Abstract:
1. A method of thermally treating tissue in a body, comprising: selecting a targeted portion of a tissue structure to be ablated using transmitted energy; identifying a nearby insulation portion of tissue to be insulated from the transmitted energy; introducing a flowable material into a delivery lumen of an elongate introducer, such that the flowable material flows through the delivery lumen, exits out a distal opening of the elongate introducer, and is deposited onto the insulation portion of tissue, thereby forming an insulative layer on the insulation portion of tissue; electrically coupling a radiofrequency (RF) energy source to a conductive liquid or gel electrode contacting the targeted portion of the tissue structure; transmitting RF energy from the RF energy source to the targeted portion of the tissue structure via the conductive liquid or gel electrode to thereby treat at least a portion of the targeted portion of the tissue structure.
