Abstract:
A suction assisted ablation device comprising:a support surface; at least three suction ports disposed adjacent the support surface, each of said at least three suction ports positioned adjacent the support surface in a linear arrangement with respect to each other and each of said at least three ports configured to pull a portion of epicardial tissue adjacent to each of the suction ports into the suction ports at an applied suction in the range of about 200 to 400 mm Hg; a first elongated electrode disposed adjacent the support surface and extending adjacent a first side of each of the suction ports; and a second elongated electrode disposed adjacent the support surface and extending adjacent a second side of each of the suction ports, the first and second electrodes disposed adjacent the support surface such that a linear transmural lesion may be formed in tissue within the suction ports by applying radio frequency energy to the tissue via the first and second electrodes.
