Abstract
An ablation instrument having a flexible portion at or near the distal portion of the instrument, is provided. The instrument includes an elongated tubular member having a steerable distal end configured to deflect, or otherwise direct, and properly position at least a portion of the distal portion, comprising an ablation device, during an ablation procedure. The instrument further includes a deflectable member which cooperates with the steering system allowing for the proper placement of the ablation device adjacent or proximate to the target tissue surface. The steering system may alternatively be incorporated into a separate guiding catheter as part of the catheter system.
