Claim Text:
1. A trans-esophageal ablation device for ablating tissue within a patient, comprising: a flexible, elongate portion adapted to be guided within said patient; a source of energy; a two-dimensional array of transducer elements operatively coupled to said elongate portion and said source of energy, said two-dimensional array of transducer elements configured to deliver high intensity focused ultrasound (HIFU) energy to a focus zone within said patient and which may also deliver HIFU energy to a grating lobe; wherein each of said transducer elements are selectively actuatable to allow for electronic steering of said HIFU energy; and wherein said transducer elements have a taper wherein said transducer elements positioned more centrally in said two-dimensional array are larger than said transducer elements positioned more peripherally in said two-dimensional array.
