An apparatus, comprising:
- an elongate body proximal portion defining a lumen extending therethrough, a distal end and a proximal portion stiffness;
- an elongate body distal portion associated with the distal end of the elongate body proximal portion, the elongate body distal portion defining a distal end, a proximal end, a lumen extending therethrough, a length from the distal end to the proximal end, and a perimeter, and including at least first and second distal members that together form the elongate body distal portion, the first distal member defining a first distal member stiffness and the second distal member defining a second distal member stiffness less than the first distal member stiffness;
- and
- a steering wire having a distal portion operably connected to the elongate body distal portion.
