Abstract: An electrophysiology catheter comprising a tubular shaft, the shaft having a proximal portion, a distal portion having a distal end and a deflection region, the shaft defining a longitudinal axis and including an outer tubular jacket, and articulation member disposed within the jacket in the deflection region, the articulation member comprising a plurality of longitudinally-arranged tubular segments, a plurality of first connecting segments, and a plurality of second connecting segments, wherein adjacent tubular segments are joined by respective ones of the first and second connecting segments, and wherein all of the first and second connecting segments are disposed in a first plane extending through the longitudinal axis. A first reinforcing member and a second reinforcing member extend through the plurality of first and second connecting segments, respectively.
