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.
Claims15
A method of performing an ablation procedure within a patient, comprising:
- placing a fiduciary marker in the patient;
- then
- acquiring a three-dimensional image of a portion of the patient using an imaging device, the three-dimensional image including the fiduciary marker;
- then
- registering the three-dimensional image to the patient using the fiduciary marker to obtain a registered three-dimensional image;
- then
- guiding a portion of an ablation device comprising a sensor into a desired position within the patient while viewing the registered three-dimensional image using a guidance device, the guidance device displaying a current position of the sensor;
- then
- energizing the ablation device to ablate tissue;
- performing the ablation procedure within the patient;
- wherein the fiduciary marker is positioned subcutaneously.
