Claim 0:
1. A steerable catheter comprising
a proximal catheter shaft section comprising a proximal end, a distal end, and a central lumen;
a distal deflectable section adjacent to the distal end of the proximal catheter shaft section, the distal deflectable section comprising a proximal end and a distal end;
a body compression coil surrounded by the proximal catheter shaft section and extending longitudinally through the central lumen from the proximal end of the proximal catheter shaft section to a first region at the proximal end of the distal deflectable section, the body compression coil comprising a central lumen;
a first pull wire extending longitudinally through the central lumen of the body compression coil from the proximal end of the proximal catheter shaft section to a second region at the proximal end of the distal deflectable section, the second region being distal to the first region;
a second pull wire extending longitudinally, parallel to the first pull wire, through the central lumen of the body compression coil from the proximal end of the proximal catheter shaft section to the second region at the proximal end of the distal deflectable section; and
a first pull wire compression coil surrounding the first pull wire within the body compression coil, the first pull wire compression coil extending longitudinally from the proximal end of the proximal catheter shaft section to the second region at the proximal end of the distal deflectable section.
