A method of treatment comprising:

• folding and inserting a track into a patient's body and positioning the track adjacent a target area inside the patient's body, wherein the track unfolds to a final shape and size after being located inside the patient's body;
• anchoring the track to a tissue in the target area;
• positioning a transducer guided by the track adjacent the target area to perform a medical procedure;
• and
• passing at least one driving wire into the patient's body to engage the transducer to the track and extendable outside of a patient's body for controlling a movement, position, or orientation of the transducer on the track.

A system for use in a medical procedure comprising:

• means for attaching adjacent a target area inside a patient's body, wherein the means for attaching is foldable for deployment to a worksite, and unfoldable to a final shape and size after being located at the worksite inside the patient's body;
• means for anchoring the means for attaching to a tissue after the means for attaching is positioned adjacent the target area;
• and
• means for delivering energy to the target area from two or more positions along the means for attaching, the means for delivering energy mounted on the means for attaching after the means for attaching is anchored to the tissue.
