1. A tissue heating apparatus, comprising:

  • an elongated body having proximal and distal ends;

    a first heating source disposed on the distal end of said elongated body to deliver heat to a tissue to be treated; and

    a second heating source disposed adjacent said first heating source to provide secondary heat to the tissue simultaneously as said first heating source delivers heat to the tissue;

    wherein said first heating source provides a more rapid thermal response than said second heating source and said second heating source has a higher heat capacity than said first heating source such that temperature fluctuations in said first heating source are dampened by said second heating source, and wherein said second heating source comprises an electrothermal mass.
