Abstract
A method of creating a lesion in cardiac tissue where the method includes deploying a distal treatment section of an ablation catheter into a heart chamber and manipulating the distal treatment section against the cardiac tissue and into a curved shape that encloses a plurality of vessel entries in the heart chamber. The method further includes commencing a first application of ablation energy from the distal treatment section to the cardiac tissue and halting the first application of ablation energy to the cardiac tissue. The first application of ablation energy causes formation of a first continuous lesion in the cardiac tissue that encloses the plurality of vessel entries.
