Abstract
A catheter suitable for use in applying ablation energy to body tissue or detecting electrical signals conducted within the body tissue is disclosed. The catheter has a deflectable distal tip section. At least one electrode is adapted to be disposed against body tissue for delivery of ablation energy thereto or for conduction of body tissue electrical signals. An actuation mechanism comprising first and second pull wires is adapted to curve a proximal segment in a first direction and to independently bend an intermediate segment in a second direction.
