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.

Claims

1. A method of performing an ablation procedure within a patient, comprising:

providing an imaging device;

acquiring an image of the patient;

providing an ablation device having one or more sensors;

guiding the ablation device into a desired position within the patient while viewing the acquired image;

performing the ablation procedure within the patient.
