Abstract: A catheter assembly includes a catheter body extending from a deflectable distal end to a proximal end, and the catheter body includes an actuator lumen. A housing is engaged to the proximal end of the catheter body. A flexible element extends from the housing through the actuator lumen to the deflectable distal end. The deflectable distal end is deflected by pushing and pulling of the flexible element. An actuator is movably coupled with the housing and connected to the flexible element. A tubular support is engaged around the flexible element and connected to the actuator, the tubular support moves with the actuator, and the tubular support substantially constrains lateral movement of the flexible element. The tubular support is telescopically received and engaged with an inner surface of the actuator lumen. The inner surface of the actuator lumen substantially constrains lateral movement of the tubular support and the flexible element.

Abstract: A catheter assembly includes a catheter body and housing attached to the catheter body proximal end, where an actuator lumen extends through the catheter body. A flexible element extends from an actuator member within the housing through the actuator lumen to a deflectable distal end. A first tubular support is provided that is coupled to the flexible element. A second tubular support is coupled with the first tubular support and slidably coupled to the flexible element. In one option, the first tubular support and second tubular support constrain lateral movement of the flexible element when the catheter assembly is operated.
