Abstract: A flexible tip electrode for an ablation catheter is disclosed. The catheter includes a catheter body and a hollow elongate tip electrode disposed at a distal end of the catheter body. The electrode includes a sidewall provided with one or more elongate gaps extending therethrough. The one or more elongate gaps providing flexibility in the sidewall for bending movement of the tip electrode relative to a longitudinal axis of the catheter body.

Abstract: 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.
