摘要
The present invention provides various embodiments of electrodes and/or electrode tips for use in connection with ablation catheters and ablation catheter systems. In an embodiment, an electrode tip for an ablation catheter is provided, comprising an electrode carrier, a first electrode, and second electrode, each adapted to direct energy is various directions and configured to be selectively activated. In another embodiment, an electrode is provided that comprises an electrode body having an insulated portion to protect adjacent tissue from ablation while further adapted to direct energy in a downward direction towards the target tissue. Other embodiments of electrodes and/or electrode tips providing ablative elements that are directed laterally are also disclosed. Moreover, embodiments of several types of electrodes and/or electrode tips, which may include positioning, orientation, irrigating, cooling, and deflecting features, whether provided individually or in various combinations, are also disclosed.
