Abstract
A catheter has a deflection beam with rectangular cross-section and a single continuous puller wire for predictable on-plane bi-directional deflection. The puller wire extends through spacers on opposite sides of the beam so the puller wire is maintained a predetermined separation distance from the beam surface. Tubular structures of the catheter body and the deflectable section are fused at a joint by C-shaped brackets mounted opposite surface of the beam to form a hollow body with holes into which thermoplastic materials covering the catheter body and the deflectable section can melt to form interlocking nodes. Elongated beam stiffeners can be mounted on the beam to provide different curve and deflection geometries.
