Abstract:
1. A catheter for use in a vessel comprising: an elongate tubular member having a proximal end and a distal end and having a first lumen disposed therein; a tip electrode disposed at the distal end of the tubular member; a center strut extending from near the proximal end of the tip electrode through a deflectable distal portion of the elongate tubular member and having a first longitudinal edge and a second longitudinal edge; wherein the center strut is bonded to the elongate tubular member along substantially the entire length of the first longitudinal edge and the second longitudinal edge to create an inseparable composite structure from the center strut and the elongate tubular member having a cross-sectional moment of inertia that remains substantially constant along the entire length of the composite structure.
