1. An apparatus for thermally treating tissue, comprising:

  • an elongate introducer having a proximal end, a distal end, and an interior passageway extending from the proximal end to an opening in the distal end;

    a flowable insulative material carried in or otherwise in fluid communication with the interior passageway;

    at least one electrode coupled to or proximate to the distal end of the introducer;

    an energy delivery actuator configured to controllably energize the at least one electrode; and

    a flow actuator configured to actuate a controlled flow of the flowable insulative material from the interior passageway through the distal end opening and outwardly from the distal end of the introducer;

    wherein the flowable insulative material comprises a base polymer and dispersed nonconductive filler.
