A method of ablating tissue in the heart to treat atrial fibrillation introduces into a selected atrium an energy emitting element. The method exposes the element to a region of the atrial wall and applies ablating energy to the element to thermally destroy tissue. The method forms a convoluted lesion...http://www.google.es/patents/US7413568?utm_source=gb-gplus-sharePatente US7413568 - Composite structures and methods for ablating tissue to form complex lesion patterns in the treatment of cardiac conditions and the like
