Abstract:
A catheter for ablating tissue comprising:a body portion;a distal end portion having a distal tip and including a plurality of distal end portion electrodes proximal to said distal tip, said distal end portion electrodes adapted to produce a substantially continuous, elongated, lesion in said tissue when energized with radio frequency (RF) energy, said distal tip including a distal tip electrode;a proximal deflection region between said body portion and said distal end portion;a distal deflection region near the distal tip of said distal end portion and in between said distal end portion electrodes and said distal tip electrode;a proximal deflection mechanism for deflecting said proximal deflection region and including at least a portion of the length of said proximal deflection mechanism located inside said body portion; anda distal deflection mechanism for deflecting said distal deflection region and including at least a portion of the length of said distal deflection mechanism located inside said body portion, wherein said proximal deflection region and said distal deflection region are deflected in the same direction.
