A malleable epicardial or endocardial probe that utilizes five electrodes to create uniform, reproducible linear lesions. No dragging is required, ensuring a consistent transmural lesion with no gaps. The COBRA Cooled™ uses advanced internal cooling technology to deliver more energy and overcome the heat sink affect while preventing the formation of coagulum at the tissue surface. The insulated tip allows the probe to create a full thickness isthmus lesion while not damaging the mitral annulus.
