The present invention provides a deflectable catheter (10) whose puller m ember (32) connections are accomplished with minimal, if any, surface deform ation which could otherwise accelerate breakage under tension. The catheter includes a molded member (60) that encases an end of a puller member to enab le connection of the end to a fixed or movable structure in the control hand le (16) without significant surface deformation in the puller member. The mo lded member is of a thermoplastic material that encases a preformed end of t he puller member, which may be a puller wire or a high modulus fiber materia l.
