrodes in order to expel tissue captured by operating in the first mode.
