    Abstract: A catheter apparatus includes an elongated body having a distal portion including a distal end, a plurality of flexible segments, and at least one intermediate segment that is less flexible than the flexible segments. Adjacent flexible segments are spaced from each other longitudinally by the at least one intermediate segment. Each of the flexible segments include a sidewall having at least one elongated gap extending at least partially therethrough and forming interlocking members. The at least one intermediate segment is shorter than the flexible segments.

    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 translation: 在各种实施例中，提供了包括可扩张电极组件或篮子的导管。 在具体实施例中，篮子特别适用于在心脏内的一个或多个位置处映射电活动。 篮可以包括多个可弯曲或可偏转的臂。 至少一个臂可以在其长度上具有在肘部区域处的刚度或柔性的一个或多个不连续性的形式或其在臂长度上的其他柔性变化的形式的变化的柔性。 柔性的这种变化可允许臂具有不同的弯曲构型，或者通过在其长度上具有静态或接近静态的柔性或刚度的臂，可以更可靠地响应外部因素。
