ABSTRACT:
An electrophysiology catheter (2) includes a handle (4) and a catheter shaft (6) having a flexible tip portion (22) with one or more electrodes (26, 28). A radial deflection wire (42) connects the tip portion to a first manipulator (10) at the handle to radially deflect the tip portion to a curved shape. A multifunction wire (60) extends from a second manipulator (11) at the handle to the tip portion. The second manipulator slides the multifunction wire longitudinally to position the distal end (64) of the multifunction wire along the multifunction lumen (38). The distal end of the multifunctional wire and the multifunction lumen are configured to provide interfering torquing surfaces (68, 70) so that when a third manipulator (12) rotates or torques the proximal end (62) of the multifunctional wire, the torquing force exerted between the interfering torquing surface causes lateral deflection of the radially curved tip portion. The catheter is constructed so that lateral deflection of the radially deflected tip portion is totally or at least substantially in-plane lateral deflection.
