Abstract:
An ablation tool for forming lesions in body tissue of a subject at a desired ablation site, comprising:an elongate member having a distal and proximal end;an element array disposed on the elongate member distal end, wherein said element array has two free ends;at least one energy emitting element disposed on the element array; anda source of energy coupled to the at least one energy emitting element, said source of energy capable of energizing the at least one energy emitting element to form a lesion in body tissue that is pressed against the at least one energy emitting element, wherein the elongate member and element array are sized and configured for nontransluminal placement of the at least one energy emitting element at a target site, and wherein at least one of the elongate member and element array are malleable such that they can take on a desired shape prior to positioning in the subject and substantially retain that shape as said element array is positioned in the subject at the desired ablation site, the desired shape selected so as to impart a desired lesion pattern on the body tissue at the ablation site.
