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.
