Ablation systems comprise a support body, an energy transmitting element supported by the support body and an insulating member covering a portion of the support body and energy transmitting member. Ablation energy is transmitted from an uncovered, exposed portion of the energy transmitting element. The insulating member may be a distal portion of an introducer sheath. An open segment may be provided in the distal portion to expose a portion of the energy transmitting element. When used in cardiac ablation therapy, for example, the insulating member decreases the amount of ablation energy dissipated in the blood circulating through the heart and thermally insulates the energy transmitting member and the tissue at the ablation site, enabling better control of the ablation process. An inflatable balloon or an expandable web may be provided coupled to the distal portion of the sheath behind the open segment to provide further insulation of the energy transmitting element and of the tissue around the ablation site. In another embodiment, ablation catheters incorporate an insulating member such as the inflatable balloon, expandable web or a cover. Methods of ablating tissue are also disclosed.
