Abstract
A catheter includes a steering mechanism for manipulating the distal end of the catheter to obtain a plurality of deflection profiles, and a torque transfer system at the distal portion to enhance torque transfer from the handle to the distal tip. The steering mechanism includes two steering tendons. The steering tendons are attached to the distal-end region of the catheter. The steering tendons may be located approximately angularly aligned, thus causing the deflection profiles to be unidirectional. Alternatively, the steering tendons may be located angularly separated from each other, thus causing the deflection profiles to be bidirectional. In other aspects, the torque transfer system includes a flat ribbon within the relatively flexible distal-end region to enhance torque transfer through the distal-end region of the catheter.
