Abstract: A reinforced medical catheter (10) includes an elongated tubular outer wall reinforced by an internal helical coil spring (36). Successive loops of the coil spring adjoining the distal end are longitudinally separated, and a working lumen extends longitudinally through the catheter. A longitudinally extending reinforcing cable is captured in the tubular outer wall against the exterior of the coil spring. A steering cable operably interconnected with the distal end of the coil spring extends proximally from the distal end of the coil spring freely through the working lumen to the proximal end of the catheter. The reinforcing cable and the steering cable may constitute a continuous elongated filament. Withdrawing the steering cable proximally through the working lumen causes the distal tip of the catheter to be deflected laterally.
