Abstract
A catheter includes a steering system for manipulating the distal-end region of a sheath having a plurality of electrodes into direct contact with difficult-to-reach areas of the human body. The steering system includes a core base, a core distal tip, a stylet, a steering tendon, and a lever. Movement of the lever applies tension to the steering tendon causing the distal end of the sheath to deflect. A positioning mechanism, including a slidable controller, adjusts the position of the steering system relative to the catheter sheath to thereby provide multiple steering profiles.
