1. An ablation apparatus for creating a lesion in target tissue, the ablation apparatus comprising:
a handle;
a flexible elongate shaft extending from the handle to a distal tip, the shaft comprising:
a first portion;
an ablation portion distal to the first portion; and
at least one ablation energy element disposed along the ablation portion, wherein a space is formed between each of the at least one ablation energy elements; and
a solid thermally conductive liner disposed within the space and arranged to cover only a portion of the perimeter of each of the at least one ablation energy elements, and defining an uncovered portion of the perimeter of each of the at least one ablation energy elements, and
wherein the thermally conductive liner comprises a thermoplastic elastomer (TPE) loaded with a thermally conducting material, and
wherein the thermally conductive liner is loaded with the thermally conducting material sufficient to provide thermal conduction therethrough.
