BALLOON CENTERED RADIALLY EXPANDING ABLATION DEVICE

摘要

A device and associated method for performing ablation procedures on anatomical structures accessible from within the chambers of the heart to form lesions that electrically isolate the tissue. The device including an ablation device having a catheter body concentrically formed with an outer sheath. The device also including a balloon used to perform a centering and anchoring function at an orifice within the cardiac myocardium. At least one ablation element can be positioned proximal to the balloon which can be radially deployed with respect to the central axis of the apparatus for creating a lesion at a lesion creation site in the heart wall.
