ABSTRACT:
A cardiac ablation catheter includes a coil-like ablating element that is deployable from an elongate, flexible sheath. The ablating element, while in the deployed position, has a shape with at least one revolution oriented in a plane that is orthogonal to a longitudinal axis of the sheath. The catheter system is well-suited to ablate a circumferential region of tissue about a pulmonary vein or the posterior wall of the left atrium proximate the pulmonary vein os. The treated tissue region electrically isolates the atria from the pulmonary vein.
