Abstract: Cardiac ablation catheters include an outer balloon positioned at a distal end of the catheter and configured to have an inner balloon disposed therein. The outer balloon is inflated with a first fluid that has a temperature less than 100 degrees Celsius, while the inner balloon is inflated with heated vapor. An area of contact between the two balloons, comprising a surface area less than the total surface area of either balloon, creates a hot zone for ablating cardiac tissue through the transfer of thermal energy from the contact area to the cardiac tissue.
