1. A device for ablating tissue, the device comprising:
- a first probe including a first contact surface, said first contact surface having a first surface area configured to contact tissue, and a first ablating element on said first contact surface, said first ablating element having a second surface area less than said first surface area;
a second probe including a second contact surface, said second contact surface having a third surface area configured to contact tissue, and a second ablating element on said second contact surface, said second ablating element having a fourth surface area less than said third surface area, wherein said first and second ablating elements are operable to be brought into substantially opposing relation; and
a control system coupled to said first and second ablating elements, wherein said control system comprises a processor configured to monitor ablation progress and a controller configured to control at least one of said first and second ablating elements in response to at least one output of said processor.

7. A device for ablating tissue, comprising:
-
a flexible probe including at least one ablating element extending over a portion of said flexible probe; and
a cover extending over at least a portion of said at least one ablating element, wherein said cover insulates the tissue from said at least one ablating element when said cover is in an unretracted position, and wherein said at least one ablating element is exposed to the tissue when said cover is in a retracted position.
