Abstract: A catheter that includes a mechanism for deflecting a distal portion of a catheter may include a deflection knob including a first thread, a rod including a second thread that is coupled to the first thread, and a puller wire that is connected to the rod. The rod may additionally include a pocket to which the puller wire may be connected via a joining feature that may be secured in the pocket and attached to a proximal end of the puller wire. The joining feature may include a first ferrule joined, e.g., crimped, to the proximal end of the puller wire and a second ferrule secured, e.g., bonded, in the pocket and joined, e.g., crimped, to the first ferrule.
