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: An irrigated catheter with uniform cooling and/or uniform fluid distribution in longitudinally spaced apart elution holes by varying the diameter of a fluid delivery lumen. A number of elution holes are provided in a tip region of a catheter body, and these elution holes are in fluid communication with the lumen through ducts. The fluid delivery lumen may be provided with a flow constrictor to restrict flow of fluid towards the distal region.
