Patent ID: 8444637

Claim:
A steerable device for use in ablation therapy, comprising a shaft having a flexible distal region and a generally straight proximal region; one or more ablation cells disposed along the distal end; and a steerable deflection area defined as a longitudinally-extending portion of the flexible region, the steerable deflection region having a first anchor member attached to a distal portion of the flexible distal region, the anchor member having passageways for one or more pull wires extending from the proximal region to the distal region; wherein the steerable deflection region comprises an interlocking flex support member having a plurality of separate and distinct openings on an outer circumference of the steerable deflection region designed to permit deflection to a desired angle of deflection and maintain the integrity of the interior and exterior of the steerable deflection region, and wherein the steerable deflection region moves in response to actuation of the one or more pull wires.
