    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： In various embodiments, a catheter comprising an expandable electrode assembly or basket is provided. In specific embodiments, the basket is particularly useful for mapping electrical activity at one or more locations within the heart. The basket can comprise a plurality of bendable or deflectable arms. At least one of the arms may have varied flexibility over its length in the form of one or more discontinuities of stiffness or flexibility at an elbow region or other variances in flexibility over the arm's length. Such variance in flexibility may allow the arm to assume a different bent configuration or respond to external factors more positively than possible with an arm having a static or near static flexibility or stiffness over its length.
