    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: An EP catheter includes a tubular body having a proximal region, a neck region, and a distal portion predisposed into a single shallow helical fixed-diameter loop configuration and including a plurality of diagnostic electrodes. In deflectable catheter forms, at least one activation wire extends through at least a portion of the proximal region of the catheter body and is adapted to deflect the up to approximately 180 degrees relative to the proximal region. The catheter can be operated manually by a clinician or via a clinician-surrogate such as a computer processor-controlled surgical system. In addition, a variety of localization, visualization, and/or orientation-specific elements can be incorporated into the devices described, depicted, and claimed herein (e.g., metallic coil members, active impedance emitting or receiving electrodes, fluoroscopically opaque materials, and the like).

    摘要: A catheter maps an electrical conduction pattern in an annular region of a heart. The catheter has a tubular shaft that has a pre-shaped curved distal section adjacent the distal end thereof, and at least one lumen extending between the distal end and the proximal end of the shaft, with a plurality of electrodes disposed on the distal section. A handle is attached to the proximal end of the shaft, with a steering mechanism provided at the handle for adjusting the curvature of the distal section, and a deflection mechanism provided at the handle for deflecting the distal section. The electrodes are positioned in a parallel plane separate from the shaft when the distal section is undeflected.
