ABSTRACT:
A reduced stiffness, bidirectionally deflecting catheter assembly (2) includes a handle (4) and flexible catheter shaft (6) with a tip section (12) secured to its distal end (14). The tip section has a radially offset, longitudinally extending core wire lumen (42) through which a tapered core wire (24), extending from a core wire manipulator (56) on the handle, passes. The core wire manipulator can be moved in two different directions (58, 60) to pull or push on the core wire to cause the tip section to deflect axially in opposite directions in the same plane. The ends of the core wire are non-rotatably secured to the handle and the tip section so that rotating the handle about its axis (63) causes the tip section to deflect laterally due to torsionally forces exerted on the tip section by both the catheter shaft and the core wire. The taper on the core wire determines the size and shape of the curved tip section when the tip is axially deflected.
