Steerable catheter design with ridge-enhanced molded articulated joint

An electrophysiology catheter (100) includes a tubular shaft (102) having a proximal portion, a distal portion having a distal end and a deflection region (108), the shaft defining a longitudinal axis and including an outer tubular sheath (402) and an articulation member (404) disposed within the sheath in the deflection region, the articulation member comprises a plurality of longitudinally arranged tubular segments (502), a plurality of first connecting segments (504) and a plurality of second connecting segments (506) wherein adjacent tubular segments are joined by respective ones of the first and second connecting segments, and wherein all of the first and second connection segments are disposed in a first plane extending through the longitudinal axis. A first reinforcement member (509) and a second reinforcement member (510) extend through the plurality of first connection segments and the plurality of second connection segments, respectively. 一种电生理学导管(100)包括管状轴(102)，所述轴具有近侧部分、具有远侧端部和偏转区域(108)的远侧部分，所述轴限定
