    Abstract: Apparatus for irrigating an electrode of a catheter are disclosed. Among other things, a catheter is disclosed that comprises a shaft portion including a fluid passage to conduct fluid, an electrode coupled to a distal end of the shaft portion, and a handle portion coupled to a proximal end of the shaft portion. A portion of the fluid passage defines an opening in the shaft portion. The opening is constructed and arranged such that when fluid is conducted through the fluid passage, at least some of the fluid will contact the electrode after passing through the opening in the shaft portion.

    Abstract: A catheter includes a pull wire which extends through two different lumen and attaches to the distal end of the catheter at an off-axis location. By tensioning the pull wire, the catheter can assume various complex curves, depending on the respective lumen through which the pull wire passes.

    Abstract: Methods and apparatuses for manipulating an elongated flexible shaft of a catheter provide case and reliability of positioning electrodes against or near tissue. Dual-bend flexible distal tips (30) may be used in combination with flat wires. In some embodiments, flat wires which are free to rotate upon initial bending of shaft segments are employed. In some embodiments, one or more transition segments (48) are used to relocate the satellite lumen-to-main lumen transition of pull wires (42, 40) away from a change in shaft stiffness.
