    • A deflectable catheter including an outer member having a proximal portion and a distal portion, an elongated column member extending distally from the outer member and an inner member positioned coaxial with the outer member and attached to the column member. The inner member extends distally of the outer member and has a distal tip portion. A reinforcement member is positioned over the column member to restrict axial movement of the column member such that when one of the inner member or outer member is moved with respect to the other, axial compression of the column member is restricted by the reinforcement member causing the distal tip portion of the inner member to deflect laterally.
    • 包括具有近端部分和远端部分的外部构件的可偏转导管,从所述外部构件向远侧延伸的细长柱构件和与所述外部构件同轴并附接到所述柱构件的内部构件。 内部构件在外部构件的远侧延伸并且具有远侧末端部分。 加强构件定位在柱构件上方以限制柱构件的轴向运动,使得当内构件或外构件中的一个相对于另一个移动时,柱构件的轴向压缩受到加强构件的限制, 内部构件的远侧末端部分侧向偏转。
