    Abstract: A family of catheter electrode assemblies includes a flexible circuit having a plurality of electrical traces and a substrate; a ring electrode surrounding the flexible circuit and electrically coupled with at least one of the plurality of electrical traces; and an outer covering extending over at least a portion of the electrode. A non-contact electrode mapping catheter includes an outer tubing having a longitudinal axis, a deployment member, and a plurality of splines, at least one of the plurality of splines comprising a flexible circuit including a plurality of electrical traces and a substrate, a ring electrode surrounding the flexible circuit and electrically coupled with at least one of the plurality of electrical traces; and an outer covering extending over at least a portion of the ring electrode. A method of constructing the family of catheter electrode assemblies is also provided.

    Abstract: 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.

    Abstract: An electrophysiology catheter includes an elongate catheter body having an elastically-deformable distal region predisposed to assume a spiral shape and a first plurality of electrodes disposed thereon. Each of the first plurality of electrodes includes an electrically active region limited to the inner surface of the spiral shape for use in non-contact electrophysiology studies. A second plurality of electrodes may also be disposed on the distal region interspersed (e.g., alternating) with the first plurality of electrodes, with each of the second plurality of electrodes having an electrically active region extending into the outer surface of the spiral shape for use in contact electrophysiology studies. The distal region may be deformed into a straight configuration for insertion into and navigation through the patient's vasculature, for example via use of a tubular introducer. As the distal region deploys beyond the distal end of the introducer, it resumes the spiral shape.

    Abstract translation: 电生理导管包括细长的导管主体，其具有倾向于呈现螺旋形状的可弹性变形的远端区域和设置在其上的第一多个电极。 第一多个电极中的每一个包括限于用于非接触电生理学研究的螺旋形状的内表面的电活性区域。 第二多个电极也可以设置在与第一多个电极分散（例如交替）的远侧区域上，第二多个电极中的每一个具有延伸到螺旋形状的外表面中的电活性区域以供使用 接触电生理学研究。 远侧区域可以变形成直的构造，用于插入和导航通过患者的脉管系统，例如通过使用管状导引器。 当远端区域展开超过导引器的远端时，它恢复螺旋形状。
