ABSTRACT:
An electrode tip assembly attachable to the end of a catheter for supporting a tip electrode for percutaneous insertion into a living body having a steering mechanism includes an elongated body bendable in response to external forces to steer the tip electrode. The body is connected at its distal end to the tip electrode. At least one steering wire is attached to the elongated body for transmitting bending force to the body from a remote control mechanism. An movable stiffening member, preferably in the form of a sleeve or rod provides a variable fulcrum for bending of the body in response to an applied bending force. A control stylet or sleeve extends through the catheter and is attached to the stiffening member for moving the stiffening member in a distal/proximal direction or for rotating it relative to the body.
