Focused ultrasound ablation devices having selectively actuatable emitting elements and methods of using the same
First Claim
1. A focused ultrasound ablation device for creating a lesion in tissue of a patient comprising:
- an ultrasound emitting member having a plurality of individual ultrasound emitting elements spaced from one another, the ultrasound emitting elements being actuatable to emit ultrasound energy a predetermined distance outwardly from an active surface whereby the ultrasound energy is focused within tissue of the patient at separate and distinct locations for each individual ultrasound emitting element to form a lesion, the ultrasound emitting elements being selectively, independently actuatable to emit ultrasound energy and being selectively, independently non-actuatable to not emit ultrasound energy whereby a lesion of selected size and configuration is formed in accordance with the positions of the ultrasound emitting elements selected to be actuated; and
a handle coupled to said ultrasound emitting member.

Abstract
A focused ultrasound ablation device and method includes an ultrasound emitting member having a plurality of individual ultrasound emitting elements arranged in an array. The ultrasound emitting elements are actuatable to emit ultrasound energy and focus the emitted ultrasound energy a predetermined distance from the ultrasound emitting member such that the ultrasound energy is focused within anatomical tissue adjacent which the ultrasound emitting member is positioned. The anatomical tissue is heated by the ultrasound energy focused therein to form an internal lesion within the tissue. The ultrasound emitting elements are selectively, independently actuatable, allowing selected ones of the ultrasound emitting elements to be actuated to emit ultrasound energy to obtain a lesion of desired or selected size and/or surface configuration in the tissue of a particular patient.
