First Claim
Patent Images
1. A method of performing an ablation procedure within a patient, the method comprising:
- acquiring an image of an anatomy of interest of the patient;
correlating the image with the patient'"'"'s anatomy using an image guidance system;
guiding an ablation device to an energy delivery location within the patient, the ablation device comprising a high intensity focused ultrasound (HIFU) emitting member and one or more image guidance sensors for tracking a position of the ablation device within the patient;
emitting ultrasound energy from the HIFU emitting member into a target area of tissue disposed a distance from the energy delivery location, the ultrasound energy being focused into one or more focusing zones within the target area of tissue; and
heating the target area of tissue generally within the focusing zones to form ablation lesions in the target area of tissue.

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.
