    摘要： An electrophysiology catheter includes a tubular body having a proximal region, a neck region, and a distal region predisposed into a loop and including electrodes. A first deflection wire extends through at least a portion of the proximal region of the catheter body and includes a first flattened section, while a second deflection wire extends through the neck region and at least a portion of the distal region and includes a second flattened section within the neck region. A first activation wire is joined to the flattened section of the first deflection wire, while a second activation wire is joined to the flattened section of the second deflection wire. Thus, forces acting on the first and second activation wires, such as forces imposed by a handle-based actuator, are respectively transmitted to the first and second deflection wires, thereby deflecting the proximal and neck regions, respectively.

    摘要： A catheter includes a flexible tubing having a proximal end and a distal end. The catheter also includes an electrode assembly attached to the distal end of the flexible tubing and having a first magnet therein. The electrode assembly further includes an electrically conductive tip electrode and an electrically nonconductive coupler which is connected between the tip electrode and the distal end of the flexible tubing. The coupler and the tip electrode are coupled by an interlocking connection. The catheter also includes a second magnet spaced from the electrode assembly along a longitudinal axis of the tubing. The first magnet and the second magnet are responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.
