1. An ablation device for ablating tissue within a patient, comprising:
- a two-dimensional array of transducer elements including a plurality of transducer elements, the two-dimensional array of transducer elements configured to deliver high intensity focused ultrasound (HIFU) energy, wherein the transducer elements have a taper and further wherein the transducer elements positioned more centrally in the two-dimensional array are larger than the transducer elements positioned more peripherally in the two-dimensional array.

Abstract
A device and method for ablating tissue is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding an ablating member within the patient while tracking the position of the ablating member in the patient, positioning the ablating member in a desired position to ablate tissue, emitting ablating energy from the ablating member to form an ablated tissue area and removing the ablating member from the patient.
