Abstract
A catheter includes a steering tendon and a longitudinally adjustable core having a curved shape in the distal portion thereof. The steering tendon is attached to the distal-end region of the catheter sheath. The proximal end of the core is coupled to a positioning mechanism within the catheter handle and the distal end of the core floats within the catheter sheath. The position of the distal end of the core can be adjusted by advancing or retracting the positioning mechanism within the handle. Axial movement of the steering tendon in the proximal direction causes the distal-end region of the catheter sheath to deflect, while longitudinal adjustment of the curved core changes the deflection profile of the distal-end region of the catheter sheath.
