Abstract
Methods and apparatus are disclosed for forming annular lesions in tissue. The methods include introduction of an optical apparatus proximate to a tissue site, via, for example, a catheter. The optical apparatus includes a pattern-forming optical wave guide in communication with a light transmitting optical fiber. Energy is transmitted through the optical fiber, such that radiation is propagated through the optical fiber and the wave guide projects an annular light pattern, e.g., a circle or a halo.

21. A method of treating atrial fibrillation, comprising:
-
positioning a catheter ablation instrument within a heart in proximity to a pulmonary vein, the instrument having a catheter body with an energy emitter and a balloon;
inflating the balloon to provide a transmission pathway for projecting ablative energy from the energy emitter to the target region near a pulmonary vein; and
activating the energy emitter to project ablative energy to form a lesion in the target region of the heart. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
