Claim 17:
18. A medical device system, the medical device system comprising:
a tissue resecting device comprising:
an outer sleeve and an inner sleeve, the outer sleeve including a distal window disposed proximate a distal end of the outer sleeve, wherein the inner sleeve has an outer surface having a first diameter,
an electrode element disposed proximate a distal end of the inner sleeve, wherein the electrode element has an outer surface having a second diameter less than the first diameter, and
an insulative layer bonded to the inner sleeve and insulating the inner sleeve from the outer sleeve,
wherein the insulative layer extends distally beyond the distal end of the inner sleeve and covers at least a portion of the electrode element;
wherein the insulative layer is bonded directly to the outer surface of the electrode element having the second diameter,
wherein the insulative layer is configured to peel away from the inner sleeve when the tissue resecting device is used to resect uterine fibroids, thereby resulting in the tissue resecting device becoming non-operational;
a motor for reciprocating the inner sleeve relative to the outer sleeve; and

an RF generator for delivering energy through the electrode element to resect tissue.
